Psychological variables impacting weight gain rapidity in adolescents hospitalized for eating disorders

Emotion regulation as a transdiagnostic construct across the spectrum of disordered eating in adolescents: A systematic review

OBJECTIVE

This systematic review aimed to understand the role of emotion regulation (ER) across the spectrum of disordered eating behaviors and attitudes in adolescents.

METHOD

A literature search was conducted using the PubMed, Scopus, and Web of Science databases, and 8381 articles were extracted. After removing duplicates and screening, data from 50 articles involving 31,591 participants from 18 countries were included.

RESULTS

Consistent associations between difficulties in ER/maladaptive ER and overeating (but not restrictive) behaviors/attitudes were found among adolescents without an eating disorder diagnosis. In contrast, in adolescents with eating disorders, ER difficulties were associated with restrictive-, compensatory- and overeating-type eating disorders. More difficulties in ER were found among adolescents with eating disorder diagnoses (i.e., anorexia nervosa, bulimia nervosa, or binge eating disorder) than among their healthy/normal-weight peers. Nonetheless, difficulties in ER abilities and in the implementation of ER strategies were greater in adolescents with anorexia nervosa or bulimia nervosa than in adolescents with binge eating disorder. Finally, concerning the role of adaptive ER, although fewer adaptive ER strategies were consistently found in adolescents with a diagnosis of anorexia nervosa than in healthy controls, the results in community samples were less consistent.

DISCUSSION

Overall, ER was associated with disordered eating behaviors/attitudes and eating disorder diagnoses, supporting the transdiagnostic role of ER in the spectrum of eating psychopathology. Fewer consistent findings were found across the weight spectrum, specifically at the higher end (overweight/obesity). These results highlighted the role of different ER abilities and strategies and the relevance of maladaptive (vs. adaptive) ER in understanding disordered eating. The findings also set the context for developing specific ER-based interventions across the spectrum of disordered eating behaviors and attitudes.

The relationship between perfectionism and eating-related symptoms in adolescents: A systematic review

The clinical significance of two major aspects of perfectionism, perfectionistic strivings (PS) and perfectionistic concerns (PC), in eating disorders (EDs) symptoms was well-established among adults. However, no systematic review has assessed evidence examining associations between both unidimensional and multidimensional perfectionism and EDs in early and middle adolescence. For this aim, three online databases (PsycINFO, Medline and PsycArticle) were searched for articles published until January 2019, and observational studies were considered. Study quality was systematically appraised, and results were summarized using a narrative synthesis approach. Fifty-one cross-sectional and 28 longitudinal studies were included. Most studies supported the relationship between perfectionism and EDs, with the majority adopting a unidimensional approach for assessing perfectionism. Among studies that employed multidimensional measures of perfectionism, the majority (n = 11) of evidence supported the relationship between eating symptoms and PC, while fewer (n = 5) studies provided significant unique associations with PS. These findings are consistent with the body of research suggesting the strength of the relationship between PC and EDs was greater than between PS and EDs. It was recommended that preventive interventions should be primarily focused on reducing self-critical perfectionism, since it resulted to be the most relevant perfectionistic dimension in the development of eating symptoms in adolescents.

Predicting a comprehensive operationalization of eating disorder recovery: Examining self-concept, personality, and negative affect

OBJECTIVE

Our goal was to examine potential predictors of a comprehensive operationalization of eating disorder recovery, characterized by physical, behavioral, and cognitive recovery, focusing on constructs related to self-concept, personality, and negative affect.

METHOD

Participants were women with a history of an eating disorder who provided data via survey and interview at two time points separated by about 7-8 years and who met criteria for an eating disorder diagnosis at baseline (N = 36).

RESULTS

Logistic regression models revealed that self-esteem was a significant predictor of recovery status (OR = 1.12, p = .039) such that individuals with higher self-esteem at baseline demonstrated significantly greater odds of being in full recovery at follow-up. However, when self-esteem was considered in a set along with baseline imposter phenomenon and anxiety, no single construct emerged as a significant unique predictor of recovery in logistic regression analyses.

DISCUSSION

These results highlight the potential importance of self-esteem in relation to recovery, with clinical implications related to bolstering self-esteem as part of eating disorder treatment. Future research should continue to explore predictors using a comprehensive operationalization of eating disorder recovery in larger, more diverse samples to optimally identify factors associated with achieving recovery.

Perfectionism is associated with higher eating disorder symptoms and lower remission in children and adolescents diagnosed with eating disorders

OBJECTIVE

The link between perfectionism and eating disorders is well established in adults, however little research has been conducted in children and adolescents. The aim was to examine if perfectionism was a predictor of eating disorder symptoms at intake assessment, and 6 and 12 month review.

METHOD

There were 175 children and adolescents aged 10-17 years (M = 14.47 years, SD = 1.31) who were assessed using the Eating Disorders Inventory-3 perfectionism subscale and the child adapted Eating Disorders Examination at intake, 6 and 12 months review.

RESULTS

There was a significant association between perfectionism and symptoms of eating disorders at intake assessment and at 6 and 12 month review. Higher perfectionism at intake predicted a lower likelihood of remission at 12 months.

DISCUSSION

The findings suggest that similar to adult samples, perfectionism is significantly associated with eating disorder symptoms in children and adolescents. Further research is required to examine the impact of perfectionism on eating disorder symptoms in longitudinal research with children and adolescents with eating disorders.

Review: Assessment, development, and treatment of childhood perfectionism: a systematic review

BACKGROUND

In the adult literature, perfectionism has been linked with psychopathology and poor treatment outcomes, leading to perfectionism-focussed therapies. The child and adolescent perfectionism literature is comparatively sparse.

METHOD

A systematic search of five electronic databases (Web of Knowledge, APA PsycNET, PubMed, ERIC/ProQuest, and Scopus) was conducted to identify studies of perfectionism in children and adolescents, in the context of psychopathology.

RESULTS

The search identified 133 studies, 84 of which discussed perfectionism as a correlate of mental health problems. These studies were briefly synthesised, with the systematic review focussing on evaluating papers on the development (n = 23), assessment (n = 19), and treatment (n = 7) of perfectionism.

CONCLUSION

Treatment studies did not reflect the phenomenology of perfectionism found in this review.
