Eysenck Personality Questionnaire-Revised Short Scale for Chinese (EPQ-RSC)

The EPQ-RSC used in this study was revised from the Eysenck Personality Questionnaire Brief Scale (EPQ-RS) by Qian et al. (2000). It consisted of four subscales, including extraversion (E), neuroticism (N), psychoticism (P), and validity (L) subscales, with 12 items on each subscale. The test–retest reliability of the scale was reported to be 0.67 to 0.88 after three weeks; the split-half reliability was 0.51 to 0.77, and the internal consistency was 0.54 to 0.78. The correlations between the original scale and the Chinese version of the EPQ were 0.27 to 0.64 (only the P subscale was 0.27, less than 0.5), which shows good validity.
