Reducing the stickiness of negative memory retrieval through positive memory training in adolescents.

Background And Objectives: Individuals at risk for depression exhibit a decreased ability to disengage from negative memory retrieval during times of mental distress, partly because they have difficulty retrieving positive memories to repair sad mood. In this study, we tested whether this persistent tendency for negative memory retrieval could be reduced in adolescents through repeated practice to retrieve positive autobiographical memories, namely Positive Memory Specificity Training (PMST). Further, we examined the impact of this intervention on secondary outcomes, including depressive symptoms, emotion regulation strategies, and fear of positive emotions.

Does repeatedly reporting positive or negative emotions in daily life have an impact on the level of emotional experiences and depressive symptoms over time?

The extent to which people are aware of their emotional experiences, label them and communicate them to the outside world are considered to impact emotional experience itself and potentially people's depressive symptom levels. All of these aspects are important elements of one of the most common methods to study and measure emotions in the context of daily life, the so-called experience sampling method (ESM). A straightforward question that arises when using this method is whether participating in ESM may bring about changes in the momentary emotional self-reports of the people engaging in it, thereby effectively influencing that what it intends to measure; emotional experience over time, and whether this would relate to average levels of depressive symptoms.
