Abstract

A questionnaire, the Verbal Behavior Assessment Scale, was developed to assess the communicative functions of individuals with developmental disabilities and severe mental handicap. To assess its psychometric characteristics, the questionnaire, comprising 15 items, was administered to pairs of caregivers of 115 participants. Exploratory factor analysis, involving 11 more participants, revealed satisfactory evidence concerning the distinction of three different communicative functions with the present sample. The questionnaire had good levels of interrater reliability and internal consistency.
