The Levenson Self-Report Psycopathy Instrument is one of two subscales of the Levenson Self-Report Psychopathy Scale (Levenson, M. R., Kiehl, K. A., & Fitzpatrick, C. M. (1995)). The 16 items primary psychopathy scale evaluates antisocial behaviors found in typical students.
The Levenson Self-Report Psycopathy Instrument (LSRPI) is one of two subscales of the Levenson Self-Report Psychopathy Scale. This subscale of the larger instrument measures the degree to which participants report affective and interpersonal characteristics that are callous, lacking in emotion, manipulative, grandiose, and glib. These are the hallmark characteristics of primary psychopathy based on Cleckley’s and Hare’s conceptualizations of the disorder. This measure was added to the Fast Track protocol in year 13 (2003) for cohort 1.
The 16 items primary psychopathy scale evaluates antisocial behaviors found in typical students. Each item is scored on a response scale of 0 to 3, where 0 = disagree strongly, 1 = disagree somewhat, 2 = agree somewhat and 3 = agree strongly. Item variable names and designations are listed in table 1. Items in bold on table one must be converted to a standardized raw score through reverse scoring. The variables which are reversed scored are C13BK10, C13BK12, C13BK14, C13BK15 and C12BK16. Once the items are reverse scored or standardized, all of the items are added to create a single measure of primary psychopathy, variable LPI13LPP1.
The LSRPI is appropriate in a setting in which time is limited. The LSRPI is commonly used as a single point measure of antisocial behavior. Conversion of reverse scores to standardized scores allows for meaningful comparison of sample groups and individuals within those groups. The summation of scores for each group allows for comparison of mean differences via t-test.
