First, the word association method was used to collect data, where 370 college students freely associated words with “conscience” as the target word. The top 60 high-frequency words were selected as the units of analysis. Subsequently, 60 college students categorized these items, resulting in five high-order clusters of conscience. Another 600 college students were invited to evaluate the item questionnaire composed of these 60 conscience characteristic words. The results of exploratory factor analysis, hierarchical cluster analysis, and confirmatory factor analysis indicated that the implicit structure of conscience among college students comprises five factors: loving, wisdom, progressiveness, righteous deeds, and responsibility. The five-factor model of the implicit structure of conscience among college students reflects typical Chinese cultural characteristics, and the construction of this model will contribute to advancing the implementation of conscience and moral education.展开更多
