Background: The need to develop clinical and empirically-based tools for assessing personality development in adolescence led to the proposal of the IPOP-A (Ammaniti, Fontana, Kernberg, Clarkin, & Clarkin, 2011), a semi-structured interview for adolescents that aims to differentiate personality organization processes from characteristics that may reflect a personality disorder.
Objective and Method: This research aimed to evaluate the adaptation of the IPOP-A to the Portuguese population, attending to its diagnostic properties and its discriminant validity by comparing a clinical group with a nonclinical one. A total sample of 44 adolescents from 13 to 18 years old has taken part in this study, 22 of whom had a previous personality disorder diagnosis. The content of the interviews was transcribed and codified according to the coding manual.
Results and Conclusion: The results show that the Portuguese version of the IPOP-A presents good internal consistency values and can be considered a valid instrument to identify adolescents with a personality disorder.
