Summary
Individuals with a history of depression can benefit from self-compassion meditation, which enhances autobiographical memory retrieval. In a study with 50 participants, those practicing self-compassion retrieved more specific memories compared to a control group engaged in coloring. Over four weeks, both groups reported increased positive and field memories, while no changes in memory remoteness were noted. Improvements in memory specificity, valence, and vantage perspective suggest that self-compassion techniques may help mitigate cognitive vulnerabilities associated with depression, warranting further exploration.
Abstract
Individuals with a history of depression have an increased risk for future episodes. This risk has been linked with impaired features of autobiographical memory retrieval that remain when depressive symptoms abate, including memory specificity, remoteness, valence, and vantage perspective. Rumination has been shown to influence these impairments and can be reduced via compassion training. We therefore investigated the effects of a self-compassion meditation on autobiographical memory retrieval in remitted depression. Baseline data were collected (n = 50) using an extended version of the Autobiographical Memory Test where participants with remitted depression retrieved specific memories from a remote time period (10 cues) and from any time period (10 cues). Valence and vantage perspective were rated. Participants were then randomly allocated to a self-compassion meditation or (control) colouring intervention group. Baseline measures were reassessed after four weeks of the intervention. Results revealed increased retrieval of specific memories in the self-compassion group in comparison to the colouring group, and an increase in positive and field memories across groups while no remoteness changes were observed. This self-compassion meditation demonstrated initial promise as an intervention to influence features of autobiographical memory retrieval in remitted depression. Improvements were shown in specificity, valence, and vantage perspective. Addressing these features with this type of intervention might reduce a cognitive vulnerability to depression and should be investigated in future studies.
