The roles of personality traits and close social contact in the expression of momentary borderline personality disorder symptoms in daily life.

ABSTRACT: Dimensional models of personality, such as the five-factor model (FFM), have demonstrated strong coherence with the presentation of personality disorders, including borderline personality disorder (BPD). Given that select personality trait elevations have been linked to impairments in multiple life domains across diagnostic groups, we sought to replicate findings from a previous investigation of the utility of the FFM in predicting BPD-relevant outcomes (i.e., negative affect intensity and instability, impulsivity, and interpersonal disagreements) in the daily lives of those with BPD (Hepp et al., 2016) and community participants. As interpersonal context is instrumental in determining the strength of effects observed in studies examining individuals with BPD, we utilized ecological momentary assessment across 3 weeks (6 times daily; n_total = 15,889) to test whether close social contact (CSC) would moderate the effects of personality on momentary outcomes. Overall, results suggest that CSC is an important moderator between the effects of personality and daily life outcomes for individuals with BPD (N = 56), but not for community individuals (N = 60). For individuals with BPD, CSC may function as both a protective buffer and a risk factor, depending on outcome. For example, CSC attenuates experience of negative affect intensity for individuals with elevated neuroticism, but CSC may predict more frequent disagreements for individuals who report lower agreeableness. We replicated approximately half of the original study's findings, and results support that FFM personality is predictive of BPD-relevant outcomes broadly. However, interpersonal context is key to understanding these relationships for individuals with BPD. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Project description:Humans engage in social interactions and have a fundamental need and motivation to establish and maintain social connections. Neuroimaging studies particularly focused on the neural substrates of social exclusion in healthy subjects (HC), borderline personality disorder (BPD), and major depression (MD). However, there is evidence regarding neural alterations also during social inclusion in BPD that we intended to elucidate in our study. Considering that patients with BPD often have comorbid MD, we investigated patients with BPD, and comorbid MD, patients with MD without BPD, and a sample of HC. By investigating these two clinical samples within one study design, we attempted to disentangle potential confounds arising by psychiatric disorder or medication and to relate neural alterations under social inclusion specifically to BPD. We investigated 48 females (15 BPD and MD, 16 MD, and 17 HC) aged between 18 and 40 years by fMRI (3T), using the established cyberball paradigm with social exclusion, inclusion, and passive watching conditions. Significant group-by-condition interaction effects (p < 0.05, FWE-corrected on cluster level) were observed within the dorsolateral (dlPFC) and dorsomedial prefrontal cortex (dmPFC), the temporo-parietal junction (TPJ), the posterior cingulate cortex (PCC), and the precuneus. Comparisons of estimated neural activations revealed that significant interaction effects were related to a relative increase in neural activations during social inclusion in BPD. In detail, we observed a significant increase in differential (social inclusion vs. passive watching) neural activation within the dmPFC and the PCC in BPD compared to both, MD and HC. However, significant interaction effects within the dlPFC and the TPJ could not specifically be linked to BPD considering that they did not differ significantly between the two clinical groups in post-hoc comparisons. Our study supports previous results on effects of social and inclusion in BPD, and provides further evidence regarding disorder specific neural alterations in BPD for brain regions associated with self-referential and mentalizing processes during social inclusion.
