The effects of measurement method on levels of unrealistic optimism for developing diabetes were examined in 323 UK adults. A mixed factorial design comprised direct and indirect measures of unrealistic optimism as the within-subjects variable, and between-subjects manipulations of the order of direct versus indirect assessment, the order of self-other comparison, the number of response options used and the polarity of the ratings. More unrealistic optimism was obtained using the direct method and using unipolar scales, and/or with the self-other order in the indirect method. The results indicate that levels of unrealistic optimism depend on its assessment method.
在323名英国成年人中研究了测量方法对患糖尿病不切实际乐观水平的影响。混合因子设计包括将不切实际乐观的直接和间接测量作为被试内变量，以及被试间对直接与间接评估顺序、自我与他人比较顺序、使用的反应选项数量和评分极性的操纵。使用直接方法、单极量表和/或间接方法中的自我与他人顺序时，获得了更多不切实际的乐观情绪。结果表明，不切实际乐观水平取决于其评估方法。
