Correlates of self-harm in university students: A cross-sectional study

Objective: To determine the prevalence of university students who have ever engaged in self-harm and to examine its correlates. Frequency of thinking about self-harm was explored as a secondary outcome. Participants: Students at Western University in London, Ontario, Canada. Methods: This cross-sectional study was completed via an online questionnaire. Logistic regressions assessed the influence of sociodemographic and behavioral factors associated with lifetime self-harm and thoughts about self-harm. Results: The sample consisted of 2626 university students. Almost 25% engaged in self-harm in their lifetime and close to 33% have thought about harming themselves. A non-straight sexual orientation, marijuana use, prescription drugs not prescribed, and mental health problems increased the risk of both outcomes. Females were over two times more likely to engage in self-harm than males. Conclusion: This study provides evidence that is needed for developing effective interventions to reduce the risk of self-harm by targeting university students who are most at-risk.

Psychological pain: A moderating factor between personality psychopathology and self-harm

Self-harm and personality psychopathology have been linked, with the most robust correlations existing between negative affectivity and self-harm. Psychological pain, an emotionally-based aversive feeling, has been linked to self-harm. Considering the connection between personality psychopathology and self-harm, psychological pain may enhance self-harm risk. Participants: Analyses were conducted on 525 undergraduate students in the Spring and Fall semesters of 2019. Methods/Results: Correlation analyses indicated that self-harm was moderately correlated with Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. Additionally, self-harm was correlated with psychological pain. When examining if psychological pain moderates the relation between personality psychopathology and self-harm, results were mixed. In the cases of Disinhibition and Psychoticism, psychological pain enhanced self-harm. There was no moderating effect on the relations with Negative Affectivity, Detachment, or Antagonism. Conclusions: These findings support the role of psychological pain in self-harm outcomes for those experiencing personality psychopathology; however, this varies depending on the maladaptive traits.

Clinical assessment of non-suicidal self-injury: A systematic review of instruments

There has been an increase in the number of assessment instruments for non-suicidal self-injury (NSSI). However, previous reviews are inconsistent and do not provide a comprehensive psychometric assessment of the instruments. This study aimed to systematically assess and compare the psychometric properties of clinically relevant instruments to measure NSSI in any population. Through a systematic review guided by COSMIN and PRISMA, two searches were conducted in English and Spanish in February 2020 in 13 databases including grey literature. Of the 7,813 initial records, 152 validations were extracted. From these, 83 instruments (22 versions or adaptations) were excluded for not measuring NSSI, having no potential clinical utility or not including psychometric properties. Finally, 26 (22 versions, 35 adaptations and 19 creations) instruments measuring NSSI were included. Predominantly, the studies were North American self-reports in English for community adolescents, adaptations or versions emanating from a small number of instruments. Twenty-six indicators were categorized to assess NSSI. The most frequent instruments are structured interviews, and their indicators were related to NSSI function and topography. Evidence of validity and reliability was positive but limited. Despite the high number of instruments and diversity of evaluations, we found no instrument with sufficient evidence for clinical assessment. Findings broadly overview NSSI assessment instruments' current use and future improvement in clinical and research settings.
