Predictors of physical activity following gestational diabetes: Application of health action process approach

Abstract

The common fit indices revealed that health action process approach had an acceptable fit to the observations (root mean square error of approximation = 0.054, Tucker-Lewis index = 0.95, comparative fit index = 0.955). The model's constructs predicted 48% of intention variance and 35% of physical activity variance. Action self-efficacy and coping planning were the most important predictors of intention and behaviour, respectively.
