title: Robustness of a model of exercise.
abstract: A recent longitudinal study of exercise behavior was published in this journal. A structural equation model derived from the theory of reasoned action was evaluated and found to fit the data well. This paper presents further analysis of the data to determine the robustness of the results to modifications of the original model.
