The Brief Child and Family Phone Interview (BCFPI): 2. Usefulness in screening for child and adolescent psychopatholog

This study examines the use of the Brief Child and Family Phone Interview (BCFPI) to screen for childhood psychiatric disorder based on Diagnostic Interview Schedule for Children Version IV (DISC-IV) classifications of attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), conduct disorder (CD), separation anxiety (SAD), generalized anxiety (GAD) and major depression (MDD). Data for analysis come from a sample of 399 children and adolescents aged 5-17 years old referred to child mental health outpatient services in three Ontario cities. Mothers were administered the BCFPI on three occasions: baseline, 2 and 13 months; and the DISC-IV on two occasions: 1 and 12 months. Based on kappa, test-retest reliability for disorders classified by the BCFPI exceeded .50 for all conditions except MDD (.45). In receiver operating characteristic (ROC) analysis, area-under-the-curve (AUC) estimates for BCFPI scale score associations with DISC-IV classifications of disorder exceeded .80 for CD, ODD, ADHD and SAD; and were lower for GAD (.76) and MDD (.75). In stratified analyses, there were no statistically significant differences in AUC estimates for boys versus girls and 5 to 11 versus 12 to 17-year-olds. Classifications of childhood disorder derived from the BCFPI provided a reasonable approximation to disorders classified by the DISC-IV administered by lay interviewers.
