“…Our focus on the TMCQ, in particular, due to its importance for studies of development and psychopathology in middle childhood, the peak years of onset for common psychopathology and a critical period for child development (Shiner, 2021), and the shortage of validation studies of it. The TMCQ has been used for multiple studies of cognitive, personality, and neural development (Affrunti et al, 2014; Affrunti & Woodruff-Borden, 2015; Ato et al, 2020; Inuggi et al, 2014), as well as developmental psychopathology (Karalunas et al, 2019; Kotelnikova et al, 2015, 2017; Nigg et al, 2020; Rutter & Arnett, 2021). The TMCQ is designed to evaluate temperament in the regulation–reactivity model from ages 7 to 10, although there is evidence that such questionnaires can be used and are used outside their originally intended age ranges (Soto & John, 2014) and can be completed by adult raters or by self-report (Simonds & Rothbart, 2004, 2009).…”
