The Reliability and Validity of Chinese Version of Free Will and Determinism Plus Scale
The Free Will and Determinism Plus (FAD+) is a widely-used questionnaire in research of belief in free will and has been translated into different languages. The present study aimed to assess the psychometric properties of the Chinese version of FAD+. We first translated and back-translated the FAD+, and then surveyed 1474 young adults, with 1333 valid data, in different sites in China. The first half of the data (n = 590) were used for items analysis, which resulted in the removal of 3 items. The rest of the data (n = 743) were used to assess the reliability, construct validity, and factor structure of the 24-item Chinese FAD+. Results revealed that the Chinese FAD+ are relatively reliable (α [.60 ~ .78], ω [.60 ~ .78], test-retest correlation [.54~ .59]) and valid (four-factor structure). Our results suggest that the 24-item FAD+ could be potentially useful for future studies that will use a similar population as ours.
