RESUMEN
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: To describe the frequency of self-weighing and reactions to prescribed weekly weighing among individuals with eating disorder (ED) diagnoses, and to compare individuals weighing more or less frequently on mass index (BMI) and the Eating Disorder Examination (EDE) subscales. METHOD: Baseline EDE and demographics from five studies (N = 758). RESULTS: Self-weighing was most frequent among individuals with anorexia nervosa (AN), followed by those with bulimia nervosa (BN) and binge eating disorder (BED). On average, participants reacted moderately negative to prescribed weekly weighing. No relationship between weighing frequency and BMI was evident in any sample. There was indication of greater pathology (i.e., restraint, shape concern, weight concern, global) in AN with more frequent weighing. In BN, mixed evidence emerged to support a relationship between more frequent weighing and higher shape concern, weight concern, and global score. In BED, higher restraint was found in those who weighed versus those who did not. DISCUSSION: Weighing frequency in each eating disorder (ED) sample was to some extent associated with greater ED severity, but not BMI. Future research should examine relationships between self-weighing, reactions to changing weighing frequency, and ED symptomatology in both ED and non-ED groups to understand the impact of self-weighing in heterogeneous populations. © 2016 Wiley Periodicals, Inc.

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.

Although loss of control (LOC) while eating is a core construct of bulimia nervosa (BN), questions remain regarding its validity and prognostic significance independent of overeating. We examined trajectories of objective and subjective binge eating (OBE and SBE, respectively; i.e., LOC eating episodes involving an objectively or subjectively large amount of food) among adults participating in psychological treatments for BN-spectrum disorders (n = 80). We also explored whether changes in the frequency of these eating episodes differentially predicted changes in eating-related and general psychopathology and, conversely, whether changes in eating-related and general psychopathology predicted differential changes in the frequency of these eating episodes. Linear mixed models with repeated measures revealed that OBE decreased twice as rapidly as SBE throughout treatment and 4-month follow-up. Generalized linear models revealed that baseline to end-of-treatment reductions in SBE frequency predicted baseline to 4-month follow-up changes in eating-related psychopathology, depression, and anxiety, while changes in OBE frequency were not predictive of psychopathology at 4-month follow-up. Zero-inflation models indicated that baseline to end-of-treatment changes in eating-related psychopathology and depression symptoms predicted baseline to 4-month follow-up changes in OBE frequency, while changes in anxiety and self-esteem did not. Baseline to end-of-treatment changes in eating-related psychopathology, self-esteem, and anxiety predicted baseline to 4-month follow-up changes in SBE frequency, while baseline to end-of-treatment changes in depression did not. Based on these findings, LOC accompanied by objective overeating may reflect distress at having consumed an objectively large amount of food, whereas LOC accompanied by subjective overeating may reflect more generalized distress related to one's eating- and mood-related psychopathology. BN treatments should comprehensively target LOC eating and related psychopathology, particularly in the context of subjectively large episodes, to improve global outcomes.

This study examined self-discrepancy, a construct of theoretical relevance to eating disorder (ED) psychopathology, across different types of EDs. Individuals with anorexia nervosa (AN; n = 112), bulimia nervosa (BN; n = 72), and binge eating disorder (BED; n = 199) completed semi-structured interviews assessing specific types of self-discrepancies. Results revealed that actual:ideal (A:I) discrepancy was positively associated with AN, actual:ought (A:O) discrepancy was positively associated with BN and BED, and self-discrepancies did not differentiate BN from BED. Across diagnoses, A:O discrepancy was positively associated with severity of purging, binge eating, and global ED psychopathology. Further, there were significant interactions between diagnosis and A:O discrepancy for global ED psychopathology and between diagnosis and A:I discrepancy for binge eating and driven exercise. These results support the importance of self-discrepancy as a potential causal and maintenance variable in EDs that differentiates among different types of EDs and symptom severity.

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.

Drawing on conceptual models illustrating the advantages of a multisystemic, interactive, developmental approach to understanding development, the present study examines the covariation of stress and sex hormones across the adolescent transition and the effect of early life stress (ELS) on neuroendocrine coupling to gain insight into atypical development. Morning levels of cortisol, testosterone, and dehydroepiandrosterone (DHEA) were assessed at ages 11, 13, and 15; ELS was assessed during the infancy and preschool periods. Hierarchical linear modeling revealed that cortisol-DHEA coupling patterns progressed to tight, positive coupling across adolescence. Cortisol-testosterone coupling was positive at age 11 but became more negative at ages 13 and 15. Exposure to ELS resulted in more adultlike neuroendocrine coupling patterns earlier in life than non-exposed youth; however the effect of ELS on cortisol-testosterone coupling was unique to girls. Results illustrate trajectories of neuroendocrine coupling that may be unique to adolescence. Moderation by ELS suggests that early stress exposure may prompt earlier adultlike neuroendocrine coupling, particularly within girls, which may contribute to early pubertal development.

OBJECTIVE: The objective of this study was to identify personality traits and psychiatric comorbidities associated with a lifetime history of a suicide attempt in women with bulimia nervosa (BN). METHOD: Data from two samples of women with BN (n = 204 and n = 133) were examined. Participants in both samples completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire and reported whether they had ever had a lifetime suicide attempt. Comorbid psychopathology was based on self-reported questionnaire and interview data. Univariate and multivariate logistic regression analyses were run, predicting a lifetime suicide attempt. RESULTS: Based on the Dimensional Assessment of Personality Pathology-Basic Questionnaire, identity problems were associated with a lifetime suicide attempt in both samples; cognitive dysregulation, anxiousness and insecure attachment were associated with a lifetime suicide attempt in one but not both samples. Lifetime anxiety disorder was associated with a lifetime suicide attempt in one sample, and depression was associated with a lifetime suicide attempt in both samples. Multivariate analyses revealed that only depression was uniquely associated with a lifetime suicide attempt in both samples. DISCUSSION: Although personality traits associated with aspects of emotion dysregulation were associated with a lifetime suicide attempt, depression was found to have the strongest association with a lifetime suicide attempt in two samples of women with BN. These findings suggest that depression severity may be the most important target of treatment and suicide prevention efforts in women with BN.

Although adolescence is marked by increased negative life events and internalizing problems, few studies investigate this association as an ongoing longitudinal process. Moreover, while there are considerable individual differences in the degree to which these phenomena are linked, little is known about the origins of these differences. The present study examines early life stress (ELS) exposure and early-adolescent longitudinal afternoon cortisol level as predictors of the covariation between internalizing symptoms and negative life events across high school. ELS was assessed by maternal report during infancy, and the measure of cortisol was derived from assessments at ages 11, 13, and 15 years. Life events and internalizing symptoms were assessed at ages 15, 17, and 18 years. A two-level hierarchical linear model revealed that ELS and cortisol were independent predictors of the covariation of internalizing symptoms and negative life events. Compared to those with lower levels of ELS, ELS-exposed adolescents displayed tighter covariation between internalizing symptoms and negative life events. Adolescents with lower longitudinal afternoon cortisol displayed tighter covariation between negative life events and internalizing symptoms, while those with higher cortisol demonstrated weaker covariation, partially due to increased levels of internalizing symptoms when faced with fewer negative life events.

The goal of this study was to examine associations between dimensions of emotion dysregulation and eating disorder (ED) symptoms in bulimia nervosa (BN). This investigation used baseline data from a BN treatment study that included 80 adults (90% women) with full or subthreshold BN. Participants completed the Difficulties in Emotion Regulation Scale (DERS) and the Eating Disorders Examination interview. The Eating Disorders Examination global score was significantly correlated with the DERS total score, as well as several DERS subscales: nonacceptance, impulse and strategies. Further, the DERS goals subscale was found to be uniquely associated with frequency of purging and driven exercise, although none of the subscales were associated with frequency of objective binge eating. Findings indicate that emotion dysregulation is associated with ED symptoms in BN, suggesting the utility of interventions that address emotion regulation skills deficits in the treatment of the disorder.

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.

The hypothalamic-pituitary-adrenal (HPA) axis is a primary mechanism in the allostatic process through which early life stress (ELS) contributes to disease. Studies of the influence of ELS on children's HPA axis functioning have yielded inconsistent findings. To address this issue, the present study considers multiple types of ELS (maternal depression, paternal depression, and family expressed anger), mental health symptoms, and two components of HPA functioning (traitlike and epoch-specific activity) in a long-term prospective community study of 357 children. ELS was assessed during the infancy and preschool periods; mental health symptoms and cortisol were assessed at child ages 9, 11, 13, and 15 years. A three-level hierarchical linear model addressed questions regarding the influences of ELS on HPA functioning and its covariation with mental health symptoms. ELS influenced traitlike cortisol level and slope, with both hyper- and hypoarousal evident depending on type of ELS. Further, type(s) of ELS influenced covariation of epoch-specific HPA functioning and mental health symptoms, with a tighter coupling of HPA alterations with symptom severity among children exposed previously to ELS. Results highlight the importance of examining multiple types of ELS and dynamic HPA functioning in order to capture the allostatic process unfolding across the transition into adolescence.

Daily lifestyle regularity is measured using the Social Rhythm Metric (SRM). We developed a Baby SRM, with 59 babies followed for approximately 13years. Baby SRM score at age 1 month significantly predicted the child's school (K-9, 5 time points) anxiety level (more regular=less anxious), and may be mediated through sociability and directed-attention pathways.

OBJECTIVE: Research suggests that higher childhood self-regulation (CSR) predicts lower adiposity in adolescence. However, it is unclear whether this relationship differs by sex or by baseline weight status. Thus, this study investigated these questions in a longitudinal, community-based cohort. METHODS: The cohort included 221 girls and 214 boys. At age 9, CSR was assessed via parent/teacher reports of effortful control, and childhood BMI z scores (BMIz) were calculated from staff measurements. Late-adolescent waist-to-height ratio was based on staff measurements at age 18. RESULTS: CSR has a small inverse correlation with concurrent childhood BMIz in girls, but not in boys. Prospectively, however, CSR has a small inverse association with late-adolescent weight-to-height ratio in both sexes, after adjusting for childhood BMIz and other childhood predictors. This prospective association is marginally stronger for girls with higher (vs. lower) childhood BMIz. CONCLUSIONS: CSR inversely predicts changes in adiposity across adolescence in both sexes, with some evidence that this association is stronger for girls with higher (vs. lower) childhood adiposity. However, this inverse association between CSR and adiposity may emerge earlier in girls. Future research should examine the causal status of CSR and its relationship to behaviors (e.g., diet).

OBJECTIVE: The primary aim of this study was to examine the role of affective lability in maladaptive behaviors in a sample of women who meet DSM criteria for current bulimia nervosa (BN). METHOD: Participants were administered a semistructured diagnostic interview (SCID-P) and only those who currently met criteria for BN (N = 134) were included in the analyses. All other data were collected through the use of self-report questionnaires. RESULTS: Affective lability significantly predicted the Impulsive Behavior Scale score (sr = 0.21, t = 2.64, p < .009, f(2) = 0.06) and excessive reassurance seeking (sr = 0.21, t = 2.74, p < .007, f(2) = 0.06), even when controlling for age, depressive symptoms, state and trait anxiety, and general impulsivity. DISCUSSION: The degree to which individuals with BN experience labile emotions is associated with several indicators of dysregulated behavior such that higher levels of affective lability predict a more severely dysregulated behavioral profile.

We investigated whether differences in positive and negative emotional reactivity could be found in depressed preschoolers and preschoolers at risk for later internalizing symptoms relative to nondepressed/low risk comparison groups. Observational measures of emotional reactivity, used to derive a score of the balance between anger and sadness, were obtained and analyzed in independent samples. One study utilized cross-sectional data from preschoolers (M age = 4.6 years) with a current depressive syndrome and two nondepressed comparison groups. The other study utilized longitudinal data that assessed emotional reactivity at preschool age (M age = 4.5 years) and later mental health symptoms during the transition to primary school, allowing a retrospective determination of risk. Depressed and at-risk boys displayed more anger than sadness in contrast to girls in the same groups and in contrast to no disorder/low-risk controls. This finding was detected in depressed and "at risk for internalizing" boys who were not comorbid for externalizing problems.

The psychometric properties and factor structure of the Dysfunctional Attitudes Scale were examined in a sample of 422 male and female adolescents (ages 12-17) with current major depressive disorder. The scale demonstrated high internal consistency (alpha = .93) and correlated significantly with self-report and interview-based measures of depression. Confirmatory factor analysis indicated that a correlated 2-factor model, with scales corresponding to perfectionism and need for social approval, provided a satisfactory fit to the data. The goodness-of-fit was equivalent across sexes and age groups. The findings support the use of the Dysfunctional Attitudes Scale and its subscales in the assessment of clinically depressed adolescents.

OBJECTIVE: Two studies sought to examine predictions of the Integrative Cognitive-Affective Therapy (ICAT) model, which views bulimic symptoms in terms of inter-relations between self-concept discrepancies, negative affect, and self-directed coping styles. The present results examine assessment-related predictions of this model. METHOD: Individuals with bulimic symptoms were compared to noneating disorder control participants in two studies involving central constructs of the ICAT model. RESULTS: In both studies, bulimic individuals displayed higher levels of self-discrepancy and negative self-directed styles, supporting predictions of the model. Also predicted by the model, negative mood states mediated relations between bulimic status and negative self-directed coping styles in Study 2. CONCLUSION: Assessment-related predictions of the ICAT model of bulimic symptoms were supported in two studies. These initial results support further tests of the model in longitudinal designs, contrasts of different clinical populations, and treatment-evaluation studies.

OBJECTIVE: Early research in subtyping bulimia nervosa (BN) by history of anorexia nervosa (AN) generally found more similarities than differences, but recent research and limitations of the early work suggest the need to revisit this approach. We examine differences between women with BN with and without a history of AN regarding eating pathology, personality, and childhood maltreatment. METHOD: Participants were women (aged 18-55) recruited from the community and eating disorder clinics who met DSM-IV criteria for BN; 37 had a history of AN and 101 did not. Participants completed questionnaires related to eating disorder pathology, multidimensional perfectionism, multidimensional impulsivity, and childhood maltreatment. RESULTS: Women with BN and a history of AN had higher levels of dietary restraint and purging and lower body mass indices as well as higher levels of all forms of childhood neglect and abuse. In contrast, no group differences were found for perfectionism or impulsivity dimensions. CONCLUSION: The group differences in terms of eating pathology and maltreatment have clinical implications. Further research is needed regarding if and how a history of AN among those with BN may reflect different etiological pathways and predict different outcomes.
