“…The CCQ serves this function well as a great deal of research has confirmed the reliability and validity of this tool (e.g., Block, Block, & Morrison, 1981; Caspi et al., 1992; Dollinger, 1992; John, Caspi, Robins, Moffitt, & Stouthamer‐Loeber, 1994; Parker & Stumpf, 1998; Weir & Gjerde, 2002). Furthermore, this instrument has commonly been used with mothers as a way to assess child personality (e.g., Caspi et al., 1992; John et al., 1994; Wessels, Lamb, Hwang, & Broberg, 1997; van Aken & van Lieshout, 1991; van Lieshout, De Meyer, Curfs, & Fryns, 1998).…”
