Assessment of decisional balance for regular physical exercise: Adaptation and validation of the Decisional Balance Scale for Exercise among a French sample

a b s t r a c t Objective. - The purpose of this study was to validate a French version of the Decisional Balance Scale for Exercise (BDAP) and to examine its psychometric properties as well as its relationship with the three other components of Transtheoritical Model (TTM). Participants and method. - Four hundred and six subjects (270 women), aged between 16 to 65 years old, fulfilled BDAP and other questionnaires measuring the three other components of TTM (Stages of Change of Exercise Behavior Scale, Exercise Processes of Change Questionnaire, Exercise Confidence Survey). Results. - Confirmatory factor analyses supported the two-factor model of BDAP (pros, ! = 0.85 and cons, ! = 0.73) assumed in the MTT. A good test-retest reliability was observed. BDAP was associated with the three other components of TTM. Conclusion. - The French version of the BDAP shows good structural and psychometric properties. BDAP may be used as a valid tool in French-speaking populations.
