Impulsivity and compulsivity in anorexia and bulimia nervosa: A systematic review.

This study aimed to systematically appraise cross-sectional research that compared the cognitive performance of individuals in the acute phase of BN and/or AN to HCs on measures of impulsivity and compulsivity. The results of the systematic review showed support for the trans-diagnostic approach to eating disorders. There was no strong evidence to support the characterisation of AN as high in compulsivity (and low in impulsivity), nor to support the characterisation of BN as high in impulsivity (and low in compulsivity). There appeared to be mixed findings for both impulsivity and compulsivity across AN and BN. Results were highly variable due to the heterogeneous tasks used, and lack of replication across studies. There was no consensus amongst the included studies on the most appropriate task and/or outcome measures that should be used to study the constructs of impulsivity and compulsivity.

Pre-treatment patient characteristics as predictors of drop-out and treatment outcome in individual and family therapy for adolescents and adults with anorexia nervosa: A systematic review and meta-analysis.

Understanding variables predicting drop-out or unfavourable outcome following treatment for anorexia nervosa (AN) may help to improve upon intervention efforts. However, the current literature has demonstrated sparse and inconsistent significant findings. The current systematic review and meta-analysis summarised the evidence base examining baseline predictors of drop-out and outcome in AN treatment. A literature search was conducted to identify research investigating predictors of drop-out and outcome in individuals treated for AN. Four online databases were searched, and predictors were organised by category and dependent variable (outcome versus drop-out). 27 studies were included. Lower motivation, lower BMI, and having the binge-purge subtype of AN predicted drop-out. Greater ED pathology and poorer motivation predicted poorer outcome. Clinical recommendations include taking particular care during assessment stages to identify patients at risk of drop-out and/or poor outcome based on their clinical profile and level of motivation for recovery. At-risk patients should be receiving tailored treatment to enhance engagement and reduce risk of drop-out. In conclusion, there's some evidence that motivation, BMI, subtype, and ED pathology predicts drop-out and/or outcome in individual and family-based therapy for AN amongst adolescents and adults; however, research incorporating carefully designed multi-site studies is required to further examine these findings.

The Egosyntonic Nature of Anorexia: An Impediment to Recovery in Anorexia Nervosa Treatment.

A serious problem faced by clinicians treating anorexia nervosa is the egosyntonic nature of the illness, wherein individuals with anorexia nervosa value their disorder, thereby hindering motivation for recovery and engagement with treatment. The objective of this review article is to elucidate the nature of egosyntonicity in anorexia nervosa, reviewing both qualitative and quantitative research pertaining to this topic, and, importantly, to present methods to overcome this impediment to recovery in anorexia nervosa treatment. The authors elucidate functions of anorexia nervosa for patients, both within psychological and social spheres, as well as highlight the detrimental effect of egosyntonicity in terms of illness severity and motivation for recovery. The final part of the paper contains suggestions as to methods of bypassing pitfalls linked with the influence of the egosyntonic nature of anorexia nervosa within a treatment setting, as well as an examination of three current treatments (enhanced cognitive-behavioral therapy for eating disorders, Maudsley Model of Anorexia Nervosa Treatment for Adults, and Specialist Supportive Clinical Management) in terms of the degree to which they target egosyntonicity.

Maternal Rejection and Idealized Value of Appearance: Exploring the Origins of Body Dysmorphic Concerns Among Young Adults.

Body dysmorphic disorder is a clinical disorder characterized by a preoccupation with an imagined or exaggerated defect in one's appearance (American Psychological Association, 2013), causing impaired functioning. Cognitive-behavioral models of body dysmorphic disorder have been proposed, whereby social anxiety and parental rejection may be predisposing factors, whereas maladaptive cognitive biases, such as appraisals of rejection, may serve as maintenance factors. The primary aim of this study was to test the role that perceived parental rejection in childhood may play in understanding the development of body dysmorphic symptoms. Furthermore, this study examined whether idealized values of appearance act as a mediator between perceived maternal rejection and body dysmorphic symptoms. The sample comprised 239 Australian undergraduate psychology students. Social anxiety, appearance-based rejection sensitivity, maternal rejection, and idealized values of appearance uniquely predicted body dysmorphic symptoms. Furthermore, the relationship between maternal rejection and body dysmorphic symptoms was partially mediated by idealized values of appearance. Findings support cognitive-behavioral models of body dysmorphic disorder.
