Based on the power analysis
program (MacCallum, Browne, &
Sugawara, 1996), the framework for
the RMSEA was used to estimate
the power of the SEM in the current
study. With alpha at 0.05, a null hypothesis RMSEA
of 0.05, and an alternative hypothesis RMSEA of 0.1,
degrees of freedom ranged from 120–130, and range
of statistical power for a sample size of 206 was from
0.95–0.97. Therefore, the current sample size (N = 206)
was sufficient for this study.
