While NSSI is an important predictor of suicide attempts, not all youth with NSSI experience this outcome. The objective of this study is to report on the overlap between NSSI and suicidal ideation or attempt among Canadian youth self-reporting these behaviours in the general population to define a group of youth who engage in NSSI alone. This group of youth may represent a unique clinical phenotype.MethodsWe used data from 14-17 year olds (<i>N</i> = 2,576) from the 2014 Ontario Child Health Study, a province-wide, cross-sectional, epidemiologic study of child health and mental disorder. Based on their responses to questions about past year experiences of suicidal thoughts and behaviours including NSSI, 6 mutually exclusive groups were created reflecting their differing profiles of suicidal thoughts and behaviours. These groups were compared to each other on socio-demographic and symptom characteristics.ResultsA total of 9.2% of youth reported NSSI, and half of these youth endorsed NSSI alone (without suicidal ideation or attempts). Both groups had significantly more females. Compared to other groups of youth endorsing suicidal thoughts and behaviours, the NSSI alone group had lower symptoms of mental disorder in all domains except for social anxiety symptoms. They also had the lowest perceived need for help of all groups.ConclusionsAbout half of youth who self-harm do so without suicidal intent, and some for as long as 1 year during adolescence. Further prospective study of youth with NSSI alone is needed, to determine symptom stability as well as incident more risky suicidal behaviour before recommendations regarding the appropriateness of minimal medical or psychological intervention for youth who engage in this behaviour can be considered. There also are important sex differences in NSSI that deserve additional prospective study.</p>","PeriodicalId":55283,"journal":{"name":"Canadian Journal of Psychiatry-Revue Canadienne De Psychiatrie","volume":" ","pages":"7067437251337609"},"PeriodicalIF":3.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081368/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous systematic review of 10 years ago found that the evidence-base was limited to small studies, with only one including controls. This review updates the evidence using studies conducted in Canada over the last decade.MethodsA systematic search of PubMed/Medline, Embase, CINAHL, and PsycINFO for any Canadian study of outcomes following CTO placement from March 2015 to January 2025.ResultsWe identified four articles from three studies. Adding these studies to the previous search gave a total of nine articles from seven studies. None could be included in a meta-analysis. There were reductions in readmission rates and bed-days following CTO placement, while psychiatric symptom, outpatient attendance, treatment adherence participation in psychiatric services and housing all improved. In one study, perceived coercion was no greater in the CTO cases than the controls and being on an order preferable to being in hospital. However, many of the studies were small and only two included controls, of which solely one adjusted for potential confounders using either matching or adjusted analyses. The certainty of evidence was therefore rated as very low.ConclusionsThe evidence-base for the use of CTOs in Canada remains limited. This research gap contrasts with other countries that have conducted large studies using randomized or matched controls and adjusted analyses.

One hundred forty-six participants were randomly allocated to 1 of 2 groups: Ca-CBT (experimental group) or standard cognitive behavioural therapy (CBT) (control group) in a 1:1 ratio. The primary outcome, feasibility, was measured through engagement, recruitment, and participant retention. Acceptability was measured through the Verona Service Satisfaction Scale. Working Alliance Inventory was used to measure therapeutic engagement. Secondary outcomes included depression (Hospital Anxiety and Depression Scale-HADS), somatic symptoms (Bradford Somatic Inventory-BSI), and disability (WHO Disability Assessment Schedule 2.0 (WHODAS). Assessments were carried out at baseline, at the end of therapy (12 weeks from baseline), and at follow-up (36 weeks from baseline).ResultsWe were able to recruit participants within the given timeframe with excellent retention rates in both arms.

The present study aimed to shed light on these dynamics by investigating the symptoms network of CPTSD and positive symptoms of psychosis.MethodsA network analysis was performed on CPTSD and psychosis symptoms among a Canadian community sample with a history of traumatic life events (<i>n</i> = 747).

PTSD and CPTSD groups had a significantly higher severity of positive symptoms of psychosis compared to the no-disorder group. Network analysis revealed 3 distinct communities of symptoms of PTSD, disturbances in self-organization, and psychosis. Affective dysregulation served as the bridging symptom between the communities.
