Obesity is a major public health concern, and sugar consumption is a key risk factor for obesity. Thus, there is a need to identify factors that may increase motivation to consume sugar. One such factor may be negative affect, as research has shown that negative affect increases motivation for and engagement in appetitive behaviors, including sugar...
Article
Background: Disability status is associated with correlates of suicide risk (perceived burdensomeness, thwarted belongingness, negative future disposition, felt stigma, suicidal ideation, and suicide attempts). Aims: This study aimed to examine whether suicide-related correlates differ significantly as a function of disability type. Methods: I...
Article
Nonsuicidal self‐injury (NSSI) is defined as the deliberate destruction of one's own body tissue without suicidal intent and for purposes not socially sanctioned. However, this definition limits the understanding and assessment of NSSI by excluding a clinically relevant form of NSSI that is both self‐driven and associated with self‐injurious intent...
Article
Introduction: Suicide models propose that the capability for suicide, such as fearlessness about death (FAD), is necessary for the transition from suicidal desire to a suicide attempt. Most studies have relied on self-report methods to assess FAD. However, this research has produced equivocal results. As individuals may have limited awareness of l...
Article
Background Despite the strong link between borderline personality disorder (BPD) symptoms and suicide risk, little is known about the mechanisms underlying this association. Theory-driven research clarifying the pathways through which BPD symptoms increase suicide risk over time is needed and may highlight relevant treatment targets for decreasing...
Article
Despite often being mandated to substance use treatment after release, many people on probation do not complete treatment. Several historical factors have been identified as relevant to substance use treatment in this population (i.e., past substance use, treatment history, and criminal history); however, less is known about the psychological chara...
Article
Objective: This study examined the associations of the experience and tolerance of shame-related emotions to suicide risk, as well as the moderating role of sexual minority status. Methods: Community adults (N = 360) were recruited via MTurk and completed self-report questionnaires. Hierarchical regression analyses examined the main and interact...
Article
Objectives: Emotional and interpersonal dysfunction appears central to nonsuicidal self-injury (NSSI), yet research examining the interplay of these factors among individuals with NSSI is limited. This study aimed to specify such associations before and after daily stressful events among individuals with (vs. without) NSSI. Methods: Young adult...
Article
Maternal borderline personality disorder (BPD) symptoms have been found to relate to parenting difficulties that subsequently predict children's maladjustment. One specific area of difficulty for mothers with BPD symptoms surrounds responses to infant distress. Based in mentalization theories of BPD, the current study tested the relation between BP...
Article
Introduction: People report multiple motives for nonsuicidal self-injury (NSSI), but few studies have examined how these motives relate to one another. This study identified person-centered classes of NSSI motives, their NSSI and psychopathological correlates, and their utility in predicting future NSSI across two samples. Methods: Participants...
Article
Background Despite research and theory linking emotion regulation (ER) difficulties to suicidal thoughts and behaviors, limited research has examined the relations of specific ER strategies to suicide risk outcomes, and almost no research has examined interpersonal ER strategies in particular. Thus, this study sought to examine associations of spec...

Objectives Extant research indicates a robust association between anxiety and nonsuicidal self-injury (NSSI). However, research identifying factors that may account for this relation is lacking. Mindfulness is one candidate construct that may account for the relation of anxiety to NSSI. The objective of the present study was to examine the indirect...
Article
Background Pain anxiety has been associated with more severe posttraumatic stress disorder (PTSD) symptoms. However, the unique role of individual domains of pain anxiety has yet to be explored in the prediction of PTSD severity. This study examined whether specific pain anxiety domains (i.e., cognitive anxiety, escape/avoidance, fear of pain, and...
Article
This study sought to examine the explanatory role of sleep disturbance in the associations of borderline personality disorder (BPD) symptom severity to nonsuicidal self‐injury (NSSI) and suicide risk within an at‐risk sample of patients with substance use disorders (SUDs), as well as whether emotion regulation (ER) difficulties account for signific...
Article
There is a need to identify the subset of individuals with borderline personality disorder (BPD) symptoms at greatest risk for transitioning from suicidal ideation to a suicide attempt. Contemporary models of suicide risk propose that the capability for suicide is necessary for moving from suicidal ideation to a suicide attempt. Few studies have ex...
Article
Given concerns of increased suicide risk among university students during the COVID-19 pandemic, this study examined rates of lifetime and past-year suicidal ideation (SI) among university students in Fall 2020 (vs. two earlier semesters), overall and across gender, racial/ethnic background, and sexual identity. Participants included 1700 universit...

Introduction: Theory and research suggest the need to expand research on emotion regulation (ER) within borderline personality disorder (BPD). This research examined the relations of BPD symptoms to interpersonal (venting, reassurance-seeking) and socially-oriented (social comparison) ER strategies (in addition to acceptance and avoidance), and exp...
Article
Emotion dysregulation has been shown to be of importance in the onset and maintenance of psychiatric disorders, including substance use disorders. How difficulties in emotion regulation differ across levels of substance use, and whether these relations are influenced by co-occurring psychiatric disorders, is less clear. This study aimed to identify...
Article
Despite the established relations between borderline personality disorder (BPD) and substance use problems in general, there is a dearth of research on the relation between BPD pathology and opioid use problems, as well as factors that may explain this relation. Therefore, this study examined the indirect relations of BPD pathology to opioid use pr...
Article
Research has largely not identified processes contributing to the relationship between physical disability and suicide risk. This cross-sectional research is aimed at examining the associations among felt stigma, perceived burdensomeness, disability severity, and perceptions about future suicidal ideation and attempts. Adults (N = 127) with physica...
Article
Little research has examined the role of emotion regulation self-efficacy (ERSE; i.e., beliefs in one's own ability to regulate emotions) in self-injurious thoughts and behaviors (SITBs) or the factors that may underlie this relation. This study investigated whether low ERSE relates to SITBs both directly and indirectly through avoidance of negativ...
Article
Objective Although once considered a defining feature of borderline personality disorder, research has found high rates of NSSI among individuals with other psychiatric disorders, particularly posttraumatic stress disorder (PTSD) and depressive disorders. A recent study from our research team found that lifetime PTSD and depressive disorders were a...
Article
Cancer survivors are more at risk for physical and psychological health problems than the general population. Regular aerobic physical activity can mitigate these risks, but survivors frequently fail to engage in recommended levels of physical activity. In the present study, we propose and test a moderated-mediation model of physical activity of ca...
Article
The COVID-19 pandemic is likely to increase risk for the development of health anxiety. Given that elevated health anxiety can contribute to maladaptive health behaviors, there is a need to identify individual difference factors that may increase health anxiety risk. This study examined the unique and interactive relations of COVID-19 affective ris...
Article
Background : Despite theories that negative reinforcement in the form of relief from negative emotions maintains nonsuicidal self-injury (NSSI), no studies have examined the extent to which specific emotional consequences of NSSI predict the maintenance of NSSI over time or explain the greater risk for NSSI found among individuals with borderline p...
Article
Full-text available
Objective The social and economic consequences of COVID‐19 and related public health interventions aimed at slowing the spread of the virus have been proposed to increase suicide risk. However, no research has examined these relations. This study examined the relations of two COVID‐19 consequences (i.e., stay‐at‐home orders and job loss) to suicide...
