Brief Summary:

To demonstrate the effectiveness of an easily administered intervention (guided self help) aimed at reducing binge eating in patients undergoing bariatric surgery.

The investigators hypothesize that patients who have guided self help pre-operatively will have reduced episodes of bingeing pre-operatively compared to those having treatment as usual (bariatric surgery), which will be maintained in the post-operative period, and will be associated with improved weight loss and psychological outcomes after surgery.

Detailed Description:

Binge eating disorder (BED) is distressing and common in patients who present for treatment for obesity. Despite this, it is often undiagnosed. Patients who have bariatric surgery have improvements in their eating patterns, including binge eating. However there is variability in the degree of weight loss and post-operative complications following bariatric surgery, associated with disordered eating.

Guided self help for BED (GSH) is a treatment which, like bariatric surgery, is effective in reducing the number of binge episodes in people who binge eat. It is not known whether GSH prior to surgery, in patients undergoing bariatric surgery has any additional benefit for reducing bingeing, or improving weight loss in these patients.

Placebo Comparator: Treatment As Usual

Other: Treatment As Usual
Binge eating disordered participants receive treatment as usual in the form of bariatric surgery (i.e. no pre-operative intervention to reduce binge eating)

Primary Outcome Measures :
  1. Change in body mass index point [ Time Frame: baseline, pre-operatively, 3 month, 6 month and 1 year follow up ]

Secondary Outcome Measures :
  1. Binge episodes [ Time Frame: baseline, pre-operatively, 3 month, 6 month and 1 year follow up ]
    -Number of binge episodes per 28 days

  2. Complication or reversal of surgery [ Time Frame: 3 month, 6 month and 1 year follow up ]
    Surgical complication or reversal of bariatric surgery as per case notes

  3. Quality of life [ Time Frame: baseline, pre-operative, 3 month, 6 month and 1 year follow up ]
    Score on SF-36, IQoL-lite, Hospital anxiety and depression scale (HADS), and PANAS (positive and negative affect scale)

  4. Eating behaviour [ Time Frame: baseline, pre-operatively, 3 month, 6 month and 1 year follow up ]
    Emotional, externally driven, disinhibited, restrained eating patterns and weight and shape concerns as measured by Eating disorders examination questionnaire (EDE-Q), Dutch Eating Behaviour Questionnaire (DEBQ), Three factor eating questionnaire (TFEQ)

  5. Drug and alcohol misuse [ Time Frame: pre-operatively, baseline, 3 month, 6 month and 1 year follow up ]
    As measured by AUDIT drug and alcohol assessment tool
