Results The Dementia Caregivers' Nursing Ability Scale consisted 5 subscales and 36 items, the exploratory factor analysis identified five principal factors which explained 79.44% of the total variance. The item content validity index ranged from 0.857 to 1, the scale content validity index was 0.985. The Cronbach's α coefficient of the scale was 0.936, the split reliabilit was 0.970, and the test-retest reliability was 0.980. Conclusion Dementia Caregivers' Nursing Ability Scale has good reliability and validity, which can be used as a tool to measure the dementia caregivers' nursing ability.
