Le Corff Y, Martin-Storey A, Touchette L, Lapalme M, Forget K. (2021). Validation of a French Translation of the McLean Screening Instrument for Borderline Personality Disorder, Invariance Across Genders, and Association With Depression, Trauma Symptoms, and Substance Use Among University Students. Journal of Personality Disorders, 1-13.
The present study investigated psychometric properties of a French translation of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD; Zanarini et al., 2003) in a large sample of university students (N = 1,350). A confirmatory factor analysis supported the single-factor structure of the MSI-BPD, and its configural, metric and scalar invariance across gender was established. Internal consistency was high (tetrachoric α = .88; Ω = .88). MSI-BPD scores were significantly correlated to depressive symptoms (r = .57), trauma symptoms (r = .40), negative consequences of substance use (r = .25), and frequency of drug use (r = .11). Finally, 9.5% of the sample reached the clinical cutoff, which is similar to the pooled prevalence for BPD reported in a recent meta-analysis of university students. The present study showed that the French translation of the MSI-BPD is a psychometrically sound screening tool for BPD in both men and women.
