简要总结
The overall goal of the current study is to develop and evaluate a computerized interpretation bias modification (IBM) training for treating social anxiety disorder (SAD). A key focus is placed on enhancing accessibility and efficacy of IBM for SAD by delivering it through a mobile platform, with three specific aims outlined.
First, the current study aims to examine the efficacy of the IBM training in reducing social anxiety symptoms by comparing the pre-, post-, and follow-up assessments of the IBM group with a control group.
Second, the current study aims to examine the effect of IBM on reducing participants' daily social anxiety symptoms using daily diary methodology.
Third, the investigators also aim to evaluate the feasibility and acceptability of the IBM training. The investigators expect that at least 70% of participants will complete 4 or more of the six training sessions.

研究组 & 干预措施
Cognitive Bias Modification for Interpretation Bias (CBM-I)
CBM-I is designed to modify negative interpretation bias, a core cognitive characteristic of social anxiety disorder. During the training, participants will complete sentence fragments by filling in missing letters, guiding them to interpret ambiguous social scenarios in a benign way. Participants will complete the training three times per week for two weeks.
干预措施: Interpretation Bias Modification Training (Behavioral)
Stress Management Psychoeducation (SMP) Group
The Stress Management Psychoeducation (SMP) group will also receive a cognitive training intervention involving the completion of sentence fragments by filling in missing letters. However, the training content will focus on stress management strategies, such as relaxation techniques and organizational skills, rather than interpretation bias modification. Participants in the SMP group will also complete the training three times per week for two weeks.
干预措施: Stress Management Psychoeducation (Behavioral)
结局指标
主要结局
Brief Fear of Negative Evaluation (BFNE)
时间窗: Pre-training (baseline); Post-training (approximately 1-2 days after completion of the 2-week intervention); 2-week follow-up (2 weeks after completion of the 2-week intervention)
The BFNE is a 12-item questionnaire, evaluating the level of apprehension and distress about expected negative evaluation. The BFNE was used to assess the cognitive symptoms of social anxiety disorder.
Liebowitz Social Anxiety Scale- Self-report Version (LSAS-SR)
时间窗: Pre-training (baseline); Post-training (approximately 1-2 days after completion of the 2-week intervention); 2-week follow-up (2 weeks after completion of the 2-week intervention)
The LSAS-SR is a 24-item scale that assesses the severity of social anxiety symptoms across two subscales: the level of anxiety (emotional reaction) and the level of avoidance (behavioral reaction). In the current study, the two subscales will be analyzed separately to evaluate the effects of the intervention on the emotional and behavioral symptoms of social anxiety.
Diagnostic Interview for Anxiety, Mood, and OCD and Related Neuropsychiatric Disorders (DIAMOND)
时间窗: Pre-training (baseline); 2-week follow-up (2 weeks after completion of the 2-week intervention)
DIAMOND is a semi-structured diagnostic interview to assess DSM-5 psychiatric disorders and has demonstrated good reliability and validity. For the current study, only the social anxiety disorder module was administered at pre-training and follow-up assessments.
次要结局
- Treatment Acceptability Questionnaire (TAQ)(2-week follow-up (2 weeks after completion of the 2-week intervention))
- Word Sentence Association Paradigm (WSAP)(Pre-training (baseline); Post-training (approximately 1-2 days after completion of the 2-week intervention); 2-week follow-up (2 weeks after completion of the 2-week intervention))
- Daily Diary(2 weeks of training period)
- Credibility and Expectancy Questionnaire (CEQ)(After the 1st training session)
