Obsessive–compulsive tendencies, self/other perception, personality, and suicidal ideation in a non-clinical sample

Research on the risk factors for SI in adults with OC tendencies is limited, and it is still unclear whether the association between OC tendencies and SI in non-clinical individuals exists. The goal of the present study was to test the associations between OC tendencies, self/other perception, personality traits, depressive symptoms and SI among a non-clinical adult population. We investigated an Italian sample of 337 adults, who were administered a set of self-report questionnaires to assess obsessive–compulsive tendencies, depression, self/other perception, personality traits, and hopelessness. Confirmatory factor analyses (CFA) were performed. In the final model we found that personality, obsessive– compulsive factor and suicidal ideation were significantly correlated with each other: personality correlated negatively with obsessive–compulsive factor and suicidal ideation, while obsessive–compulsive factor and suicidal ideation resulted as strongly positively associated. Our results highlight the importance of assessing OC tendencies, negative self/ other perception and SI. Understanding their role and interplay will allow for the development and implementation of more advanced prevention and treatment policies.
