Abstract: In order to establish some scientific bases for setting down the efficient measure for rebuilding and correcting this study tried to explore the categorisedmodel of the drugpusher's personality. 378 male drugpusher prisoners were tested using CPI and then using SPSS package to explore the drugpusher's categoryby cluster analysis. Results showed that 387 cases of drugpushers were divided into three groups by hierarchical cluster analysis, t scores of 19 CPI sub scale were remarkably different among the three groups. The typical personality characteristic of the first category was lack of self confidence, disliking competion, self suspicion, passiveness, dependence, sensitiveness, and trending to explain things from the individual eye. The second category was cleverer, responding quickly, independent, responsible and good self control. They had betterpsychological diathesis but could not consciously admit their guilty behavior or admit their mistake and often had conflictive mind with the manager.The third category was better socially, self confident, fawning and worldly wise. They could manage a good relationship with others and selected an appropriate behavior to act or to disguise. The three Categorieswere Coward immaturity, Independence immaturity and Control immaturity and these three categoriesmade up an effective categorised model which could established a stable scientific base for rebuilding and correcting the drugpusher's psychological state.
