Remission status in persistent depressive disorder following acute treatment with psychotherapy plus medication or medication alone: A 2-year naturalistic follow-up.

OBJECTIVE: Long-term benefits of acute-phase treatments for persistent depressive disorder (PDD) are unclear. Treatment guidelines disagree on the efficacy of cognitive behavioral analysis system of psychotherapy (CBASP). We examined whether acute CBASP protected against recurrence in PDD patients over two years of naturalistic follow-up. METHODS: An observational study evaluated major depressive episode (MDE) recurrences in patients completing the Research Evaluating the Value of Augmenting Medication with Psychotherapy (REVAMP) trial. Enrollees 18-75 years had PDD: current chronic MDE, recurrent MDEs with incomplete recovery, or double depression. All received open-label antidepressant medication (ADM) for 12 weeks. Non-remitters, continuing on ADM, were randomized (2:2:1) to 12 weeks of 1) CBASP, 2) brief supportive therapy (BSP), or 3) ADM alone (MEDS). Patients completing this 12-week randomized phase were offered two-year follow-up. Blinded raters assessed the primary outcome, remission status, using the Longitudinal Interval Follow-up Evaluation and Hamilton Depression Rating Scale at 3-month intervals. Analyses evaluated group differences and non-specific predictors of remission status. RESULTS: Of 323 participants entering follow-up, 203 (62.8%) met current MDE criteria during follow-up, without between-group differences: BSP: 83 (65.3%), CBASP: 85 (60.2%), MEDS: 35 (63.6%), Chi-square = 0.75; p = 0.69. Remission after acute treatment, lack of comorbid anxiety disorder, and female gender were significantly associated with lower recurrence risk. CONCLUSION: Similar to the acute phase outcomes, no group differences emerged over the 2-year follow-up, suggesting no long-term benefit of a 12-week CBASP treatment with ADM over other PDD treatments. Findings underscore the difficulty of PDD treatment and the importance of acute treatment remission. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00057551.

A systematic review and meta-analysis of the late positive potential and internalizing psychopathology.

The present study leveraged the Hierarchical Taxonomy of Psychopathology (HiTOP) framework to conduct a systematic meta-analysis to determine the association between the late positive potential (LPP) index of emotional reactivity and internalizing psychopathology. PRISMA guidelines were followed. Articles were identified through PubMed, APA PsycInfo, and Web of Science online platforms in May 2025. Included articles examined associations between the LPP to positive and/or negative stimuli and internalizing psychopathology. Risk of bias and publication bias were assessed. Results were examined for individual disorders, distress and fear subfactors, and the internalizing spectrum using two approaches: standard analyses that examined aggregate effects and hierarchical analyses that examined direct and indirect relationships. We conducted moderator analyses for sample, task design, LPP quantification, and psychopathology measurement. We included 63 studies across 5,360 participants (Mage = 19.65, SD = 11.1; 58.7% female). In standard meta-analyses, depression was associated with a smaller LPP to positive stimuli (r = -.06, 95% confidence interval [CI; -.12, -.003]). Specific phobia was associated with a larger LPP to negative stimuli (r = .21, 95% CI [.02, .37]). Distress was associated with a smaller LPP to both positive (r = -.12) and negative (r = -.11) stimuli when measured via clinical interview, and fear was associated with a larger LPP to negative stimuli (r = .10, 95% CI [.03, .16]). Hierarchical analyses indicated that the depression results were specific to the disorder, whereas the fear disorder-level results were due to the higher order fear subfactor. The LPP demonstrates discriminant relationships with distress and fear disorders and subfactors. Results were largely robust against methodological factors.
