Research summary
Obesity has been highlighted as a risk factor for preventable diseases; weight loss surgery (WLS) is a recommended treatment for individuals with a BMI above 40. Clinical interview is the main method of psychological assessment for WLS however this can be costly and time consuming. Despite commonly identified risk factors (alcohol and drug use, suicidality), there is currently no clinical tool that is consistently used to evaluate these. A tool assessing psychological risk in WLS candidates could streamline assessments and help to provide a more efficient bariatric service. Further, research shows variability in weight-loss maintenance post-WLS which can be attributed to poor self-regulation of eating behaviour. A combined gratitude and implementation intention intervention could improve self-regulation of eating behaviour and aid in weight-loss maintenance.
Study aims: To test the detection rate, and predictive value, of a screening tool for WLS. To test the utility of a gratitude-intention intervention for improving weight-loss maintenance post-WLS.
Candidates undergoing assessment for WLS at St Richards Hospital, Chichester, will be invited to participate by the bariatric service. Data will be collected online and via post.The study recruitment will be conducted in three phases using retrospective and prospective data. Participants in Phase I (retrospective) and II (prospective) will be asked to complete a short questionnaire at 12 months post-WLS to be matched with their pre-operative assessment data. In Phase III, participants from Phases I and II who have provided an email address will be contacted at 18 months post-WLS and randomly allocated into two conditions: non-treatment control the or combined gratitude-intention intervention. Participants in the intervention will be asked to complete a short online gratitude-intention implementation task twice weekly for four weeks.
Outcome measures: Weight loss (BMI), binge eating, health status, alcohol and drug use, suicidality, HbA1c, self-esteem, mood, gratitude, perceived social support, life satisfaction, and social comparison.
