Parent and Teacher SNAP-IV Ratings of Attention Deficit Hyperactivity Disorder Symptoms: Psychometric Properties and Normative Ratings from a School District Sample
Bussing, Regina; Fernandez, Melanie; Harwood, Michelle; Hou, Wei; Garvan, Cynthia Wilson; Eyberg, Sheila M.; Swanson, James M.
Assessment, v15 n3 p317-328 2008
To examine Swanson, Nolan, and Pelham-IV (SNAP-IV) psychometric properties, parent (N = 1,613) and teacher (N = 1,205) data were collected from a random elementary school student sample in a longitudinal attention deficit hyperactivity disorder (ADHD) detection study. SNAP-IV reliability was acceptable. Factor structure indicated two ADHD factors and an oppositional defiant disorder (ODD) factor. Parent and teacher scores varied by gender and poverty status (d = 0.49-0.56) but not age; only teacher scores varied by race (d = 0.25-0.55). Screening and diagnostic utility was evaluated with likelihood ratios (LRs) and posttest probabilities. Parent SNAP-IV scores above 1.2 increased probability of concern (LR greater than 10) and above 1.8, of ADHD diagnosis (LR greater than 3). Teacher hyperactivity/impulsivity scores above 1.2 and inattention scores above 1.8 increased probabilities of concern only (LR = 4.2 and greater than 5, respectively). Higher teacher scores for African American children and race differences in measurement models require future study. (Contains 5 tables and 1 figure.)
