Scientific title	Written emotional disclosure for adults with type 2 diabetes: a single centre parallel group randomised controlled trial
Study acronym	NA.
Study objectives	Milder symptoms of depression in chronic physical conditions such as type 2 diabetes are an important and inadequately addressed problem which has significant negative consequences for the individual's experience, and the course, of the condition. This study is a trial investigating whether an intervention that has been found to improve physical and mental health for individuals with chronic conditions, Written Emotional Disclosure (WED), is similarly effective for adults with type 2 diabetes, specifically UK primary and secondary care patients. The main hypothesis is that participants who receive WED will report lower levels of depressive symptoms, and also improvements in diabetes specific emotional distress, health related quality of life, health care use, self-management behaviours, and glycaemic control (i.e. HbA1c), compared to a control group. Also planned is an assessment of quality assurance, and an investigation of pre-specified mediators and moderators of effects and cost-effectiveness. This is in order to improve understanding of how WED affects health, and identify for whom WED is most effective and whether it is cost-effective.
Ethics approval(s)	Warwickshire NHS Research Ethics Committee approved on the 10th December 2008 (ref: 08/H1211/165). A substantial amendment was approved on the 6th July 2009.
Health condition(s) or problem(s) studied	Type 2 diabetes
Intervention	Intervention: Written Emotional Disclosure. This involves writing about personal thoughts and feelings about a stressful event. Control: A neutral writing condition in which people describe how they use their time. Both groups write for 20 minutes per day for 3 days over the course of one week.
Intervention type	Other
Primary outcome measure(s)	Symptoms of depression, measured by the CES-D at baseline and then 3 and 6 months post-intervention
Key secondary outcome measure(s)	Measured at baseline and 3 and 6 months post-intervention: 1. Diabetes specific emotional distress measured with the Problem Areas in Diabetes (PAID) Scale 2. Health care use measured with the Stanford Patient Education Research Centre Diabetes Health Care Utilisation Questionnaire 3. Diabetes self care behaviours measured with the Summary of Diabetes Self-care Activities Questionnaire (SDCAQ) 4. Glycaemic control (HbA1c) obtained from routine medical records 5. Health related quality of life measured with the EuroQoL
