Psychological Predictors of Intention to Use Fitness Apps: The Role of Subjective Knowledge and Innovativeness

ABSTRACT

Health and fitness apps have grown exponentially during covid-19 lockdowns. Using a sample of 331 European fitness apps users, this study investigated the psychological drivers of users' intention on fitness apps. This study draws upon the Technology Acceptance Model (TAM) and innovation diffusion theory. Its findings reveal that subjective knowledge and personal innovativeness predict perceived Usefulness, health consciousness, and ease of use. The strongest predictor of intention to use an app is perceived Usefulness, which mediates the influence of subjective knowledge and innovativeness on intention to use. Health consciousness predicts ease of use;however, the latter does not predict behavioural intention. This is one of the first studies on European users of fitness apps and investigating the psychological antecedents of TAM, i.e., innovativeness, subjective knowledge, and consciousness.
