Objectives:
We tried to develop a more concise health literacy scale for Chinese older adults.
Methods:
A draft scale based on the Health Literacy Questionnaire (HLQ) was developed, and revised by experts. We conducted a pilot study to test the readability and establish a standard inquiry method within 10 residents. We tested the validity and internal consistency using a field test with 3,739 participants.
Results:
Overall standardized Cronbach's α of Chinese Health Literacy Scale (CHLS) was 0.86 and that of each dimension ranged from 0.69 to 0.81. Nearly all dimensions had satisfactory factor loadings (0.33-0.98). The correlation coefficient between the score of each item and its dimension ranged from 0.59 to 0.92.
Conclusions:
The performance of CHLS was almost the same as the HLQ but more concise. It might play a role in reflecting the health literacy of older adults in China and further promoting their health.
