We propose stress management behavior, exercise, and scheduled sleep to represent the general intention and actual practices aimed to relieve stress by the application of the transtheoretical model (TTM). Randomly selected Chinese adults aged 18 - 64 were tested through an internet survey. The stage distributions for the three health behaviors were different across the Chinese adults. Stress was significantly higher in action and maintenance stages than in precontemplation and contemplation stages across three health behaviors. Our findings have provided preliminary findings on the applicability of TTM on the three health behaviors in Chinese adults with evidence of concurrent criterion validity.
