α, Cronbach’s coefficient alpha. ^aPsychosocial items were scored on a scale of 1–5. Higher scores reflected higher levels of self-efficacy and higher levels of perceived barriers. ^bReliability was calculated based on indicator loadings and error variances from the single-factor CFA model for the measure. *P < 0.05. **P < 0.01.
