Abstract BackgroundUnderstanding 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. MethodsMeasurement 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.ResultsThe studied motivational constructs showed scalar invariance. Latent mean levels of perceived social support and barrier self-efficacy were lower in South Africa and Sweden. Structural models (for different PA outcomes) were not consistent across settings except for the association between perceived social support and identified regulation. Identified regulation was only associated with vigorous PA in Uganda and with moderate PA in South Africa. The association between social support and PA outcomes ranged from weak to not significant and the association between self-efficacy and PA was not significant. Self-reported PA was highest in Uganda and lowest in Sweden. Self-reported vigorous PA was significantly related to lower hemoglobin A1c levels, while moderate PA was not.ConclusionsFindings suggest that: 1) it is feasible to compare a motivational process model across diverse settings; 2) there is lower perceived social support and self-efficacy in the urban, migrant samples; 3) identified regulation is a more promising determinant of PA than self-efficacy or social support in these populations; 4) associations between motivational determinants and PA depend on the perceived type and/or intensity of PA; 5) perceived relatedness functions as a basic psychological need across diverse settings; and 6) people’s perception of the PA they perform depends on their perceived level of intensity of PA which would have major implications for health promotion.

Youth Activity

Background:If the Youth Physical Activity Promotion (YPAP) model adequately explains youth physical activity (PA) in 2 different cultures and with 2 different sets of instruments, it would suggest that the model has broad utility for youth activity promotion.Methods:Two samples from different countries were used: sample 1—USA, 159 students (n = 83 girls) mean age 11.52 ± 1.40 years; sample 2—Portugal, 203 students (n = 125 girls) mean age 14.99 ± 1.55 years. PA was assessed by accelerometry. The YPAP model was analyzed through structural equation modeling using AMOS (version 17.0).Results:In sample 1, social-support had a direct association on MVPA (β = .58, P < .001), enjoyment (β = .70, P < .05), and self-efficacy (β = –.66, P < .001). Enjoyment significantly predicted MVPA (β = .60, P < .001) and self-efficacy significantly predicted MVPA (β = .55, P < .001). In sample 2, social-support had a direct effect on MVPA (β = .33, P < .05), significantly predicted enjoyment (β = –.43, P < .001), and significantly predicted self-efficacy (β = .63, P < .001). Self-efficacy was a significant predictor of MVPA (β = .14, P < .001) but enjoyment was not.Conclusions:Differences were noted in the nature of the relationships and the relative importance. Self-efficacy and social support had significant effects on MVPA in both samples—despite differences in the way that they were measured and operationalized.

Social support (SS) from parents and peers are key reinforcing factors in the Youth Physical Activity Promotion (YPAP) model. This study aims to identify the relative contribution of parental and peer SS on youth participation in moderate to vigorous physical activity (MVPA). Participants included 203 high school students (n = 125 girls; mean age 14.99 ± 1.55 years). MVPA was assessed by accelerometry. SS influences were evaluated using a well-established scale. Structural equation modeling measured (AMOS, Version 19) the relative fit of the YPAP models using both parental and peer SS. Parental SS had significant associations with both predisposing factors, enjoyment (β = .62, p < .01), and self-efficacy (β= .32, p < .01), as well a direct effect on MVPA (β = .30, p < .01). Peer SS had direct effect on MVPA (β = .33, p < .05), also significantly influenced levels of enjoyment (β = .47, p < .01) and self-efficacy (β = .67, p < .01). In both models self-efficacy mediated the influence on MVPA. The direct effects for parents and peers were similar. This demonstrates that both parental and peer social support exert a strong influence on adolescent MVPA.

Objective:The purpose of this study was to examine, using structural equation modeling, the associations between nominated friend physical activity (PA), friend social support with individual PA-related psychological factors, and adolescent PA.Methods:Data were obtained from EAT 2010 (Eating and Activity Among Teens), a large cross-sectional study conducted in 20 middle and high schools. The sample consisted of 1951 adolescents (mean age: 14.25 ± 1.96, 54% female, 68% ethnic minorities). PA, parent and friend social support (perceived social support for PA from parents and friends), and psychological measures (PA enjoyment, PA self-efficacy, and PA barriers) were assessed by self-report questionnaires. The SEM analysis consisted of 1 observed variable: friend PA, and 2 latent constructs: psychological factors, perceived social support.Results:The model was a good fit, indicating that there were significant direct effects of both friend PA (P < .01) and psychological factors (P < .0001) on adolescent PA. In addition, psychological factors mediated the association between friend PA and adolescent PA.Conclusion:The results of this model suggest that psychological factors and friend PA are associated with adolescent PA, and that psychological factors may play an important role. Future studies should further examine the association of both friend PA and psychological variables with adolescent PA.

Abstract Background Few assessment tools exist for investigating perceived social support and self-efficacy behaviors in Arabic-speaking populations. Moreover, literature on the levels of social support and self-efficacy for adopting healthy eating and engaging in regular physical activity among Arabic-speaking young adults is currently lacking. This study aimed to adapt the Health Beliefs Survey Questionnaire (HBSQ) for Arabic-speaking populations and assess perceived social support and self-efficacy for adopting healthy eating and increased physical activity among university students. Methods In the first stage of the study, forward and backward translation and pretesting of the social support and self-efficacy scales of the HBSQ were conducted. The adapted questionnaire was administered to female university students (n = 258), and a subsample of 195 participants retook the questionnaire after 1 month. Construct validity was assessed with confirmatory factor analysis. The internal consistency of each subscale item was assessed by Cronbach’s alpha coefficient, and reproducibility was tested with intraclass correlation coefficients (ICCs) and Bland-Altman plots. In the second stage, the adapted questionnaire was used to assess the perceived social support and self-efficacy levels in a different sample of Arabic-speaking female university students (n = 283). Results Based on the results from confirmatory factor analysis, 6 items were selected for the social support scale and 19 items for the self-efficacy scale. The adapted questionnaire showed moderate to high internal reliability (Cronbach alpha coefficient = 0.681 to 0.900). The ICCs of the various subscales ranged from 0.666 to 0.997, indicating moderate to excellent reproducibility of the culturally adapted questionnaire. This was confirmed by Bland-Altman analysis. Participants in the second stage of the study reported significantly higher (P < 0.001) perceived support from family compared to friends in reducing sugar intake and increasing fiber consumption. Conclusions The results of the psychometric testing indicate the shortened Arabic HBSQ is a reliable tool for assessing perceived social support from family and close friends as well as for evaluating self-efficacy for choosing healthy foods and increasing physical activity among female university students.

Psychological Need Satisfaction

Using self-determination theory, we examined the mechanism of motivation in the context of physical activity (PA). We conducted structural equation modeling with 431 participants. The results showed general support for the motivational process model, in which a sequence is specified from autonomy support and causality orientations to psychological need satisfaction to self-determined behavioral regulation to PA behavior. These findings aid understanding of the underlying motivational mechanism of PA behavior, and highlight the positive roles of autonomy support and autonomy orientation in psychological need satisfaction, self-determined behavioral regulation, and PA participation.
