Evaluation of the Borderline Personality Features Scale for Children and Life Satisfaction in Lithuanian Adolescents

Abstract: Borderline Personality Disorder (BPD) is a diagnosis in adolescents associated with poor adult outcomes later in life. Despite developing interest in early identification of personality disorder in Lithuania, currently few valid measures exist to evaluate BPD in young people. Moreover, as yet, borderline features have not been evaluated for their association with quality of life in Lithuanian young people. This paper evaluates the psychometric properties of the Borderline Personality Features Scale for Children (BPFSC-11) in a combined community-based and clinical sample of Lithuanian adolescents. Results showed strong psychometric properties for the BPFSC-11 including good reliability, a unidimensional factor structure, configural, metric, and scalar invariance for gender and partially for age, as well as convergent validity with related constructs (personality pathology, general psychopathology). Furthermore, significant associations with life satisfaction were demonstrated. This study concludes that the BPFSC-11 appears to show similar psychometric properties in Lithuanian adolescents as in other populations.
