The development and validation of the body shape questionnaire

Abstract: Concerns about body shape are common among young women in Western cultures, and, in an extreme form, they constitute a central feature of the eating disorders anorexia nervosa and bulimia nervosa. To date there has been no satisfactory measure of such concerns. A self-report instrument, the Body Shape Questionnaire (BSQ) has therefore been developed. The items that constitute this measure were derived by conducting semistructured interviews with various groups of women including patients with anorexia nervosa and bulimia nervosa. The BSQ has been administered to three samples of young women in the community as well as to a group of patients with bulimia nervosa. The concurrent and discriminant validity of the measure have been shown to be good. The BSQ provides a means of investigating the role of concerns about body shape in the development, maintenance, and treatment of anorexia nervosa and bulimia nervosa.

The impact of postnatal depression and associated adversity on early mother-infant interactions and later infant outcome.

Abstract: The impact of maternal depression and adversity on mother-infant face-to-face interactions at 2 months, and on subsequent infant cognitive development and attachment, was examined in a low-risk sample of primiparous women and their infants. The severe disturbances in mother-infant engagement characteristic of depressed groups in disadvantaged populations were not evident in the context of postpartum mood disorder in the present study. However, compared to well women, depressed mothers were less sensitively attuned to their infants, and were less affirming and more negating of infant experience. Similar difficulties in maternal interactions were also evident in the context of social and personal adversity. Disturbances in early mother-infant interactions were found to be predictive of poorer infant cognitive outcome at 18 months. Infant attachment, by contrast, was not related to the quality of 2-month interactions, but was significantly associated with the occurrence of adversity, as well as postpartum depression.

The validity of the eating disorder examination and its subscales.

Abstract: The EDE is a semistructured interview which has been developed as a measure of the specific psychopathology of anorexia nervosa and bulimia nervosa. To establish its discriminant validity it was administered to 100 patients with anorexia nervosa or bulimia nervosa and to 42 controls. The two groups differed significantly on all items. Five subscales were derived on rational grounds and evaluated on the two populations. The alpha coefficients for each subscale indicated a satisfactory degree of internal consistency. The EDE provides clinicians and research workers with a detailed and comprehensive profile of the psychopathological features of patients with eating disorders.

Controlled trial of the short- and long-term effect of psychological treatment of post-partum depression: 2. Impact on the mother-child relationship and child outcome.

Abstract: Background Postnatal depression is associated with adverse child cognitive and socio-emotional outcome. It is not known whether psychological treatment affects the quality of the mother—child relationship and child outcome. Aims To evaluate the effect of three psychological treatments on the mother—child relationship and child outcome. Method Women with post-partum depression ( n =193) were assigned randomly to routine primary care, non-directive counselling, cognitive—behavioural therapy or psychodynamic therapy. The women and their children were assessed at 4.5, 18 and 60 months post-partum. Results Indications of a positive benefit were limited. All three treatments had a significant benefit on maternal reports of early difficulties in relationships with the infants; counselling gave better infant emotional and behaviour ratings at 18 months and more sensitive early mother—infant interactions. The treatments had no significant impact on maternal management of early infant behaviour problems, security of infant—mother attachment, infant cognitive development or any child outcome at 5 years. Conclusions Early intervention was of short-term benefit to the mother—child relationship and infant behaviour problems. More-prolonged intervention may be needed.

Assessment of eating disorders: Interview or self‐report questionnaire?

Abstract: A detailed comparison was made of two methods for assessing the features of eating disorders. An investigator-based interview was compared with a self-report questionnaire based directly on that interview. A number of important discrepancies emerged. Although the two measures performed similarly with respect to the assessment of unambiguous behavioral features such as self-induced vomiting and dieting, the self-report questionnaire generated higher scores than the interview when assessing more complex features such as binge eating and concerns about shape. Both methods underestimated body weight.
