“…This may be due, in part, to the idea that researchers generally view self-report as unreliable (Dunning et al, 2004). Further, often children in particular are viewed as unreliable self-reporters in assessments of complex psychological constructs (e.g., hopelessness, anxiety and worry; Kazdin, Rodgers, & Colbus, 1986; Perez, Ascaso, Massons, & Chaparro, 1998; Schniering, Hudson, & Rapee, 2000). This view is often held despite a wealth of evidence that children can provide reliable and valid self-reports of complex constructs and behaviors (e.g., Achenbach & Rescorla, 2001; Hunsley & Mash, 2007; Mash & Hunsley, 2005).…”
