Binge Eating, Binge-Eating Disorder
Conditions
Brief summary
The purpose of the present pilot study is to evaluate the feasibility, acceptability and likely effectiveness of an evidence-based guided self-help intervention for binge eating and related disordered over-eating in those unable to access clinician provided treatments. If feasible, acceptable and likely to be effective, such interventions could be made available more widely as an early intervention to those in need. Such interventions have the potential to improve quality of life by removing or ameliorating symptoms that impair psychological and social functioning. Eligible participants will receive the guided self-help intervention - an evidence-based self help program in the form of a self-help book plus telephone support and encouragement to follow the program provided by specially trained help-line volunteers. Support completing the self-help program will be provided over a period of 4 months and participants will be followed up for a year after completion of the intervention. Participants will be asked to complete brief online assessments before starting the program, at the end of 4 months when they complete the program and at 6 month and 12 month follow up.

| Feasibility of providing intervention-completion Participants' ratings of satisfaction with the intervention | 16 weeks | Percentage of eligible participants who complete intervention |
| Ratings of Acceptability of intervention to participants | At Baseline - before start of intervention | Participants' ratings of suitability of intervention on visual analogue scale with anchors of strongly agree to strongly disagree |

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Likely effectiveness - impairment due to eating difficulties | Week 0 (baseline) and week 16 (end of intervention) | Change in impairment due to eating difficulties score on well validated self report measure the Clinical Impairment assessment (CIA). Possible scores range from 0 (no impairment ) to 48 (highest level of impairment). |
| Likely effectiveness - depression | Week 0 and week 16 (end of intervention) | Change in depression scores on well validated self report measure, Patient Health Questionnaire (PHQ 9). Possible scores 0 (no depressed mood) to 27 (highest levels of depressive symptoms. |
| Likely effectiveness -Eating difficulties | week 0 (baseline) and week 16 (end of intervention) | Change in global score on a well validated self-report measure of eating disorder attitudes and behavior-Eating Disorder Questionnaire.
