Assessing clinician competence in the delivery of cognitive-behavioural therapy for eating disorders: development of the Cognitive-Behavioural Therapy Scale for Eating Disorders (CBTS-ED).

Evidence-based cognitive-behaviour therapy for eating disorders (CBT-ED) differs from other forms of CBT for psychological disorders, making existing generic CBT measures of therapist competence inadequate for evaluating CBT-ED. This study developed and piloted the reliability of a novel measure of therapist competence in this domain-the Cognitive Behaviour Therapy Scale for Eating Disorders (CBTS-ED). Initially, a team of CBT-ED experts developed a 26-item measure, with general (i.e. present in every session) and specific (context- or case-dependent) items. To determine statistical properties of the measure, nine CBT-ED experts and eight non-experts independently observed six role-played mock CBT-ED therapy sessions, rating the therapists' performance using the CBTS-ED. The inter-item consistency (Cronbach's alpha and McDonald's omega) and inter-rater reliability (ICC) were assessed, as appropriate to the clustering of the items. The CBTS-ED demonstrated good internal consistency and moderate/good inter-rater reliability for the general items, at least comparable to existing generic CBT scales in other domains. An updated version is proposed, where five of the 16 "specific" items are reallocated to the general group. These preliminary results suggest that the CBTS-ED can be used effectively across both expert and non-expert raters, though less experienced raters might benefit from additional training in its use.

Daptomycin selects for genetic and phenotypic adaptations leading to antibiotic tolerance in MRSA.

Objectives: Daptomycin non-susceptibility in Staphylococcus aureus can emerge via the accumulation of single or multiple mutations, each resulting in a slight increase in the daptomycin MIC. The daptomycin-non-susceptible phenotype may include other features such as daptomycin tolerance. This study identifies S. aureus genomic regions that frequently develop mutations following prolonged daptomycin exposure but have not been previously associated with daptomycin non-susceptibility. Methods: Sequence variations in the same eight loci independently observed following 28 day parallel serial passages of S. aureus J01 in daptomycin were introduced in isolation into S. aureus J01. MICs were determined by microbroth dilution. Daptomycin killing and tolerance were determined by kill curve analysis. Results: Single mutations in snoF, hmp1, sspA, rimP, hepT, rsh, map1 and amaP had only a modest impact on the daptomycin MIC (≤2-fold). In contrast, individual mutation in several of these regions resulted in pronounced changes to daptomycin tolerance. Conclusions: This study demonstrates that less characterized mutations in S. aureus following daptomycin exposure do not result in significant daptomycin susceptibility changes, but rather allow for enhanced survival characteristics during treatment. This sheds new light on genetic adaptations that may play a role in persistent infection. Further studies are needed to elucidate the prevalence of these mutations in clinical isolates.

Metacognition in patients with anorexia nervosa, dieting and non-dieting women: a preliminary study.

OBJECTIVE: To explore metacognition in women with anorexia nervosa (AN), dieting and non-dieting women. METHOD: A cross-sectional study between groups design compared women with AN (n = 15), normal dieters (n = 17) and non-dieters (n = 18). A semi-structured interview was used to explore presence and content of explicit metacognitions and use of metacognitive control strategies. RESULTS: Explicit metacognitions and metacognitive control strategies were present in all three groups of women. There were group differences in amount and function of metacognitive activity and trends in the qualitative data suggested participants with AN believed that their thoughts were abnormal and uncontrollable. They used six metacognitive strategies more than control groups and were less successful at using thought re-appraisal and attending to body and others. Half of participants with AN reported using these strategies to deliberately make themselves feel worse. DISCUSSION: It is suggested that metacognitive activity may play a role in the maintenance of AN, particularly in reinforcing negative self-evaluations.

The relationship of disordered eating habits and attitudes to clinical outcomes in young adult females with type 1 diabetes.

OBJECTIVE: To describe the clinical outcomes of adolescent and young adult female subjects with type 1 diabetes in relation to the disturbance of eating habits and attitudes over 8-12 years. RESEARCH DESIGN AND METHODS: Patients were recruited from the registers of pediatric and young adult diabetes clinics (including nonattenders) and interviewed in the community. A total of 87 patients were assessed at baseline (aged 11-25 years), and 63 (72%) were reinterviewed after 8-12 years (aged 20-38 years). Eating habits and attitudes were assessed by a semistructured research diagnostic interview (Eating Disorder Examination). RESULTS: Clinical eating disorders ascertained from the interview and/or case note review at baseline or follow-up were found in 13 subjects (14.9% [95% CI 8.2-24.2]), and an additional 7 subjects had evidence of binging or purging, bringing the total affected to 26%. Insulin misuse for weight control was reported by 31 (35.6% [25.7-46.6]) subjects. Overall outcome was poor; serious microvascular complications were common and mortality was high. There were significant relationships between disordered eating habits, insulin misuse, and microvascular complications. CONCLUSIONS: Although the cross-sectional prevalence of clinical eating disorders in young women with diabetes is modest, the cumulative incidence of eating problems continues to increase after young adulthood, and this is strongly associated with poor physical health outcomes. The combination of an eating disorder and diabetes puts patients at high risk of mortality and morbidity. Better methods of detection and management are needed.

Parental bonding and eating disorder symptoms in adolescents: the meditating role of core beliefs.

This study aimed to investigate the mediating role of early maladaptive schemas in the relationship between parental bonding and eating disorder symptoms in a group of female adolescents. Three hundred and sixty-seven female adolescents completed the Parental Bonding instrument [PBI; Brit. J. Med. Psychol. 52 (1979) 1-10], the Young Schema Questionnaire short version [YSQ; Young, J. E. (1998). The Young Schema Questionnaire: Short form. Available at ], and the Eating Attitudes Test [EAT; Psychol. Med. 9 (1979) 273-279]. Two underlying schemas, defectiveness/shame and dependence/incompetence, were perfect mediators in the relationship between parental bonding and eating disorder symptoms. Schemas relating to both shame and dependency may be important in determining the effect that parental bonding has on eating disorder symptoms in a sample of female adolescent schoolgirls.
