Abstract Background Parasitic diseases remain a serious public health problem in China. Health education aimed at disseminating health-related knowledge and promoting healthy behaviours, plays a crucial role in the prevention and control of parasitic diseases. This study aims to develop a tool to measure the parasitic disease health literacy of residents in China. Methods Scale development was based on qualitative and quantitative methods. Qualitative method included focus group discussions and Delphi consultations. A methodological design with multistage sampling and a pilot study was used to evaluate the questionnaire. The scale’s reliability was tested using Cronbach’s α and split-half reliability, while its construct validity was assessed using confirmatory factor analysis. The scale’s passing score was determined using the receiver operating characteristic curve. A cross-sectional survey was conducted in six districts of the prefecture of Jiangsu and residents aged 14–69 years in the participating townships were randomly selected based on their location. Results The health literacy indicator system for parasitic diseases included 3 first-level, 9 s-level and 23 third-level indicators. The 23-item questionnaire demonstrated good internal consistency (Cronbach’s alpha = 0.774) and split-half reliability (Spearman-Brown coefficient = 0.778). The questionnaire’s passing score was 60. A total of 990 valid questionnaires were collected from participants in three cities. The percentage of participants with health literacy regarding parasitic diseases was 15.8%. Their scores were influenced by age, income, employment, and educational level. Conclusions Health literacy of parasitic diseases is an integrated indicator rather than just knowledge or behavior information. The correlation between knowledge and behavior is weak. The capacity for healthy behavior of parasitic disease is associated with the location and culture of the city. For neglected diseases, it is important for people to talk positively about their behaviors with a doctor.
