Item Distress and risk behavior in borderline personality disorder: Motivation and self-efficacy for emotion regulation(2014) Matusiewicz, Alexis Katherine; Lejuez, Carl W; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Borderline personality disorder (BPD) is a persistent psychological disorder characterized by pervasive emotional difficulties, unstable relationships, identity disturbance and high rates of engagement in self-damaging risk behavior. Prominent theoretical perspectives on BPD suggest that the primary motivational basis for risk behavior is the regulation of negative emotional states. The goal of this study was to test several of the hypotheses suggested by emotion regulation models of risk behavior, using a rigorous experimental design. Specifically, we sought to demonstrate the causal effect of distress on risk behavior among individuals with and without BPD, and to examine motivational and self-regulatory mediators of: a) the relationship between emotion and engagement in risk behavior; and b) the relationship between BPD and distress-induced change in risk behavior. To this end, participants with and without BPD provided ratings of emotion, motivation for emotion regulation and risk behavior in the context of induced calm and distress, and completed a self-report measure of trait self-efficacy for emotion regulation. Results provide partial support for the study hypotheses. Only women with BPD showed an increase in risk behavior in the distress condition, and distress-induced change in risk behavior was predicted by both the intensity of emotion regulation goals and self-efficacy for emotion regulation. Findings support the perspective that risk behavior is enacted strategically in response to negative emotions and associated motivational states. For those with BPD, distress-induced risk behavior may reflect a type of emotion-regulatory resourcefulness that becomes maladaptive when used inflexibly or to the exclusion of other strategies.Item Distress and risk-taking in borderline personality disorder: An examination of neurocognitive mechanisms(2010) Matusiewicz, Alexis Katherine; Lejuez, Carl W; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Borderline personality disorder (BPD) is a severe mental illness characterized by high rates of engagement in distress-induced risk behavior. Unfortunately, extant laboratory-based risk paradigms have failed to account for the role of distress in precipitating risk behavior, so many questions remain about processes mechanisms that underlie this behavior. The current study examined affect as a moderator of the relationship between diagnostic status and risk behavior, as measured by a behavioral risk task, and affective and non-affective neurocognitive functioning as potential mediators of this relationship. Results indicated that individuals with BPD engaged in more risk behavior in the distress condition than in the neutral condition, whereas individuals without BPD showed a decrease in risk behavior across the two conditions. However, corresponding changes in executive functioning were not observed, suggesting the need for continued research to identify alternative mechanisms (e.g., neurocognitive, motivational) to explain this effect.
