研究概览
简要总结
The purpose of this study is to examine the efficacy of a guided imagery paradigm for reducing negative ways of thinking about the self. There will be at least 60 participants enrolled at the University of Texas at Austin. Participants will be randomly selected to receive one of two types of trainings, each over the course of two weeks. Participants will undergo the training exercises at home. The training exercises will help them to think differently about themselves.
Participants will be able to determine if they are eligible, and then participate, by filling out a screening questionnaire online.
详细描述
This study uses a randomized controlled trial to compare two types of guided imagery. One intervention is an active intervention; the other is intended to be inert. These interventions were developed based on extensive research indicating the efficacy of using imagery in depression, and a perceived lack of treatments targeting biased self-referential processing.
This protocol aims to develop a novel intervention which can be used on its own or as an adjunct to existing treatments. Common treatments for Major Depressive Disorder (MDD) are diffuse; this paradigm instead aims to specifically target negative self-schema, a part of the cognitive model of MDD. This study focuses on participants with elevated depressive symptoms.

结局指标
主要结局
Change in response on the Self-Referent Encoding Task (SRET)
时间窗: Participants will complete the SRET at baseline, after one week, and after two weeks. Change will be assessed primarily as SRET at two weeks MINUS SRET at baseline.
The SRET is a task that asks participants to categorize words as self-referential or not. Its outcomes are focused on behavioral response and reaction time. We have shown that it has good test-retest reliability over the course of one week.
次要结局
- Depressive Symptomatology(Participants will complete measures of depressive symptoms at baseline, after one week, and after two weeks.)
