内控性、有势力他人及机遇量表用于中国军人心理控制能力调查的信度与效度评价

An evaluation of validity and reliability on the internality, powerful others and chance scales using for Chinese soldier

目的 探讨内控性、有势力他人及机遇（IPC）量表用于中国军人心理控制能力测量的可能性。方法采用横断面研究，使用IPC量表对新疆地区331名军人的心理控制能力进行问卷调查测定，分析其信度、效度。结果本次研究中，IPC量表的总分半信度为0．72，量表中的内控性、有势力他人及机遇3个分量表的分半信度分别为0．66，0．70，0．81；内控性、有势力他人及机遇3个分量表的同质性信度分别为：0．60，0．75，0．78，满足群组比较的要求。因子分析产生的3个共因子与理论结构基本一致，结构效度的累积方差贡献为60．12％。结论 为IPC量表适用于中国军人心理控制能力调查提供一定的科学证据。

Objective To study the possibility of measuring the controllability of psychological for Chinese soldier by the internality,powerful others and chance（IPC） scale. Method Using cross-sectional study, the locus of control in 331 Chinese soldiers was measured simultaneously by IPC. And the validity and reliability were analyzed. Results In the study, the split-half reliability of the IPC scale was 0.72. The split-half reliability of the internality,powerful others and chance scales were 0. 66,0. 70,0. 81, respectively. The Cronbach＇ s α coefficient of internal consistency reliability of the internality ,powerful others and chance scales were 0. 60,0. 75 ,0. 78 , respectively. That was satisfactory for group comparison. The correlations between an item and its hypothesized scale were identical for all scales. The three common factors from factorial analysis were in accordance with their theoretical structure, and the cumulative contribution rate was 60.12%. Conclusion The IPC scale has achieved equivalence well enough to warrant wide use in Chinese soldiers.
