A total of 1744 participants comprising 44 groups participated in a 3-day Secondary 1 Training Program of Project P.A.T.H.S. in Hong Kong. At the end of the training program, the participants were invited to respond to a subjective outcome evaluation. Results showed that the assessment tools are internally consistent. Descriptive statistics revealed that evaluations of the respondents are positive in terms of the training program content, interaction, trainers’ performance, self-performance, administrative arrangement, and overall satisfaction. Overall satisfaction was predicted by training content, trainers’ performance, self-performance, and interaction. Training content and trainers’ performance explain half of the total variance. The present findings reiterate other studies regarding the effectiveness of the training program of Project P.A.T.H.S. in promoting the participants’ knowledge, attitude, and skills in delivering the program.
