The Chronic Pain Grade questionnaire has been proposed as an interview-administered, multi-dimensional measure of chronic pain severity in selected populations with chronic pain in the United States of America. It has not previously been tested in the United Kingdom, in self-completion form or in an unselected general population. We undertook a postal survey to assess its reliability, validity and acceptability in these circumstances, using a general practice population in Scotland, with a practice population of 11202 patients. A random sample of 400 patients aged over 18 was drawn, stratified for age, gender and receipt or non-receipt of regular prescriptions for pain-relieving medication. The dimensions and sub-scales of the Chronic Pain Grade were compared with the SF-36 general health questionnaire and questions relating to duration of any pain and attempts to seek treatment for this. The methodological approach proposed by Streiner and Norman (1989) was used to assess validity and reliability. A response rate of 76% was achieved. Cronbach's alpha was > 0.9 and item-total correlations were all high, indicating good internal consistency and reliability. Validity was confirmed by psychometric testing, including confirmatory factor analysis. Good correlations with comparable dimensions of the SF-36 general health questionnaire confirmed convergent validity. Construct validity was confirmed by testing scores against duration of pain and treatment sought for pain. We concluded that the Chronic Pain Grade questionnaire is a useful, reliable and valid measure of severity of chronic pain. It translates well into UK English and is acceptable in general population postal research.

iCBT with e-mail support is efficacious in students with bulimic disorders and has lasting effects.

Little is known about what determines uptake and acceptability of internet-based treatments in eating disorders, and users' experience with such treatments. We investigated these factors in participants of a randomized controlled trial of an internet-based cognitive- behavioural treatment (iCBT) package (Overcoming bulimia online). Nine participants were interviewed using purposive sampling. The content of interviews were analyzed using thematic analysis. Additionally, participants received questionnaires about their impressions of iCBT. Participants talked about their experience of using iCBT, its impact and compared it to other treatments. Questionnaire responses echoed themes identified in the interviews. iCBT was received positively as a way of fitting treatment into busy lives. Comments on the layout of some of the package content and the practitioner support offered were identified as areas that could be modified or improved.

The concept of unmet physical and psychological needs can be used as an underlying integrative framework for understanding and working with this patient group, alongside any treatment model. A functional understanding of the neuro-biological, physiological and psychological mechanisms involved in anorexia nervosa can help patients reduce self-criticism and shame. Fears about being or becoming fat, greedy, needy, selfish and unacceptable ('Feared Self') drive over-compensatory self-depriving behaviour ('Anorexic Self'). Psychological treatment for anorexia nervosa should emphasize a focus on feelings and fostering experiences of acceptance and trust. Treatment for patients with anorexia nervosa needs to be longer than current clinical practice.
