NCT07810348

Brief Summary

Participants with Social Anxiety Disorder will be recruited from educational settings . After screening and informed consent, participants will be randomly assigned to PTC , ACG or CBT .The therapy session will be 8 session once a week, and data will be collected through psychological questionnaires in two phases at start and end of intervention.

Outcome Measures

Primary Outcomes (5)

  • Liebowitz Social Anxiety Scale-Self Report

    Liebowitz Social Anxiety Scale-Self-Report; range 0-144; higher = worse (greater social anxiety severity)

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

  • Core Belief Questionnaire (CBQ)

    Core Belief Questionnaire-Self-Trait and -Other (17 items each, 6-point Likert); range 17-102 if items are scored 1-6; higher = more strongly endorsed negative core beliefs (worse)".

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

  • Dot Probe task

    milliseconds; more positive = stronger bias toward social threat

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

  • word sentence association paradigm

    higher = more threat-relevant interpretation bias

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

  • Behavioral Avoidance Task

    SUDS 0-100; higher = more subjective distress

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

Secondary Outcomes (1)

  • beck depression inventory II

    Baseline (Day 1, before the first session) and Post-Intervention (within 7 days after the eighth session; the 8 sessions are delivered a weekly over a 8-week period

Study Arms (3)

proactive thought control

EXPERIMENTAL

The PTC (Proactive Thought Control) arm an AI-integrated, computerized intervention that trains proactive thought control, the anticipatory maintenance of a positive goal representation used to override an automatically primed negative response before it is produced (Braver, 2012). Across eight sessions, each pairing a Free Association Task (single-word cues) with a Sentence Completion Task (unfinished social-evaluative stems).

Other: AI-Proactive thought control

Cognitive Behavior Therapy

ACTIVE COMPARATOR

The CBT group served as the gold-standard comparison condition, receiving an eight-session, individually delivered cognitive-behavioral protocol adapted from the empirically supported treatment of Hope, Heimberg, and Turk (2019). To fit the study's fixed eight-session frame, it followed the manual's accelerated outline, compressing the standard sixteen-to-twenty-session course while still covering most relevant workbook chapters in order.

Other: Cognitive Behavior Therapy

Active Control Group

ACTIVE COMPARATOR

The Active Control group was a structurally and temporally matched, computerized active comparison condition that removed the intervention's active ingredient while preserving every non-specific feature. Participants completed the same two tasks (Free Association and Sentence Completion), the same cue/stem material, same three blocks of 30 trials per session (720 across eight sessions), same self-paced presentation, practice trials, on-screen appearance, and time on task, so the two conditions were equated on stimuli, dose, feedback salience, and engagement. The key difference was the omission of the proactive-thought-control contingency.

Other: Active Control

Interventions

8-session CBT protocol ( Hope, Heimberg \& Turk, 2019 manual) The CBT arm received an eight-session protocol moving from psychoeducation and the three-component model of social anxiety with an individualized Fear and Avoidance Hierarchy (Sessions 1-2), through cognitive restructuring using disputing questions from automatic thought to rational response (Sessions 3-4), to repeated graded exposure using role-plays, distress ratings, and added cognitive tools, with the final session offering core-belief work and setting post-treatment maintenance goals (Sessions 5-8)

Cognitive Behavior Therapy

The two paired tasks Free Association Task (FAT) and Sentence Completion Task (SCT) form the core of the AI-integrated Proactive Thought Control (PTC) program. FAT shows a social-threat word and the participant types the first associated word, training proactive control at the lexical level; SCT then gives unfinished social-evaluative stems to complete with a benign word, extending the override to the propositional level. Both run three blocks of thirty self-paced trials per session (720 over two weeks), so every threat trial forces a positive, cue-relevant representation that overrides a primed negative associate before advancing. AI integration relies on real-time validation: SiEBERT scores sentiment and MiniLM embedding confirm semantic relevance, enforcing a positive, cue-relevant construal each trial. Feedback reinforces this accepted responses earn points, rejected one prompt revision, and the threshold relaxes after four failures and pass after eight.

proactive thought control

Participants did the same two tasks as the experimental group. The Free Association Task and the Sentence Completion Task , matched on stimuli, format, and time. The key difference was that the control removed the core training element: responses were not checked for meaning against the cue, and about half of the negative answers were accepted without correction, so the link between a threat cue and forcing a positive response was broken. In short, the control group did the same tasks and got the same exposure, but without the active thinking-training component.
