“…Even if the majority of child welfare reports are not substantiated (Kugler et al, 2019), these nonsubstantiated cases may show similar adversities that, although short of the substantiation criteria, put them at risk for further maltreatment and, thus, for problematic developmental outcomes (Hussey & Guo, 2005;Kohl, Jonson-Reid, & Drake, 2009;Kugler et al, 2019). However, there is emerging consensus that maltreatment is a complex construct requiring reliable and valid measurement tools, developed through advanced statistical techniques (Brumley, Brumley, & Jaffee, 2019;English, Bangdiwala, & Runyan, 2005;Gabrielli & Jackson, 2019;Gabrielli, Jackson, Tunno, & Hambrick, 2017;Jackson, Gabrielli, Fleming, Tunno, & Makanui, 2014). As such, we aim to describe the development of an instrument to assess child maltreatment, specifically designed to be used by professionals in CPS services.…”
