Chinese Center of Health Education Beijing China Abstract Objective To establish an assessment system to evaluate individual health literacy regarding respiratory infectious diseases by selecting its indexes confirming indexes weights and combining with a comprehensive sustainable index model. Methods A quota sampling was adopted on considering factors including participant s gender age and education background. 515 adults in Beijing took part in the survey conducted by computer assistant. Indexes were selected from original items by difficulty discrimination reliability and validity test. Besides normalization method and variation coefficient approach were applied to identify subjective weights and objective weights. Finally the assessment system was established with the comprehensive index model. Results 39 indexes which constitute of 3 aspects namely knowledge behavior or behavioral intention and relevant skills were selected to evaluate health literacy regarding respiratory infectious diseases. Difficulty coefficients of all indexes ranged from 0. 5 to 0. 9 and discrimination coefficients were all indexes were above Also the Cronbach s alpha coefficients were and for the three aspects respectively. After assessment system established by adding weights to indexes and aspects the system demonstrated good internal consistency reliability with a Cronbach s alpha of As for conduct validity 3 factors were extracted from all indexes which explained % of variance of the system accumulatively with KMO = and the 3 factors well fitted on confirmatory factor analysis IFI = TLI = CFI = RMSEA = Conclusions The assessment system with good reliability and validity meets aims of the study and can be well applied to evaluate the status of health literacy regarding respiratory infectious diseases.
