Evaluating the role of negative affect and negative interpretation biases in emotional eating behavior.

OBJECTIVE: The study of emotional eating, or (over)eating in response to emotions, may inform transdiagnostic interventions for eating pathology. Prior work has focused on the role of negative affect in promoting emotional eating. The present study sought to extend this work through examining the role of cognitive biases. METHOD: Women who self-reported (n = 50) and did not self-report (n = 40) emotional eating completed self-report questionnaires of negative affect and negative interpretation biases, an implicit measure of cognitive bias, and a behavioral assay of emotional eating involving an ad lib test meal following a stress induction task. RESULTS: The emotional eating group endorsed elevated trait negative affect, explicit shame biases, and implicit negative biases compared to controls. In addition, state negative affect increased after the stress induction task, and the emotional eating group endorsed greater state negative affect before and after the task and consumed more food following the stress induction. Only explicit cognitive shame biases demonstrated significant indirect effects in the association between group and food consumption. Specifically, elevated explicit shame biases were positively associated with amount of food consumed for the emotional eating group. DISCUSSION: Future research should examine whether interventions that target cognitive biases related to shame reduce emotional eating. PUBLIC SIGNIFICANCE: Individuals with emotional eating consumed more food than controls following a stress induction. Explicit shame cognitive biases were positively associated with amount of food consumed for the emotional eating group. Shame cogntiive biases may be fruitful targets for reducing emotional eating.

Evaluating the predictive validity of purging disorder by comparison to bulimia nervosa at long-term follow-up.

OBJECTIVE: The current study sought to examine the predictive validity of the purging disorder diagnosis at long-term follow-up by comparing naturalistic outcomes with bulimia nervosa. METHOD: Women with purging disorder (N = 84) or bulimia nervosa (N = 133) who had completed comprehensive baseline assessments as part of one of three studies between 2000 and 2012 were sought for follow-up assessment. Nearly all (94.5%) responded to recruitment materials and 150 (69% of sought sample; 83.3% non-Hispanic white; 33.40 [7.63] years old) participated at an average of 10.59 (3.71) years follow-up. Participants completed the Eating Disorder Examination, the Structured Clinical Interview for DSM-IV, and a questionnaire battery. Diagnostic groups were compared on eating disorder (illness status, recovery status, and eating pathology) and related outcomes. Group differences in predictors of outcome were explored. RESULTS: There were no significant differences in eating disorder presence (p = .70), recovery status (p = .87), and level of eating pathology (p = .17) between diagnostic groups at follow-up. Post hoc equivalence tests indicated group differences were smaller than a medium effect size (p's ≤ .005). Groups differed in diagnosis at follow-up (p = .002); diagnostic stability was more likely than cross-over to bulimia nervosa for women with baseline purging disorder (p = .004). DISCUSSION: Although purging disorder and bulimia nervosa do not differ in long-term outcomes, the relative stability in clinical presentation suggests baseline group differences in clinical presentation may be useful in augmenting treatments for purging disorder. PUBLIC SIGNIFICANCE STATEMENT: While purging disorder is classified as an "other specified" eating disorder, individuals who experience this disorder have comparable negative long-term outcomes as those with bulimia nervosa. This highlights the importance of screening for and treating purging disorder as a full-threshold eating disorder.

Examining the Clinical Correlates of Overeating and Binge-Eating Behaviors Among U. S. Veterans.

INTRODUCTION: Pressure to meet U.S. military weight requirements during service may predispose some service members to develop psychiatric disorders such as eating disorders or unhealthy eating behaviors, which may persist after military discharge. Specifically, research examining U.S. military veterans has found that in weight management programs, veterans with binge-eating behaviors have shown poor treatment outcomes. Overall, previous research suggests that veterans experience considerable and persistent disordered eating problems, and in addition may experience a higher prevalence of disordered eating in comparison to the general U.S. population. Research on Post-9/11 Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) veterans is needed as this group frequently presents with high rates of medical and psychiatric disorders. The current study used clinician-administered structured interviews to examine relationships between psychiatric, health, and demographic variables in a sample of Post-9/11 OEF/OIF/OND veterans with binge-eating or overeating behavior or neither. MATERIALS AND METHODS: This article presents secondary analyses of the baseline phase from data obtained for the Survey of the Experiences of Returning Veterans. Using structured phone interviews, we cross-sectionally examined patterns of medical comorbidities between sociodemographic, health, eating, and psychiatric variables in 846 recently deployed U.S. veterans with binge-eating behaviors (reporting both overeating and loss of control [LOC] eating), overeating behaviors (overeating without LOC), or healthy controls (absence of any disordered eating). Study procedures were approved by the Department of Veterans Affairs (VA) Institutional Review Boards, and informed consent was obtained from the participants. A series of chi-square and analysis of variance tests revealed significant bivariate between-group differences in sociodemographic, health, eating, and psychiatric variables. Variables with significant group differences (P < .05) were entered into a multinomial logistic regression to examine relationships between psychiatric, health, and eating factors and binge-eating severity. RESULTS: Results of the multinomial logistic regression analysis showed that women relative to men were less likely to overeat. When comparing the binge-eating group and controls, higher body mass index was associated with higher odds of binge eating. Furthermore, for the overeating group in comparison to controls, fasting behavior was associated with higher odds of overeating. For the psychiatric variables, the binge-eating and overeating groups were associated with higher rates of compulsive buying when compared to healthy controls. Additionally, the overeating group was associated with higher rates of alcohol dependence. Lastly, binge-eating and overeating behaviors were positively associated with specific psychiatric and health comorbidities. CONCLUSIONS: Further research is needed to inform the development of effective treatments for disordered eating problems, as evidenced by an anticipated increase of veterans entering the VA healthcare system and the high rate of binge eating observed in our study and prior research in Post-9/11 veterans. Moreover, our study findings suggest the relevance of screening veterans for compulsive buying. This study was limited by its relatively small sample which only examined disordered eating behaviors. Future studies could simultaneously explore binge-eating behaviors and binge-eating disorder diagnoses in larger samples. Study strengths include a diverse sample of Post-9/11 veterans with sizable female representation.

A naturalistic, long-term follow-up of purging disorder.

BACKGROUND: The DSM-5 introduced purging disorder (PD) as an other specified feeding or eating disorder characterized by recurrent purging in the absence of binge eating. The current study sought to describe the long-term outcome of PD and to examine predictors of outcome. METHODS: Women (N = 84) who met research criteria for PD completed a comprehensive battery of baseline interview and questionnaire assessments. At an average of 10.24 (3.81) years follow-up, available records indicated all women were living, and over 95% were successfully located (n = 80) while over two-thirds (n = 58) completed follow-up assessments. Eating disorder status, full recovery status, and level of eating pathology were examined as outcomes. Severity and comorbidity indicators were tested as predictors of outcome. RESULTS: Although women experienced a clinically significant reduction in global eating pathology, 58% continued to meet criteria for a DSM-5 eating disorder at follow-up. Only 30% met established criteria for a full recovery. Women reported significant decreases in purging frequency, weight and shape concerns, and cognitive restraint, but did not report significant decreases in depressive and anxiety symptoms. Quality of life was impaired in the physical, psychological, and social domains. More severe weight and shape concerns at baseline predicted meeting criteria for an eating disorder at follow-up. Other baseline severity indicators and comorbidity did not predict the outcome. CONCLUSIONS: Results highlight the severity and chronicity of PD as a clinically significant eating disorder. Future work should examine maintenance factors to better adapt treatments for PD.

Routinized categorization of suicide risk into actionable strata: Establishing the validity of an existing suicide risk assessment framework in an outpatient sample.

OBJECTIVE: The Suicide Risk Assessment and Management Decision Tree (DT) is a clinician-administered assessment that leads to risk categorizations that correspond with actionable strata. This study investigated the construct validity and test-retest reliability of the DT risk categories across two time points. METHOD: Outpatients (N = 731) completed a battery of self-report measures. Spearman's correlations were used to examine the relationships between DT suicide risk level and suicidal symptoms, theory-based risk factors, psychiatric correlates, and DT suicide risk level at Timepoint 2. Correlations were analyzed for significant differences to examine the divergent validity of the DT. RESULTS: Results, overall, were in line with hypotheses, with the exception of depression and thwarted belongingness. CONCLUSIONS: Findings provide evidence for the reliability, convergent validity, and discriminant validity of the DT. This clinician-administered suicide risk assessment may be useful for standardization of the assessment and management of suicide risk in outpatient clinical settings.

A 30-year longitudinal study of body weight, dieting, and eating pathology across women and men from late adolescence to later midlife.

Eating disorders (EDs) are more common among younger women compared to older women and in women compared to men. As such, most ED research focuses on late adolescent and young adult females resulting in limited prospective research on gender differences in eating disorder psychopathology across the life span. The present study addresses this gap by examining gender differences in ED diagnoses, eating pathology, and the impact of putative risk factors on eating pathology in women (n = 624) and men (n = 276) over a 30-year period from late adolescence (M (SD) = 20[2] years) to later midlife (M (SD) = 50[2] years). Four assessment waves were conducted, beginning with baseline participation during college and subsequent 10-, 20-, and 30-year follow-up. Retention at 30-year follow-up was 72% (n = 440) for women and 67% (n = 181) for men. Prevalence of DSM-5 ED diagnoses decreased over the 30-year span for women and remained stable for men, with no significant gender difference in point prevalence by age 50. Drive for thinness decreased for women through age 50 and increased for men, while bulimic symptoms decreased as both genders aged. Multilevel models demonstrated that the impact of dieting as a risk factor on drive for thinness decreased prospectively as men aged and remained stable as women aged. Results imply that current risk models require refinement to account for developmental trajectories in which dramatic gender differences observed in late adolescence diminish over time.

Examination of parental dieting and comments as risk factors for increased drive for thinness in men and women at 20-year follow-up.

OBJECTIVE: Popular beliefs suggest that parents influence children's eating disorder risk through modeling pathological behaviors and attitudes, and this history may contribute to disordered eating in adulthood. However, the empirical basis for this popular thinking is limited by a reliance on cross-sectional designs that do not distinguish between maternal and paternal influences and use primarily child and adolescent samples. To address these limitations, the present study examined the impact of maternal and paternal dieting and comments about weight and eating, as reported by late adolescents, on the eating pathology of those late adolescents at 20-year follow-up. METHOD: Data were drawn from a longitudinal epidemiological study of health and eating patterns in a cohort of randomly sampled college students established in 1992 (N = 799; mean age: 19.87 [±1.64] years; 70.8% women) and followed 20 years later in 2012 (N = 539). RESULTS: At baseline, there were no gender differences in reported rates of maternal or paternal dieting. Both men and women reported higher levels of maternal versus paternal dieting. Further, women endorsed higher levels of maternal and paternal comments on their own weight and eating. A multivariable model in women supported that maternal dieting and paternal comments significantly predicted drive for thinness at follow-up. No parental variables predicted drive for thinness in men at follow-up. DISCUSSION: While our study supports parental influence on children's eating attitudes, it suggests a need to consider gender and mode of influence. Prevention efforts focused on challenging cultural standards of appearance may benefit from incorporation of parents. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:490-497).

A preliminary evaluation of the validity of binge-eating disorder defining features in a community-based sample.

OBJECTIVE: Little empirical attention has been paid to the DSM-5 definition of binge-eating disorder (BED), particularly to the associated features of binge episodes. The present study sought to determine how the associated features and undue influence of weight/shape on self-evaluation contribute to evidence of a clinically significant eating disorder. METHOD: Secondary analyses were conducted on data (N = 80; 76.3% women, 76.3% Caucasian, ages 18-43) collected through an epidemiological study of eating patterns. Descriptive statistics were used to report the sample prevalence of the features, independently and in combination. Correlations and alpha reliability were employed to examine relationships among associated features, distress regarding bingeing, and clinical diagnosis. Regression models and receiver-operating characteristic (ROC) curves were used to determine the utility of the features for explaining variance in distress. RESULTS: Internal consistency reliability for indicators was low, and several features demonstrated low or nonsignificant associations with distress and diagnosis. Feeling disgusted/depressed/guilty was the only unique predictor of distress (p = 0.001). For the ROC curves, three features was the best threshold for predicting distress. DISCUSSION: Results support the need to refine the features to ensure better detection of clinically significant eating pathology for research inclusion and treatment of the illness. © 2015 Wiley Periodicals, Inc.

Routinized Assessment of Suicide Risk in Clinical Practice: An Empirically Informed Update.

OBJECTIVE: Empirically informed suicide risk assessment frameworks are useful in guiding the evaluation and treatment of individuals presenting with suicidal symptoms. Joiner et al. (1999) formulated one such framework, which has provided a concise heuristic for the assessment of suicide risk. The purpose of this review is to ensure compatibility of this suicide risk assessment framework with the growing literature on suicide-related behaviors. METHODS: This review integrates recent literature on suicide risk factors and clinical applications into the existing model. Further, we present a review of risk factors not previously included in the Joiner et al. (1999) framework, such as the interpersonal theory of suicide variables of perceived burdensomeness, thwarted belongingness, and capability for suicide (Joiner, 2005; Van Orden et al., 2010) and acute symptoms of suicidality (i.e., agitation, irritability, weight loss, sleep disturbances, severe affective states, and social withdrawal). RESULTS: These additional indicators of suicide risk further facilitate the classification of patients into standardized categories of suicide risk severity and the critical clinical decision making needed for the management of such risk. CONCLUSIONS: To increase the accessibility of empirically informed risk assessment protocols for suicide prevention and treatment, an updated suicide risk assessment form and decision tree are provided.
