Having a good quality of life has always been desirable for humans, and the concept of a good life and the ways of achieving it have become important over the years. Personal wellbeing is the mental component of quality of life. Thus, the current study was conducted to assess the reliability and validity of the ''Personal Well-Being Index- Cognitive Disability'' on mentally retarded students.
200 mentally retarded students in north districts of Tehran (districts 1, 2 and 3) were selected by systematic random sampling. The collected data using Personal Well-Being Index- Cognitive Disability was analyzed by Cronbach's alpha coefficient for internal consistency and linear multivariate regression for construct validity.
Results confirmed the reliability and validity for the Personal Well-Being Index- Cognitive Disability in mentally retarded students of exceptional schools. Studying the internal consistency of seven items showed that all the items were correlated with the total score and their scores averages were similar to each other. This indicates that the test's questions have reliability with regard to evaluation of a common feature and results showed Personal Well-Being Index- Cognitive Disability had the most extensive coverage of construct validity.
Personal Well-Being Index- Cognitive Disability scale could be applied to measure personal wellbeing in mentally retarded students.
拥有良好的生活质量一直是人类所期望的，多年来，美好生活的概念及其实现方式变得至关重要。个人幸福感是生活质量的心理组成部分。因此，本研究旨在评估“个人幸福感指数 - 认知障碍”在智障学生中的信度和效度。
通过系统随机抽样，选取了德黑兰北部地区（第1、2和3区）的200名智障学生。使用“个人幸福感指数 - 认知障碍”收集的数据，通过Cronbach's α系数分析内部一致性，通过线性多元回归分析结构效度。
结果证实了“个人幸福感指数 - 认知障碍”在特殊学校智障学生中的信度和效度。对七个项目的内部一致性研究表明，所有项目均与总分相关，且其得分平均值彼此相似。这表明该测试的问题在评估共同特征方面具有可靠性，结果表明“个人幸福感指数 - 认知障碍”具有最广泛的结构效度覆盖范围。
“个人幸福感指数 - 认知障碍”量表可用于测量智障学生的个人幸福感。
