研究概览
简要总结
This study will recruit 100 participants who self-report high symptoms of social anxiety (Social phobia inventory >30). Participants will be randomly assigned to receive either one analog intervention of Imagery Rescripting (IR) or Imaginal Exposure. We will test the efficacy and mechanisms behind each interventions.
详细描述
After being informed about the study potential risks, all patients giving written informed consent will undergo screening to determine eligibility for study entry. They will be randomly assigned to two conditions (Imagery rescripting Vs. Imaginal exposure) at a 1:1 ratio. Participants will attend three ~1 hour online ZOOM sessions (pre-assessment and measurement, intervention, and post assessment and measurement).
Assessors will be blind to the treatment condition.

结局指标
主要结局
Change from baseline in the Social phobia inventory (SPIN) at the follow-up session
时间窗: Will be measured at Baseline (6,9, or 12 days before intervention), Post-intervention (immediately after the intervention) and Follow-up ( 7 days after the intervention)
The SPIN is a validated self-report instrument assessing average social phobia symptom intensity over the past week. possible scores range from 0 (not at all) to 4 (Extremly). change = (follow-up score - Baseline Score)
次要结局
- Change from Baseline to follow-up in the amount of negative and positive/neutral content details the participant provides while describing the negative imagery. The imagery will be probed using the Waterloo Image and Memories Interview (WIMI).(Will be measured at Baseline (6,9, or 12 days before intervention) and Follow-up ( 7 days after the intervention))
- Change from Baseline to follow-up in negativity of the core-beliefs that the participant link to the negative imagery provided in the WIMI.(Will be measured at Baseline (6,9, or 12 days before intervention) and Follow-up ( 7 days after the intervention))
- The Patient's Experience of Attunement and Responsiveness Scale (PEAR) measures participants' feelings of acceptance by the intervention and interview providers(Will be measured at Baseline (6,9, or 12 days before intervention), Post-intervention (immediately after the intervention) and Follow-up ( 7 days after the intervention))
- Change from Baseline in the Thought fusion inventory (TFI) at the follow-up session(Will be measured at Baseline (6,9, or 12 days before intervention), Post-intervention (immediately after the intervention) and Follow-up ( 7 days after the intervention))
- Change from Baseline in the White Bear Suppresion inventory (WBSI) at the follow-up session(Will be measured at Baseline (6,9, or 12 days before intervention), Post-intervention (immediately after the intervention) and Follow-up ( 7 days after the intervention))
- Change from Baseline in the Positive and Negative Affect Scale (PANAS) international version short form (10 items from the negative subscale only) at the follow-up session(Will be measured at Baseline (6,9, or 12 days before intervention) and Follow-up ( 7 days after the intervention))
- Sentence Completion Task (SCT). Measures participants automatic interpretation bias while being presented with 10 ambiguous social scenarios.(Will be measured at Baseline (6,9, or 12 days before intervention) and Follow-up ( 7 days after the intervention))
- The Brief core schema scale (BCSS) measures participants' self beliefs about themselves and others.(Will be measured at Baseline (6,9, or 12 days before intervention), Post-intervention (immediately after the intervention) and Follow-up ( 7 days after the intervention))
- Change across time in the Mini Social phobia inventory - revised (mini SPIN-R) from baseline to pre-treatment and from pre-treatment to follow-up.(Daily, from Baseline to follow-up (a total of 14, 17, or 20 days))
- Daily questionnaire about negative intrusive imagery in general and specific to the imagery provided in the interview.(Daily, from Baseline to follow-up (a total of 14, 17, or 20 days))
- imaginal Behavioral Approach Test (iBAT) that measures the participant's willingness to interact with pre-scripted distressing scenarios in imagination(Will be measured at Baseline (6,9, or 12 days before intervention) and Follow-up ( 7 days after the intervention))
