Abstract: | This paper describes the development of a knowledge measure for the evaluation of a proactive training program for suicide postvention and analyses of its psychometric properties. The 25-item true–false knowledge test was administered before and after each of 12 training sessions; a total of 205 school personnel participated in the training and evaluation. Participants showed significant improvement in overall test scores and on several individual items following the training. Analyses suggested that the measure has construct validity, and that it taps a single underlying dimension. Strengths and weaknesses of the measure, and measurement issues in program evaluation are discussed. |
