A model of use willingness for wearable devices in middle-aged and elderly people based on theory of planned behavior
Objective To explore the use willingness for wearable devices in middle-aged and elderly people based on theory of planned behavior,and to provide evidence for future intervention measures.Methods Based on basic frame-work of theory of planned behavior,a self-designed questionnaire was developed and a multi-stage stratified whole-group sampling method was used to select middle-aged and elderly people in Nanjing to conduct a questionnaire survey.Structural e-quation modeling method was applied to carry out data analysis.Results A total of 288 valid questionnaires were re-turned.The model constructed based on theory of planned behavior explained 56.3％of the variance in middle-aged and ol-der adults'willingness to use wearable devices.Attitudes(path coefficient=0.274,P＜0.001),subjective norms(path coefficient=0.304,P＜0.001)and perceived behavioral control(path coefficient=0.361,P＜0.001)showed direct positive effects on use willingness for wearable devices.Subjective norms(path coefficient=0.1 14,P＜0.001)and per-ceived behavioral control(path coefficient=0.109,P＜0.001)showed indirect positive effect on use willingness through behavioral attitudes.Conclusion The willingness to use wearable devices among middle-aged and elderly people in Nanjing is high.The theory of planned behavior explained the use willingness for wearable devices among middle-aged and elderly people,and the frame is acceptable for implementing an intervention program.
