PURPOSE: To examine whether the two-item version (CD-RISC2) of the Connor-Davidson Resilience Scale (CD-RISC) has adequate internal consistency and construct validity, as well as significant correlation with the full scale, and to provide normative data for the CD-RISC and the CD-RISC2 in a Chinese general population in Hong Kong.

METHODS: In total, 10,997 randomly selected participants aged ≥20 years completed the Chinese version of the CD-RISC (including the 2 items of the CD-RISC2), the Patient Health Questionnaire, Family Harmony Scale, Family APGAR, and CAGE Questionnaire. Internal consistency and convergent and discriminant validity of the CD-RISC and CD-RISC2 were assessed.

RESULTS: Cronbach's α for CD-RISC and CD-RISC2 was 0.97 and 0.79, respectively. CD-RISC2 was associated with the 25-item version of the CD-RISC (r = 0.88), depressive symptoms (r s = -0.18), family harmony (r = 0.20), family functioning (r = 0.27) and was not associated with alcohol consumption (r = 0.05). The mean score for the CD-RISC and CD-RISC2 was 59.99 (SD = 13.92) and 5.03 (SD = 1.37), respectively. Men, younger individuals, and those with higher education or higher household income reported higher resilience levels.

CONCLUSIONS: The Chinese version of the CD-RISC2 was demonstrated to be a reliable and valid measure in assessing resilience among the general population in Hong Kong.
