Table 3 summarizes the students’ scores for different constructs. There were significant
differences between those who were brushing twice a day or more and those who were
brushing less than twice a day on several measures including perceived objective severity (P
= 0.001), perceived psychological barriers (P < 0.0001), and perceived self-efficacy (P <
0.0001). However, the other constructs did not show any significant results.
