We examined change in defensive functioning following group psychodynamic-interpersonal psychotherapy (GPIP) for binge-eating disorder (BED) compared to a waitlist control. We hypothesized that defensive functioning will improve to a greater extent at posttreatment for those in GPIP compared with those in a waitlist control condition. Participants were women with BED assigned to GPIP ( = 131) or a waitlist control ( = 44) condition in a quasi-experimental design.

We used an actor-partner interdependence model (APIM) to study the association between the individual group member and other group therapy members' defensive functioning on an individual group member's treatment outcome. We hypothesized that (a) more adaptive individual defensive functioning at pretreatment will be significantly related to better treatment outcomes (i.e.

Objective: We investigated the quality of randomized controlled trials (RCTs) that included direct comparisons of psychotherapy for adults with an eating disorder (ED).

Method: Thirty-five direct comparison RCTs of psychotherapy for adults diagnosed with an ED were rated using the Randomized Controlled Trials Psychotherapy Quality Rating Scale (RCT-PQRS).

Results: The mean total RCT-PQRS score (mean = 28.

We conducted a meta-analysis of randomized controlled trials (RCTs) of bona fide psychotherapy for adults with eating disorders (EDs). Thirty-five RCTs with 54 direct comparisons were included. The majority of RCTs included participants with bulimia nervosa and/or binge-ED, while only two RCTs included participants with anorexia nervosa, and three RCTs included participants with an ED not otherwise specified.

Background: A stepped care approach involves patients first receiving low-intensity treatment followed by higher intensity treatment. This two-step randomized controlled trial investigated the efficacy of a sequential stepped care approach for the psychological treatment of binge-eating disorder (BED).

Methods: In the first step, all participants with BED (n = 135) received unguided self-help (USH) based on a cognitive-behavioral therapy model.

Objective: In the current meta-analysis, we review the effect of group psychotherapy compared to both wait-list controls and other active treatments for adults with eating disorders (EDs).

Method: Twenty-seven randomized controlled trials (RCTs) that provide direct comparisons with a total of 1,853 participants were included.

Results: Group psychotherapy is significantly more effective than wait-list controls at achieving abstinence rates of binge eating and/or purging (RR = 5.

Insecure and unresolved/disorganized attachment states of mind may impact affect regulation and interpersonal functioning that contribute to binge eating in women with binge-eating disorder (BED). Group psychological treatment may facilitate changes from insecure to secure and from unresolved-disorganized to non-unresolved/disorganized attachment states of mind. This study used attachment theory to understand better the psychopathology of BED and co-morbid overweight status and to understand better the treatment response of patients with BED who receive group psychotherapy.

Coherence of mind and reflective functioning may impact negative affect and interpersonal functioning over and above the effects of symptoms of depression and interpersonal problems that contribute to symptoms of binge-eating disorder (BED) and overweight/obesity. Matched samples of overweight women with BED and overweight and normal weight women without BED completed the Adult Attachment Interview, a measure of depressive symptoms, and a measure of interpersonal problems. Greater symptoms of depression distinguished women with BED from the matched comparison samples.

Objective: To examine the role of attachment dimensions, including coherence of mind and reflective functioning, in developing and maintaining binge-eating disorder (BED) and in determining group psychotherapy outcomes for women with BED. We hypothesize that higher pre-treatment attachment dimension scores will predict better treatment outcomes for women with BED and will increase at follow-up.

Method: Women with BED attended 16 sessions of group therapy and completed the Adult Attachment Interview (AAI) at pre-treatment.

We evaluated an attachment theory model in which mother and father care were hypothesized to be indirectly related to body dissatisfaction mediated by attachment anxiety and media internalization. Participants were 232 women diagnosed with an eating disorder who completed a retrospective measure of parental bonds, and measures of attachment anxiety, media internalization, and body image. Mother care was negatively associated with body dissatisfaction, suggesting that recollection of mothers as less caring was directly related to poorer body image.

Objective: This study examined change in defensive mechanism functioning during group psychodynamic interpersonal psychotherapy (GPIP) for women with binge-eating disorder (BED).

Procedure: Women with BED (N = 85) received 16 weeks of GPIP. Five group therapy sessions (sessions 1, 3, 8, 12, and 16) from each of the 12 groups were video recorded and transcribed.

Objective: Given the recent publication of several large trials and systematic reviews, we undertook a study of the current management of bronchiolitis in Canadian pediatric emergency departments (EDs) and explored physicians' rationale for their treatment decisions. The overarching purpose of this study was to assist in planning a future trial of combined epinephrine and dexamethasone for bronchiolitis.

Methods: Physicians in the Pediatric Emergency Research Canada (PERC) database received an 18-item electronic survey.
