Abstract:
Objective:To validate the physical activity model for the elderly in nursing homes based on the self-determination theory (SDT) under the Chinese scenario and provide a theoretical basis for future interventions by clarifying the relationship between autonomy support, basic psychological needs, motivation and physical activity in the elderly in nursing homes.Methods:Totally 204 senior citizens from 6 nursing homes in Shenyang City were selected by convenient sampling from March 7 to 13, 2018. The self-made general information questionnaire, Perceived Autonomy Support (PAS) , Psychological Need Satisfaction in Exercise Scale (PNSE) , Revised Behavioral Regulation in Exercise Questionnaire (BREQ-2) and pedometers were used to collected their basic information, autonomy support, psychological satisfaction in exercise, motivation and physical activity. The statistical method of structural equation model was employed to validate the model.Results:The coefficient of 14 paths in the model was significant [χ 2=44.81, degree of freedom ( df) =31, χ 2/ df=1.45, comparative fit index ( CFI) =0.99, root-mean-square error of approximation ( RMSEA) =0.05, standardized root-mean-square residual ( SRMR) =0.03], showing the model simulation was sound. Autonomy support could predict the level of physical activity through the complete mediation of basic psychological needs and motivation. The positive effect of autonomy support on basic psychological needs was 0.96, and the predictive power of the three basic psychological needs for motivation was attribution (0.93) , autonomy (0.88) , and competence (0.81) from high to low. The positive effect of basic psychological needs on autonomous motivation was 0.82, and their negative effect on controlled motivation and amotivation was -0.94 and -0.65, respectively. The positive effect of autonomous motivation on physical activity was 0.64. The negative effect of controlled motivation on physical activity was -0.22, and the negative effect of amotivation on physical activity was -0.19. Conclusions:As a model for understanding the generation and development process of physical activity motivation, SDT is universal and applicable to the elderly population in the context of Chinese culture.
