Abstract

OBJECTIVES: The objective of the study was to establish a cut-off point for high dysphonia risk in children using the Child Dysphonia Risk Screening Protocol (DRSP-C). METHODS: Through a preliminary study, voice recordings of 59 children (4-12 years of age) were collected during an auditory-perceptual analysis using the Consensus Auditory-Perceptual Evaluation of Voice protocol. Thirty of the patients had voice disorders (patient group), and 29 did not (control group). A risk score for dysphonia was then calculated, and data were compared between groups. The relationship between overall degrees of deviation and questionnaire scores was analysed. The questionnaire’s validity was verified from the area under the Receiver Operating Characteristic (ROC) curve, and cut-off points were obtained based on diagnostic criteria for screening procedures. RESULTS: The DRSP-C score was found to be higher for the patient group, as was the partial score for vocal behaviour. No correlation was found between overall degrees of dysphonia and questionnaire scores. The area under the ROC curve was measured as 0.678, denoting limited diagnostic capacity. The cut-off point was set at 16.50. Thus, above this value, dysphonia risk is higher. CONCLUSION: A cut-off point for high dysphonia risk was calculated. The DRSP-C proved to be a promising tool for children’s clinical vocal and health promotion and should be used in conjunction with General Dysphonia Risk Screening.
