Examining the roles of emotion dysregulation and impulsivity in the relationship between psychological trauma and substance abuse among women with bulimic-spectrum pathology.

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 ( = 204) completed measures of childhood trauma, emotion dysregulation, impulsivity, and substance use.

Sex Differences in the Relationship Between Childhood Self-Regulation and Adolescent Adiposity.

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.

Comparing integrative cognitive-affective therapy and guided self-help cognitive-behavioral therapy to treat binge-eating disorder using standard and naturalistic momentary outcome measures: A randomized controlled trial.

Objective: Innovative treatments and outcome measures are needed for binge-eating disorder (BED). This randomized controlled trial compared Integrative Cognitive-Affective Therapy (ICAT-BED), an individual psychotherapy targeting momentary behavioral and emotional precipitants of binge eating, with an established cognitive-behavioral guided self-help (CBTgsh) treatment using standard and ecological momentary assessment (EMA) outcome measures.

Method: A total of 112 participants were randomized to 17 weeks of treatment (21 sessions for ICAT-BED and 10 sessions for CBTgsh).

Congruence/genuineness: A meta-analysis.

Congruence or genuineness is a relationship element with an extensive and important history within psychotherapy. Congruence is an aspect of the therapy relationship with two facets, one intrapersonal and one interpersonal. Mindful genuineness, personal awareness, and authenticity characterize the intrapersonal element.

The effects of psychotherapy treatment on outcome in bulimia nervosa: Examining indirect effects through emotion regulation, self-directed behavior, and self-discrepancy within the mediation model.

Objective: The purpose of this investigation was to examine the indirect effects of Integrative Cognitive-Affective Therapy (ICAT-BN) and Cognitive-Behavioral Therapy-Enhanced (CBT-E) on bulimia nervosa (BN) treatment outcome through three hypothesized maintenance variables: emotion regulation, self-directed behavior, and self-discrepancy.

Method: Eighty adults with BN were randomized to 21 sessions of ICAT-BN or CBT-E. A regression-based bootstrapping approach was used to test the indirect effects of treatment on outcome at end of treatment through emotion regulation and self-directed behavior measured at mid-treatment, as well as the indirect effects of treatment at follow-up through emotion regulation, self-directed behavior, and self-discrepancy measured at end of treatment.

Self-Discrepancy and Eating Disorder Symptoms Across Eating Disorder Diagnostic Groups.

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.

Association between objective and subjective binge eating and psychopathology during a psychological treatment trial for bulimic symptoms.

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.

Examining the role of self-discrepancy and self-directed style in bulimia nervosa.

Two of the primary components within Integrative Cognitive Affective Therapy (ICAT) are self-discrepancy and self-directed style. Self-discrepancy includes both actual:ideal (discrepancy between oneself and who one wishes they were) and actual:ought (discrepancy between oneself and who one believes they ought to be). Self-directed style in ICAT refers to a variety of behaviors emitted by a person toward the self including self-blaming and self-affirming.

The role of interpersonal personality traits and reassurance seeking in eating disorder symptoms and depressive symptoms among women with bulimia nervosa.

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.

Self-weighing behavior in individuals with eating disorders.

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).

Predictors and moderators of treatment outcome in a randomized clinical trial for adults with symptoms of bulimia nervosa.

Objective: This study examined predictors and moderators of outcome in 2 treatments for bulimia nervosa (BN).

Method: Eighty adults with BN symptoms at 1 of 2 sites were randomized to 21 sessions of integrative cognitive-affective therapy for BN (ICAT-BN) or enhanced cognitive behavior therapy (CBT-E). Generalized linear models examined predictors and moderators of improvements in bulimic behavior and eating disorder psychopathology at end of treatment (EOT) and 4-month follow-up (FU).

Meal patterning in the treatment of bulimia nervosa.

Objective: This study examined the relationship between changes in meal and snack consumption and eating disorder behaviors in a treatment sample of bulimic adults.

Method: Eighty adults with bulimia nervosa (BN) were randomized to one of two treatments. Meal and snack consumption, binge eating frequency, and purging behavior frequency were assessed at baseline, end-of-treatment, and at four month follow-up using the Eating Disorder Examination (EDE).

Therapeutic alliance in a randomized clinical trial for bulimia nervosa.

Objective: This study examined the temporal relation between therapeutic alliance and outcome in two treatments for bulimia nervosa (BN).

Method: Eighty adults with BN symptoms were randomized to 21 sessions of integrative cognitive-affective therapy (ICAT) or enhanced cognitive-behavioral therapy (CBT-E). Bulimic symptoms (i.

Adolescent internalizing symptoms and negative life events: the sensitizing effects of earlier life stress and cortisol.

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.

Adolescent adrenocortical activity and adiposity: differences by sex and exposure to early maternal depression.

Prior research has linked either basal cortisol levels or stress-induced cortisol responses to adiposity; however, it remains to be determined whether these distinct cortisol measures exert joint or independent effects. Further, it is unclear how they interact with individual and environmental characteristics to predict adiposity. The present study aims to address whether morning cortisol levels and cortisol responses to a psychosocial stressor independently and/or interactively influence body mass index (BMI) in 218 adolescents (117 female) participating in a longitudinal community study, and whether associations are moderated by sex and exposure to early maternal depression.

Associations of child insomnia, sleep movement, and their persistence with mental health symptoms in childhood and adolescence.

Study Objectives: To examine the patterns of insomnia and sleep-related movement from ages 4.5 to 9 years, their concurrent associations with mental health symptoms in childhood, and the longitudinal associations of sleep-problem persistence with mental health symptoms at ages 9 and 18 years.

Design: A 14-year prospective follow-up study.

Dimensions of emotion dysregulation in bulimia nervosa.

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.

Hard exercise, affect lability, and personality among individuals with bulimia nervosa.

The current study explores the personality traits of compulsivity (e.g., sense of orderliness and duty to perform tasks completely) and restricted expression (e.

Neuroendocrine coupling across adolescence and the longitudinal influence of early life stress.

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.

Concurrent and longitudinal associations between diurnal cortisol and body mass index across adolescence.

Purpose: Childhood and adolescent obesity have reached epidemic levels; however, little is known about the psychobiological underpinnings of obesity in youth and whether these differ from the mechanisms identified in adults. The current study examines concurrent (i.e.

Subjective and objective binge eating in relation to eating disorder symptomatology, negative affect, and personality dimensions.

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.
