“…Significant positive correlations between the level of physical activity and social support scores were identified, reinforcing findings from other studies 28,29 . The social support provided by parents and friends are consistently associated with higher levels of adolescents physical activity practice [12][13][14] .…”

“…These measures tend to overestimate the level of physical activity of adolescents 27 . However, the correlation coefficients were in the expected direction and magnitude, resembling those of other studies 28,29 . This study also has its strengths.…”

“…The construct validity of the ASAFA scale was observed by the presence of a significant association between the adolescents` level of physical activity and the score of social support for physical activity practice, as reported in previous studies 28,29 . Significant positive correlations between the level of physical activity and social support scores were identified, reinforcing findings from other studies 28,29 .…”

“…It is widely documented that social support from parents and from friends are associated in a particular way with physical activity, indicating that this construct has two distinct dimensions and specific implications for physical activity 7,13,14 . As noted in this study, others also have identified the presence of two factors on social support for physical activity scales, containing items targeted to parents and to friends 10,[28][29][30] . Dishman et al 10 , when performing the confirmatory factor analysis of a scale of social support for physical activity (with some items similar to this study), also verified the presence of the same factors.…”

AbstrAct:Objective: To analyze the reliability and validity of a scale used to measure social support for physical activity in adolescents -ASAFA Scale. Methods: This study included 2,755 adolescents (57.6% girls, 16.5 ± 1.2 years of age), from Joao Pessoa, Paraiba, Brazil. Initially, the scale was consisted of 12 items (6 for social support from parents and 6 from friends). The reliability of the scale was estimated by Cronbach's alpha coefficient (α), by the Composite Reliability (CR), and by the model with two factors and factorial invariance by Confirmatory Factor Analysis (CFA) adequacy. Results: The CFA results confirmed that the social support scale contained two factors (factor 1: social support from parents; factor 2: social support from friends) with five items each (one item was excluded from each scale), all with high factor loadings (> 0.65) and acceptable adjustment indexes (RMR = 0.050; RMSEA = 0.063; 90%CI: 0.060 -0.067); AGFI = 0.903; GFI = 0.940; CFI = 0.934, NNFI = 0.932). The internal consistency was satisfactory (parents: α ≥ 0.77 and CR³ ≥ 0.83; friends: α ≥ 0.87 and CR ≥ 0.91). The scale`s factorial invariance was confirmed (p > 0.05; ∆χ 2 and ∆CFI ≤ 0.01) across all subgroups analyzed (gender, age, economic class). The construct validity was evidenced by the significant association (p < 0.05) between the adolescents physical activity level and the social support score of parents (rho = 0.29) and friends (rho = 0.39). Conclusions: The scale showed reliability, factorial invariance and satisfactory validity, so it can be used in studies with adolescents.

“…The socio-ecological theory emphasizes that PA may be influenced by interpersonal (e.g., self-efficacy), interpersonal (e.g., social support) and environmental (e.g., neighborhood environment) factors 2 . Although this theory does not define or establish which constructs should be measured, some instruments of the factors associated with PA 3,[5][6][7] have been based on the socio-ecological theory.…”

-This study aimed to examine the validity and reliability of scales of intrapersonal, interpersonal, and environmental factors associated with physical activity (PA) in secondary students. Two cross-sectional studies were conducted with students in 7th to 9th grades form secondary schools in order to test the validity, internal consistency (n = 1,178, 51.4% were boys), and test-retest reproducibility (n = 194, 56.2% were boys) of the instrument. Factors associated with PA (attitude, self-efficacy, social support of friends, parents and the school's teachers, as well as the perceived neighborhood environment and perceived school environment) were measured. The confirmatory factor analysis and Spearman correlation between the scales and the weekly time spent in moderateto-vigorous PA (measured by questionnaire) were applied to test the construct validity. For reliability, the Cronbach's α (internal consistency), composite reliability (CR) and intraclass correlation coefficient (ICC for test-retest reproducibility) were applied. The confirmatory factorial analysis showed five one-dimensional and two two-dimensional (self-efficacy and perceived environment) scales, with factor loadings ranging from 0.46 to 0.85. Significant and positive correlations between almost all scale scores and moderateto-vigorous PA (p<0.05) were found. The Cronbach's α and CR were greater than 0.70 in almost all scales (except perceived school environment, α and CR of 0.61) and the ICC ranged from 0.62 (parental social support) to 0.70 (self-efficacy). In conclusion, the scales showed acceptable validity and reliability and can be used for measuring of PA correlates in elementary students.
