Manualised Cognitive Remediation Therapy for adult obesity: study protocol for a randomised controlled trial.

Raman J, Hay P, Smith E - Trials (2014)

Bottom Line: An intervention that could help reduce these deficits and in turn help weight loss maintenance is Cognitive Remediation Therapy for Obesity (CRT-O).We aim to examine the efficacy of manualised CRT-O, which is intended to improve executive function, enhance reflective practice and help weight loss maintenance.Measurement points will be at baseline, post CRT-O (or 4 to 6 weeks after BWLT for the no-treatment control), 3 months post treatment and 1 year post treatment.

ABSTRACT

Background: Research has shown that obese individuals have cognitive deficiencies in executive function, leading to poor planning and impulse control, and decision-making difficulties. An intervention that could help reduce these deficits and in turn help weight loss maintenance is Cognitive Remediation Therapy for Obesity (CRT-O). We aim to examine the efficacy of manualised CRT-O, which is intended to improve executive function, enhance reflective practice and help weight loss maintenance.

Methods/design: A randomised controlled trial (registered with the Australian New Zealand Clinical Trials Registry) will be conducted. First, 90 obese adults (body mass index >30 kg/m2) in the community will receive three weekly sessions of a group Behaviour Weight Loss Treatment (BWLT), and then will be randomised either to receive CRT-O or to enter a no-treatment control group. CRT-O training will comprise twice-weekly sessions of 45 minutes over a 4 to 6 week period, for a total of eight sessions. Measurement points will be at baseline, post CRT-O (or 4 to 6 weeks after BWLT for the no-treatment control), 3 months post treatment and 1 year post treatment. The primary outcome will be executive function and secondary outcome measures will include participants' body mass index, hip to waist ratio, eating behaviours and quality of life.

Discussion: This is the first study of its kind to examine the efficacy of Cognitive Remediation Therapy for obese adults through a randomised controlled trial.

Trial registration: Australian New Zealand Clinical Trials Registry number: 12613000537752. Date of registration: 14 May 2013.

Mentions: Recruitment was via advertisements placed on social media sites, university and community centre notice boards and via media interviews with journalists from metropolitan and community newspapers. The initial screen was by phone to establish potential eligibility. This was followed by a face-to-face psychological and neuropsychological assessment. All 90 participants then receive group-based BWLT that will run once a week for 3 weeks, each session lasting 90 minutes. At the completion of the third and final session, participants are randomly allocated to CRT-O or no treatment. Randomisation and allocation concealment are conducted using an external computer-based program [31]. The RCT is registered with the Australian New Zealand Registry of Clinical Trials (trial id ACTRN12613000537752) (FigureĀ 1).Figure 1
