This study examined problematic anger and its longitudinal associations with marital dysfunction outcomes among 3456 U.S. service member–spouse dyads enrolled in the Millennium Cohort Program. Service members completed a self-report measure of problematic anger at Time 1 (2014–2016); spouses completed self-report assessments of intimate partner violence (IPV), marital quality, marital dissolution, relationship trust, and parenting alliance at Time 2 (2019–2021). Logistic regressions were conducted to examine associations between service member problematic anger and marital dysfunction outcomes using hierarchical adjustment for categories of covariates. Service member problematic anger was associated with IPV experience, low martial quality, marital dissolution, and low relationship trust among spouses after adjusting for demographic characteristics and military contextual variables. However, after adjusting for mental health variables, IPV was the only marital dysfunction outcome associated with service member problematic anger. The association between problematic anger and IPV remained after adjusting for adverse childhood experiences in the final model. Results suggest that mental health conditions, in general, may contribute to marital dysfunction in military couples, but problematic anger appears to be particularly crucial in predicting IPV.

Primary endpoint was proportion with Patient Global Impression of Improvement (PGI-I) score &lt;2 at week 12 (W12). Secondary endpoints included MDD severity, MDD symptoms, and quality of life (QoL).</div></div><div><h3>Results</h3><div>Qualitative survey responses refined the quantitative study design. Quantitative study enrolled 352 receiving SOC and 151 receiving vortioxetine. At W12, proportions with PGI-I scores &lt;2 were similar (vortioxetine vs SOC: 4.5% vs 1.8%; <em>P</em> = 0.830). Mean PGI-I scores were similar at W12 (vortioxetine vs SOC: 3.5 vs 3.6; <em>P</em> = 0.831) and lower with vortioxetine at W24 (vortioxetine vs SOC: 3.0 vs 3.4; <em>P</em> &lt; 0.001). Remission rates at W24 were higher with vortioxetine (11.4%) vs SOC (2.5%; <em>P</em> &lt; 0.001). Feelings of anhedonia were significantly less frequent with vortioxetine (<em>P</em> = 0.005).</div></div><div><h3>Limitations</h3><div>Self-reported data may introduce recall bias. PLM users may have higher health literacy than the general population.</div></div><div><h3>Conclusions</h3><div>Although primary endpoint was not met, long-term vortioxetine was associated with improved global impression, QoL and life satisfaction, and a higher rate of remission, which can guide clinical decisions and empower patients.</div></div>","PeriodicalId":52768,"journal":{"name":"Journal of Affective Disorders Reports","volume":"24 ","pages":"Article 101019"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146190161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
