“…Similarly, a dimensional approach for the diagnosis of PD has also been proposed for the 11th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-11;World Health Organization, 2018). Criterion A refers to impairments in self-related (identity and self-direction) and interpersonal (empathy and intimacy) domains of functioning that allow assessing the severity of a PD and a more specified evaluation of the core impairment (i.e., more intra-or more interpersonal) (APA, 2013;Benzi, Preti, Di Pierro, Clarkin, & Madeddu, 2019;Goth, Birkhölzer, & Schmeck, 2018a). The concept of personality functioning might be very useful for adolescent age groups as it considers fluctuations in personality (Benzi et al, 2019) and allows detecting and describing the central impairments of personality pathology during the transitional period of adolescence (Beeney et al, 2017;Benzi et al, 2019;Goth et al, 2018a).…”
