BACKGROUND
The purpose of the present study was to assess the validity and reliability of Form A of Multidimensional Health Locus of Control scales in Iran. Health locus of control is one of the most widely measured parameters of health belief for the planning of health education programs.
METHODS
496 university students participated in this study. The reliability coefficients were calculated in three different methods: test-retest, parallel forms and Cronbach alpha. In order to survey validity of the scale we used three methods including content validity, concurrent validity and construct validity.
RESULTS
We established the content validity of the Persian translation by translating (and then back-translating) each item from the English version into the Persian version. The concurrent validity of the questionnaire, as measured by Levenson's IPC scale was .57 (P < .001), .49 (P < .01) and .53 (P < .001) for IPC, respectively. Exploratory principal components analysis supported a three-factor structure that items loading adequately on each factor. Moreover, the approximate orthogonal of the dimensions were obtained through correlation analyses. In addition, the reliability results were acceptable, too.
CONCLUSION
The results showed that the reliability and validity of Persian Form A of MHLC was acceptable and respectable and is suggested as an applicable criterion for similar studies in Iran.
背景
本研究旨在评估多维健康控制点量表A版在伊朗的有效性和可靠性。健康控制点是健康教育项目规划中测量最广泛的健康信念参数之一。
方法
496名大学生参与了本研究。通过三种不同方法计算信度系数：重测法、平行形式法和克朗巴赫α系数法。为了调查量表的效度，我们使用了三种方法，包括内容效度、同时效度和结构效度。
结果
我们通过将英文版的每个项目翻译成波斯文版本（然后再回译）来确定波斯文翻译的内容效度。问卷的同时效度，通过莱文森的内控性、有势力的他人及机遇量表（IPC）测量，IPC的分别为0.57（P < .001）、0.49（P < .01）和0.53（P < .001）。探索性主成分分析支持了一个三因素结构，各项目在每个因素上的载荷都足够。此外，通过相关分析获得了维度的近似正交性。此外，信度结果也可以接受。
结论
结果表明，MHLC波斯文A版的信度和效度是可以接受和值得认可的，并建议作为伊朗类似研究的适用标准。
