N2 - Repeated measures ANOVA and individual regression analysis are used in longitudinal data. Data from Chang (2006) study was illustrated the similarities and differences between them. The purpose of study was to test effects of a training program. Findings from RMANOVA concluded that treatment group had better knowledge (F=56, p< 0.001) and greater intention (belief: F=4.4, p=0.03) than control group. No conclusions could be drawn regarding direction, magnitude, and timing of change. Results from IRA indicated that there were significantly different patterns of change on knowledge (t=-4.8, p< 0.001), attitude (t=1.8, p=0.07), perceived behavior control (t=1.9, p=0.06), and intention (freq.: t=-2.3, p=0.02; beliefs: t=-2.7, p=0.01) between two groups. IRA and use of both methods as complementary are suggested.
