Objective: The impact of the wider social environment, such as neighbourhood characteristics, has not been examined in the development of borderline personality disorder. This study aimed to determine whether the treated incidence rate of full-threshold borderline personality disorder and sub-threshold borderline personality disorder, collectively termed borderline personality pathology, was associated with the specific neighbourhood characteristics of social deprivation and social fragmentation. Method: This study included young people, aged 15–24 years, who attended Orygen's Helping Young People Early programme, a specialist early intervention service for young people with borderline personality pathology, from 1 August 2000–1 February 2008. Diagnoses were confirmed using the Structured Clinical Interview for DSM -IV Personality Disorders, and census data from 2006 were used to determine the at-risk population and to obtain measures of social deprivation and fragmentation. Results: The study included 282 young people, of these 78.0% (n = 220) were female and the mean age was 18.3 years (SD = ±2.7). A total of 42.9% (n = 121) met criteria for full-threshold borderline personality disorder, and 57.1% (n = 161) had sub-threshold borderline personality disorder, defined as having three or four of the nine Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM -IV) borderline personality disorder criteria. There was more than a sixfold increase in the treated incidence rate of borderline personality pathology in the neighbourhoods of above average deprivation (Quartile 3) (incidence rate ratio = 6.45, 95% confidence interval: [4.62, 8.98], p < 0.001), and this was consistent in the borderline personality disorder sub-groups. This association was also present in the most socially deprived neighbourhood (Quartile 4) (incidence rate ratio = 1.63, 95% confidence interval: [1.10, 2.44]), however, only for those with sub-threshold borderline personality disorder. The treated incidence of borderline personality pathology increased incrementally with the level of social fragmentation (Quartile 3: incidence rate ratio = 1.93, 95% confidence interval: [1.37, 2.72], Quartile 4: incidence rate ratio = 2.38, 95% confidence interval: [1.77, 3.21]). Conclusion: Borderline personality pathology has a higher treated incidence in the more socially deprived and fragmented neighbourhoods. These findings have implications for funding and location of clinical services for young people with borderline personality pathology. Prospective, longitudinal studies should examine neighbourhood characteristics as potential aetiological factors for borderline personality pathology. [ABSTRACT FROM AUTHOR]

Summary: Characterising sleep in young people (aged 15–25 years) with borderline personality disorder (BPD) features is crucial given the association between BPD features and sleep disturbance, negative consequences of poor sleep, and normative developmental sleep changes that occur in this age group. The present study aimed to characterise the sleep profile of young people with BPD to determine whether this profile is non‐normative and specific to BPD. Participants were 96 young people (40 with BPD features, 38 healthy individuals, and 18 young people seeking help for mental health difficulties without BPD). Sleep was measured subjectively (self‐report questionnaires) and objectively (10 days of actigraphy). Young people with BPD features reported poorer subjective sleep quality, greater insomnia symptoms and later chronotype than same‐age healthy and clinical comparison groups. Young people with BPD features also displayed irregular sleep timing, later rise times, greater time in bed and longer sleep durations than healthy young people. Those with BPD features had superior sleep quality (greater sleep efficiency, less wake after sleep onset) and longer sleep durations than the clinical comparison group. Sleep profiles were similar across young people with BPD features with and without co‐occurring depression. Overall, the findings revealed a subjective–objective sleep discrepancy and suggest that sleep‐improvement interventions might be beneficial to improve subjective sleep in young people with BPD features.

Sleep disturbance is commonly reported in young people with features of borderline personality disorder (BPD). Examining sleep quality and sleep-wake patterns in young people with features of BPD is essential to inform the development of sleep-improvement interventions. A scoping review was conducted according to the Joanna Briggs Institute methodology. The objectives were to map the literature regarding sleep in young people with features of BPD, highlight areas for further investigation, and provide methodological recommendations for future research. Seven data sets were included in the review. Young people with features of BPD had poorer objective and subjective sleep quality, disturbed sleep architecture (particularly rapid-eye-movement sleep), an increased vulnerability to delayed sleep phase syndrome, and more nightmares and dream anxiety, compared with healthy individuals. Future research should use both objective and subjective sleep measures, include clinical comparison groups, and focus specifically on young people with BPD. [ABSTRACT FROM AUTHOR]

Psychotic symptoms have been found to be relatively common among adults with borderline personality disorder (BPD), and to be a marker of BPD severity, but are not recognised in daily clinical practice in these patients. This study is the first to examine the prevalence of psychotic symptoms in 15–18-year olds with BPD features. It was hypothesised that adolescents with full-threshold BPD would have significantly more psychotic symptoms than adolescents with sub-threshold BPD features, and that both these groups would have significantly more psychotic symptoms than adolescents with no BPD features. A total of 171 psychiatric outpatients, aged 15–18 years, were assessed using a structured interview for DSM-IV personality disorder and categorised into three groups: no BPD features (n = 48), sub-threshold BPD features (n = 80), and full-threshold BPD (n = 43). The groups were compared on measures of psychopathology and functioning (e.g. Youth Self Report, Symptom Check List-90-R, SOFAS). Adolescents with full-threshold BPD reported more psychotic symptoms than the sub-threshold BPD group (p <.001), and both these groups reported more psychotic symptoms than those with no BPD features (p <.001). Adolescents with full-threshold BPD reported more confusion (p <.01), paranoia (p <.001), visual hallucinations (p <.001) and strange thoughts (p <.01), than the other two groups. Psychotic symptoms predicted group membership, determined by BPD severity, after adjusting for other psychopathology and functional impairment (p <.01). Assessment of unusual perceptual experiences, paranoia or odd thoughts is highly clinically relevant in adolescents with BPD features, as these symptoms are associated with a more severe clinical presentation of BPD.

Aim: Borderline personality disorder (BPD) is a severe mental disorder that is characterized by unstable relationships, impulsive behaviours and identity disturbance. BPD usually has its onset between puberty and young adulthood and presents disproportionately among females in clinical settings. Taken together, this makes young women with BPD a particularly vulnerable group with regard to healthy psychosexual development. It was hypothesized that female youth with BPD pathology would be more likely to score worse on measures of sexual health and safety, and to show greater uncertainty in sexual identity formation. Methods: Fifty 15 to 24 yr‐old females with 3 or more Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐IV) BPD criteria were compared with 204 females from a nationally representative sample. Both groups were interviewed using a comprehensive interview for sexual health and relationships. The patient group completed a structured diagnostic interview. Results: Young women with borderline personality pathology engaged in sexual relationships at a younger age, with more sexual partners in the previous year, in more casual relationships. They were more likely to practice unsafe sex for their first sexual experience, to be coerced into unwanted sexual activity, to be unclear about their sexual identity or their sexual attraction, and to report worse overall health status. Conclusions: BPD pathology in youth is associated with poor sexual health and safety, and uncertainty in sexual identity formation. These findings support the need for assessment of the sexuality and sexual health of youth with BPD, along with the need for routine screening in sexual health services for BPD features among high‐risk youth.
