简要总结
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.
详细描述
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.

结局指标
主要结局
Change from baseline in Liebowitz Social Anxiety Scale Self-Rated (LSAS-SR)
时间窗: 4 months
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.
