Development of the Drooling Infants and Preschoolers Scale (DRIPS) and reference charts for monitoring saliva control in children aged 0–4 years
2018
Abstract Objectives To develop and validate a parent questionnaire to quantify drooling severity and frequency in young children (the Drooling Infants and Preschoolers Scale – the DRIPS). To investigate development of saliva control in typically developing young children in the age of 0–4 years. To construct sex-specific reference charts presenting percentile curves for drooling plotted for age to monitor the development of saliva control in infancy and preschool age. Study design The DRIPS was developed consisting of 20 items to identify severity and frequency of drooling during meaningful daily activities. Factor analysis was performed to test construct validity. A piecewise logistic regression was followed by a piecewise linear regression to construct sex-specific reference charts. Results We obtained 652 completed questionnaires from parents of typically developing children. The factor analysis revealed four discriminating components: drooling during Activities , Feeding , Non nutritive sucking, and Sleep . To illustrate the development of saliva control, eight sex-specific reference curves were constructed to plot the scores of the DRIPS by age group, at the 15th, 50th, 85th and 97th percentile. About 3–15% of the preschoolers in our cohort did not acquire full saliva control at the age of 4 years. Conclusions With the DRIPS it is possible to validly compare and visualize the development of saliva control in an individual infant or preschooler and allow clinicians to timely initiate individually targeted interventions if children outperform.
