Brief reportBehavioral activation treatment for major depression: A randomized trial of the efficacy of augmentation with cognitive control training
Section snippets
Participant enrollment and randomization
Participants were recruited through advertisements and referrals from an outpatient clinic and were required to be between ages 18 and 65 and have a primary psychiatric diagnosis of MDD. Exclusion Criteria included a history of psychotic, bipolar, or neurological disorder or alcohol/substance dependence in the past 6 months; current use of modafinil, or antipsychotic or stimulant medications; or use of an antidepressant or anxiolytic medication if not taken at a stable dose for at least 8 weeks
Treatment outcome
Means and standard deviations for primary and secondary outcome measures are presented in Table 2 for the both the ITT and completer sample. BDI, MADRS, and RRS scores all decreased significantly over time, reflecting large effect sizes (all ηp2 >.3). However, for each of these measures, the interaction between time and treatment condition was not significant, and all treatment by time effect sizes fell in the small range for ITT and completer analyses (see Table 2; all ηp2<.07). Results of the
Discussion
This study tested whether CCT, a neurocognitive intervention previously shown to reduce depression symptoms, enhanced the effects of a 4-session behavioral activation therapy when compared to a control condition. No enhancement was observed on primary and secondary outcomes; both treatment groups demonstrated similar significant improvements in depression symptom severity and rumination, reflecting a large within-group effect size. This poses a contrast to studies in which CCT was shown to be
Conclusion
Our results suggest that weekly CCT does not add clinical benefit to a four-session BATD treatment, and was not associated with unique change in rumination. These findings indicate that the effects of CCT may not be as robust as previous studies have suggested, consistent with a recent re-analysis of the most comprehensive CCT study in clinically depressed patients (Siegle et al., 2014) suggesting that CCT may benefit a select group of patients who are able to allocate sufficient attentional

2022, Behavior TherapyCitation Excerpt :Ethnic/racial information by subgroup is summarized in Table 2. Two studies (i.e., Dahne, Lejuez et al., 2019; Moshier & Otto, 2017) reported demographic information in which participants had to provide race (e.g., White, Black, or Asian) and ethnicity (e.g., Latinx or NLW). Because participants who identified as NLWs may have also identified as Latinx, it may not be possible to calculate participation rates accurately.
Individual differences associated with treatment adherence and transfer effects following gamified web-based cognitive control training for repetitive negative thinking
2022, Internet InterventionsCitation Excerpt :Building on these User Profiles, which as a first step have shown merit in predicting change in cognitive- and emotional outcomes over time in the context of web-based aPASAT training, future studies could work towards a more tailored training approach. This requires further investigation of individual differences in optimal training administration, among which level of training intensity, use of booster sessions, and possibilities for augmentation of CCT (e.g., Brunoni et al., 2014; Moshier and Otto, 2017; Segrave et al., 2014; Van den Bergh et al., 2020; Vanderhasselt et al., 2015). In addition, given that the current User Profiles are mostly based on trait measures, it would be interesting for future studies to extend this approach investigating the temporal dynamics between the constructs which emerged as key determinants of User Profile (e.g., relying on idiographic vector autoregressive network models), further evolving towards a personalized medicine approach.
Cognitive control training for urgency: A pilot randomized controlled trial in an acute clinical sample
2021, Behaviour Research and TherapyCitation Excerpt :Although not hypothesized, the lack of change in urgency is consistent with recent studies that report an improvement in cognitive task performance without a corresponding change in symptoms or psychological traits, including studies utilizing the PASAT (Van den Bergh et al., 2020; Vanderhasselt et al., 2021) or inhibitory control tasks (Bos et al., 2019). Given that participants receiving training were also receiving intensive psychiatric treatment, these findings are also consistent with some investigations reporting no additive effect of cognitive training interventions in treatment settings (Moshier & Otto, 2017; Van den Bergh et al., 2020). Future studies that seek to develop interventions for urgency in acute psychiatric settings may benefit from testing meta-cognitive interventions that might circumvent weaknesses in cognitive control (e.g., Javaras, Williams, & Baskin-Sommers, 2019).
