Little is known about the differences between age groups in maladaptive personality function as denoted in Criterion A of the Alternative Model for Personality Disorder (AMPD) in the DSM-5, which is the entry criterion for diagnosing personality disorder in the upcoming ICD-11. The current study aimed to address this gap by evaluating latent mean age group differences in maladaptive identity, which is one aspect that has been identified as an important feature of maladaptive, general personality function as represented in the DSM-5 and ICD-11. We were also interested whether mean differences would track with mean differences in borderline personality disorder (BPD) features given prior data suggesting that general personality function overlap with the construct of BPD. A community sample of N = 2,381 adolescents, representing a mix of different socio-economic and educational backgrounds, ages 12-18 (M = 14.92, SD = 1.94; 46% male) completed a measure of maladaptive identity. A subset (n = 1,165) completed a measure of borderline personality features. Latent variable modeling was used to evaluate latent mean differences across seven age bands. Results suggested a normative increase in maladaptive identity after age 12, which remained consistent until age 17 when it dropped back to levels observed in 12-year-olds. Maladaptive identity was significantly associated with mean-level increases in borderline personality features, with these constructs becoming more closely associated with increasing age.

Background: The Borderline Personality Feature Scale for Children (BPFS-C) is currently the only dimensional measure of child and adolescent borderline features and the English version has been shown to have good psychometric properties. To extend the use of this measure with French speaking adolescents, it is essential to examine the reliability and validity of the French BPFS-C. Objective: The present study sought to assess the psychometric properties of the French BPFS-C. Methods: A community sample of 394 adolescents and young adults completed the Borderline Personality Features Scale for Children (BPFS-C), as well as the Million Adolescent Clinical Inventory (MACI) borderline tendency subscale, the Child Behavior Checklist- Youth Self-Report (CBCL-YSR) and the Beck Youth Inventories (BYI). Results: The findings show that both the long and short French BPFS-C have good internal consistency and convergent validity. Affect regulation, identity, relationship difficulties and self-harm were found to be closely inter-connected rather than distinct factors. Conclusion: The findings indicate that both long and short versions of French BPFS-C have good psychometric properties and provide preliminary evidence that the total scores are reliable and valid indicators of borderline personality features in adolescents and young adults.

The current study includes Urdu translation and validation of Borderline Personality Features Scale–11 (BPFS-11) in two phases. Phase 1 included forward and back translation of BPFS-11, and Phase 2 included establishment of psychometric properties for BPFS-11. For this purpose, 930 adolescents were selected from different hospitals, schools, and colleges. The reliability value of the scale was .72. Exploratory factor analysis revealed factor structure with four principal dimensions; besides confirmatory factor analysis, goodness-of-fit indices indicated good fit of model to data, and two dimensions of scale and factors showed good values of internal consistency. The obtained value for goodness-of-fit index was .995, for adjusted goodness-of-fit index was .989, for comparative fit index was .998, for incremental fit index was .998, and for root mean square error of approximation (RMSEA) value was .019. Good values of composite reliability and convergent validity were measured for both dimensions of the scale. The analysis of criterion-related validity showed significant positive correlation of BPFS-11 with Affective Lability Scale, Deliberate Self-Harm Inventory, and neuroticism scale of Big Five Inventory. Significant differences were found between scores of individuals having borderline personality disorder and scores of normal individuals. The results of the current study indicated that BPFS-11 is short and easily administered diagnostic tool that has good psychometric properties and can be helpful for diagnosis of borderline personality features in adolescents. It can enhance the understanding of the participants regarding the statements of the scale for Urdu natives.
