Objectives: To utilize the theory of planned behavior (TPB) in explaining the prediction of physical activity intention and determine if present activity behavior attenuates theory construct relationships in a sample of low-income Mexican women. Methods:
Data were gathered on 201 subjects through a self-report survey instrument and analyzed through structural equation modeling. Results: Present activity behavior attenuated theory construct influence on intention, and perceived behavioral control was the strongest predictor
of intent to engage in physical activity. Conclusions: Interventions promoting voluntary physical activity for this population group should address factors perceived as barriers to participating in activity situations.
The American Journal of Health Behavior seeks to improve the quality of life through multidisciplinary health efforts in fostering a better understanding of the multidimensional nature of both individuals and social systems as they relate to health behaviors.
The Journal aims to provide a comprehensive understanding of the impact of personal attributes, personality characteristics, behavior patterns, social structure, and processes on health maintenance, health restoration, and health improvement; to disseminate knowledge of holistic, multidisciplinary approaches to designing and implementing effective health programs; and to showcase health behavior analysis skills that have been proven to affect health improvement and recovery.
