简要总结
The current study aims to examine the impact of booster sessions of cognitive control training (CCT) on indicators of depression vulnerability. Remitted depressed individuals (RMD) will be randomized over two groups, each receiving 10 sessions of the adaptive Paced Auditory Serial Addition Task, a well-established CCT procedure (Koster et al., 2017; Siegle et al., 2007). During and following completion of the training procedure, functioning will be monitored on a weekly basis over a period of 15 weeks. During this period, one group will be offered booster sessions based on early warning signs for possible recurrence of depression, whilst the other group will not receive booster sessions.
详细描述
Cognitive impairments are closely associated with depression and recent studies have found that these cognitive problems can persist following remission of depression. Internet-delivered cognitive control training (CCT), and the adaptive Paced Auditory Serial Addition Task (aPASAT) in particular, has shown to be an effective preventative intervention for remitted depressed individuals (RMD), where beneficial effects have been found for rumination, depressive symptomatology (Hoorelbeke & Koster, 2017), and risk for recurrence of depression (Hoorelbeke et al., 2021). At the same time, prior studies suggest significant heterogeneity in response to CCT, where RMD individuals can show strong fluctuations in functioning in the months following completion of aPASAT training. In line with this, recent findings suggest that, for individuals with high-risk profiles, initial training gains may diminish over time, resulting in recurrence of internalizing symptomatology (Hoorelbeke et al., 2022). As such, there may be merit in the use of CCT booster sessions.
Currently, it is unclear whether offering additional CCT sessions when RMD individuals are reporting increased symptomatology (i.e., adding booster sessions based on early warning signs for possible recurrence of depression) can increase the long-term effectiveness of CCT. In this study, two groups of RMD individuals will perform 10 CCT sessions, after which one group will be offered booster sessions (contingent on indicators of functioning). For this purpose, we will rely on 15 weekly mobile assessments, using the PHQ-9 questionnaire. In addition, functioning will be assessed using a more extensive assessment battery at baseline, post-training (2 weeks after baseline) and follow-up (15 weeks after baseline).
