Abstract
BACKGROUND: There is an increasing need for an instrument, which allows to quickly and reliably assess the auditory behaviour of infants and toddlers. SCIENTIFIC QUESTION AND OBJECTIVE: The objective of this study was to develop and validate the "LittlEARS Hearing Questionnaire", a tool for assessing auditory behaviour in children up to 24 months of age. METHODS: Questionnaire construction followed the principles of classical test theory. The psychometric properties of 45 questions on infant auditory behaviour were examined in a sample of 218 parents of normal hearing infants up to age 24 months. Parental responses also served for computing normative values of the development of early auditory behaviour by regression analysis. RESULTS: The final questionnaire contains 35 items, to be answered with either "yes" or "no". The sum of "yes"-answers yields an overall score, which can be compared to age-related normative values in order to appraise the age-appropriateness of the infant's auditory behaviour. The following scale characteristics have been found with the above sample: internal consistency: Cronbach's Alpha = 0.96; reliability: split-half r = 0.88; predictive accuracy: Guttman's Lambda = 0.96; correlation between overall score and age of the children: r = 0.91. CONCLUSION: The "LittlEARS Hearing Questionnaire" is suitable for the quick assessment of a little child's hearing behaviour, e. g. at physical examinations, at the postnatal hearing screening, or when evaluating rehabilitative measures.
