title: Are exercise social-cognitive factors and behaviours different for adults with diabetes? A randomized community sample.
abstract: Exercise plays a key role in the prevention and delay of the onset of Type 2 diabetes and in the management of this disorder. To determine if there are differences in key social-cognitive determinants of exercise and self-reported physical activity levels between adults with diabetes and those without the condition, a random selected sample of adults was surveyed. A telephone interview assessed physical activity behaviour and key social-cognitive constructs from major health behaviour change theories/models. The mean energy expenditure was not significantly different between the diabetes (n = 46) and the non-diabetes (n = 1556) groups. The diabetes group reported significantly lower scores for self-efficacy and perceived behavioural control, but higher for fear of, and vulnerability to, general health and cardiovascular disease threat. The data suggest that it may not be necessary to promote health threat messages, as threat is already high for this diabetes population and studies have shown that excess threat does not promote recommended exercise and health behaviours. Instead, the low levels of self-efficacy and perceived behavioural control among those with diabetes emphasize the importance of designing specific strategies (e.g., skills, incremental success) to increase their self-confidence in undertaking physical activity.
