“…Less time-intensive, yet comprehensive, instruments have been developed, which examine mother-infant interactions during a variety of spontaneous and fun tasks, like free play [Paavola, Kemppinen, Kumpulainen, Moilanen, & Ebeling, 2006; Vliegen, Luyten, & Biringen, 2009; Dolberg, Feldman, Keren, 2010; Leerkes, 2011], or during more routine and structured tasks, like clean-up [Schneider-Rosen & Rothbaum, 1993; Gardner, Sonuga-Barke, & Sayal, 1999; Pears & Ayres, 2000; Kok et al 2012]. These instruments provide measurements of maternal sensitivity, intrusiveness, warmth, hostility, disengagement, and structured limit-setting [Pears & Ayres, 2000; Vliegen et al, 2009; Kaitz, Maytal, Devor, Bergman, & Mankuta, 2010] and have demonstrated concurrent validity [Kaitz et al, 2010; Vliegen et al, 2009], convergent validity [Caldera & Hart, 2004; Leerkes, 2011], and predictive validity [Paavola, et al, 2006; Kok et al, 2012] with a variety of child and parental outcomes.…”
