Adherence and Compliance
Hypothesis 2 proposed that the blended training participants would be more adherent and compliant than the web-based training participants. Regarding the difference in dropout between the training formats, the web-based training participants were not more likely to drop out (80/198, 40.4%) than the blended training participants (65/196, 33.2%) at T1 (odds ratio [OR] 1.37, 95% CI 0.91-2.06) and T3 (web-based: 108/198, 54.5%; blended: 90/196, 45.9%; OR 1.41, 95% CI 0.95-2.10). At T2, the web-based training participants were twice as likely to drop out (91/198, 46%) as the blended training participants (67/196, 34.2%; OR 1.64, 95% CI 1.09-2.46). Regarding the difference in compliance between the training formats, the blended training participants were 17 times more likely to be compliant (142/143, 99.3%) than the web-based training participants (98/110, 89.1%; OR17.39, 95% CI 2.23-135.87). Thus, hypothesis 2 was partially supported.
