Evidence-Based Psychosocial Treatments for Eating Problems and Eating Disorders / Pamela K. KEEL in Journal of Clinical Child & Adolescent Psychology, 37-1 (January-March 2008)  

Public ISBD [article]  inJournal of Clinical Child & Adolescent Psychology > 37-1 (January-March 2008) . - p.39-61 Titre : Evidence-Based Psychosocial Treatments for Eating Problems and Eating Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Pamela K. KEEL, Auteur ; Alissa HAEDT, Auteur Année de publication : 2008 Article en page(s) : p.39-61 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Eating disorders represent a significant source of psychological impairment among adolescents. However, most controlled treatment studies have focused on adult populations. This review provides a synthesis of existing data concerning the efficacy of various psychosocial interventions for eating disorders in adolescent samples. Modes of therapy examined in adolescent samples include family therapy, cognitive therapy, behavioral therapy, and cognitive behavioral therapy mostly in patients with anorexia nervosa. At this time, the evidence base is strongest for the Maudsley model of family therapy for anorexia nervosa. Evidence of efficacy for other treatments and other conditions is limited by several methodological factors including the small number of studies, failure to use appropriate control conditions or randomization procedures, and small sample sizes (i.e., fewer than 10 participants per treatment arm). Potential moderators and mediators of treatment effect are reviewed. Finally, results from adolescent studies are contrasted with those from adult studies of eating disorders treatment. Many studies of adult populations comprise late adolescent/young adult participants, suggesting that findings regarding the efficacy of cognitive behavioral therapy for bulimia nervosa in adults likely extend to older adolescent populations.

How nonshared environmental factors come to correlate with heredity / Christopher R. BEAM in Development and Psychopathology, 34-1 (February 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-1 (February 2022) . - p.321-333 Titre : How nonshared environmental factors come to correlate with heredity Type de document : Texte imprimé et/ou numérique Auteurs : Christopher R. BEAM, Auteur ; Patrizia PEZZOLI, Auteur ; Jane MENDLE, Auteur ; S. Alexandra BURT, Auteur ; Michael C. NEALE, Auteur ; Steven M. BOKER, Auteur ; Pamela K. KEEL, Auteur ; Kelly L. KLUMP, Auteur Article en page(s) : p.321-333 Langues : Anglais (eng) Mots-clés : affect  developmental behavioral genetics  gene?environment interplay  longitudinal modeling  mood Index. décimale : PER Périodiques Résumé : Conventional longitudinal behavioral genetic models estimate the relative contribution of genetic and environmental factors to stability and change of traits and behaviors. Longitudinal models rarely explain the processes that generate observed differences between genetically and socially related individuals. We propose that exchanges between individuals and their environments (i.e., phenotype?environment effects) can explain the emergence of observed differences over time. Phenotype?environment models, however, would require violation of the independence assumption of standard behavioral genetic models; that is, uncorrelated genetic and environmental factors. We review how specification of phenotype?environment effects contributes to understanding observed changes in genetic variability over time and longitudinal correlations among nonshared environmental factors. We then provide an example using 30 days of positive and negative affect scores from an all-female sample of twins. Results demonstrate that the phenotype?environment effects explain how heritability estimates fluctuate as well as how nonshared environmental factors persist over time. We discuss possible mechanisms underlying change in gene?environment correlation over time, the advantages and challenges of including gene?environment correlation in longitudinal twin models, and recommendations for future research.
