Plain English Summary

Background and study aims
Accumulating evidence shows that a cognitive factor associated with a worsening of depressive symptoms amongst people with and without diagnoses of depression – reduced Autobiographical Memory (rAMS) – can be ameliorated by a group cognitive training protocol referred to as Memory Specificity Training (MeST). When transporting interventions such as MeST from research to routine clinical practices (RCPs), modifications are inevitable, with potentially a decrease in effectiveness, so called voltage drop. We examined the transportability of MeST to RCPs as an add-on to treatment as usual with depressed in- and out- patients.

Who can participate?
Adult people who are currently being treated in the participating Routine Clinical Practices, and who show reduced autobiographical memory specificity as assessed by the Autobiographical Memory Test.

What does the study involve?
The study involves the group training Memory Specificity Training. In this training, people train in getting better at retrieving personal memories and retrieving more details.

What are the possible benefits and risks of participating?
Participating in this study might impact the cognitive vulnerabiltiy factor, which can have a concomitant effect on depressive symptoms and related processes as rumination. No side effects or risks are known. Retrieving unpleasant autobiographical memories and noticing that people lack this skill might be experienced as inconvenient.

Where is the study run from?
This study is run from the KU Leuven. Routine Clinical Settings in Flanders can participate after which local clinicians are trained so that MeST can be offered to patients as a part of the standard routine care, after adapting MeST.

When is the study starting and how long is it expected to run for?
The study runs from 1/1/2015 to 30/12/2018.

Who is funding the study?
The study is funded by the KU Leuven Program Funding Grant PF/10/005.

Study hypothesis

Adapting the Memory Specificity Training (MeST) and training clinicians in routine clinical practices in delivering MeST will result in an increase in the skill of retrieving specific autobiographical memory.

Overgeneral autobiographical memory

Intervention

A group training protocol called Memory Specificity Training.

Session 1 of MeST focuses on psycho-education regarding memory problems linked to depression. Three main memory problems are described: reduced levels of concentration, a bias in retrieving mainly negative memories and rAMS. It is explained to participants, within a group setting, that only rAMS can be considered as a risk factor for depression and that training can remediate rAMS to some extent. After this psycho-education, two specificity exercises are conducted within the group. Exercises consist of a presented cue word after which participants are encouraged to retrieve a specific memory and as many details as possible. After each participant writes down their memory, participants help each other with becoming more specific by asking for more details. The session ends by introducing a homework assignment: to re-read the psycho-education, to write down one specific memory for each of ten (positive & neutral) words and to write down one memory of the day at the end of each day.

In Session 2, after briefly repeating the psycho-education, homework assignments are discussed. Next, some exercises are conducted together within the group wherein participants need to retrieve two memories for one cue word. Homework assignments after this session consist of writing down two memories for each of ten (neutral & positive) cue words and writing down two memories of the day each day.

Session 3 has a similar structure but the exercises now offer word pairs of two opposing valences (e.g. skilful and clumsy). The homework assignment contains two memories for each of ten words (neutral, positive but also negative) and writing down two memories of the day each day. In the fourth and last session, after evaluating the homework assignments, a psycho-education on the STOP-model is given. The aim here is that participants learn to notice when they are overgeneralizing by: signalling to themselves when they are thinking at an overgeneral level; trying to think back to the specific event that prompted the overgeneral thinking; to obtain and generate specific details about that event as much as possible; and, as a last step, try to find an opposite example. After this, some more exercises with opposing cue words are conducted

Drug names

Primary outcome measure

The ability to retrieve specific autobiographical memories was measured using the Autobiographical Memory Test (AMT) pre-intervention and post-intervention.

Secondary outcome measures

Depressive symptoms were assessed pre- and post-intervention using questionnaires chosen by the practitioners such as the Patient Health Questionnaire 9 (PHQ-9) and the Beck Depression Inventory II (BDI-II).
