Factorial validity of the Conners' Parent Rating Scale-revised: short form with psychiatric outpatients.
To assess the factorial validity of the 27-item Conners' Parent Rating Scale-Revised: Short Form (CPRS-R:S; Conners, 1997), 100 (50%) male and 100 (50%) female psychiatric outpatients between 5 and 16 years old were rated by a parent. A confirmatory factor analysis of the 18 item ratings from the CPRS-R:S Oppositional, Cognitive Problems, and Hyperactivity scales provided only tentative support for scoring these scales as Conners (1997) recommended. However, an exploratory principal-axis factor analysis with all 27 item ratings found 2 dimensions: 1 dimension was composed of the 6 items in the Oppositional scale, and other dimension contained the remaining 21 items. An attention deficit hyperactivity disorder (ADHD) Total Symptoms scale was constructed by summing the ratings for these 21 symptom ratings, and this scale was found to be as effective as the Hyperactivity scale was in discriminating between youth who were and were not eventually diagnosed with an ADHD. We discuss the results as providing an alternate way of scoring the CPRS-R:S to screen for an ADHD in child and adolescent psychiatric outpatients.
