Outline
To develop a knowledge, attitude, and behavior questionnaire on screen use among caregivers of children and to test its reliability and validity.
Based on the theory of “Knowledge-Attitude-Practice”, the initial questionnaire was formed through literature analysis, research group discussion, two rounds of Delphi expert consultation and pre-investigation. Through convenient sampling, 270 main caregivers of children aged 2 to 12 in Heilongjiang Province were selected for questionnaire investigation. Item analysis of the data was conducted, and internal consistency coefficient was used to analyze the reliability of the questionnaire. Exploratory factor analysis and content validity were used to evaluate the validity of the questionnaire.
The formal questionnaire consisted of 5 items on general information, 10 items on knowledge dimension, 7 items on attitude dimension, and 9 items on behavior dimension. The Item - Level Content Validity Index (I-CVI) ranged from 0.850 to 1.000. The Scale-Level Content Validity Index (S-CVI) was 0.808, and the Scale-Level Content Validity Index/Average (S-CVI/Ave) was 0.982. The factor loadings for all items were greater than 0.4, and the contribution rate of cumulative variance was 63.346%, indicating good validity. The Cronbach’s α coefficient of the questionnaire overall was 0.892, and the Cronbach’s α coefficient of the three dimensions ranged between 0.738 and 0.886, with good reliability.
The questionnaire has good reliability and validity, and can be used as an evaluation tool for the level of knowledge, attitude, and behavior of caregivers of children.
