Accept-ability was determined using a parental satisfaction survey.1061 children completed 2318 validated questionnaires.Scores were compared with normative sample, except forGross motor at 8 and 12 months, and Communication at12, 18 and 24 months, without differences to the previousChileans sample. In domain analysis, Cronbach's alpharanged from 0.36 to 0.80 and reached 0.74 to 0.81 for theoverall test. Strong positive correlation between the domainand overall score was obtained. Correlation between mostquestionnaires at different ages was positive and significant.Parental surveys show high satisfaction; parents werethankful for being able to monitor children's development.WB-ASQ-3 is a reliable and feasible screening system, par-ticularly when the test is taken as a whole, rather than by domains.
