Abstract

Objective:To test the reliability of BMDC-NPTB-CR. Method: 182 elderlies were tested with the BMDC-NPTB-CR. Test-retest reliability and internal consistency of the scale were calculated. Result:70% of the items in BMDC-NPTB-CR were moderate in difficulty. The correlation between total score and subscores were in 0.50～0.88(P0.001),Cronbach alpha=0.75, with that of the subscales in 0.77～0.81,which indicated good internal consistency. The test-retest reliability of the total score was 0.93(P0.01),that of the subscores were in 0.6～0.9.Conclusion:BMDC-NPTB-CR has good reliability.
