Clinical profiles of adolescents using a dimensional conceptualisation of personality pathology: A latent structure examination of the Semi-Structured interview for Personality Functioning DSM-5 (STiP-5.1) in a help-seeking sample (Unpublished). In: IEPA's 14th International Conference on Early Intervention in Mental Health. Lausanne, Switzerland. 10.07.-12.07.2023.
Aims: Despite the introduction of dimensionally oriented Criterion A in the assessment of personality pathology, heterogeneous clinical presentation remains a challenge. Relatedly, the latent structure of the Semi-Structured interview for Personality Functioning DSM-5 (STiP-5.1) as a measure of Criterion A has not yet been comprehensively examined in adolescents. This study aimed to first identify the best fitting model for the latent structure of the STiP-5.1, and then to describe unique clinical profiles.
Methods: A total of 502 participants aged between 11-18 years assessed using the STiP-5.1, comprised the final sample. The best fitting model was first identified by comparing variations of Factor Analysis, Latent Class Analysis and Factor Mixture Models (FMM) using the STiP-5.1. The unique profiles were then further characterised by STiP-5.1 elements and other clinical variables, as compared to the overall sample.
Results: The best fitting model was identified as an FMM comprising four-classes and two factors. The four unique classes differed in both overall severity (with the exception of two classes), and in their scores and clinical relevance on each element of the STiP-5.1 (identity, self-direction, empathy, and intimacy). When compared to the overall sample on STiP-5.1 and other clinical variables, each class differed in its unique clinical presentation.
Conclusions: A complex model incorporating both dimensional and categorical components most adequately conceptualises the latent structure of the STiP-5.1 in our adolescent sample. The four unique classes yielded can help to parse out clinical heterogeneity in personality pathology in adolescents, and inform early identification and intervention efforts.
