Choice theory, as a psychopathological model, postulated five basics, genetically and universally, needs. Accordingly, the rate of everybody happiness and quality of life is depended on the number of his needs fulfilling. Although some scales have been constructed to assess basic needs, they have proposed unity of needs for all human.
The present study was designed to construct a new scale, considering individualisation needs for each person; quality of life scale based on choice theory (QOLSCT).
Using cluster sampling, six hundred (49% female and 51% male) postgraduate students were selected. One hundred fifty participants also filled SF-36 and GHQ, and 80 participants refilled QOLSCT with four weeks' interval again.
Cronbach's alpha, split-half and test re-test (one month) reliability scores were 0.78, 0.75, and 0.92 successively. The correlation between items and total scores range from 0.36 to 0.72, all with P values ≥ 0.0001. Confirmatory factor analysis showed satisfactory values of goodness-of-fit indices, RMSEA, CFI, NFI and GFI were, 0.05, 0.99, 0.99 and 0.99 respectively. Convergent and divergent validity also showed significant correlations.
The result of the present study showed that the new version of quality of life scale based on choice theory could be confirmed. The good level of reliability, fairly goodness of fit indexes, and very good convergent validity support this idea.
选择理论作为一种精神病理学模型，从基因和普遍意义上假定了五种基本需求。因此，每个人的幸福率和生活质量取决于其需求得到满足的数量。尽管已经构建了一些量表来评估基本需求，但它们提出了适用于所有人的统一需求。
本研究旨在构建一个新的量表，即基于选择理论的生活质量量表（QOLSCT），该量表考虑了每个人的个性化需求。
采用整群抽样法，选取了600名研究生（49%为女性，51%为男性）。150名参与者还填写了SF-36和GHQ，80名参与者在四周后再次填写了QOLSCT。
克朗巴哈系数、分半信度和重测信度（1个月）得分依次为0.78、0.75和0.92。各项目与总分的相关性在0.36至0.72之间，所有P值均≥0.0001。验证性因素分析显示拟合优度指数值令人满意，RMSEA、CFI、NFI和GFI分别为0.05、0.99、0.99和0.99。收敛效度和区分效度也显示出显著相关性。
本研究结果表明，基于选择理论的新版本生活质量量表可以得到验证。良好的信度水平、相当不错的拟合指数以及非常好的收敛效度支持了这一观点。
