This study examined psychometric properties of the Levenson's Locus of Control Scale among Iranian infertile patients. In all, 312 infertile patients completed the Levenson's Locus of Control Scale and Hospital Anxiety and Depression Scale. The confirmatory factor analysis indicated that the original three-factor model of Levenson's Locus of Control Scale was adequate ( χ/ df = 2.139; goodness-of-fit index = 0.88; root mean square error of approximation = 0.061; and standardized root mean square residual = 0.076). The Cronbach's alpha of the subscales ranged from 0.56 to 0.67. The Levenson's Locus of Control Scale subscales significantly correlated with anxiety and depression, showing an acceptable convergent validity. In conclusion, the Levenson's Locus of Control Scale has adequate reliability and validity and can be used to measure locus of control orientation in Iranian infertile patients.
本研究旨在检验莱文森控制源量表在伊朗不孕患者中的心理测量特性。共有 312 名不孕患者完成了莱文森控制源量表和医院焦虑抑郁量表。验证性因子分析表明，莱文森控制源量表的原始三因素模型是充分的（χ/df=2.139；拟合优度指数=0.88；均方根误差近似值=0.061；标准化均方根残差=0.076）。分量表的克朗巴赫α系数范围在 0.56 到 0.67 之间。莱文森控制源量表分量表与焦虑和抑郁显著相关，表现出可接受的聚合效度。总之，莱文森控制源量表具有足够的信度和效度，可用于测量伊朗不孕患者的控制源取向。
