The present study utilized an epidemiological sample of 35,995 men and women to evaluate the extent of differential item functioning (DIF) among BPD criteria across sexual orientation groups using a multiple indicators multiple causes approach. All criteria except affective instability and emptiness indicated DIF for at least one sexual minority focal group, although both demonstrated DIF in sensitivity analyses. DIF was most consistently indicated for suicidality, efforts to avoid abandonment, and impulsivity. Contrary to predictions, DIF was mostly nonuniform with greater item discrimination for sexual minority groups compared to their heterosexual counterparts.

We aimed to address these gaps by administering a rating scale measuring (mal)adaptive identity alongside a prompt to write a narrative about a turning point event to 331 individuals aged 18-30 (72.2% female, <i>M</i><sub>age</sub> = 22.56). Using this multimethod approach, we investigated (a) associations of narrative identity dimensions (agency, communion, exploratory processing) with self-rated identity, self- and interpersonal dysfunction, and symptoms of borderline and antisocial PD, and (b) whether these narrative identity dimensions could explain unique variance in self- and interpersonal dysfunction, and borderline and antisocial PD symptoms, above and beyond self-rated identity, and vice versa. Results revealed significant associations among narrative identity, self-rated identity, and models of PD. Furthermore, communion demonstrated incremental value in explaining PD features, beyond what was accounted for by self-rated identity. However, narrative identity did not offer additional explanatory power in understanding self- and interpersonal dysfunction, beyond self-rated identity. Self-rated identity showed incremental value in explaining all PD models, beyond narrative identity.

CLPN modeling was employed to investigate the stability, potential causal relations, and subtypes of adolescent BPFs. The results revealed a relatively stable overall adolescent BPF network structure with some subtle changes over time. Impulsivity emerged as the BPF with the highest out-expected influence, indicating its predictive role for other BPFs. A strong reciprocal causal relationship was observed between impulsivity and affective instability. Based on the CLPN estimation, two distinct BPFs subgroups were spontaneously clustered: externalized-dysregulation subtype (impulsivity, affective instability, and self-harm/suicide) and introjective-disturbance subtype (identity disturbance, chronic emptiness, and stress-related dissociation). The present study tentatively explores a potential typology for adolescent BPF based on these two clusters, which possibly have different pathological mechanisms, and moreover offer insights into the essential construct and clinical intervention of adolescent BPD.

Given that BPD and EDs share emotional dysregulation and impulsivity as maintaining mechanisms of each respective disorder, these theories of binge eating may provide a model for binge eating in BPD.
