Comparison of the ECOHIS and short-form P-CPQ and FIS scales.

Background The development of short-form versions of child oral–health-related quality of life (OHRQoL) scales has resulted in two closely related sets of measures. We set out to compare the properties and responsiveness of the Early Childhood Oral Health Impact Scale (ECOHIS – both “child” and “family” versions) and short-form Parental-Caregiver Perceptions Questionnaire (P-CPQ) and the Family Impact Scale (FIS) measures among New Zealand children with early childhood caries who underwent treatment under general anaesthesia (GA).
