Application of Delphi method to building a visual literacy evaluation system for pupils / 预防医学

ABSTRACT

Objective @#To construct a visual literacy evaluation system for pupils by Delphi expert consultation method（Delphi method）. @*Methods @#The visual literacy evaluation indices for pupils were preliminarily constructed through literature review. Twenty experts in relevant fields were invited and the visual literacy evaluation system for pupils was established by two rounds of expert consultation based on Delphi method. @*Results @# The average age of 20 experts was（48.35±5.79）years old,of which 19 experts had senior titles,and 17 experts had master's degree or above. The enthusiasm of the experts in two rounds of consulting was both 100.00%. The average authoritative coefficient（W）of the experts was 0.88. For the first consulting round,the W of importance scores from experts was 0.91（P<0.01）;the W of operability scores from experts was 0.89（P<0.01）,which indicated satisfactory consistency. For the second consulting round,the W of importance scores from experts was 0.79（P<0.01）;the W of operability scores from experts was 0.77（P<0.01）,which also indicated satisfactory consistency. The finalized visual literacy evaluation system for pupils after two rounds of expert consultation included three primary indices（eye care knowledge literacy,eye care attitude literacy and eye care behavior literacy）,six secondary indices（basic knowledge,eye care behavior,eye care attitude,eye care willingness,bad eye care behavior and eye protection）and 40 tertiary indices（≥5.0 of eyesight among normal people,always wearing glasses due to poor eyesight and so on）. @*Conclusion @#The experts who participated in the construction of visual literacy evaluation system for pupils had strong professional representativeness,high enthusiasm,high authority and good coordination,and the evaluation system can be used for evaluating pupils visual literacy.
