“…Second, with regard to psychometric properties, teacher versions of both instruments have evidence for adequate internal consistency and test-retest reliability, though the BESS appears marginally stronger in these areas (Feeney-Kettler, Kratochwill, Kaiser, Hemmeter, & Kettler 2010;Harrison, Vannest, Reynolds, 2013;Stone, Otten, Engels, Vermulst & Janssens, 2010). The BESS has demonstrated strong concurrent validity with theoretically related instruments such as the BASC-2 (Kamphaus, DiStefano, Dowdy, Eklund, & Dunn, 2010), Direct Behavior Ratingsingle-item scales (Miller et al, 2015), and Social Skills Improvement System-performance screening guide (Miller et al, 2015). The teacher version of the SDQ has demonstrated concurrent validity with a number of broad and specific mental health diagnostic screeners (see Stone et al, 2015 for a review) but has relatively fewer examinations as a school-based universal screener.…”
