Description of intervention(s) / exposure
Behaviour - Memory Specificity Training
Behaviour - Education and Support

Experimental: Memory Specificity Training - Five weekly one-hour sessions of memory specificity training administered in groups of 5-8 participants.

Active Comparator: Education and Support - Five weekly one-hour sessions of an education-and-discussion supportive intervention, administered in groups of 5-8 participants.


Behaviour: Memory Specificity Training
This intervention is a manualised, structured treatment delivered over 5 x 60 minute sessions to groups of 5-8 individuals. This treatment involves repeated practice of retrieving specific autobiographical memories in response to positive, negative and neutral cue words. There is a single psychoeducation component in the first session about memory difficulties common in depression which provides the rationale for this treatment. The training is supplemented by weekly homework practice.

Behaviour: Education and Support
The education-and-support comparison condition is matched with the experimental arm for length and format (ie., 5 x 60 minute weekly sessions in groups of 5-8 individuals). Groups receive a single psychoeducation component where information about depression is provided. This is followed by non-directive support where participants are encouraged to raise different kinds of events that occur each week for discussion in the group. The sessions are supplemented by a homework diary where participants will be invited to note down an event that occurs each day, which may be positive, negative, or benign and non-emotional in nature. This material will provide the basis for discussion in the weekly group meetings.

Summary
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.
