Abstract:
Objective:To develop and examine the reliability and validity of the adolescent health literacy evaluation scale under public health emergencies (AHLES-PHE) in junior middle school students.Methods:The initial version of AHLES-PHE was formed by combining the characteristics of public health emergencies and adolescent health literacy.The expert version of AHLES-PHE was formed by two rounds of Delphi expert consultation.Totally 1 729 adolescent students from three junior middle schools in Changzhou City were tested.The formal version of AHLES-PHE was formed through item analysis and factor analysis (structural validity). The content validity of the formal version of AHLES-PHE was evaluated by specialist analysis and sensibility analysis, and its correlation validity with the everyday health information literacy (EHIL) was tested.The internal consistency reliability, parity split-half coefficient and test-retest reliability were calculated.Results:(1)Item analysis: the correlation coefficient between the scores of each item and the total score of AHLES-PHE expert version was 0.420 to 0.722 ( P<0.01), and the CR of decision value was 10.140 to 66.980 ( P<0.01). (2)Validity analysis: the formal version of AHLES-PHE with 45 items and 8 factors was obtained by exploratory factor analysis.The 8 factors could explain 61.30% of the total variation.The fitting indexes of the confirmatory factor analysis model were χ2/ df=3.325, RMSEA=0.052, GFI=0.853, CFI=0.912, TLI=0.904, NFI=0.880.Sensibility analysis of the formal version of AHLES-PHE showed the Cronbach's α ranged from 0.957 to 0.958.The correlation coefficient between the total score of AHLES-PHE formal version and the total score of EHIL was 0.340 ( P<0.01). (3)Reliability analysis: the Cronbach's α coefficient and parity split-half coefficient of the formal version of AHLES-PHE were 0.958 and 0.975, respectively.The test-retest reliability of the formal version of AHLES-PHE was 0.753 ( P<0.01). Conclusion:The formal version of AHLES-PHE developed in this study has good reliability, structural validity and content validity, and the correlation validity with EHIL is common.This scale has a certain degree of applicability to the assessment of health literacy for junior middle school students under public health emergencies.
