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 and related developmental disabilities (ID/DD) receiving services from a state ID/DD agency were examined. Pearson's product moment coefficients were considerably higher than coefficients reported in a previous study conducted with untrained interviewers. In Study 1, the interrater reliability of the P&A Scale was investigated when interviewers were trained in SIS administration and scoring. 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).
