Quality Assessment of the 2023 Health Literacy Survey for Residents in Jiangsu Province

Objective: To evaluate the predictive effectiveness of survey duration, questionnaire rejection rates, and quality control indicators, using the 2023 health literacy monitoring data from Jiangsu Province as an example. This research aims to provide insights for improving the quality of health literacy monitoring among residents. Methods: Based on the Jiangsu Province Health Literacy Monitoring Management System, we selected the process information related to all questionnaires used in the 2023 health literacy monitoring survey in Jiangsu Province as the study subject. We used rank-sum tests to compare differences in survey duration. Additionally, we evaluated five quality control indicators: sensitivity, specificity, yield index, positive predictive value, and negative predictive value. These indicators were used to assess issues such as abnormal family member counts within the age range of 15–69 years old, and inconsistencies in gender data.
