Achieving the recommended amount of physical activity (PA) is linked to improved cognitive function, overall physical health, and protection against non-communicable diseases. However, most people surveyed in the United States do not meet the recommendations for PA; especially adolescents between the ages of 17-19. Evidence suggests that interventions for increasing PA must be considered acceptable before the individual will use them. This study explored the relationships between the attributes of acceptability of mHealth apps and adoption intention of mHealth apps in a sample of adolescents (n = 287). Participants completed a survey with 24 total items: 19 from the Acceptability of Health Apps for Adolescents (AHAA) survey and five additional items assessing response efficacy and adoption intention. Bivariate correlations were completed between each subscale of the AHAA, response efficacy, and adoption intention followed by multiple regression. Correlation coefficients indicated that there were statistically significant relationships between self-efficacy (β = .184, t(264) = 3.41, p < .05), response-efficacy (β = .209, t(264) = 3.51, p < .05), attitude (β = .392, t(264) = 6.43, p < .05), and adoption intention. The adolescents who demonstrated higher reports of self-efficacy, response-efficacy, and attitude reported an increased likelihood of app adoption for PA, with attitude most strongly predicting adoption intention. Results of this study may be beneficial for PA intervention efforts and mHealth app development for the adolescent population.
