(2021).Motivational determinants of physical activity in disadvantaged populations with (pre)diabetes: A cross-cultural comparison. Research square, 1–16.2693-501510.21203/rs.3.rs-613852/v1http://hdl.handle.net/10566/6556Understanding motivational determinants of physical activity (PA) is essential to guide the implementation of PA at individual and population level. Knowledge about the cross-cultural generalizability of these determinants is lacking and they have mostly been studied as separate factors. This study compares a motivational process model across samples from diverse populations with, or at risk of diabetes.Measurement invariance of barrier identified regulation, barrier self-efficacy and social support was assessed in a rural Ugandan sample (n=712) and disadvantaged samples with high proportions of immigrants in urban South Africa (n=566) and Sweden (n=147). These motivational determinants were then compared through multigroup structural equation modeling.enPhysical activitySelf-efficacySocial supportSouth AfricaType 2 diabetesMeasurement invarianceArticle
