Treatment of Social Phobia With Cognitive Bias Modification

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.

Conditions

• Social Phobia

Interventions

BEHAVIORAL

Cognitive bias modification training program variant 1

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.

BEHAVIORAL

Cognitive bias modification training program variant 2

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.

BEHAVIORAL

CBM training program variant 3

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.

BEHAVIORAL

CBM training program variant 4

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.

BEHAVIORAL

Control training variant 1

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..

BEHAVIORAL

Control training variant 2

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. The probe follows the more positive stimulus and the more negative stimulus with equal frequency.
