The Hierarchical Structure and Construct Validity of the PID‐5 Trait Measure in Adolescence

Abstract

The DSM-5 may be the first edition that enables a developmental perspective on personality disorders because of its proposal to include a trait assessment in the Axis II section. The current study explores the reliability, structure, and construct validity of the Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012) in adolescents, a measure that assesses the proposed DSM-5 traits. A community sample of Flemish adolescents (N = 434; 44.7% male) provided self-reports on the PID-5 and the Dimensional Personality Symptom Itempool (DIPSI; De Clercq, De Fruyt, Van Leeuwen, & Mervielde, 2006). Results indicate an acceptable reliability for the majority of the PID-5 facets and a tendency toward structural convergence of the adolescent PID-5 structure with the adult proposal. Convergent validity with age-specific facets of personality pathology was generally supported, but discriminant validity appeared to be low. Beyond the findings that support the applicability of the PID-5 in adolescents, developmental issues may be responsible for specific differences in the adolescent PID-5 structure, the rather poor discriminant validity of the PID-5, and the lower reliability of a small number of PID-5 facets. These results indicate that further research on the validity of the PID-5 in younger age groups is required.

Estudo das Propriedades Psicométricas - Formas Longa, Reduzida e Breve - da Versão Portuguesa do Inventário da Personalidade para o DSM-5 (PID-5)

“…As facetas Suspeição e Irresponsabilidade revelaram consistências internas tendencialmente baixas. Este resultado foi também encontrado noutros estudos (Al-Dajani et al, 2016;De Clercq et al, 2014;Roskan et al, 2015), o que indica que serão possivelmente medidas menos fiáveis do que as restantes escalas do instrumento.…”

“…O PID-5 foi já traduzido e adaptado para Italiano (Fossati, Krueger, Markon, Borroni, & Maffei, 2013), Holândes (De Fruyt et al, 2013;De Clercq et al, 2014), Alemão (Zimmermann et al, 2014), Francês (Roskam et al, 2015), Dinamarquês (Bach, Maples-Keller, Bo, & Simonsen, 2016) e Arábe (Al-Attiyah, Megreya, Alrashidi, Dominguez-Lara, & Al-Sheerawi, 2017). A investigação realizada nos vários países tem mostrado consistentemente as adequadas propriedades métricas do instrumento e a sua convergência empírica e conceptual com outras medidas da personalidade normal e patológica (Al-Dajani, Gralnick, & Bagby, 2016;.…”

Personality Disorder in Childhood and Adolescence comes of Age: a Review of the Current Evidence and Prospects for Future Research

“…Research has convincingly demonstrated that normal and abnormal personality are part of the same spectrum, and display a similar higher-order factor structure across age groups (22,(82)(83)(84)(85)(86)(87). However, Western folk psychology generally views children and adolescents as having personalities that are unstable or "under construction" whereas adult personalities are perceived as relatively unchanging (51,88).…”

Psychometric Qualities of the Dimensional Assessment of Personality Pathology – Short Form for Adolescents

“…A similar problem occurs when using alternative dimensional measures to assess adolescent personality pathology. For example, although a recent study provides preliminary evidence for the psychometric quality and construct validity of the Personality Inventory for DSM-5 in adolescents (27), the instrument, which contains 220 items, is quite lengthy. Thus, the assessment of personality pathology dimensions in adolescents may be benefitted by the development of shortened versions of established measures.…”
