Implementation of the extension phase of the Project P.A.T.H.S. in Hong Kong: observations based on the Co-Walker Scheme.

The implementation quality of the Tier 1 Program (Secondary 1 Program) of the Project P.A.T.H.S. in the second year of the Extension Phase was examined in this study, with classroom observations of 218 units in 172 schools. Results demonstrated that the overall level of program adherence was generally high with an average of over 90%. Different aspects regarding program delivery were significantly correlated, suggesting that different aspects of program implementation were intimately related. Regarding predictors of global implementation quality, analyses indicated that overall implementation quality was significantly predicted by interactive delivery method, achievement of objectives, time management, and lesson preparation; success of implementation was predicted by student participation and involvement, interactive delivery method, achievement of objectives, and time management. The present study replicated the findings in previous studies.
