The study explored lifetime prevalence of non-suicidal self-injury (NSSI) in female and male individuals with eating disorders (ED) and compared ED symptoms, general psychopathology and personality traits across individuals with and without a history of NSSI. The incremental discriminative capacity of gender on the manifestation of lifetime NSSI was also studied. A total sample of 1649 consecutively admitted ED patients (1515 women and 134 men) participated in the current study [339 ED + NSSI (ED with NSSI) and 1310 ED − NSSI (ED without NSSI)]. Specific self-report measures were included and other clinical and psychopathological indices. The observed lifetime prevalence of NSSI was 20.6% (20.9% in women and 17.2% in men). NSSI was not associated with ED type or gender. However, ED + NSSI patients exhibited more impulsive behaviour, substance-abuse disorders and additional impulse-control disorders, were younger and had more previous treatments. Age was shown to affect the presentation of NSSI. Additionally, ED + NSSI patients exhibited more severe ED and general psychopathological symptoms and had more dysfunctional personality traits when compared with ED − NSSI. ED + NSSI was found to be positively associated with harm avoidance and self-transcendence but negatively with reward dependence, self-directedness and cooperativeness. Thus, the variables with stronger capacity to identify the presence of ED + NSSI were younger age, harm avoidance, self-directedness and self-transcendence. A lack of association between sex and ED subtype with the presence of NSSI was observed. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Evidence associates anorexia nervosa (AN) with epigenetic alterations that could contribute to illness risk or entrenchment. We investigated the extent to which AN is associated with a distinct methylation profile compared to that seen in normal-eater women. Method Genome-wide methylation profiles, obtained using DNA from whole blood, were determined in 29 women currently ill with AN (10 with AN-restrictive type, 19 with AN-binge/purge type) and 15 normal-weight, normal-eater control women, using 450 K Illumina bead arrays. Results Regardless of type, AN patients showed higher and less-variable global methylation patterns than controls. False Discovery Rate corrected comparisons identified 14 probes that were hypermethylated in women with AN relative to levels obtained in normal-eater controls, representing genes thought to be associated with histone acetylation, RNA modification, cholesterol storage and lipid transport, and dopamine and glutamate signaling. Age of onset was significantly associated with differential methylation in gene pathways involved in development of the brain and spinal cord, while chronicity of illness was significantly linked to differential methylation in pathways involved with synaptogenesis, neurocognitive deficits, anxiety, altered social functioning, and bowel, kidney, liver and immune function. Discussion Although pre-existing differences cannot be ruled out, our findings are consistent with the idea of secondary alterations in methylation at genomic regions pertaining to social-emotional impairments and physical sequelae that are commonly seen in AN patients. Further investigation is needed to establish the clinical relevance of the affected genes in AN, and, importantly, reversibility of effects observed with nutritional rehabilitation and treatment. © 2015 Wiley Periodicals, Inc.

ABSTRACT Objective We examined differences in treatment outcome associated with a 'self-directed'- versus 'external-incentive'-based day treatment protocol for individuals with eating disorders (EDs) with below normal body mass index. The self-directed protocol recommended a weekly 500 g weight gain, but allowed participants freedom to gain weight at their own rate; the 'external-incentive' protocol required a minimum weight gain of 500 g/week as a requirement for staying in the program. Method Weight outcome was available for 49 individuals who were treated with the recommended weight gain protocol, and 40 individuals who were treated with the required weight gain protocol. Results Post-treatment weight was significantly higher in patients treated in the required weight gain protocol compared to those treated in the recommended weight gain protocol. All patients, regardless of which program they completed, showed improvements in the measures of eating-disorder and comorbid-psychiatric symptoms. Discussion This study demonstrated the benefits of an alteration in protocol that required no additional financial or human resources. Further studies are needed to validate the effectiveness of various day treatment protocol parameters. © 2014 Wiley Periodicals, Inc. (Int J Eat Disord 2014; 47:500-506) [ABSTRACT FROM AUTHOR]

Individuals with eating disorders are said to be highly ambivalent towards change and thus have difficulty maintaining a commitment to, and motivation for, treatment. Self-Determination Theory postulates that autonomous motivation for therapy exists when individuals view their participation as freely chosen. Objective The present study was designed to ascertain whether or not autonomous motivation was associated with treatment response in individuals with bulimia-spectrum eating disorders (BSED). Method One hundred and fifty-five women with DSM-IV-TR BSED participated in multimodal group therapy and completed measures to assess motivation, eating and comorbid symptoms. Results Hierarchical multiple regression analyses demonstrated that higher levels of autonomous motivation at pretreatment predicted lower post-treatment scores on measures of eating preoccupations (shape, weight and eating concerns), binge eating, anxiety/depression, relationship to self and others and impulsivity. Discussion These results indicate that autonomous motivation may be an important predictor of outcome following treatment for BSED.

Objective: We sought to estimate prevalences of childhood emotional abuse (CEA) in bulimic and normal-eater control groups, and to replicate previous findings linking CEA to severity of eating symptoms in BN. We also examined potential mediators of the link between CEA and disordered eating. Method: Women diagnosed with a bulimic disorder ( n = 176) and normal-eater women ( n = 139) were assessed for childhood traumata, eating-disorder (ED) symptoms and psychopathological characteristics (ineffectiveness, perfectionism, depression, and affective instability) thought to be potential mediators of interest. Results: CEA was more prevalent in the bulimic than in the nonbulimic group, and predicted severity of some eating-symptom indices. Ineffectiveness and affective instability both mediated relationships between CEA and selected ED symptoms. Discussion: We found CEA to predict eating pathology through mediating effects of ineffectiveness and affective instability. CEA might influence severity of ED symptoms by impacting an individual's self-esteem and capacity for affect regulation. © 2011 by Wiley Periodicals, Inc.
