Anxiety disorders: An overview

Anxiety is the commonest psychiatric symptom in clinical practice and anxiety disorders are one of the commonest psychiatric disorders in the general population. Anxiety is a ‘normal’ phenomenon, which is characterized by a state of apprehension or unease arising out of anticipation of danger. Anxiety is often differentiated from fear, as fear is an apprehension in response to an external danger while in anxiety the danger is largely unknown (or internal). Normal anxiety becomes pathological when it causes significant subjective distress and/or impairment in the functioning of an individual.



Three factors- duration, intensity, and frequency- distinguish normal, adaptive anxiety from abnormal, pathological anxiety. As such, abnormal anxiety is different from normal anxiety because it is disproportionate to the situation that elicited the anxious response. When the intensity, duration, and/or frequency of anxiety become distressful and chronic, such that it interferes with a person’s functioning, it is often referred to as pathological anxiety. Anxiety disorders represent variant forms of this pathological anxiety.


Therefore, the difference between normal anxiety and abnormal anxiety is this: anxiety is considered normal and adaptive when it serves to improve peoples’ functioning or wellbeing. In contrast, abnormal anxiety is a chronic condition that impairs peoples’ functioning and interferes with their well-being. This impairment causes them significant distress.

When the source of danger is obvious, the experienced emotion has been called fear (e.g., “I’m afraid of snakes”). With anxiety, however, we frequently cannot specify clearly what the danger is (e.g., “I’m anxious about my parents’ health”).

Fear is a basic emotion (shared by many animals) that involves activation of the “fight-or-flight” response of the autonomic nervous system. This is an almost instantaneous reaction to any imminent threat such as a dangerous predator or someone pointing a loaded gun.


The symptoms of a panic attack are nearly identical to those experienced during a state of fear except that panic attacks are often accompanied by a subjective sense of impending doom, including fears of dying, going crazy, or losing control. These latter cognitive symptoms do not generally occur during fear states.

Thus, fear and panic have three components:

  • Cognitive/subjective components (“I feel afraid/terrified”; “I’m going to die”)
  • Physiological components (such as increased heart rate and heavy breathing)
  • Behavioral components (a strong urge to escape or flee; Lang, 1968, 1971).


Generalized Anxiety Disorder (GAD)

Generalized anxiety disorder, commonly referred to as GAD, is a disorder characterized by an underlying excessive worry related to a wide range of events or activities. While many individuals experience some levels of worry throughout the day, individuals with GAD experience worry of a greater intensity and for longer periods of times than the average person. Additionally, they are often unable to control their worry through various coping strategies, which directly interferes with their ability to engage in daily social and occupational tasks. Individuals with GAD will also experience somatic symptoms during intensive periods of anxiety.

This is characterised by an insidious onset in the third decade and a stable, usually chronic course which may or may not be punctuated by repeated panic attacks (episodes of acute anxiety). The symptoms of anxiety should last for at least a period of 6 months for a diagnosis of generalised anxiety disorder to be made. The one year prevalence of generalised anxiety disorder in the general population is about 2.5-8%. It is the commonest psychiatric disorder in the population. As anxiety is a cardinal feature of almost all psychiatric disorders, it is very important to exclude other diagnoses. The most important differential diagnosis is from depressive disorders and organic anxiety disorder.

Specific Phobia

Specific phobia is distinguished by an individual’s fear or anxiety specific to an object or a situation. While the amount of fear or anxiety related to the specific object or situation varies among individuals, it also varies related to the proximity of the object/situation. When individuals are face-to-face with their specific phobia, immediate fear is present. It should also be noted that these fears are more excessive and more persistent than a “normal” fear, often severely impacting one’s daily functioning (APA, 2013).

Individuals can experience multiple specific phobias at one time. In fact, nearly 75% of individuals with a specific phobia report fear in more than one object (APA, 2013).  When making a diagnosis of specific phobia, it is important to identify the specific phobic stimulus. Among the most commonly diagnosed specific phobias are animals, natural environments (height, storms, water), blood-injection-injury (needles, invasive medical procedures), or situational (airplanes, elevators, enclosed places; APA, 2013). Given the high percentage of individuals who experience more than one specific phobia, all specific phobias should be listed as a diagnosis in efforts to identify an appropriate treatment plan.


Similar to GAD, agoraphobia is defined as an intense fear triggered by a wide range of situations; however, unlike GAD, agoraphobia’s fears are related to situations in which the individual is in public situations where escape may be difficult. In order to receive a diagnosis of agoraphobia, there must be a presence of fear in at least two of the following situations: using public transportation such as planes, trains, ships, buses; being in large, open spaces such as parking lots or on bridges; being in enclosed spaces like stores or movie theaters; being in a large crowd similar to those at a concert; or being outside of the home in general (APA, 2013). When an individual is in one (or more) of these situations, they experience significant fear, often reporting panic-like symptoms (see Panic Disorder). It should be noted that fear and anxiety related symptoms are present every time the individual is presented with these situations. Should symptoms only occur occasionally, a diagnosis of agoraphobia is not warranted.

Due to the intense fear and somatic symptoms, individuals will go to great lengths to avoid these situations, often preferring to remain within their home where they feel safe, thus causing significant impairment in one’s daily functioning. They may also engage in active avoidance, where the individual will intentionally avoid agoraphobic situations. These avoidance behaviors may be behavioral, including having food delivery to avoid going to grocery store or only taking a job that does not require the use of public transportation, or cognitive, by using distraction and various other cognitive techniques to successfully get through the agoraphobic situation.

Social Anxiety Disorder

For social anxiety disorder, the anxiety is directed toward the fear of social situations, particularly those in which an individual can be evaluated by others. More specifically, the individual is worried that they will be judged negatively and viewed as stupid, anxious, crazy, boring, unlikeable, or boring to name a few. Some individuals report feeling concerned that their anxiety symptoms will be obvious to others via blushing, stuttering, sweating, trembling, etc. These fears severely limit an individual’s behavior in social settings. For example, and individual may avoid holding drinks or plates if they know they will tremble in fear of dropping or spilling food/water. Additionally, if one is known to sweat a lot in social situations, they may limit physical contact with others, refusing to shake hands.

Unfortunately, for those with social anxiety disorder, all or nearly all social situations provoke this intense fear. Some individuals even report significant anticipatory fear days or weeks before a social event is to occur. This anticipatory fear often leads to avoidance of social events in some individuals; others will attend social events with a marked fear of possible threats. Because of these fears, there is a significant impact in one’s social and occupational functioning.

It is important to note that the cognitive interpretation of these social events is often excessive and out of proportion to the actual risk of being negatively evaluated. There are instances where one may experience anxiety toward a real threat such as bullying or ostracizing. In this instance, social anxiety disorder would not be diagnosed as the negative evaluation and threat are real.

Panic Disorder

Panic disorder consists of a series of recurrent, unexpected panic attacks coupled with the fear of future panic attacks. A panic attack is defined as a sudden or abrupt surge or fear or impending doom along with at least four physical or cognitive symptoms (listed below). The symptoms generally peak within a few minutes, although it seems much longer for the individual experiencing the panic attack.

There are two key components to panic disorder—the attacks are unexpected meaning there is nothing that triggers them, and they are recurrent meaning they occur multiple times. Because these panic attacks occur frequently and essentially “out of the blue,” they cause significant worry or anxiety in the individual as they are unsure of when the next attack will occur. In some individuals, significant behavioral changes such as fear of leaving their home or attending large events occurs as the individual is fearful an attack will happen in one of these situations, causing embarrassment. Additionally, individuals report worry that other’s will think they are “going crazy” or losing control if they were to observe an individual experiencing a panic attack. Occasionally, an additional diagnosis of agoraphobia is given to an individual with panic disorder if their behaviors meet diagnostic criteria for this disorder as well (see more below).

The frequency and intensity of these panic attacks vary widely among individuals. Some people report panic attacks occurring once a week for months on end, others report more frequent attacks multiple times a day, but then experience weeks or months without any attacks. Intensity of symptoms also varies among individuals, with some patients reporting experiencing nearly all 14 symptoms and others only reporting the minimum 4 required for the diagnosis. Furthermore, individuals report variability within their own panic attack symptoms, with some panic attacks presenting with more symptoms than others. It should be noted that at this time, there is no identifying information (i.e. demographic information) to suggest why some individuals experience panic attacks more frequently or more severe than others.


Generalized anxiety disorder

The prevalence rate for generalized anxiety disorder is estimated to be 3% of the general population, with nearly 6% of individuals experiencing GAD sometime during their lives. While it can present at any age, it generally appears first in childhood or adolescence. Similar to most anxiety related disorders, females are twice as likely to be diagnosed with GAD as males (APA, 2013).

Specific phobia

The prevalence rate for specific phobias is 7-9% within the united states. While young children have a prevalence rate of approximately 5%, teens have nearly a double prevalence rate than that of the general public at 16%. There is a 2:1 ratio of females to males diagnosed with specific phobia; however, this rate changes depending on the different phobic stimuli. More specifically, animal, natural environment, and situational specific phobias are more commonly diagnosed in females, whereas blood-injection-injury phobia is reportedly diagnosed equally between genders.


The yearly prevalence rate for agoraphobia across the lifespan is roughly 1.7%. Females are twice as likely as males to be diagnosed with agoraphobia (notice the trend…). While it can occur in childhood, agoraphobia typically does not develop until late adolescence/early adulthood and typically tapers off in later adulthood.

Social anxiety disorder

The overall prevalence rate of social anxiety disorder is significantly higher in the United States than other countries would wide, with an estimated 7% of the US population diagnosed with a social anxiety disorder. Within the US, the prevalence rate remains the same among children through adults; however, there appears to a significant decrease in the diagnosis of social anxiety disorder among older individuals. With regards to gender, there is a higher diagnosis rate in females than males. This gender discrepancy appears to be larger in children/adolescents than adults.

Panic disorder

Prevalence rates for panic disorder are estimated at around 2-3% in adults and adolescents. Higher rates of panic disorder are found in American Indians and non-Latino whites. Females are more commonly diagnosed than males with a 2:1 diagnosis rate—this gender discrepancy is seen throughout the lifespan. Although panic disorder can occur in young children, it is generally not observed in individuals younger than 14 years of age.


Generalized anxiety disorder

There is a high comorbidity between generalized anxiety disorder and the other anxiety related disorders, as well as major depressive disorder, suggesting they all share common vulnerabilities, both biological and psychological.

Specific phobia

Seeing as the onset of specific phobias occurs at a younger age than most other anxiety disorders, it is generally the primary diagnosis with the occasional generalized anxiety disorder comorbid diagnosis. It should be noted that children/teens diagnosed with a specific phobia are at an increased risk for additional psychopathology later in life. More specifically, other anxiety disorders, depressive disorders, substance related disorders and somatic symptom disorders.


Similar to the other anxiety disorders, comorbid diagnoses include other anxiety disorders, depressive disorders, and substance use disorders, all of which typically occur after the onset of agoraphobia (APA, 2013). Additionally, there is also a high comorbidity between agoraphobia and PTSD. While agoraphobia can be a symptom of PTSD, an additional diagnosis of agoraphobia is made when all symptoms of agoraphobia are met in addition to the PTSD symptoms.

Social anxiety disorder

Among the most common comorbid diagnoses with social anxiety disorder are other anxiety related disorders, major depressive disorder, and substance related disorders. Generally speaking, social anxiety disorders will precede that of other mental health disorders, with the exception of separation anxiety disorder and specific phobia, seeing as these two disorders are more commonly diagnosed in childhood (APA, 2013). The high comorbidity rate among anxiety related disorders and substance related disorders is likely related to the efforts of self-medicating. For example, and individual with social anxiety disorder may consume larger amounts of alcohol in social settings in efforts to alleviate the anxiety of the social situation.

Panic disorder

Panic disorder rarely occurs in isolation, as many individuals also report symptoms of other anxiety disorders, major depression, and substance abuse. There is mixed evidence as to whether panic disorder precedes other comorbid psychological disorders—estimates suggest that 1/3 of individuals with panic disorder will experience depressive symptoms prior to panic symptoms whereas the remaining 2/3 will experience depressive symptoms concurrently or after the onset of panic disorder (APA, 2013).

Unlike some of the other anxiety disorders, there is a high comorbid diagnosis with general medical symptoms. More specifically, individuals with panic disorder are more likely to report somatic symptoms such as dizziness, cardia arrhythmias, asthma, irritable bowel syndrome, and hyperthyroidism (APA, 2013). The relationship between panic symptoms and somatic symptoms is unclear; however, there does not appear to be a direct medical cause between the two.



Biological – Genetic influences. While genetics have been known to contribute to the presentation of anxiety symptoms, the interaction between genetics and stressful environmental influences appears to actually account for more of anxiety disorders than genetics alone (Bienvenu, Davydow, & Kendler, 2011). The quest to identify specific genes that may predispose individuals to develop anxiety disorders has lead researchers to the serotonin transporter gene (5-HTTLPR). Mutation of the 5-HTTLPR gene has been found to be related to a reduction in serotonin activity and an increase in anxiety-related personality traits (Munafo, Brown, & Hairiri, 2008).

Biological – Neurobiological structures. Researchers have identified several brain structures and pathways that are likely responsible for anxiety responses. Among those structures is the amygdala, the area of the brain that is responsible for storing memories related to emotional events (Gorman, Kent, Sullivan, & Coplan, 2000). When presented with a fearful situation, the amygdala initiates a reaction in efforts to prepare the body for a response. First, the amygdala triggers the hypothalamic-pituitary-adrenal (HPA) axis to prepare for immediate action— either to fight or flight. The second pathway is activated by the feared stimulus itself, by sending a sensory signal to the hippocampus and prefrontal cortex, for determination if threat is real or imagined. If it is determined that no threat is present, the amygdala sends a calming response to the HPA axis, thus reducing the level of fear. If there is a threat present, the amygdala is activated, producing a fear response.

Specific to panic disorder is the implication of the locus coeruleus, the brain structure that serves as an “on-off” switch for norepinephrine neurotransmitters. It is believed that increased activation of the locus coeruleus results in panic like symptoms; therefore, individuals with panic disorder may have a hyperactive locus coeruleus, leaving them more susceptible to experience more intense and frequent physiological arousal than the general public (Gorman, Kent, Sullivan, & Coplan, 2000). This theory is supported by studies in which individuals experienced increased panic symptoms following injection of norepinephrine (Bourin, Malinge, & Guitton, 1995).

Unfortunately, norepinephrine and the locus coeruleus fail to fully explain the development of panic disorder, as treatment would be much easier if only norepinephrine was implicated. Therefore, researchers argue that a more complex neuropathway is likely implicated in the development of panic disorder. More specifically, the corticostriatal-thalamocortical (CSTC) circuit, also known as the fear-specific circuit, is theorized as a major contributor to panic symptoms (Gutman, Gorman, & Hirsch, 2004). When an individual is presented with a frightening object or situation, the amygdala is activated, sending a fear response to the anterior cingulate cortex and the orbitofrontal cortex. Additional projection from the amygdala to the hypothalamus activates endocrinologic responses to fear- releasing adrenaline and cortisol to help prepare the body to fight or flight (Gutman, Gorman, & Hirsch, 2004). This complex pathway supports the theory that panic disorder is mediated by several neuroanatomical structures and their associated neurotransmitters.


Psychological – Cognitive. The cognitive perspective on the development of anxiety related disorders centers around dysfunctional thought patters. As seen in depression, maladaptive assumptions are routinely observed in individuals with anxiety related disorders, as they often engage in interpreting events as dangerous or overreacting to potential stressful events, which contributes to a heightened overall anxiety level. These negative appraisals, in combination with a biological predisposition to anxiety likely contribute to the development of anxiety symptoms (Gallagher et al., 2013).

Sensitivity to physiological arousal not only contributes to anxiety disorders in general, but also for panic disorder where individuals experience various physiological sensations and misinterpret them as catastrophic. One explanation for this theory is that individuals with panic disorder are actually more susceptible to more frequent and intensive physiological symptoms than the general public (Nillni, Rohan, & Zvolensky, 2012). Others argue that these individuals have had more trauma-related experiences in the past, and therefore, are quick to misevaluate their symptoms as a potential treat. This misevaluation of symptoms as impending disaster likely maintain symptoms as the cognitive misinterpretations to physiological arousal creates a negative feedback loop, leading to more physiological changes.

Social anxiety is also largely explained by cognitive theorists. Individuals with social anxiety disorder tend to hold unattainable or extremely high social beliefs and expectations. Furthermore, they often engage in preconceived maladaptive assumptions that they will behave incompetently in social situations, and that their behaviors will lead to terrible consequences. Because of these beliefs, they anticipate social disasters will occur and therefore, avoid social encounters (or limit them to close friends/family members) in efforts to prevent the disaster (Moscovitch et al., 2013). Unfortunately, these cognitive appraisals are not only isolated to before and during the event. Individuals with social anxiety disorder will also evaluate the social event after it has taken place, often obsessively reviewing the details. This overestimation of social performance negatively reinforces future avoidance of social situations.

Psychological – Behavioral. The behavioral explanation for the development of anxiety disorders is largely reserved for phobias- both specific and social phobia. More specifically, behavioral theorists focus on classical conditioning– when two events that occur close together become strongly associated with one another, despite their lack of causal relationship. Watson and Rayner’s (1920) infamous Little Albert experiment is an example of how classical conditioning can be used to induce fear through associations. In this study, Little Albert developed a fear of white rats by pairing a white rate with a loud sound. This experiment, although lacking ethical standards, was ground breaking in the development of learned behaviors. Over time, researchers have been able to replicate these findings (in more ethically sound ways) to provide further evidence of the role of classical conditioning in the development of phobias.

Psychological – Modeling is another behavioral explanation of the development of specific and social phobias. In modeling, an individual acquires a far though observation and imitation (Bandura & Rosenthal, 1966). For example, when a young child observes their parent display irrational fears of an animal, the child may then begin to display similar behaviors. Similarly, observing another individual being ridiculed in a social setting may increase the chances of the development of social anxiety, as the individual may become fearful that they would experience a similar situation in the future. It is speculated that the maintenance of these phobias is due to the avoidance of the feared item or social setting, thus preventing the individual from learning that the item/social situation is not something that should be feared.

While modeling and classical conditioning largely explain the development of phobias, there is some speculation that the accumulation of a large number of these learned fears will develop into GAD. Through stimulus generalization, or the tendency for the conditioned stimulus to evoke similar responses to other conditions, a fear of one item (such as the dog) may become generalized to other items (such as all animals). As these fears begin to grow, a more generalized anxiety will present, as opposed to a specific phobia.


Seeing how prominent the biological and psychological constructs are in explaining the development of anxiety related disorders, we also need to review the social constructs that contribute and maintain anxiety disorders. While characteristics such as living in poverty, experiencing significant daily stressors, and increased exposure to traumatic events are all identified as major contributors to anxiety disorders, additional sociocultural influences such as gender and discrimination have also received great attention, particularly because due to the epidemiological nature of the disorder.

Gender has largely been researched within anxiety disorders due to the consistent discrepancy in diagnosis rate between men and women. As previously discussed, women are routinely diagnosed with anxiety disorders more often than men, a trend that is observed throughout the entire lifespan. One potential explanation for this discrepancy is the influence of social pressures on women. Women are more susceptible to experience traumatic experiences throughout their life, which may contribute to anxious appraisals of future events. Furthermore, women are more likely to use emotion-focused coping, which is less effective in reducing distress than problem-focused coping (McLean & Anderson, 2009). These factors may increase levels of stress hormones within women that leave them susceptible to develop symptoms of anxiety. Therefore, it appears a combination of genetic, environmental, and social factors may explain why women tend to be diagnosed more often with anxiety related disorders.

Exposure to discrimination and prejudice, particularly relevant to ethnic minority and other marginalized groups, can also impact an individual’s anxiety level. Discrimination and prejudice contribute to negative interactions, which is directly related to negative affect and an overall decline in mental health (Gibbons et al., 2014). The repeated exposure to discrimination and prejudice over time can lead to fear responses in individuals, along with subsequent avoidance of social situations in efforts to protect themselves emotionally.


Generalized Anxiety Disorder

Psychopharmacology. Benzodiazepines, a class of sedative-hypnotic drugs that will be discussed in more detail in the Substance Abuse chapter, originally replaced barbiturates as the leading anti-anxiety medication due to their less addictive nature, yet equally effective ability to calm individuals at low dosages. Unfortunately, as more research was done on benzodiazepines, serious side effects as well as physical dependence of benzodiazepines at large dosages has routinely been documented (NIMH, 2013). Due to these negative effects, selective serotonin-reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are generally considered to be first-line medication options for those with GAD. Findings indicate a 30-50% positive response rate to these psychopharmacological interventions (Reinhold & Rickels, 2015). Unfortunately, none of these medications continue to provide any benefit once they are stopped; therefore, other more effective treatment options such as CBT, relaxation training, and biofeedback are often encouraged before the use of pharmacological interventions.

Rational-Emotive therapy. Rational emotive therapy was developed by Albert Ellis in the mid-1950s as one of the first forms of cognitive-behavioral therapy. Ellis proposed that individuals were not aware of the effect their negative thoughts had on their behaviors and various relationships and thus, identified a treatment aimed to address these thoughts in effort to provide relief to those suffering from anxiety and depression. The goal of rational emotive therapy is to identify irrational, self-defeating assumptions, challenge the rationality of those assumptions, and to replace them with new more productive thoughts and feelings. It is proposed that through identifying and replacing these assumptions that one will experience relief of GAD symptoms (Ellis, 2014).

Cognitive Behavioral Therapy (CBT). CBT is discussed in great detail in the Depression chapter; however, it is also among the most effective treatment options for a variety of anxiety related disorders, including GAD. In fact, findings suggest 60 percent of individuals report a significant reduction/elimination in anxious thoughts one year post treatment (Hanrahan, Field, Jones, & Davy, 2013). The fundamental goal of CBT is a combination of cognitive and behavioral strategies aimed to identify and restructure maladaptive thoughts while also providing opportunities to utilize these more effective thought patterns through exposure based experiences. Through repetition, the individual will be able to identify and replace anxious thoughts outside of therapy sessions, ultimately reducing their overall anxiety levels (Borkovec, & Ruscio, 2001).

Biofeedback. Biofeedback provides a visual representation of a patient’s physiological arousal. To achieve this feedback, a patient is connected to a computer that provides continuous information of their physiological states. There are several ways a patient can be connected to the computer. Among the most common is electromyography (EMG). EMG measures the amount of muscle activity currently experienced by the individual. An electrode is placed on a patient’s skin just above a major muscle group- commonly the forearm or the forehead. Other common areas of measurement are electroencephalography (EEG) which measures the neurofeedback or brain activity; heart rate variability (HRV) which measures autonomic activity such as heart rate or blood pressure; and galvanic skin response (GSR) which measures sweat.

Once the patient is connected to the biofeedback machine, the clinician is able to walk the patient through a series of relaxation scripts or techniques as the computer simultaneously measures the changes in muscle tension. The theory behind biofeedback is that in providing a patient with a visual representation of changes in their physiological state, they become more skilled at voluntarily reducing their physiological arousal, and thus, their overall sense of anxiety or stress. While research has identified only a modest effect of biofeedback on anxiety levels, patients do report a positive experience with the treatment due to the visual feedback of their physiological arousal (Brambrink, 2004).

Specific Phobias

Exposure treatments. While there are many treatment options for specific phobias, research routinely supports the behavioral techniques as the most effective treatment strategies. Seeing as the behavioral theory suggests phobias are developed via classical conditioning, the treatment approach revolves around breaking the maladaptive association developed between the object and fear. This is generally accomplished through exposure treatments. As the name implies, the individual is exposed to their feared stimuli. This can be done in several different approaches: systematic desensitization, flooding, and modeling.

Systematic desensitization is an exposure technique that is utilizes relaxation strategies to help calm the individual as they are presented with the fearful object. The notion behind this technique is that both fear and relaxation cannot exist at the same time; therefore, the individual is taught how to replace their fearful reaction with a calm, relaxing reaction.

To begin, the patient, with assistance from the clinician, will identify a fear hierarchy, or a list of feared objects/situations ordered from least fearful to most fearful. After learning intensive relaxation techniques, the clinician will present items from the fear hierarchy- starting from the least fearful object/subject- while the patient practices using the learned relaxation techniques. The presentation of the feared object/situation can be in person- in vivo exposure or it can be imagined- imaginal exposure. Imaginal exposure tends to be less intensive than in vivo exposure; however, it is less effective than in vivo exposure in eliminating the phobia. Depending on the phobia, in vivo exposure may not be an option, such as with a fear of a tornado. Once the patient is able to effectively employ relaxation techniques to reduce their fear/anxiety to a manageable level, the clinician will slowly move up the fear hierarchy until the individual does not experience excessive fear of all objects on the list.

Flooding. Another exposure technique is flooding. In flooding, the clinician does not utilize a fear hierarchy, but rather repeatedly exposes the individual to their most feared object/subject. Similar to systematic desensitization, flooding can be done in either in vivo or imaginal exposure. Clearly, this technique is more intensive than the systematic or gradual exposure to feared objects. Because of this, patients are at a greater likelihood of dropping out of treatment, thus not successfully overcoming their phobias.

Modeling. Finally, modeling is another common technique that is used to treat phobia disorders (Kelly, Barker, Field, Wilson, & Reynolds, 2010). In this technique, the clinician approaches the feared object/subject while the patient observes. Like the name implies, the clinician models appropriate behaviors when exposed to the feared stimulus, implying that the phobia is irrational. After modeling several times, the clinician encourages the patient to confront the feared stimulus with the clinician, and then ultimately, without the clinician.


Similar to the treatment approaches for specific phobias, exposure based treatment techniques are among the most effective treatment options for individuals with agoraphobia; however, unlike the high success rate in specific phobias, exposure based treatment for agoraphobia has been less effective in providing complete relief of the disorder. The success rate may be impacted by the high comorbidity rate of agoraphobia and panic disorder. Because of the additional presentation of panic symptoms, exposure based treatments alone are not the most effective in eliminating symptoms as residual panic symptoms often remain (Craske & Barlow, 2014). Therefore, the best treatment approach for those with agoraphobia and panic disorder is a combination of exposure and CBT techniques (see Panic disorder treatment).

For individuals with agoraphobia without panic symptoms, the use of group therapy in combination with individual exposure based therapy has been identified as a successful treatment option. The group therapy format allows the individual to engage in exposure based field trips to various community locations, while also maintaining a sense of support and security from a group of individuals whom they know. Research indicates that this exposure based type of treatment provides improvement form nearly 60 to 80 percent of patients with agoraphobia; however, there is a relatively high rate of partial relapse suggesting that long-term treatment or booster sessions at minimum should be continued for several years (Craske & Barlow, 2014).

Social Anxiety Disorder

Exposure. A hallmark treatment approach for all anxiety related disorders is exposure. Specific to social anxiety disorder, the individual is encouraged to engage in social situations where they are likely to experience increased anxiety. Initially, the clinician will engage in role-playing of various social situations with the patient so that the patient can practice social interactions in a safe, controlled environment (Rodebaugh, Holaway, & Heimberg, 2004). As the patient becomes habituated to the interaction with the clinician, the clinician and patient may venture outside of the treatment room and engage in social settings with random strangers at various locations such as fast food restaurants, local stores, libraries, etc. The patient is encouraged to continue with these exposure based social interactions outside of treatment to help reduce anxiety related to social situations.

Social skills training. This treatment is specific to social anxiety disorder as it focuses on skill deficits or inadequate social interactions displayed by the patient that contributes to the negative social experiences and anxiety. In session, the clinician may use a combination of skills such as modeling, corrective feedback, and positive reinforcement to provide feedback and encouragement to the patient of regarding their behavioral interactions (Rodebaugh, Holaway, & Heimberg, 2004). By incorporating the clinician’s feedback into their social repertoire, the patient can engage in positive social behaviors outside of the treatment room in hopes to improve their overall social interactions and reduce ongoing social anxiety.

Cognitive restructuring. While exposure and social skills training are helpful treatment options, research routinely supports the need to incorporate cognitive restructuring as an additive component in treatment to provide substantial symptom reduction. Similar to cognitive restructuring previously discussed in the Depression chapter, the clinician will work with the therapist to identify negative, automatic thoughts that contribute to the distress in social situations. The clinician can then help the patient establish new, positive thoughts to replace these negative thoughts. Research indicates that implementing cognitive restructuring techniques before, during, and after exposure sessions enhances the overall effects of treatment of social anxiety disorder (Heimberg & Becker, 2002).

Panic Disorder

Cognitive Behavioral Therapy (CBT). CBT is the most effective treatment option for individuals with panic disorder as the focus is on correcting misinterpretations of bodily sensations (Craske & Barlow, 2014). Nearly 80 percent of people with panic disorder report complete remission of symptoms after mastering the following five components of CBT for Panic disorder (Craske & Barlow, 2014).

Psychoeducation. Treatment begins by educating the patient on the nature of panic disorder, the underlying causes of panic disorder, as well as the mechanisms that maintain the disorder such as the physical, cognitive, and behavioral response systems (Craske & Barlow, 2014). This part of treatment is fundamental in correcting any myths or misconceptions about panic symptoms, as they often contribute to the exacerbation of panic symptoms.

Self-monitoringSelf-monitoring, or the awareness of self-observation, is essential to the CBT treatment process for panic disorder. In this part of treatment, the individual is taught to identify the physiological cues immediately leading up to and during a panic attack.  The patient is then encouraged to identify and document the thoughts and behaviors associated with these physiological symptoms. By bringing awareness to the symptoms, as well as the relationship between physical arousal and cognitive/behavioral responses, the patient is learning the fundamental processes in which they can manage their panic symptoms (Craske & Barlow, 2014).

Relaxation training. Similar to that in exposure based treatment for phobias, prior to engaging in exposure training, the individual must learn a relaxation technique to apply during onset of panic attacks. While breathing training was once included as the relaxation training technique of choice for panic disorder due to the high report of hyperventilation during panic attacks, more recent research has failed to support this technique as effective in the use of panic disorder (Schmidt et al., 2000). Findings suggest that breathing retraining is more commonly misused as a means for avoiding physical symptoms as opposed to an effective physiological response to stress (Craske & Barlow, 2014).

Progressive muscle relaxation. To replace the breathing retraining, Craske & Barlow (2014) suggest progressive muscle relaxation (PMR). In progressive muscle relaxation, the patient learns to tense and relax various large muscle groups throughout the body. Generally speaking, the patient is encouraged to start at either the head or the feet, and gradually work their way up through the entire body, holding the tension for roughly 10 seconds before relaxing. The theory behind PMR is that in tensing the muscles for a prolonged period of time, the individual exhausts those muscles, forcing them (and eventually) the entire body to engage in relaxation (McCallie, Blum, & Hood, 2006).

Cognitive restructuring. Cognitive restructuring, or the ability to recognize cognitive errors and replace them with alternate, more appropriate thoughts, is likely the most powerful part of CBT treatment for panic disorder, aside from the exposure part. Similar to the discussion in the Depression chapter, cognitive restructuring involves identifying the role of thoughts in generating and maintaining emotions. The clinician encourages the patient to view these thoughts as “hypotheses” as opposed to fact, which allows the thoughts to be questioned and challenged. This is where the detailed recordings in the self-monitoring section of treatment is helpful. By discussing specifically what the patient has recorded for the relationship between physiological arousal and thoughts/behaviors, the clinician is able to help the patient restructure the maladaptive thought processes to more positive thought processes which in return, helps to reduce fear and anxiety.

Exposure. As discussed in detail above in the specific phobia section, the patient is next encouraged to engage in a variety of exposure techniques such as in vivo exposure and interoceptive exposure, while also incorporating the cognitive restructuring and relaxation techniques previously learned in efforts to reduce and eliminate ongoing distress.  Interoceptive exposure involves inducing panic specific symptoms to the individual repeatedly, for a prolonged time period, so that maladaptive thoughts about the sensations can be disconfirmed and conditional anxiety responses are extinguished (Craske & Barlow, 2014). Some examples of these exposure techniques are spinning a patient repeatedly in a chair to induce dizziness and breathing in a paper bag to induce hyperventilation. These treatment approaches can be presented in a gradual manner; however, the patient must endure the physiological sensations for at least 30 seconds to 1 minute to ensure adequate time for applying cognitive strategies to misappraisal of cognitive symptoms (Craske & Barlow, 2014).

Interoceptive exposure is continued both in and outside of treatment until panic symptoms remit. Over time, the habituation of fear within an exposure session will ultimately lead to habituation across treatment, which leads to long-term remission of panic symptoms (Foa & McNally, 1996).  Occasionally, panic symptoms will return in individuals who report complete remission of panic disorder. Follow-up booster sessions reviewing the steps above is generally effective in eliminating symptoms again.

Pharmacological interventions. According to Craske & Barlow (2014), nearly half of patients with panic disorder present to psychotherapy already on medication, likely prescribed by their primary care physician. Some researchers argue that anti-anxiety medications impede the progress of CBT treatment as the individual is not able to fully experience the physiological sensations during exposure sessions, thus limiting their ability to modify maladaptive thoughts maintaining the panic symptoms. Results from large clinical trials suggest no advantage during or immediately after treatment of combining CBT and medication (Craske & Barlow, 2014). Additionally, when medication was discontinued post treatment, the CBT+ medication groups fared worse than the CBT treatment along groups, thus supporting the theory that immersion in interoceptive exposure is limited due to the use of medication. Therefore, it is suggested that medications are reserved for those who do not respond to CBT therapy alone (Kampman, Keijers, Hoogduin & Hendriks, 2002).

NOTE !!!

Most of us feel anxious from time to time. Entering an exam hall, coming across unfamiliar(unwanted) situation, been caught on call at midnight, getting into school with parents, etc., which can create anxiety in many people.

However, anxiety disorders are associated with various physical and psychological changes within the body often leading upto enormous personal, economic, and health care issues.

DISCLAIMER: After going through this,  if you think you have these symptoms/somebody around you does have ,  DON’T IMMEDIATE LABEL SELF/OTHERS,  rather consult an expert psychologist !!!
