A study investigating six different versions of a computerized attention bias modification internet program in the treatment of social phobia / social anxiety disorder.
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 compared with a program that implicitly directs the users' attention towards threatening cues. Pre/post-measurements will be compared in a sample of individuals that meet diagnostic criteria of Social Anxiety Disorder. Participants will be randomized to one of three groups, receiving one of the two variants of the attention bias modification program or a control training program.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control training with words | Sham Comparator | Computerized, internet-based control training program. 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. |
|
| Control training with words + pictures | Sham Comparator | Computerized, internet-based control training program. 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. |
|
| Positive bias training with words | Active Comparator | 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. |
