Longitudinal Follow Up of Eating Disorder Treatment (L-FED)
Follow up of Young People Treated in CAEDS 2009-2014. Longitudinal Follow Up of Eating Disorder Treatment
Study Overview
Status
Detailed Description
Research Questions
- Is recovery from an eating disorder in adolescence maintained and associated with good socio-economic outcomes?
- Is poor outcome from eating disorder treatment in adolescence associated with a chronic course of illness?
- Are there factors measured during treatment that predict maintenance of outcome or relapse?
This study will use a longitudinal follow up design, contacting former patients of the National and Specialist Child and Adolescent Mental Health Service (CAMHS) Eating Disorder Service, South London and Maudsley National Health Service (NHS) Foundation Trust (CAEDS) between 1/8/2009 and 31/1/2014. These former patients are now aged 16-27. The study will thus provide the longest and largest follow up of treated adolescents to date (n = 358 over a 4-8 year follow up). Former patients will be asked a series of questions by phone/post/email about their health and socio-economic well-being since discharge from the service. This data will be analysed together with assessment and outcome data collected while they were patients of CAEDS.
Measures Data will be collected using a data collection tool developed for this project, as well as the Eating Disorders Examination Questionnaire and the Work and Social Adjustment Scale.
Data collected will comprise:
- Age now
- Employment/education
- Any help sought for eating disorder
- Any help sought for other mental health difficulties
- Current weight
- Current binge/purge symptoms
- Current general well being All data will be self-reported by participants.
Statistical power The primary analysis will be descriptive. We will recruit as many of our original treatment group as possible.
A secondary analysis will be to predict who continues to require mental health care following discharge from CAEDS. Power has been calculated following Babyak's (2004) advice for power calculation for logistic regression of 13 events (continuing mental health care needs) per variable. We have taken figures from the original audit in which 24.1% (n = 69.89) had a poor outcome to hypothesise that a similar proportion of the sample at follow up will have a poor outcome. This is a conservative estimate given the chronicity of eating disorders in adulthood and the longitudinal data of on-going mental health difficulties even in the absence of diagnosable eating disorders. In order to run a logistic regression with 5 predictor variables will require 65 cases with on-going eating disorder symptoms. This will require recruitment of the majority of the original sample assuming the % of on-going difficulties remains the same. Depending on recruitment rate we will adjust analysis accordingly, and reduce the number of predictors in the model.
Data analysis
Planned analyses:
- Descriptive analysis of key health and socio-economic outcomes for all young people who received treatment in the audited timeframe and split by treatment outcome and diagnosis for between group analysis.
- Regression analysis to identify predictors of long term outcome from clinical variables measured at baseline assessment and service discharge (including weight, mood, anxiety, eating disorder symptoms)

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Receipt of further treatment for an eating disorder in the first four years after discharge from treatment
Time Frame: From discharge from service to L-FED research assessment. Discharges between 2009 and 2014 (4-10) year follow up. Proportion of sample needing treatment in the first four years post discharge will be reported
|
Self report of whether subsequent treatment for an eating disorder has been received since discharge.
Self report of treatment received in the period between discharge and research follow up - including number and duration of outpatient treatment, hospital admission and day patient treatment.
The four year outcome is the primary outcome as it allows for the most complete dataset for follow up.

From discharge from service to L-FED research assessment. Discharges between 2009 and 2014 (4-10) year follow up. Proportion of sample needing treatment in the first four years post discharge will be reported
|
Eating Disorder Examination Questionnaire (EDEQ). Fairburn & Beglin, 1994
Time Frame: 28 days prior to L-FED research assessment
|
Self reported eating disorder symptoms.
This is a 28 item self report questionnaire which is scored using a 7 - point (0-6) rating scale.
Four subscales are derived through adding together relevant items and diving by the number of items to give a score range for each subscale of 0-6.
A total score is derived by adding together the subscales and diving by the number of subscales (ie 4) also giving a score range of 0-6.
Higher scores indicate greater impairment.

28 days prior to L-FED research assessment
|
Work and social adjustment scale (WSAS) Mundt, J. C., I. M. Marks, et al. (2002).
Time Frame: At time of L-FED research assessment. Discharges between 2009 and 2014 (4-10) year follow up. Variation in time since discharge will be stratified in analysis.
|
Self reported impact of symptoms on functioning.
This is a self report measure of the impact of illness on work and social functioning.
It is a five item questionnaire with each item scored 0-8 giving a total score range of 0-40 where high scores indicate greater impairment.
|
At time of L-FED research assessment. Discharges between 2009 and 2014 (4-10) year follow up. Variation in time since discharge will be stratified in analysis.

Secondary Outcome Measures

Receipt of treatment for an eating disorder >4 years after discharge from treatment
Time Frame: From four years post discharge from service to L-FED research assessment. Proportion
|
Self report of whether subsequent treatment for an eating disorder has been received since discharge.
Self report of treatment received in the period between discharge and research follow up - including number and duration of outpatient treatment, hospital admission and day patient treatment.
>4 years post treatment is a secondary outcome because for some participants will not have been out of treatment for more that 5 years.
We will report on the proportion of those who have been discharged for each time period who have required subsequent treatment (eg % of those discharged for 8+ years who have required further treatment)

From four years post discharge from service to L-FED research assessment. Proportion

Psychosocial wellbeing
Time Frame: At time of L-FED assessment.Discharges between 2009 and 2014 (4-10) year follow up. Variation in time since discharge will be stratified in analysis.
|
Self report questionnaire assessing function and well-being.
This is a study specific tool which measures education, employment, and subjective experience of well-being.
|
