AbstractThe last decade was extremely dynamic in the field of personality disorder. The extensive research has resulted with significant changes in conceptualization and assessment of personality psychopathology. DSM 5 has introduced a hybrid diagnostic model of personality disorders, which leads toward implementing dimensional instead of categorical approach to personality disorders. There are many questionnaires aimed to measure dimensions of personality psychopathology. However, they contain a large number of items, which may present a methodological problem in conducting research on large samples. Hence, the aim of this study is to present development of a short questionnaire aimed to measure main dimensions of personality psychopathology. The questionnaire, named Dimensional Assessment of Personality Traits Questionnaire (DAPTQ), contains 62 items distributed into 5 main scales; Negative Emotionality, Detachment, Compulsivity, Psychoticism and Antagonism, and two additional scales Grandiosity and Attention Seeking. Study was conducted on the sample of 456 high school students from Osijek and Koprivnica. The DAPTQ, YPI, LEXI - 70 and Ryff Scales of Psychological Well-Being were administered. Results indicate good psychometric properties, namely content, construct and convergent validity and reliability, of all scales of the DAPTQ. This paper discusses some measurement issues concerning personality psychopathology in adolescents' population and the ways in which they could be overcome.
