NCT05462184

Brief Summary

Objective: Panic disorder is one of the most prevalent anxiety disorders and with the greatest impact on the functionality of patients. Knowing variables that influence the therapies outcome can improve the results of the interventions and reduce the socio-health cost. The current study examined possible predictors and moderators of outcome in cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT). Method: Eighty patients with diagnostic of panic disorder received 12 group sessions of CBT or ACT and were assessed with several measures at baseline, 12 weeks post-treatment and 24 weeks post-treatment.

Outcome Measures

Primary Outcomes (3)

  • Change from Baseline level of Severity of Panic Disorder at 12 weeks and 24 weeks post-treatment.

    It is evaluated through the Panic Disorder Severity Scale-Self Report. It is a self-administered scale whose objective is to determine the level of severity of panic disorder in the last month. It is composed of 7 items, which explore: (1) frequency of panic attacks, (2) distress provoked by panic attacks, (3) anticipatory anxiety, (4) agoraphobic fear and avoidance, (5) fear and/or avoidance of situations, (6) impairment and/or interference in work activity, and (7) impairment and/or interference in social activity. The patient answers using a Likert-type scale from 0 to 4, with 0 being the minimum and 4 the maximum severity of symptoms. It provides a profile of the intensity and presence of symptoms in the last month.

    Baseline, 12 weeks post-treatment and 24 weeks post-treatment.

  • Change from Baseline degree of Fear of Physical Symptoms at 12 weeks and 24 weeks post-treatment.

    It is evaluated through the Body Sensations Questionnaire. It is a self-administered questionnaire composed of 17 items plus 1 final open-ended item. The subject responds to each item according to a 5-point Likert-type scale. This questionnaire evaluates the degree of fear or concern generated by each of the physical symptoms that occur during panic attacks. The final score is obtained by calculating the mean of the 17 items. A high score is indicative of a great fear of the physical symptoms.

    Baseline, 12 weeks post-treatment and 24 weeks post-treatment.

  • Change from Baseline frequency of Agoraphobic Cognitions at 12 weeks and 24 weeks post-treatment.

    It is evaluated through the Agoraphobic Cognitions Questionnaire. It is a self-administered questionnaire composed of 14 items (plus a final open-ended item) on a 5-point Likert-type scale. It evaluates the frequency with which the patient has catastrophic thoughts about the negative consequences of experiencing anxiety when anxious. It is composed of two subscales: catastrophic thoughts about physical consequences of anxiety (heart attack, tumor, etc.) and catastrophic thoughts about social and behavioral consequences (making a fool of oneself, going crazy, etc.). An overall score is obtained by calculating the mean of the total items and the scores on the two subscales: physical level and social-behavioral level.

    Baseline, 12 weeks post-treatment and 24 weeks post-treatment.

Study Arms (2)

Cognitive-Behavioral Therapy (CBT)

ACTIVE COMPARATOR

CBT followed Craske \& Barlow´s (2007) manual, which contains a session-by-session description treatment of panic disorder with CBT. The treatment included the following components: (a) psychoeducation about the nature of anxiety and panic, (b) diaphragmatic breathing training, (c) identification and correction of maladaptive thoughts about anxiety and its consequences, (d) exposure to interoceptive sensations, and (e) exposure to feared situations.

Behavioral: Cognitive-Behavioral Therapy (CBT)

Acceptance and Commitment Therapy (ACT)

EXPERIMENTAL

ACT was conducted following Eifert \& Forsyth´s (2005) manual, which contains a session-by-session description of the application of ACT to anxiety disorders. In the current study, exercises were adapted to the panic disorder treatment. The treatment included the following components: (a) acceptance of internal experiences, (b) cognitive defusion, (c) work with the "self as context", (d) contact with the present moment, (e) work with life values, and values, and (f) commitment to action.

Behavioral: Acceptance and Commitment Therapy (ACT)
