Objectives:
Parental questionnaires are important tools in the evaluation of auditory and language skills of very young children affected by sensorineural hearing loss. One of these instruments is the Production on Infant Scale Evaluation (PRISE). The purposes of this study were to adapt and validate the PRISE on Italian children with normal hearing; and to obtain normative data.
Methods:
A back translation technique was used to adapt the Italian version of PRISE. The PRISE was submitted to parents of 234 normal children aged between 3 and 18 months of life. All of them passed local universal newborn hearing screenings and they presented no audiological risk factors.
Results:
The PRISE internal reliability (Cronbach's alpha) was 0.87. Split-half reliability indexes were λ(4) = 0.89 and λ(6) = 0.89. Corrected item-total correlation coefficients were significant for all items. The correlation of PRISE with a modified Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS), collected for convergent validity measurement purposes, was good (r = 0.743). A positive correlation of PRISE scores with age was found, reflecting on the age-dependence of pre-verbal skills.
Conclusion:
These findings demonstrate high reliability and convergent validity of the Italian PRISE version. This questionnaire constitutes a robust tool for assessing early language development in infants and toddlers with normal hearing. It seems particularly sensitive to the normal language development in the first years of life, which can be very useful for early rehabilitation of hearing loss.
