FERREIRA, Gabriela  and  PEREIRA, M. Graça. Validation of the questionnaire of planned behavior on diabetes: physical activity. Psic., Saúde & Doenças [online]. 2014, vol.15, n.2, pp.409-426. ISSN 1645-0086.

The aim of this study was to validate the “Questionnaire of Planned Behavior on Diabetes - Physical Activity”, in a sample of type 2 diabetes patients. This questionnaire assesses variables of physical activity based on Planned Behavior Theory: intentions, attitudes, subjective norms, perceived behavioral control, action planning and coping planning. The instruments administered were: Revised Summary of Diabetes Self-care Activities (Investigation version of Pereira, Costa, & Castro, 2008) and Trust in Physician Scale (Portuguese version of Pereira, Pedras, & Machado, 2013). In this study participated 120 patients (39,2% women and 60,8% men) diagnosed with T2DM, whose average age was 59,7. Factor analysis found five factors, that explained 76,15% of the variance. Cronbach alphas were satisfactory and the instrument showed appropriate construct and discriminant validity.
