dc.description.abstractModerate to vigorous physical activity (MVPA) is important for the prevention of chronic illness throughout the lifespan. Nevertheless, only 27% of high school students in the United States (U.S.) engage in adequate daily MVPA. The purpose of this study was to test the theory of planned behavior (TPB) to predict MVPA in a predominantly Hispanic convenience sample of high school aged adolescents from a lower socioeconomic status community in northern New Mexico. A secondary purpose was to test mindfulness as a moderator of the relationship between intention and MVPA. The study had a prospective design with two waves of data collection conducted two weeks apart using self-report questionnaires during normal school hours (N = 232, M age = 15.23 years, SD = 0.94 years). Confirmatory factor analysis was used to test the measurement model followed by a path analysis using structural equation modeling to test the TPB to predict MVPA. Simple slopes analysis was used to test mindfulness as a moderator of the relationship between intention and MVPA. The TPB model adequately predicted intention and MVPA, explaining 60% of the variance in intention and 43% of the variance in MVPA. Attitude (β = .49) and subjective norm (β = .44) predicted intention while intention (β = .58) and perceived behavioral control (PBC) (β = .13) predicted MVPA. However, PBC did not predict intention and mindfulness did not moderate the relationship between intention and MVPA. The results suggest that the needs of this community may differ from those in other parts of the U.S., and therefore, warrant further investigation. Specifically, the strong influence of subjective norms on intention suggests that community and family centered care may be important tools for health promotion in this population. Future research should investigate the potential influence of culture on the TPB constructs in this population. Although mindfulness did not show the predicted effects, it may still be a construct of interest for future research on MVPA. Only through understanding potential influences on MVPA, including the gap between intention and behavior, will nurses be able to effectively develop targeted interventions to promote MVPA in this population.
