However, the current evidence on the interplay between accommodation behaviour (AB) and relationships is contradictory, partly because studies usually consider either the patient or the relative. The present study addresses this gap by examining the association between AB and various relationship aspects in 50 dyads, consisting of 25 patients with obsessive-compulsive disorder (OCD) or 25 patients with major depression (MDD) and their respective close others. After the dyads recalled a shared disorder-specific emotional experience, they responded to various questionnaires assessing family accommodation, OCD symptoms, depression, relationship satisfaction, subjective closeness, and conflict frequency based on an individually described relationship context. The results of the actor-partner interdependence models point to similarities and disorder-specific differences. For both groups, AB represents a challenge in the relationship. Although AB is associated with more frequent conflict, lower subjective closeness, and lower relationship satisfaction in dyads with OCD and close others of MDD, patients with MDD are more likely to experience AB as supportive. This suggests differences in the functionality of AB across various disorders, with potential disorder-maintaining effects in both OCD and MDD. Clinically, the results highlight the importance of interventions targeting interpersonal dynamics, such as family therapy and psychoeducation, to balance support while reducing symptom-maintaining behaviours. Future research should explore tailored interventions to optimize relationship functioning while minimizing the negative effects of AB.</div></div>","PeriodicalId":48902,"journal":{"name":"Journal of Obsessive-Compulsive and Related Disorders","volume":"45 ","pages":"Article 100950"},"PeriodicalIF":1.9,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research investigated social network structure (size and frequency of contact), social isolation and loneliness in relation to hoarding disorder, accounting for depression. Participants (<em>N =</em> 158) completed online questionnaires including measures of hoarding severity, social network structure, loneliness, conditions and functioning in the home, and depression. Hoarding symptom severity was negatively correlated with social network size and strength of relationship with neighbours while controlling for depression. Loneliness, however, was better predicted by depression rather than hoarding. We also compared participants who met criteria for a diagnosis of hoarding disorder (<em>n</em> = 57) and 60 healthy controls, controlling for both age and depression. People with hoarding disorder had significantly weaker family networks and stronger feelings of loneliness. Depression, but not hoarding symptoms, correlated with risk of social isolation. Among participants with hoarding, social network size was negatively correlated with functional interference (activities of daily living) and conditions in the home. Our findings stress the need for addressing social functioning when treating hoarding. Depression, integrally related to hoarding and social functioning, also needs to be considered.</div></div>","PeriodicalId":48902,"journal":{"name":"Journal of Obsessive-Compulsive and Related Disorders","volume":"45 ","pages":"Article 100949"},"PeriodicalIF":1.9,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we examined SoA in OCD using a symptom-provoking virtual reality (VR) task. Twenty individuals with OCD and 23 healthy controls had to turn off a virtual stove using an embodiable virtual hand under four experimental conditions. These conditions differed with respect to whether the virtual hand accurately reflected the participant's real hand movements or was visually manipulated, and whether the stove actually turned off or remained on. Subjective ratings of SoA, certainty and anxiety were recorded. Furthermore, repeated checking was assessed in a second block. Across conditions, individuals with OCD exhibited a significantly lower SoA, which was also more sensitive to experimental manipulation. Moreover, a lower SoA was significantly associated with increased levels of incompleteness and inflated responsibility attitudes. Our findings suggest that incompleteness, inflated responsibility and a lower SoA may mutually reinforce each other in a vicious cycle, contributing to the maintenance and exacerbation of OCD symptoms.</div></div>","PeriodicalId":48902,"journal":{"name":"Journal of Obsessive-Compulsive and Related Disorders","volume":"45 ","pages":"Article 100940"},"PeriodicalIF":1.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
