Brief Summary

The main objective of this study is to test the effectiveness of an Internet-delivered Acceptance and Commitment Therapy (ACT) program in reducing anxiety symptoms.

Detailed Description

The purpose of this study is to test the effectiveness and level of acceptability of an Internet-delivered Acceptance and Commitment Therapy (ACT) program in reducing symptoms of anxiety. The effectiveness of the intervention will be compared with a wait-list control group using a randomized control trial (RCT) design. The participants with high / clinical levels of anxiety from the active treatment group will have the opportunity to read seven ACT modules and receive personalized feedback for their completed homework assignments.

The intervention will be delivered online and participants will have seven weeks to complete the seven modules (we might add one extra week of treatment for all participants in the event they need to compensate the treatment delays accumulated during the previous seven weeks).

GroupInterventionDescription
ACT programACT programParticipants from the active treatment group will be granted access to seven modules that are structured like chapters of a self-help book adapted for the online environment. In addition, participants from the experimental arm will be guided by an on-line therapist throughout the program duration. The on-line therapists are graduate students in clinical psychology who work under the supervision of an experienced psychotherapist. Participants will be asked to fill in a series of self-report measures to monitor their anxiety and some ACT specific processes (i.e., acceptance, mindfulness, experiential avoidance) throughout the intervention.
Primary Outcome Measures
NameTimeMethod
Changes in Anxiety Sensitivity Index (ASI)Change from Pre- to Post-Intervention (7 weeks), and Change from Post-intervention (week 7) to Follow-up (6 month post-intervention)

The ASI was designed to identify fear of somatic and cognitive symptoms of anxiety due to a belief that these symptoms may be dangerous or harmful. The scale is unidimensional and the total score rages from 0 to 64. Low scores are associated with low levels of anxiety sensitivity, while high scores are associated with high levels of anxiety sensitivity.

Secondary Outcome Measures
NameTimeMethod
Penn State Worry Questionnaire (PSWQ)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The PSWQ was designed to measure participant's level of generalized anxiety or worry. The scale is unidimensional and the total score rages from 16 to 80. Low scores are associated with low levels of worry, while high scores are associated with high levels of worry.

Social Phobia Inventory (SPIN)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The SPIN was designed to measure participant's level of social phobia. The scale is unidimensional and the total score rages from 0 to 68. Low scores are associated with low levels of social phobia, while high scores are associated with high levels of social phobia.

Yale-Brown Obsessive Compulsive Scale (YBOCS)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The YBOCS was designed to measure participant's level of obsessions and compulsions (O\&C). The scale total score rages from 0 to 40. Low scores are associated with low levels of O\&C, while high scores are associated with high levels of O\&C.

Panic Disorder Severity Scale - Self Report (PDSS-SR)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The PDSS-SR was designed to measure participant's level of panic. The scale is unidimensional and the total score rages from 0 to 28. Low scores are associated with low levels of panic, while high scores are associated with high levels of panic.

Post-Traumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual-5 (PCL-5)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The PCL-5 was designed to measure participant's level of post-traumatic stress. The scale is unidimensional and the total score rages from 0 to 80. Low scores are associated with low levels of post-traumatic stress, while high scores are associated with high levels of post-traumatic stress.

Beck Depression Inventory-II (BDI-II)Pre-intervention, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The BDI-II was designed to measure participant's level of depression. The scale is unidimensional and the total score rages from 0 to 63. Low scores are associated with low levels of depression, while high scores are associated with high levels of depression.

Overall Anxiety Severity and Impairment Scale (OASIS)Pre-intervention, week 2, week 4, week 6, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)

The OASIS was designed to measure participant's level of anxiety. The scale is unidimensional and the total score rages from 0 to 20. Low scores are associated with low levels of anxiety, while high scores are associated with high levels of anxiety.

Overall Depression Severity and Impairment Scale (ODSIS)Pre-intervention, week 2, week 4, week 6, Post-Intervention (7 weeks) and at Follow-up (6 month post-intervention)]

Each item is rated twice according to a) the importance to the overall happiness and satisfaction (0 = not at all important, 1 = important, 2 = extremely important) and b) satisfaction with the area ( -3 = very dissatisfied to +3 = very satisfied). The QOLI is a unidimensional scale with a continuous score that rages from -6 to +6, with negative score indicating a low life quality and the positive score indicating a high life quality.
