Questionnaires are frequently used in social science studies.However,traditional questionnaires failed to effectively contribute to the targeted goals of question phases or overall evaluation.This study researched an investigation method termed the correlation questionnaire.The questionnaire was divided into three levels:the phase level,the question level and the performance level.The analysis results showed that the correlation questionnaire provides an overall performance effectiveness evaluation and comparative assessment for an individual program.In addition,when weighting values were added to the phase level,in accordance with the effective degree to questionnaire goal,they can effectively reflect the performance of the questionnaire goal.
