title: Interrater reliability of the Supports Intensity Scale (SIS).
abstract: The interrater reliability of the Supports Intensity Scale (SIS) was investigated under the condition that interviewers had to have been trained and/or experienced in its administration and scoring. Both corrected and noncorrected Pearson's product-moment coefficients were generated to assess interinterviewer, interrespondent, and mixed interrater reliability. The correlation coefficients for the SIS Support Needs Index Score and SIS subscale scores were considerably higher than coefficients reported in the SIS Users Manual that were derived from a similar study conducted with untrained, inexperienced interviewers.
