“…Several studies have adopted the five-item SCS for research purposes, which differs only one item from the 2019 TIMSS SSBS, providing evidence for its robust validity and reliability (Anderman, 2002; Bonny et al, 2000; Furlong et al, 2011; Galliher et al, 2004; Kim et al, 2019; Law et al, 2022; Liu et al, 2021; O’Brennan & Furlong, 2010; Patte et al, 2021; Waters et al, 2010). The internal consistency reliability of the five-item SCS has been found to range from .77 (Bonny et al, 2000; Galliher et al, 2004) to .86 (Furlong et al, 2011), which means it can be considered a reliable instrument for measuring the intended construct in research.…”
