The aim of this study was to report the development and the analysis of content validity and reliability of the Psychosocial Determinants of Physical Activity among Coronary Heart Disease Patients Questionnaire, based on an extension of the Theory of Planned Behavior. In the content validity step, three experts evaluated the instrument which was, afterwards, pre-tested with five subjects in order to obtain a conceptually appropriate and easily understood instrument. Fifty-one patients participated in the evaluation of internal consistency of the reviewed instrument. Cronbach's alpha coefficients above 0.75 were observed for the constructs: Intention, Attitude, Subjective Norm, Self-efficacy and Habit. The new instrument demonstrated acceptable evidence of content validity and reliability.
