Much of the improvements found at a 5-year follow-up can be attributed to the natural outcome of the illness. Nevertheless, it was still possible to detect long-term benefits of psychological therapies completed 5 years previously.

Objective To determine whether psychological interventions have any effect on glycaemic control in people with type 1 diabetes. Design Systematic review and meta-analysis of psychological therapies to assess their effectiveness in improving glycaemic control in type 1 diabetes. Data sources Medline, PsycINFO, Embase, and Cochrane central register of controlled trials searched to September 2004. Review methods All included studies were randomised controlled trials in children (including adolescents) or adults with type 1 diabetes that evaluated the effect of a psychological therapy (counselling, cognitive behaviour therapy, family systems therapy, and psychodynamic therapy) on control of diabetes. Data were extracted on sample size, age, duration of diabetes, type of psychological therapy, its mode of delivery, and type of intervention in control group. Main outcome measures Glycaemic control measured by percentage of glycated haemoglobin and psychological distress. Pooled standardised effect sizes were calculated. Results 29 trials were eligible for the systematic review and 21 trials for the meta-analysis. In the 10 studies of children and adolescents included in the meta-analysis, the mean percentage of glycated haemoglobin was significantly reduced in those who had received a psychological intervention compared with those in the control group (pooled standardised mean difference − 0.35 (95% confidence interval − 0.66 to − 0.04), equivalent to a 0.48% (0.05% to 0.91%) absolute reduction in glycated haemoglobin. In the 11 studies in adults the pooled standardised mean difference was − 0.17 ( − 0.45 to 0.10), equivalent to 0.22% ( − 0.13% to 0.56%) absolute reduction in glycated haemoglobin. Psychological distress was significantly lower in the intervention groups in children and adolescents (pooled standardised effect size − 0.46, − 0.83 to − 0.10) but not in adults ( − 0.25, − 0.51 to 0.01). Conclusion Psychological treatments can slightly improve glycaemic control in children and adolescents with diabetes but have no effect in adults.

This paper reports the results of a randomised treatment trial of two forms of outpatient family intervention for anorexia nervosa. Forty adolescent patients with anorexia nervosa were randomly assigned to "conjoint family therapy" (CFT) or to "separated family therapy" (SFT) using a stratified design controlling for levels of critical comments using the Expressed Emotion index. The design required therapists to undertake both forms of treatment and the distinctiveness of the two therapies was ensured by separate supervisors conducting live supervision of the treatments. Measures were undertaken on admission to the study, at 3 months, at 6 months and at the end of treatment. Considerable improvement in nutritional and psychological state occurred across both treatment groups. On global measure of outcome, the two forms of therapy were associated with equivalent end of treatment results. However, for those patients with high levels of maternal criticism towards the patient, the SFT was shown to be superior to the CFT. When individual status measures were explored, there were further differences between the treatments. Symptomatic change was more marked in the SFT whereas there was considerably more psychological change in the CFT group. There were significant changes in family measures of Expressed Emotion. Critical comments between parents and patient were significantly reduced and that between parents was also diminished. Warmth between parents increased.

There is growing empirical evidence that family therapy is an effective treatment for anorexia nervosa, particularly in adolescence. This is in spite of the fact that the theoretical model from which most of the empirically based treatments are derived appears flawed. This paper provides a brief overview of the research evidence from treatment studies and studies of family functioning. It suggests that the main limitation of earlier theoretical models is their focus on aetiology rather than on an understanding of how families become organized around a potentially life‐threatening problem. An alternative conceptual model is presented, and its application to family therapy and multiple‐family therapy for adolescent anorexia nervosa is described. The treatment approach focuses on enhancing the families' own adaptive mechanism and mobilizing family strengths.

This study confirms the efficacy of family therapy for adolescent anorexia nervosa, showing that those who respond well to outpatient family intervention generally stay well. The study provides further support for avoiding the use of conjoint family meetings at least early on in treatment when raised levels of parental criticism are evident.

In the search for more effective methods of psychological treatment in anorexia nervosa, there are a number of controlled trials evaluating the efficacy of different forms of treatment. Previous studies have shown that family therapy is the superior treatment for patients with an early onset and short duration of illness. In order to assess the impact and the effective components of family therapy, we conducted a pilot trial in which consecutive referrals of anorexia nervosa patients were randomly assigned to one of two forms of family treatment: family therapy (conjoint family sessions) or family counselling (separate supportive sessions for the patient and counselling for the parents). Changes taking place within the patient and the family were evaluated at regular intervals, while within and between group comparisons were made. Although tentative, it was found that, in the short term, there were few differences in terms of symptomatic relief between the two treatment groups. © 1992 john Wiley & Sons, Inc.

The number of dropouts from a long-term treatment study of patients with anorexia nervosa (AN) and bulimia nervosa (BN) was substantial. A variety of social, clinical, parental, and treatment factors were examined for their association with early termination of treatment by the patient or the family. Parents' expressed emotion' (EE) (particularly critical comments), BN, and the type of therapy offered (family or individual) were found to interact in some manner to result in dropping out. Some other aspects of parents' EE were also examined, including a comparison of scores in parental pairs; EE was found to be influenced by social class, and there were significant associations with the patient's symptomatology and social adjustment. There was a strong relationship between mothers' and fathers' scores in parental pairs.
