Abstract:
The primary purpose of this study was to examine the reliability and validity of the Children’s Interview for Psychiatric Syndromes-Parent Version (P-ChIPS). Reliability of the P-ChIPS was examined through interrater reliability (i.e., degree of agreement between raters) and internal consistency analyses. Concordant validity was explored by examining the agreement between the P-ChIPS and the Child and Adolescent Symptom Inventory (CASI). Convergent validity was examined by measuring the relationship between P-ChIPS-derived diagnoses and Nisonger Child Behavior Checklist (NCBRF) problem behavior and prosocial subscales.
The impact of IQ, language, and age on these analyses were also examined. The second purpose of this study was to elucidate the clinical picture of psychiatric disorders in this population. This was done by examining the rates of symptoms and disorders, the presence of subsyndromal diagnoses, and behavioral equivalents. Parents of 61 children and adolescents (mean age 11.22± 3.80; range 6-17) with autism, Asperger’s disorder, and PDD-NOS were interviewed with the P-ChIPS and Autism Diagnostic Interview-Revised (ADI-R) and completed the CASI and NCBRF.
The youngsters were administered the Stanford-Binet V IQ test. Interrater reliability kappa values were largely in the good to excellent range. Internal consistency values were good for ADHD, ODD, Social Phobia, Depression and Mania (.89-.86), but below acceptable values for Obsessions (.30) and Compulsions (.65). Concordance between the P-ChIPS and the CASI was fair (i.e., .41 < k < .57) for the majority of disorders. Percent overall agreement for most disorders was good with values at or above 70%, lending support to the concordant validity of the P-ChIPS. P-ChIPS derived diagnoses as a whole converged as expected with related NCBRF subscales. Subsyndromal analyses suggested that some modifications may be needed to diagnostic criteria cutoffs. Behavioral equivalent analyses were largely nonsignificant. The P-ChIPS appears to be appropriate for this population although some modifications may be necessary for those without language or IQ less than 70.
