Proactive Thought Control for Social Anxiety Relief

The registry criteria, word for word

What the trial wants to find out

This study examines whether a proactive thought control intervention can reduce negative core beliefs, cognitive biases, and anxiety symptoms in university students with social anxiety. Participants with elevated social anxiety (screened via the Liebowitz Social Anxiety Scale) are randomly assigned to either a proactive thought control group or a reactive control group. Both groups complete two computerized tasks - a Free Association Task and a Sentence Completion Task - across 180 trials. The proactive group is trained to generate only positive or neutral associations to socially threatening cues and receives real-time AI-powered sentiment feedback, while the reactive group responds freely without sentiment-based guidance. Outcomes including negative core beliefs, interpretation bias, attentional bias, state anxiety, and trait anxiety are assessed before and after the intervention using standardized measures (CBQ, WSAP, Dot Probe Task, STAI). The study uses a parallel-group randomized controlled trial design with repeated measures and aims to establish preliminary effect size estimates for future, larger-scale trials.

The 2 groups in the trial

• Proactive Thought ControlTreatment being tested

  Participants in this arm completed a modified Free Association Task (FAT) and Sentence Completion Task (SCT) across 180 trials (6 blocks of 30). They were instructed to generate only positive or neutral single-word responses to socially threatening cues and could not advance within a trial until doing so. Real-time AI-powered sentiment feedback (DistilBERT) reinforced positive/neutral responses with "+2 Score" and corrective guidance for negative responses. A gamified points system sustained engagement. Pre- and post-assessments included the CBQ, STAI, WSAP, and Dot Probe Task.

  Treatment: Proactive Thought Conrol

• Reactive Thought ControlExisting treatment, for comparison

  Participants in this arm completed the same Free Association Task (FAT) and Sentence Completion Task (SCT) across 180 trials (6 blocks of 30) as the experimental group, but responded freely without any restriction on response valence. They received only neutral quality-based feedback (e.g., for repeated, misspelled, or invalid entries) with no sentiment-based reinforcement or corrective guidance. This active sham condition controlled for task engagement, the Hawthorne effect, and demand characteristics. Pre- and post-assessments were identical to those of the experimental arm.
