简要总结
The effect of Autobiographical Memory Specificity Training on memory specificity, positive affect and depression symptomatology
详细描述
The general objective of this study is to analyze the efficacy of an online-delivered Autobiographical Memory Specificity Training to increase memory specificity, positive affect and to reduce depression symptomatology. It will be tested in two conditions (training group vs. control group) with low-to-moderate depressive symptomatology. It is hypothesized that the training group (over control group) will increase the specificity and positive affect of autobiographical memories, and this will lead to a reduction of depressive symptomatology.

结局指标
主要结局
Autobiographical memory specificity. The Autobiographical Memory Test (AMT, Williams & Broadbent, 1986)
时间窗: Screening for eligibility criteria; Change in AMT from pre- intervention (Day 0) to post-intervention (Day 15)
AMT is the preferred measure to evaluate the degree of specificity of autobiographical memory. During the AMT application, nine verbal cue words of different valence (three positive, three negative and three neutral) will be presented to the participants to perform a recall task of specific personal memories (Dritschel et al., 2014). The specificity of the memories is scored by evaluators following specified criteria (Williams et al., 2007), and then, an overall estimate of the level of specificity of autobiographical memories can be calculated. The assessment will be conducted online, following previous works with the written version of the AMT (Takano et al., 2017). The spanish adaptation (Ros et al., 2018) has shown adequate psychometric properties in young and older populations.
