Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed. Following consent participants received a sealed numbered envelope containing either a treatment CD or dummy CD.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation was used using a computerised sequence generation
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Analysis will be performed on an intention-to-treat basis. Multivariable analysis will be used to account for correlated readings within each individual over time and examine the association between each outcome and study arm. Baseline values will be treated as covariates rather than a response variable in the model. Thus, we will test whether outcome measures at 8 and 16 weeks differ between conditions controlling for baseline scores and other covariates that are identified as influencing the outcome.

Summary
Brief summary
Mindfulness-based intervention programs are a promising intervention in the treatment of psychological distress in a range of clinical populations including pain disorders, cancer and other medical problems. There is, however a paucity of studies that have examined mindfulness in people with diabetes. The few studies that have been undertaken have shown the intervention to result in improvements in emotional well-being (anxiety and depression), improved self-care behaviours and decreased HbA1c values.

This study will assess the effects of a mindfulness-based intervention undertaken and self-directed in people with diabetes at home over an eight-week period.

This study will seek to determine whether a mindfulness-intervention undertaken in the patients’ home can:
Reduce anxiety and depression
Reduce perceived diabetes –specific stress
Improve diabetes self-care and management
Improve glycemic control (HbA1c)
Increase mindfulness strategies (acceptance and action) in relation to diabetes
