Examining the psychological pathways to behavior change in a group-based lifestyle program to prevent type 2 diabetes.

Objective: To examine the psychological process of lifestyle change among adults at risk for type 2 diabetes.

Research Design And Methods: A randomized control trial in which 307 volunteers (intervention, n = 208; wait control, n = 99) diagnosed with prediabetes completed a six-session group-based intervention to promote healthier living. Participants' motivation to change, diet and exercise self-efficacy, mood, knowledge about diabetes, activity levels, healthy eating, waist circumference, and weight were assessed before and after the program.

Can the onset of type 2 diabetes be delayed by a group-based lifestyle intervention? A randomised control trial.

This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test.
