The relationship between exercise intention and behavior of Chinese college students: A moderated mediation model

Abstract

Inconsistency between intention and behavior is very common in daily life. This study explored the intention-behavior relationship in exercise, focusing on the mediating effect of action planning and the moderating effects of habit strength and gender. For the purpose of providing theoretical reference for the implementation of intervention strategies in the volitional phase, a total of 489 college students (M-age = 20.61, 57.46% female) from Hubei Province, China, were recruited to complete the questionnaire at two time points. The findings showed that exercise intention could positively predict exercise behavior via the mediating effect of action planning, with the mediating effect accounting for 48.52% of the total effect. The predictive effect of action planning × habit strength interaction on exercise behavior was statistically significant. As individuals’ levels of habitual strength increased, so did the relationship between action plans and exercise behavior. The action planning-exercise behavior relationship was stronger in males than in females. In summary, action planning is a very important predictor of the post-intentional phase and has many advantages. For individuals whose exercise has become habitualized, forming a plan is not counterproductive and can still promote more exercise rather than in a mutually compensating manner.

Exercise adherence and suicidal ideation of Chinese college students: a chain mediation model test

“…The higher the score, the higher the meaning of life of the subjects. Studies have shown that the scale has good reliability and validity among Chinese college students (Zhu et al, 2022). In this study, the Cronbach α coefficient of the scale was 0.945.…”

“…4 Research evidence has indicated that bedtime procrastination is related to many negative health conditions, such as sleep insufficiency, poor sleep quality, high levels of daytime fatigue and sleepiness. 5 , 6 Thus, given the links between bedtime procrastination and these adverse consequences, it is vital to examine the predictors of bedtime procrastination and possible mechanisms to inform a more holistic physical and mental health intervention and promotion approach for college students.…”

Relationship between sleep quality and subjective well-being: resilience as a mediator and belief in a just world as a moderator

“…During their university years, individuals often have more flexible schedules, but a lack of guidance and supervision in aspects of healthy living can lead to variable sleep patterns and irregular routines, negatively impacting sleep quality ( 8 , 41 ). The prevalence of staying up late and nocturnal activities among college students further affects their sleep quality ( 42 ). Lower sleep quality fails to alleviate negative emotions in college students, resulting in weaker subjective well-being.…”
