Using data collected from the multisite Latin American Trans-ancestry INitiative for OCD genomics (LATINO) study, this study sought to replicate and extend previous findings regarding the clinical presentation associated with comorbid OCD and PTSD (OCD + PTSD). Differences in OCD severity, OCD symptom dimensions, OCD-related insight, avoidance, pathological doubt, and quality of life were compared across 1995 Latin American adults (<em>M</em> age = 31.54) with OCD alone (31.6%), OCD with other comorbidities (54.6%), and OCD + PTSD (13.8%), and psychiatric comorbidities were compared between participants with OCD + PTSD and OCD with other comorbidities. Replicating and extending prior research, individuals with OCD + PTSD had more severe clinical presentations across all domains, with the largest effect size found for quality of life. Consistent with previous research, these findings indicate that the presence of PTSD is associated with worse OCD clinical severity among Latin Americans, underscoring the necessity for comprehensive assessment strategies and integrated treatment approaches.</div></div>","PeriodicalId":48902,"journal":{"name":"Journal of Obsessive-Compulsive and Related Disorders","volume":"49 ","pages":"Article 101011"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147710517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the task, participants moved a cartoon mouse on a 3 × 3 grid toward a piece of cheese, with success determined by a hidden time-based contingency (trial duration ≥4 s). We analyzed behavioral indices and participants’ explicit convictions based on illusory rules determining success. Contrary to our preregistered hypotheses, patients with OCD did not form stronger superstitious beliefs than controls. However, they achieved fewer successful trials than patients with anxiety disorders. Post hoc analyses indicated that this reduced success was associated with lower exploratory behavior.

Only one reported that their most recent collaboration with clergy was harmful. Clinicians described several barriers to scrupulosity treatment, such as limited awareness of OCD and ERP among clergy, clergy accommodation of OCD symptoms, and clinicians' limited knowledge of religion. While many clinicians providing OCD treatment do not engage clergy, those who do generally find these interactions helpful. Future research should examine how treatment outcomes may be impacted by collaborations with clergy, OCD psychoeducation for clergy, religious literacy training for clinicians, and how to facilitate collaboration between experts in mental health and religion.</div></div>","PeriodicalId":48902,"journal":{"name":"Journal of Obsessive-Compulsive and Related Disorders","volume":"48 ","pages":"Article 100998"},"PeriodicalIF":1.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146187955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sample of 228 patients with a primary DSM-5 OCD diagnosis completed measures of OCD severity, OCPD traits/severity, quality of life, and mood. Results indicated that 25 % of the sample met full DSM-5 criteria for OCPD. POPS scores were positively correlated with OCD symptom severity, depression symptoms, and anhedonia and negatively with quality of life. Controlling for demographic differences, individuals with comorbid OCPD reported greater overall OCPD severity, higher levels of OCPD traits (except Emotional Overcontrol) as well as greater OCD severity but did not differ from those without OCPD on depression symptoms, anhedonia, and quality of life. Receiver Operating Characteristic (ROC) analysis revealed that a POPS Total cut score of 178 demonstrated 80 % sensitivity in detecting OCPD within this OCD sample. These results suggest that OCPD traits are common in individuals with OCD and may exacerbate OCD symptoms.

Fifty-one studies, mostly cross-sectional, with 15 072 participants met the inclusion criteria. Studies focusing specifically on general obsessions and compulsions revealed that obsessions tend to be more prevalent among individuals with ED, and there was more evidence supporting their association with ED symptoms. OCD subtypes were categorized based on the assessment scale used. The symmetry/exactness and ordering/arranging dimensions of the Yale-Brown Obsessive-Compulsive Scale; the doubting and slowness dimensions of the Maudsley Obsessive-Compulsive Inventory; the obsessing and ordering dimension of the Obsessive-Compulsive Inventory; obsessional and the impulses dimensions of the Padua Inventory, and the cleaning/washing dimension of other scales showed more notable associations with ED symptoms compared to other dimensions. Also, obsessive beliefs were found to be related to ED symptoms. The included studies demonstrated that OCD symptoms are linked to eating disorders and behaviours through both cognitive and behavioural components. Particularly, the cognitive aspect of OCD, characterized by obsessions and obsessive beliefs, may play an important role in comorbidity with ED.

Body representations are also used for movements and actions (e.g., symptom behavior). These aspects of action-oriented body representations have not been examined yet. The aim of the current study was to investigate general mental rotation and mental rotation of body versus non-body targets to capture such action-related representations. Sixty-three individuals (<em>n</em> = 35 BDD participants, and <em>n</em> = 28 mentally healthy controls [HC]) were included and performed two mental rotation tasks of non-body and body-stimuli.

Although the conclusion should be interpreted cautiously given methodological factors related to task and participant characteristics, the findings suggest that potential distortions in action-related body representations in BDD may not occur on a general body-related level.
