Sixty-five from a total of 160 medical students were administered the California Psychological Inventory (CPI) to identify which of all 18 scales can be used as a predictor for academic performance. The entrance examination scores of six subjects were also combined with the CPI variables for the purpose of the study. Students' performances were determined by Grade Point Average (GPA) collected between 1993-1997 (year 1 to year 5). Data was analyzed by descriptive and stepwise method of multiple linear regression analysis. The results showed that mathematics, biology and English language were positively correlated with all year GPAs-r2 value was 10-18 per cent. Scales of "dominance", "flexibility" and "socialization" were positively correlated to the GPA, while "sociability" and "sense of well-being" were negatively correlated. R2 value was increased to 16-59 per cent as prediction of GPA when the CPI variables were combined with scores of entrance examination. A comparison of this finding with other studies was conducted.
160名医学专业学生中的65名接受了加利福尼亚心理调查表（CPI）测试，以确定18个量表中哪些可作为学业成绩的预测指标。为了该研究，还将六门科目的入学考试成绩与CPI变量相结合。学生的学业表现由1993年至1997年（第1年至第5年）收集的平均绩点（GPA）来确定。数据采用描述性和逐步多元线性回归分析方法进行分析。结果显示，数学、生物和英语与各年的GPA呈正相关——r2值为10%至18%。“支配性”、“灵活性”和“社会化”量表与GPA呈正相关，而“社交性”和“幸福感”量表与GPA呈负相关。当CPI变量与入学考试成绩相结合时，作为GPA预测指标的r2值提高到了16%至59%。还将这一研究结果与其他研究进行了比较。
