Abstract Background: Health-related quality of life (HRQoL) is a multidimensional construct that reflects physical, emotional, and social well-being. Personality Disorders are newly conceptualized as dimensional impairment in personality functioning that consist of the self-related (Identity and Self-Direction) and interpersonal (Empathy and Intimacy) personality functioning. Difficulties in levels of personality functioning may affect subjective perceptions of HRQoL. However, limited research has explored how impaired personality functioning (IPF) influences HRQoL during adolescence.

Aim: Preliminary findings on the association between impaired personality functioning and HRQoL, using data from the EARLY project, are presented. The EARLY project is an international, multi-site, longitudinal study investigating early signs and the developmental trajectories of personality impairments from childhood to adulthood across cultures.

Methods: Data from N = 216 adolescents (mean age = 14.0 years, 48 % female) were analyzed. IPF was assessed using the Level of Personality Functioning Questionnaire 12-18 years (LoPF-Q 12-18). HRQoL was measured with the KIDSCREEN-10 index. Two linear regression models were calculated to examine the predictive value of IPF on HRQoL.
Results: A model including the four domains of personality functioning (Identity, Self-direction, Empathy, Intimacy) explained 55 % of the variance in HRQoL (R2 = .55, p < .001). A second model using the total IPF score explained 53 % of the variance (R2 = .53, p < .001).

Conclusion: Preliminary findings suggest a strong association between IPF and perceived HRQoL in adolescents. These results underscore the importance of addressing personality-related difficulties in clinical interventions to improve quality of life outcomes in young individuals.
