Participants: 42 students, in the contemplation stage at baseline, were randomly assigned to an experimental group (16 women, 2 men; M age = 19.1 ± 1.15) and a control group (18 women, 2 men; M age = 20.1 ± 5.7). Methods: Physical activity was measured at different moments by accelerometry. Other cognitive variables were measured by self-reported scales. Results: We did not find any significant increases in students’ physical activity in favor of the intervention group. Intragroup analyses indicate that the intervention has an effect on physical activity (moderate-to-vigorous physical activity), basic psychological needs, and intrinsic and extrinsic motivation. Conclusions: Results partially demonstrate that applying social cognitive theories seems to be effective in improving physical activity and cognitive variables in university students in the contemplation stage info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.849 2019 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 32 / 169 = 0.189 2019 Q1 T1 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 58 / 193 = 0.301 2019 Q2 T1 ENVIRONMENTAL SCIENCES 105 / 264 = 0.398 2019 Q2 T2 0.739 2019 Health, Toxicology and Mutagenesis 2019 Q2 Public Health, Environmental and Occupational Health 2019 Q2 Pollution 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Zaragoza, Javier Universidad de Zaragoza (orcid)0000-0002-9761-1953 Julian, Jose Antonio Universidad de Zaragoza (orcid)0000-0002-7076-6621 Rodriguez-Ontiveros, Victor Hugo (orcid)0000-0002-6963-0727 Medrano, Carlos Tomas Universidad de Zaragoza (orcid)0000-0001-7671-7540 Plaza, Inmaculada Universidad de Zaragoza (orcid)0000-0001-7550-6688 Abarca-Sos, Alberto Universidad de Zaragoza (orcid)0000-0002-9208-4824 3001 187 Universidad de Zaragoza Dpto.
