Can You Understand Your Child? Reliability and Validity of a Parent Questionnaire: The Intelligibility in Context Scale: Italian.

Introduction: The Intelligibility in Context Scale (ICS) is a parent-report scale by which parents can rate their child's functional speech intelligibility according to seven different communicative partners. Translations, linguistic adaptations, and psychometric and norming data for ICS have been achieved in different languages.

Objective: To evaluate the psychometric properties of the Italian version of the ICS (ICS-I) in terms of internal consistency, test-retest reliability, criterion validity (correlation with speech measures), and construct validity, and to investigate potential differences between mothers' and fathers' subjective ratings in ICS-I.

Normative data and construct validity of a cross-linguistic functional speech outcome, the Intelligibility in Context Scale: Italian (ICS-I).

Objectives: The Intelligibility in Context Scale (ICS) is a parent-report scale, world-wide translated and widely validated, by which parents can rate their child's functional speech intelligibility according to seven different communicative partners. The study aimed to report and discuss the normative data of the Italian version of ICS (ICS-I) in Italian-speaking preschool children, and to investigate whether the age influences the ICS-I scores (construct validity). Socio-economic status (SES) of the family were investigated and compared to parents' ratings on child's speech intelligibility.
