While facets of both anxiety and impulsivity appear central to the development and maintenance of bulimia nervosa (BN), specific BN behaviors may be propagated by differing profiles of risk. The current study examined associations between dimensions of anxiety and impulsivity and BN symptoms (binge eating, vomiting, laxative misuse, driven exercise), both in terms of the presence of such behaviors and their frequency. Two hundred and four women (M_age = 25.7 years) who met DSM-IV criteria for full or subthreshold BN completed self-report measures of perfectionism (Frost Multidimensional Perfectionism Scale), anxiety (Spielberger Trait Anxiety Inventory), impulsivity (Barratt Impulsiveness Scale-11; Impulsive Behavior Scale), eating disordered behaviors (Eating Disorder Examination - Questionnaire), and associated psychiatric symptoms (Michigan Assessment Screening Test/Alcohol-Drug; Maudsley Obsessive-Compulsive Inventory). Factor analysis revealed multidimensional impulsive and anxiety-related traits (5 anxiety-related factors; 7 impulsivity-related factors). In zero-sensitive regression models, different facets of impulsivity evidenced association with the presence of binge eating (risk taking), laxative misuse (impulsive spending), and fasting (difficulty concentrating), along with the frequency of vomiting (long-term planning difficulties). In contrast, anxiety-related dimensions were only associated with driven exercise (high standards) and fasting (concern over mistakes, high standards, parental expectations). Overall, impulsive and anxiety-related factors and symptoms showed distinct associations with specific eating disorder behaviors, even among those with the same diagnosis.

Individuals with bulimia nervosa report elevated rates of childhood maltreatment, which appears to increase risk for co-occurring substance use problems and negatively impact clinical course. The current study sought to examine the mechanistic pathways by which specific forms of childhood maltreatment may give rise to substance use problems among individuals with bulimic-spectrum pathology. Women with bulimic-spectrum disorders (N = 204) completed measures of childhood trauma, emotion dysregulation, impulsivity, and substance use. Path analysis was used to examine emotion dysregulation and impulsivity as mediators of the relationship between distinct forms of childhood trauma (physical abuse, physical neglect, emotional abuse, emotional neglect, and sexual abuse) and the presence of problematic alcohol/drug use. In the full path model, significant pathways from childhood emotional abuse to emotion dysregulation, childhood emotional neglect to impulsivity, and emotion dysregulation to problematic substance use emerged. Further, emotion dysregulation significantly mediated the relationship between emotional abuse and substance use. Results indicate that emotion dysregulation may be an important mechanism linking a history of childhood emotional maltreatment to later eating and substance use problems, and therefore may be an important treatment target among individuals with co-occurring eating and substance use concerns.Childhood emotional abuse was related to greater emotion dysregulation.Childhood emotional neglect was related to greater impulsivity.Emotion dysregulation was related to greater problematic substance use.Emotional abuse may impact substance use through emotion dysregulation.Creating emotion dysregulation may improve substance and eating disorder symptoms.

Objective

The current study explored the clinical meaningfulness of distinguishing subjective (SBE) from objective binge eating (OBE) among individuals with threshold/subthreshold bulimia nervosa (BN). We examined relations between OBEs and SBEs and eating disorder symptoms, negative affect, and personality dimensions using both a group comparison and a continuous approach.

Method

Participants were 204 adult females meeting criteria for threshold/subthreshold BN who completed questionnaires related to disordered eating, affect, and personality.

Results

Group comparisons indicated that SBE and OBE groups did not significantly differ on eating disorder pathology or negative affect, but did differ on two personality dimensions (cognitive distortion and attentional impulsivity). Using the continuous approach, we found that frequencies of SBEs (not OBEs) accounted for unique variance in weight/shape concern, diuretic use frequency, depressive symptoms, anxiety, social avoidance, insecure attachment, and cognitive distortion.

Discussion

SBEs in the context of BN may indicate broader areas of psychopathology.

Introduction

The role of interpersonal factors has been proposed in various models of eating disorder (ED) psychopathology and treatment. We examined the independent and interactive contributions of two interpersonal-focused personality traits (i.e., social avoidance and insecure attachment) and reassurance seeking in relation to global ED psychopathology and depressive symptoms among women with bulimia nervosa (BN).

Method

Participants were 204 adult women with full or subclinical BN who completed a battery of self-report questionnaires. Hierarchical multiple OLS regressions including main effects and interaction terms were used to analyze the data.

Results

Main effects were found for social avoidance and insecure attachment in association with global ED psychopathology and depressive symptoms. In addition, two-way interactions between social avoidance and reassurance seeking were observed for both global ED psychopathology and depressive symptoms. In general, reassurance seeking strengthened the association between social avoidance and global ED psychopathology and depressive symptoms.

Conclusion

These results demonstrate the importance of reassurance seeking in psychopathology among women with BN who display personality features characterized by social avoidance.

Objective: Suicide attempts and self-injurious behaviors (SIBs) are known to be elevated among people with bulimia nervosa (BN). The aim of the current study was to examine the Interpersonal-Psychological Theory of Suicide (IPTS) as a framework for understanding, assessing, and mitigating suicidal behavior among women with BN. The IPTS suggests that for individuals to enact lethal suicide attempts, they must have both the desire to die (consisting of thwarted belongingness and perceived burdensomeness) as well as the capability to die (often acquired through repeated exposure to provocative or painful experiences).Method: Two-hundred and four women with eating disorders, the majority of whom met criteria for a current DSM-IV diagnosis of BN, completed measures from which proxies for IPTS variables were formed. Bivariate correlations and multiple regressions tested main effects and interactions of study variables. Tests of the difference between dependent correlations probed differential associations between study variables and suicidal ideation versus suicidal behavior.Results and Conclusions: Results yielded considerable but not unalloyed support for the theory, with desire to die variables (particularly perceived burdensomeness) more strongly associating with suicidal ideation than behavior, and the opposite holding true regarding capability. These findings suggest that the IPTS may provide a useful framework for understanding, assessing, and mitigating suicide risk among individuals with BN.

Purpose

The purpose of this study was to explore the association between specific forms of childhood abuse and neglect with lifetime suicide attempts in women with bulimia nervosa (BN).

Methods

Two hundred and four women aged 18-65 (mean 25.6 years, SD 9.13) with full or subclinical BN were recruited in five US Midwestern communities and specialized eating disorder clinics. Participants completed questionnaires including the Childhood Trauma Questionnaire (CTQ) and self-reported whether they had ever had a lifetime suicide attempt. Logistic regression analyses were used to predict lifetime suicide attempts from each subscale of the CTQ.

Results

Childhood emotional, physical, and sexual abuse were significantly associated with the presence of a lifetime suicide attempt in women with BN. Childhood emotional and physical neglect were not associated with suicide attempts.

Conclusions

Individuals with BN who have experienced childhood emotional and sexual abuse are at increased risk of a lifetime suicide attempt. Future research is needed to understand the mechanism to address in treatment and prevention efforts. It is important for clinicians to be aware of the potential increased risk of suicide in individuals with BN with a history of childhood abuse.

The current study explores the personality traits of compulsivity (e.g., sense of orderliness and duty to perform tasks completely) and restricted expression (e.g., emotion expression difficulties) as potential moderators of the relation between affect lability and frequency of hard exercise episodes in a sample of individuals with bulimic pathology. Participants were 204 adult females recruited in five Midwestern cities who met criteria for threshold or subthreshold bulimia nervosa (BN). Compulsivity was found to significantly moderate the relation between affect lability and number of hard exercise episodes over the past 28 days, such that among those with high compulsivity, level of affect lability was associated with the number of hard exercise episodes; whereas, among those with low compulsivity, affect lability was not associated with the number of hard exercise episodes. The same pattern of findings emerged for restricted expression; however, this finding approached, but did not reach statistical significance. As such, it appears that affect lability is differentially related to hard exercise among individuals with BN depending upon the level of compulsivity and, to a more limited extent, restricted expression. These results suggest that, for individuals with BN with either compulsivity or restricted expression, focusing treatment on increasing flexibility and/or verbal expression of emotions may help in the context of intense, fluctuating affect.
