“…Three topics are addressed in this commentary. First, while Gastelle and Kerns (2022) apply the relevant psychometric criteria of convergent, construct, and discriminant validity, this comment will focus on the need for future research to also address predictive validity, as studies linking infancy and early childhood to attachment in middle childhood appear to have been the focus in only 3 of the 67 papers reviewed by Gastelle andKerns (2022) (i.e., Miller et al, 2019;O'Connor et al, 2019;Steele & Steele, 2005). Furthermore, only one study has looked prospectively at how attachment in middle childhood may foreshadow later patterns of attachment in adolescence (Vaughn et al, 2016), and one study has considered young adult romantic relationships as related to prior peer-related attachment in middle childhood (Grossman et al, 2005).…”
