“…EIS-TR Externalizing and Attention/Academic Issues subscales also have strong correlations with similar BASC-3 scales ( r s = .72 and .67, respectively; Stormont et al, 2022). Moreover, beginning-of-year EIS subscale scores predicted end-of-year school record data (e.g., discipline referrals, suspensions, attendance, achievement scores) across development (Herman, Reinke, Huang, et al, 2021; Reinke et al, 2022; Thompson et al, 2021). The EIS-SR is also sensitive to change; for instance, over a 3-year, nine-time point period, students in schools implementing the EIS reported a significant decline in the slope of total symptoms, and students in schools with lower fidelity to the model were more likely to have a pattern of worsening EIS problems (Reinke et al, 2021).…”
