Outcome Measures

Primary Outcomes (3)

  • 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.

Interventions

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.

CBM training program variant 1

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.

CBM training program variant 2

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.

CBM training program variant 3

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.

CBM training program variant 4

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..

Control training variant 1

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.
