The aim of this study was to evaluate the psychometric properties of the Antisocial Process Screening Device (APSD; Frick & Hare, 2002) to be used with non-clinical Turkish samples. APSD is a 20-item scale that evaluates antisocial behaviors and the presence of psychopathic traits in children between 6-13 years of age. Study 1 was designed to check the internal consistency and test-retest and inter-rater reliabilities. Despite satisfactory test-retest and inter-rater reliability coefficients, the Cronbach alpha coefficients of the Callous Unemotional (CU) dimension were very low in all the three forms (parent, teacher, and combined). Study 2 was designed to check the internal consistency after conducting the revisions and also validity analyses, mainly by using the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997). Consequently, the Turkish version of APSD showed reliable and valid results to evaluate the psychopathic traits and antisocial behaviors of the children between 8-11 years of age in the non-clinical Turkish sample.
