A Comparison of Adolescent versus Young Adult Outpatients with First-Presentation Borderline Personality Disorder: Findings from the MOBY Randomized Controlled Trial.

OBJECTIVE: The increasing focus on adolescent personality disorder has tended to ignore evidence of the developmental continuity of the period from puberty to young adulthood. This study aims to: (1) describe the characteristics of a sample of young people with borderline personality disorder (BPD) who had no previous history of evidence-based treatment for the disorder and (2) compare their characteristics by participant age group. METHODS: One hundred and thirty-nine young people (15 to 25 years) with BPD, newly enrolled in the Monitoring Outcomes of BPD in Youth randomized controlled trial, completed semi-structured interview and self-report measures assessing demographic, clinical, and functional characteristics. Younger (aged 15 to 17 years; n = 64) and older (aged 18 to 25 years; n = 75) participants were compared on these same variables using t-tests, chi-square tests, and logistic regression. RESULTS: Young outpatients with BPD had extensive and severe psychopathology and were functioning poorly. Adolescents and young adults with BPD showed substantial similarities on 20 key aspects of their presentation. Significant between-groups differences were observed in household makeup, treatment history, antisocial personality disorder, emotion dysregulation, substance use, age of commencement and extent of self-harm, and achievement of age-appropriate educational milestones. Adolescent BPD group membership was predicted by family composition and self-harm, whereas young adult BPD group membership was predicted by not achieving age-appropriate milestones, vocational disengagement, and emotion dysregulation. The final model explained 54% of the variance and correctly classified 80.2% of the sample by age. CONCLUSIONS: Both adolescents and young adults with early stage BPD present with severe and often similar problems to one another, supporting developmental continuity across this age range. However, there are also meaningful differences in presentation, suggesting that pathways to care might differ by age and/or developmental stage. Detection and intervention for personality disorder should not be delayed until individuals reach 18 years of age.

Prevalence and influence of psychiatric comorbidity on rehabilitation outcome for older hospital inpatients.

BACKGROUND: The objectives of this study were to characterize the psychiatric comorbidity of a group of older subacute inpatients and then determine whether their psychiatric comorbidity affected measures of rehabilitation outcomes. METHODS: Eighty-eight older subacute inpatients were recruited for this prospective study. Psychiatric comorbidity was defined according to a participants' performance on four inventory scales: the Geriatric Depression Scale (GDS), Geriatric Anxiety Inventory (GAI), Brief Psychiatric Rating Scale and Health of the Nation Outcome Scale 65+. Rehabilitation outcome referred to the participants' length of stay and their performance at discharge on the EuroQol-5D health-related quality of life questionnaire and Barthel index. RESULTS: 68% of the participants scored in the clinical range on at least one of the four scales assessing psychiatric comorbidity at admission, with 51% in the clinical range for GDS and 32% for the GAI. The decrease in scores by the time of discharge was significant for all four scales. Linear regression analyses pointed to a trend for depressive symptoms at admission to be an influential but nonsignificant predictor of rehabilitation outcome. An interesting association was found between the length of the previous acute admission and the GDS score on admission to the subacute unit. CONCLUSION: A high prevalence of psychological symptoms was identified upon admission, with a significant decrease by the time of discharge. These factors did not significantly predict the selected measures of rehabilitation outcome. Opportunities for future longitudinal research on the prevalence and impact of psychiatric comorbidities on patient outcomes are considered.
