Validation of a questionnaire developed to evaluate a Spanish eHealth paediatric web for parents.
ABSTRACT
Background:
Parents need information about their children’s symptoms and the Internet is a major resource that may serve as a convenient repository of health information for parents. There is an urgent need for health professionals to provide parents with evidence-based child health websites. There is also a need for instruments to measure their accessibility, usability, usefulness and confidence building.
Objective:
The main aim of the present study was to develop a questionnaire for measuring users’ evaluation of different aspects of a Spanish paediatric Health web for parents. We further sought to evaluate the content validity and psychometric reliability of our instrument.
Methods:
After a review of the literature we designed an initial 40-qualitative item pilot survey, following the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) guidelines. We performed a content validation study by experts review and the survey was then administered via web. 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 Method.
Results:
Content validation of the questionnaire by experts was considered as excellent. The pilot web survey was completed by 516 volunteer participants. Exploratory factor analysis allowed us to exclude 26 of the 40 initial items. Confirmatory factor analysis of the resultant 14-item questionnaire confirmed the five initial domains previously 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.
Conclusions:
Effectiveness and reliability are essential aspects of eHealth interventions and should be properly evaluated. Although our research has limitations, we can assume that our questionnaire is appropriate for the evaluation of an eHealth Spanish paediatric web for parents.
