Validation of a Questionnaire Developed to Evaluate a Pediatric eHealth Website for Parents

Abstract

There is a need for health professionals to provide parents with not only evidence-based child health websites but also instruments to evaluate them. The main aim of this research was to develop a questionnaire for measuring users’ evaluation of the usability, utility, confidence, the well-child section, and the accessibility of a Spanish pediatric eHealth website for parents. We further sought to evaluate the content validity and psychometric reliability of the instrument. A content validation study by expert review was performed, and the questionnaire was pilot tested. Psychometric analyses were used to establish scales through exploratory and confirmatory factor analyses. Reliability studies were performed using Cronbach’s alpha and two split-half methods. The content validation of the questionnaire by experts was considered as excellent. The pilot web survey was completed by 516 participants. The exploratory factor analysis excluded 27 of the 41 qualitative initial items. The confirmatory factor analysis of the resultant 14-item questionnaire confirmed the five initial domains detected in the exploratory confirmatory analysis. The goodness of fit for the competing models was established through fit indices and confirmed the previously established domains. Adequate internal consistency was found for each of the subscales as well as the overall scale.

Consumers’ Attitude towards Sustainability in Italy: Process of Validation of a Duly Designed Questionnaire

“…The aim of this study was to show and discuss the validation process and the adaptation to the Italian context of a questionnaire on consumer knowledge and attitudes toward sustainability starting from a questionnaire already used in Europe [ 18 ]. Using a procedure largely described in the literature [ 25 , 26 , 27 , 28 ], the questionnaire was initially developed by experts and then revised on the basis of the results of a pilot test on consumers. The analysis of the data collected in the pilot phase on a group of 150 respondents, highlighted a series of inconsistencies that were corrected in the final version of the questionnaire.…”

“…The questionnaire validation protocol was designed following a procedure largely reported in the literature [ 25 , 26 , 27 , 28 ], applied in different settings, and assessing different topics and constructs. The procedure could be summarized as follow: the initial analysis for the identification of the domains of interest was normally carried out by the team that developed the questionnaire [ 29 ], then the validity of the items was assessed in consecutive stages by requesting individual experts to evaluate the content relevance and simplicity of individual items and the entire set of items (questionnaire) as a tool [ 30 , 31 , 32 ].…”

An instrument assessing attitudes and beliefs toward human papillomavirus vaccination

“…Then, the adequacy of the sample size was determined by the Kaiser‐Meyer‐Olkin statistic. A Kaiser‐Meyer‐Olkin value of ≥ .80 indicates high adequacy of sample size (Nievas Soriano et al., 2020). In this study, Kaiser‐Meyer‐Olkin in the exploratory factor analysis was .85.…”

A Field Investigation on Adaptive Thermal Comfort in an Urban Environment Considering Individuals’ Psychological and Physiological Behaviors in a Cold-Winter of Wuhan

“…Statistical tests were used to estimate the required sample value to calculate effect sample values for the questionnaire analysis. The estimate revealed that more than 110 responses were needed for each type, and over 220 in all to ensure the study's accuracy [67][68][69]. Thus, according to the estimation, the sample amounts were sufficient to perform an accurate and useful study.…”
