Psychometric evaluation of the Chinese version of the Revised Spontaneity Assessment Inventory (SAI-R-C)

Abstract

The study aims to test the reliability and validity of the Chinese version of the Revised Spontaneity Assessment Inventory (SAI-R-C) and the correlation between spontaneity and mental health. Data were collected from various samples of Chinese college students and employees. The SAI-R-C, the Subjective Well-being Scale, and the Chinese version of the Outcome Rating Scale were simultaneously administered at a four-week interval to test the reliability and validity of the SAI-R-C. The results indicated that the SAI-R-C was unidimensional and its internal consistency coefficient was .96. The test-retest reliability of the SAI-R-C was .74 within a two-week interval. Significantly positive correlations were found between spontaneity and life satisfaction, positive emotions, overall well-being, and the Outcome Rating Scale, whereas a negative correlation was found between spontaneity and negative emotions. Overall, the SAI-R-C is a reliable and valid measure for assessing spontaneity in China.
