Abstract:
Measures of correlates of youth smoking should be invariant. We examined the measurement invariance of smoking-related self-efficacy, beliefs, and intention across gender, race (White vs. Black), ethnicity (non-Hispanic vs. Hispanic), and grade level (9th/10th vs. 11th/12th grade) for 2767 high school current smokers. Strong factorial invariance was found in the factors across gender (NNFI:0.959; CFI:0.959; RMSEA:0.085), grade (NNFI:0.962; CFI:0.962; RMSEA: 0.079), race (NNFI: 0.967; CFI: 0.967; RMSEA: 0.074), and ethnicity (NNFI: 0.965; CFI: 0.965; RMSEA: 0.078). Smoking-related self-efficacy, beliefs, and intention measures may be confidently used to understand attitudinal differences across gender, race, ethnicity, and grade level for youth smokers.
