Treatment of Social Phobia With Cognitive Bias Modification

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether different internet-based treatment programs, consisting of cognitive bias modification, reduce symptoms of social phobia among a population diagnosed with this disorder.

Detailed Description
-----------------
Previous studies have shown that individuals with social phobia have attention biases, often focusing on aversive stimuli or avoiding aversive stimuli. Computerized training programs have been developed to implicitly direct the users attention towards a neutral, non-threatening stimuli. In this study, such a program will be provided to 128 participants that meet the diagnostic criteria for social phobia. It will be compared with a program that implicitly directs the users' attention towards threatening cues. Pre/post-measurements will be compared. Participants will be randomized to one of three groups, receiving one of the two variants of the cognitive bias modification program or a control training.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: CBM training program variant 1<br>Attention training towards positive cues using words as stimuli | Behavioral: Cognitive bias modification training program variant 1<br>* Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 1. Participant is exposed to two words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session, of one third is the neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more positive word.<br>|
| Experimental: CBM training program variant 2<br>Attention training towards positive cues using words and faces as stimuli | Behavioral: Cognitive bias modification training program variant 2<br>* Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 2. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more positive word or face.<br>|
| Experimental: CBM training program variant 3<br>Attention training towards negative using words as stimuli | Behavioral: CBM training program variant 3<br>* Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 3. Participant is exposed to two words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more negative word.<br>|
| Experimental: CBM training program variant 4<br>Attention training towards negative using words and faces | Behavioral: CBM training program variant 4<br>* Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 4. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more negative word or face.<br>|
| Experimental: Control training variant 1<br>Control training condition using words as stimuli | Behavioral: Control training variant 1<br>* Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 1. Participant is exposed to a pair of words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe follows the more positive word and the more negative word with equal frequency..<br>|
| Experimental: Control training variant 2<br>Control training condition using words and faces as stimuli | Behavioral: Control training variant 2<br>* Computerized, internet-based control training program, variant 2. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (< or >) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive.

| Change from baseline in Liebowitz Social Anxiety Scale Self-Rated (LSAS-SR) | The Liebowitz Social Anxiety Scale (LSAS) is a questionnaire by psychiatrist and researcher, Michael Liebowitz, whose objective is to assess the range of social interaction and performance situations which patients with social anxiety disorder may fear. It is commonly used to study outcomes in clinical trials. The scale features 24 items, 13 relating to performance anxiety and 11 concerning social situations. It is not intended for use as a self-reporting diagnosis. | 24 hours |
