Processes of change, pros, cons, and self-efficacy as variables associated with stage transitions for effective stress management over a month: a longitudinal study.

backgroundThe transtheoretical model of intentional health behavior change categorizes people into experiencing five stages in understanding the process of initiating and maintaining effective stress management (i.e., engagement in any form of healthy activity that is practiced for at least 20 min per day). The first purpose of this study was to observe whether any cases would disclose stage misclassification over one month. The second was to examine whether different model's variables are associated with the stage transitions for effective stress management at different stages.

methodsData from 946 Chinese students and workers were subjected to analyses. This study is a part of a larger, longitudinal web-based study in which three surveys were conducted in March, April, and September 2014. This study analyzes the data of demographic variables, perceived stress, stages of change, processes of change, pros, cons, and self-efficacy at the point of the first survey and stages of change at the point of the second survey.

resultsOf 144 participants who progressed from the pre-Action stages to the post-Action stages, 44 then progressed to Maintenance (practicing effective stress management for six months or longer). These patterns could not technically occur, and thus, these participants were excluded from the following analyses. Data from the remaining 902 participants were subject to a series of logistic regression analyses. Generally, the model's variables failed to predict the stage transitions. Exceptions were found that higher experiential processes (the cognitive activities required to progress through stages) and lower self-efficacy (the confidence that one can engage in effective stress management despite barriers to it) predicted the forward and backward stage transitions from Precontemplation (with no intention to initiate effective stress management in the next six months) and Action/Maintenance (practicing effective stress management).

conclusionsEvidence of stage misclassification indicated the limitations of the model's stage classification. Experiential processes and self-efficacy as predictors at different stages were in line with the model's assumption that different variables are assumed to be predictors of stage transitions at different stages, partially supporting the utility of the stage classification.
