Understanding Physical Activity Environmental Correlates: Increased Specificity for Ecological Models

In Brief Ecological models are now used to understand the complex array of factors that influence physical activity, resulting in a greater emphasis on environmental correlates. This selective review examines whether the predictive capacity of these models could be improved if behavior-specific measures of the environment were used to predict context-specific behaviors. To improve the predictive capacity of research examining environmental correlates of physical activity, behavior and context-specific constructs are required.
