Eating disorders were last included in the 2007 APMS; and not included in 2014. Over half (57%) of all consultation survey respondents selected eating disorders as a priority topic to add. Of respondents who reported having lived experience of mental health issues, 72% selected eating disorders as a priority topic. In focus groups support for the prioritisation of eating disorders was expressed by all types of stakeholders: representatives from across government and third sector organisations, academics and data users, and people with lived experiences indicated that eating disorders should be included in 2022. Specifically, there was interest in collecting information on:
- a broad range of disordered eating (including, but not only, anorexia nervosa and bulimia nervosa)
- the severity of symptoms
APMS 2007 used the SCOFF questionnaire, a 5-item self-reported questionnaire that picks up on general patterns of disordered eating (Morgan et al. 1999). The measure was also used on the Health Survey for England.
One suggestion was to include the Eating Disorder Examination Questionnaire (EDE-Q). The EDE-Q is a 28-item self-reported questionnaire, designed to assess the range and severity of features associated with a diagnosis of eating disorder using four subscales (restraint, eating concern, shape concern and weight concern) and a global score. It is freely available for non-commercial research use, so it is not necessary to seek permission for use. There is a 12-item short form (EDE-QS) of the EDE-Q which was developed and validated by Gideon et al. (2018). It should be noted that body dysmorphic disorder is distinct from eating disorders and not captured by the SCOFF or EDE-Q.
In the consultation survey multiple respondents suggested using the SCOFF questionnaire, in order to compare data to previous surveys. However, there was general agreement, both in focus group discussions and guided feedback interviews, that the improved measurement that would result from switching from the SCOFF to the 12-item EDE-QS would outweigh the fact that the change in method would mean it was no longer possible to look at temporal change.
Aside from the EDE-Q, survey respondents also suggested the following alternative or additional measures:
- collection of height and weight to calculate Body Mass Index (BMI), in order to compare this to results from the eating disorder responses. It was noted that self-report height and weight is often not accurately reported by survey participants, and the bias varies by gender.
- Eating Disorder-15 (15-item): this scale is usually used in clinical settings, as a session by session measure of eating disorder cognitions and behaviours
- Eating Attitudes Test (26-item): a self-completion screening measure to help determine whether a person might have an eating disorder that needs professional attention
- Eating Disorders Diagnostic Scale (22-item): a self-report scale for people aged 13-65 years old that assesses for anorexia, bulimia, and binge-eating disorder by asking the respondent about body image, eating habits, and compensatory behaviours over the last 3-6 months.
- Body Shape Questionnaire Short-form (8-item): a self-report measure of the body shape preoccupations typical of anorexia and bulimia
- Eating Disorders Quality of Life Scale (40-item): questionnaire designed to measure 12 domains of disordered eating-related quality of life. It is typically used as a treatment outcomes measure
Other than the ascertainment of eating disorder, participants did not request other eating disorder specific questions be added, except for the suggestion to include self-reported height and weight.
Social media
While the lack of questions on social media was regarded by a range of participants, including 26% of the survey respondents, as a potential topic to add for APMS, it was also recognised that social media questions could be framed in a number of ways. One recommendation was to draw on NHS Digital’s Mental Health of Children and Young People Survey, which included questions on how survey respondents felt when using social media and whether they spent more time online than intended. Others relatedly noted that questions on screen time were almost impossible to capture meaningfully, and that it was more useful to focus on behaviours and feelings while doing different activities online.
