Abstract

Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurodevelopmental condition typically first diagnosed in children who exhibit substantial inattention and/or impulsivity and hyperactivity (APA, 2013). ADHD can manifest similarly to other childhood conduct problems, such as Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD; Kuhne et al., 1997) but is distinct. The diagnostic process for these disorders often includes ratings from adults in the child’s life to assess behavior across settings (Rimvall et al., 2018). However, although the information gathered from these various raters is intended to better elucidate the potential diagnosis, these somewhat subjective measures allow for the possibility of rater bias (Emser et al., 2018). Researchers have identified negative halo effects in adult ratings of ADHD (Jackson & King, 2004; Hartung et al., 2006; Murray et al., 2007). Specifically, raters erroneously rated a child’s ADHD symptoms higher when the child exhibited conduct problems (Jackson & King, 2004), suggesting that in the presence of ODD symptoms adults assume ADHD symptoms are also present. So, given all this, my Master’s thesis is going to replicate and extend past research in an effort to examine negative halo effects in parent ratings of ADHD, ODD, and CD. Parents in the Cedar Valley area will read one of three vignettes portraying a child with either symptoms of only ADHD, ODD, or CD and then respond to scales measuring their endorsement of the DSM-5 criteria for those disorders and disruptive behaviors.
