Universidad de Zaragoza (orcid)0000-0003-4795-5798 Expectancy-value model related to physical activity behaviors in chilean and spanish adolescents 2020 Access copy available to the general public Unrestricted The purpose of the study is to comparatively test the expectancy-value model in Chilean and Spanish samples. The model proposes: a social world (composed of social support, physical activity teasing, and weight teasing), expectancy (composed of perceived competence and appearance), task values (composed of enjoyment and stress) to predict physical activity and intention to be physically active. Participants were 497 (Chilean) and 1365 (Spanish) adolescents. Structural equation models and multi-group modelling were used. All the models presented adequate fit to the data. The results show that physical activity teasing is a contextual and essential variable; perceived competence and enjoyment influenced physical activity and intentions to be physically active; some differences appeared in the prediction of physical activity and intentions to be physically active when the multi-group model was run. Culturally tailored interventions are key to improving physical activity (PA) behaviors. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.39 2020 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 41 / 176 = 0.233 2020 Q1 T1 ENVIRONMENTAL SCIENCES 118 / 273 = 0.432 2020 Q2 T2 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 68 / 203 = 0.335 2020 Q2 T2 0.747 2020 Health, Toxicology and Mutagenesis 2020 Q2 Public Health, Environmental and Occupational Health 2020 Q2 Pollution 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Abarca-Sos, A.
