A Randomised Controlled Clinical Trial of Memory Specificity Training (MEST) for Depression

Not Applicable

Completed

• Conditions: Depressive Symptoms; Major Depressive Disorder

• Registration Number: NCT01882452
• Lead Sponsor: Medical Research Council

Brief Summary

Depression involves the tendency to recall overgeneral personal memories, a phenomenon which has been linked to numerous adverse psychological outcomes. The purpose of this study is to investigate whether a group-based Memory Specificity Training (MEST) programme improves outcomes in depression, and how this compares to an education and support control group. The primary aim is to examine whether MEST, which involves repeated practice retrieving specific autobiographical memories reduces depressive symptoms immediately post-treatment, and whether this is maintained 3 months after treatment. The secondary objective of this trial is to examine the role of hypothesised cognitive processes (ie., rumination, executive control, cognitive avoidance) which may underlie improvements in depression and memory.
