This study clarified the association of maladaptive, potentially self-damaging behaviors with suicidality. Specifically, we examined whether greater frequency (i.e., how often) or greater versatility (i.e., how many ways) of several self-damaging behaviors, including non-suicidal self-injury (NSSI), substance use, and disordered eating, increased risk for suicide. Participants who engaged in NSSI (N = 142) completed questionnaires assessing suicidal and self-damaging behavior at baseline and engagement in suicidal behaviors (e.g., ideation, attempts, talking about suicide) 3 months later. Results suggest that the versatility rather than frequency of self-damaging behaviors is most robustly associated with suicide risk. Engaging in multiple methods of NSSI and using a greater number of illicit substances were positively associated with suicide risk. Further, versatility of NSSI interacted with depression to predict suicide risk at 3-month follow-up such that highly depressed participants who engaged in more methods of NSSI exhibited highest risk, whereas those who engaged in more methods with low depression exhibited the lowest risk.

This laboratory study examined the emotional reactivity of persons with heightened borderline personality (BP) features to a social rejection stressor. Participants with high levels of BP features (n = 43) and controls with low levels of BP features (n = 67) were randomly assigned to a condition involving negative evaluation and social rejection based on personal characteristics, or to a condition involving a frustrating arithmetic task and negative evaluation based on performance. Hypotheses were that the high-BP individuals would demonstrate greater increases in negative emotions, shame, and anger in response to the social rejection/negative evaluation stressor, compared with the frustrating arithmetic task. The high-BP group showed significant increases in negative emotions in both conditions, significant increases in shame only in the frustrating arithmetic task, and significant increases in hostility only in the social rejection condition. In contrast, low-BP controls showed significant increases in negative emotions generally in the frustrating arithmetic condition and shame specifically in the social rejection condition. These findings highlight the emotion and context-specific nature of emotional reactivity in relation to BP features.

Background and Purpose: Conditions associated with frailty are common in people experiencing stroke and may explain differences in outcomes. We assessed associations between a published, generic frailty risk score, derived from administrative data, and patient outcomes following stroke/transient ischemic attack; and its accuracy for stroke in predicting mortality compared with other measures of clinical status using coded data. Methods: Patient-level data from the Australian Stroke Clinical Registry (2009–2013) were linked with hospital admissions data. We used International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes with a 5-year look-back period to calculate the Hospital Frailty Risk Score (termed Frailty Score hereafter) and summarized results into 4 groups: no-risk (0), low-risk (1–5), intermediate-risk (5–15), and high-risk (>15). Multilevel models, accounting for hospital clustering, were used to assess associations between the Frailty Score and outcomes, including mortality (Cox regression) and readmissions up to 90 days, prolonged acute length of stay (>20 days; logistic regression), and health-related quality of life at 90 to 180 days (quantile regression). The performance of the Frailty Score was then compared with the Charlson and Elixhauser Indices using multiple tests (eg, C statistics) for predicting 30-day mortality. Models were adjusted for covariates including sociodemographics and stroke-related factors. Results: Among 15 468 adult patients, 15% died ≤90 days. The frailty scores were 9% no risk; 23% low, 45% intermediate, and 22% high. A 1-point increase in frailty (continuous variable) was associated with greater length of stay (OR adjusted , 1.05 [95% CI, 1.04 to 1.06), 90-day mortality (HR adjusted , 1.04 [95% CI, 1.03 to 1.05]), readmissions (OR adjusted , 1.02 [95% CI, 1.02 to 1.03]; and worse health-related quality of life (median difference, −0.010 [95% CI −0.012 to −0.010]). Adjusting for the Frailty Score provided a slightly better explanation of 30-day mortality (eg, larger C statistics) compared with other indices. Conclusions: Greater frailty was associated with worse outcomes following stroke/transient ischemic attack. The Frailty Score provides equivalent precision compared with the Charlson and Elixhauser indices for assessing risk-adjusted outcomes following stroke/transient ischemic attack.
