“…The revision was aimed at evaluating a wider range of temperamental dimensions by providing 14 subscales from which three overarching factors typically emerge: Surgency (approach, vocal reactivity, high intensity pleasure, smiling and laughter, activity level, and perceptual sensitivity), Negative Affectivity (sadness, distress to limitations, fear, and low falling reactivity), and Orienting/Regulatory Capacity (low intensity pleasure, cuddliness, duration of orienting, and soothability). To date, reliability and validity of the questionnaire have been supported in Gartstein and Rothbart's work (2003), in cross-cultural studies comparing US and Russian infants' temperament (Gartstein, Peleg, Young, & Slobodskaya, 2009;Gartstein, Slobodskaya, & Kinsht, 2003;Gartstein, Slobodskaya, Putnam, & Kinsht, 2009), in longitudinal research predicting preschool temperament and toddler behavior problems (Putnam, Rothbart, & Gartstein, 2008;Gartstein et al, 2010), and in recent investigations of convergent validity of the IBQ-R in relation to observation-based indices of temperament (Gartstein & Marmion, 2008;Parade & Leerkes, 2008).…”
