Impact of the Protection and Advocacy subscale on the factorial validity of the Supports Intensity Scale-Adult Version.
Product Description:
Three separate studies were undertaken to examine the reliability and validity of the Supplemental Protection and Advocacy Scale (P&A Scale) of the Supports Intensity Scale (SIS). In Study 1, the interrater reliability of the P&A Scale was investigated when interviewers were trained in SIS administration and scoring. Pearsons product moment coefficients were considerably higher than coefficients reported in a previous study conducted with untrained interviewers. In Study 2, the reliability (internal consistency, standard error of measurement, and interrater reliability) and validity (content and construct validity) of the P&A Scale when administered by trained interviewers with a sample of individuals with intellectual disability receiving services from a state ID/DD agency was examined. Results suggest strong reliability and validity of the P&A Scale, comparable to other domains of the SIS.
