*2.7. Sample Size Justification*

Sample size estimation of independent-samples-test was conducted using G \* Power software packages, using a Cohen's small effect size of 0.2 at the power of 95% [34,35]. After factoring a 15% attrition rate (*n* = 163), the minimum sample required was 1247 participants. For the purpose of structural equation analyses, a minimum sample size of 300 was determined to be acceptable, as indicated by previous studies [36].
