Cognitive predictors of physical activity behaviors among rural patients with type 2 diabetes: applicability of the Extended Theory of Reasoned Action (ETRA).

This study aims to examine the cognitive-behavioral determinants of physical activity behaviors (PABs) of patients diagnosed with type 2 diabetes. In this cross-sectional study, census sampling was employed to enroll 120 rural patients with type 2 diabetes in the Chalderan County in 2015. To collect data, a valid and reliable instrument, based on the Extended Theory of Reasoned Action (ETRA) constructs, was used.
