Reliability
a. Test-Retest/Reproducibility:
Reported 1
b. Internal Consistency:
Reported 1
The test-retest reliability of the PCS-12 summary measures was 0.890 in the US and 0.864 in the UK. Coefficients of 0.760 in US and 0.774 in UK were observed for the MCS-12. Changes in scores between test and retest averaged less than 1 point for the 2 summary measures in both samples and 85.3% scored at the 2nd administration within the 95% confidence interval of the scores at the first administration for both PCS-12 and MCS-12.
Validity
a. Validity:
Reported 1
14 validity tests involving physical criteria ranged from 0.43 to 0.93 (median = 0.67). Relative validity estimates for the Mental Component Summary in 6 tests involving mental criteria ranges from 0.60 to 1.07 (median = 0.97).
