Description of intervention(s) / exposure
This study will examine the effect of c-MeST in addition to usual care, and test whether it enhances treatment effects and reduces risk of depression at follow-up.

The computerised Memory Specificity Training program (c-MeST) comprises seven modules based on content from validated methods of improving autobiographical memory specificity and reducing depressive symptoms. The intervention is accessed online, is individually administered, and completely automated.
Initially, the aims, rationale, structure, and process of the intervention will be presented to participants. In each of the 7 modules (approximately taking 15-30 minutes) participants are provided with examples of specific autobiographical memories (AM). They are then provided with a series of cue words and sentences and asked to retrieve specific memories from their past relating to these cues. These include positive, neutral, and negatively-themed cue words (e.g., proud, sorrow, table), as well as prompt questions to elicit AM. Participants’ responses are fed into an algorithm which has been tuned to identify whether the participants response is a specific AM or not. Feedback is then given to help participants learn how to correctly retrieve specific AM. Participants can access the intervention for a period of 1 month, and complete modules at their own pace and convenience.

Statistical methods / analysis
Power calculation and analyses: A total sample of 128 participants will be needed. This will be sufficient to detect a moderate-sized, clinically-meaningful between-groups effect of d = .50, with .80 power and alpha level of 0.05 (two-tailed), while controlling for amount of usual care treatment (type and amount monitored at each time-point). 154 participants will be recruited at baseline to allow for 20% attrition. Analyses will be conducted on an intention-to-treat basis, with supplementary per protocol analyses. Linear mixed models analysis will be used, with group, and interaction modelled as fixed effects, and participants, time-points, and practice location modelled as random effects.

Summary
Brief summary
Current effects of treatment for depression in youth are modest. There is clear scope to enhance intervention in this critical period of early-onset depression. One way to do this is to target known cognitive vulnerabilities. This study will examine the effect of computerised memory specificity training (c-MeST) in addition to usual care, and test whether it enhances treatment effects and reduces risk of depression at follow-up. Youth aged 15-25 presenting to participating mental health service providers will be randomised to usual care + c-MeST or usual care. c-MeST involves completing a series of online modules providing personal memories with feedback to encourage more specific and detailed account of experiences.
It is hypothesised that:
• The c-MeST + usual care group will report significantly higher rates of remission of clinical and subclinical depression and lower severity of depressive symptoms at 1, 3, and 6 six-month follow-up, relative to a usual care group.
• Improvements in memory specificity at 2 weeks will predict improvements in remission rates and severity of depressive symptoms at 1, 3 months and at 6 month follow-up.
• The c-MeST + usual care group will report significant improvements on secondary outcomes of suicidal ideation, rumination, executive functioning, and problem-solving ability at 1, 3 months and six-month follow-up, relative to a usual care group.
