Social validity of primary prevention plans is assessed using the Primary Intervention Rating Scale, an adapted version of the Intervention Rating Profile‑15. The study aims to provide initial evidence for the reliability and structural validity of the Primary Intervention Rating Scale. The Primary Intervention Rating Scale proved to be a one‑factor, highly reliable instrument whose scores replicated across elementary, middle, and high schools and were positively associated with treatment integrity at the school‑site level. Limitations and future directions are discussed.
.This study provides initial evidence for the reliability and structural validity of scores from the Primary Intervention Rating Scale (Lane, Robertson, & Wehby, 2002), an adapted version of the Intervention Rating Profile-15 (Witt & Elliott, 1985) designed to assess faculty's perceptions of social validity of primary prevention plans prior to intervention onset. Results indicated the Primary Intervention Rating Scale is a one-factor instrument, with high internal consistency and utility. These results were found to replicate across educators from elementary, middle, and high schools. In addition, there was a significant, positive relation between social validity and treatment integrity when examining data at the school-site level. Limitations and future directions are offered.
