津医精神运动成套测验(JPB)的探索性因素分析

Exploratory factor analysis on Jinyi Psychomotor Battery of test (JPB)

目的 :探索津医精神运动成套测验的理论结构效度。方法 :采取极大似然方法 ,对JPB城市和农村标准化常模样本进行因素分析 ,以累积贡献率不小于65 %为标准抽取因素。结果 :城市和农村JPB各分测验相关系数在-0.290至0.364和 -0.299至0.397之间 ,因素分析显示JPB城市和农村常模由结构非常相似的4因素模型构成。结论 :证实JPB主要由“速度”、“准确”、腕指灵活性和短时记忆4因素构成。

Objective: To explore the theoretical structure of Jinyi Psychomotor Battery of test (JPB).Methods: Maximum likelihood method, one of the exploratory factor analyses, was used to analyze data from rural and urban standardization norm respectively. The criterion of extracting factor was established with more than 65% of cumulative contribution rate. Results: The correlation coefficients of each subtest of JPB were distributed from -0.290 to 0.364 in cities and from -0.299 to 0.397 in rural areas. The results of factor analysis reveal that the structure of rural and urban tests constitutes of similar four factors. Conclusion: JPB are composed of speed, accuracy, agility of wrist-finger and short-term memory.
