Little is known about the course of grief-related psychopathology in the long term. Hence, we examined their latent trajectories, overlap, and predictors to enhance our understanding of differential long-term responses to violent loss. MH17-bereaved people (<em>N</em> = 299) completed annual self-report measures from one to nine years post-loss. Prolonged grief (PG), posttraumatic stress (PTS), and major depression (MD) symptom trajectories were identified using latent class growth modeling. Overlap in trajectory membership was examined using frequencies. Predictors of trajectory membership were examined using multinomial regression analyses. Four PG symptom trajectories emerged: low (41.0 %), moderate decreasing (34.2 %), high (13.5 %), and recovered (11.3 %). Four PTS symptom trajectories emerged: low (56.2 %), recovered (19.6 %), moderate increasing (17.6 %), and high (6.6 %). Four MD symptom trajectories emerged: low (55.7 %), moderate (19.6 %), moderate decreasing (15.1 %), and high (9.5 %). The findings indicate that if people report psychopathology, this often entails PGD by itself, and sometimes in combination with PTSD and MDD, yet rarely PTSD or MDD by itself. Around one in 20 people was assigned to all three high symptom trajectories. Different predictors were found across disorders. To conclude, most MH17-bereaved people reported low grief-related psychopathology, yet one in six reported high grief-related psychopathology levels (i.e., at least probable PGD, PTSD, or MDD) nearly a decade later. There is no indication of a delayed onset of grief-related psychopathology.</div></div>","PeriodicalId":48390,"journal":{"name":"Journal of Anxiety Disorders","volume":"114 ","pages":"Article 103036"},"PeriodicalIF":4.8,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study compared both types of patient reports of improvement during cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD). We also examined process-level predictors of improvement assessed using both methods. Participants were 254 adult survivors of interpersonal violence receiving CPT. Patients' global reports of improvement in each domain (PTSD symptoms, relationships, health concerns, sexual functioning, school/work performance, and life satisfaction), each rated on a Likert scale via the Treatment Outcome Questionnaire, were significantly correlated with the corresponding standardized measure of improvement in the same domain, with most effect sizes in the small-to-medium range. Patients' perceptions of the therapy (helpfulness, likability) significantly predicted both global ratings and standardized measures of improvement, while patients' perceptions of the therapeutic relationship, patients' perceptions of barriers to therapy attendance, and objective indices of attendance did not predict improvement. Results highlight the importance of patients' experiences with treatment and suggest that assessing patients' global ratings of their improvement during treatment provides distinct information from standardized measures of improvement, and both are important to include when measuring therapeutic change.</div></div>","PeriodicalId":48390,"journal":{"name":"Journal of Anxiety Disorders","volume":"113 ","pages":"Article 103027"},"PeriodicalIF":4.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was designed to examine the prevalence of chronic pain conditions (i.e., migraines, back problems, arthritis) across PTSD courses (i.e., no PTSD, remitted, new onset, persistent/recurrent) and examine the association between PTSD course and the presence and onset of chronic pain conditions in a population-representative sample of Canadian military members. Methods: Cross-tabulations and logistic regressions were conducted on data (n = 2941) from the 2002 Canadian Community Health Survey Mental Health and Well-being Canadian Forces Supplement and the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey. Results: The prevalence of chronic pain conditions across PTSD courses ranged from 8 % to 61 %, with no PTSD consistently having the lowest prevalence. After adjusting for covariates, respondents with new onset PTSD had elevated odds of back problems (AOR=1.43, 95 % CI [1.10–1.90], <em>p</em> &lt; .05), arthritis (AOR=1.46, 95 % CI [1.06–2.00], <em>p</em> &lt; .05), and a new onset chronic pain condition more broadly (AOR=1.66, 95 % CI [1.15–2.39], <em>p</em> &lt; .01), compared to those with no PTSD.
