Background: Impulsivity is one of the core features of borderline personality disorder (BPD), and is one of the first targets to be focused on in treatment. However, no valid, reliable, and economic self-report inventory is available to measure disorder-related impulsive behavior. Objective: To investigate the psychometric properties of the Impulse Scale (IS-27). Method: 27 items were selected in preliminary analyses and given, along with other self-reports, to a diagnostically heterogeneous sample (n1 = 115) and a sample of individuals with BPD (n2 = 149). Results: In a principal component analysis, a single-factor solution was favored. Internal Consistency and Guttmans split-half-coefficients are above 0.92. The IS-27 has good convergent validity and discriminates between diagnostic groups. Conclusions: The IS-27 has shown good psychometric properties and can be used to measure impulsivity as a behavioral component of BPD. Further testing is required to determine its sensitivity to change.
