Study V: Children's Interview for Psychiatric Syndromes (ChIPS): psychometrics in two community samples

Abstract

Objective: To determine sensitivity and specificity of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) revised Children's Interview for Psychiatric Syndromes (ChIPS) in nonclinical samples.

Method: Participants were 40 children 6 to 18 years of age from a community sample (n = 22) or a bereaved sample 1 to 2 years following the death of a parent (n = 18). ChIPS and the Diagnostic Interview for Children and Adolescents (DICA-R-C) were administered in a Latin Square design. A consensus conference (CC) of child psychopathology experts determined presence or absence of syndromes or symptoms after reviewing assessment materials not including ChIPS.

Results: Sensitivity is commensurate with epidemiologic base rates (17.5% of participants endorsed at least one syndrome). Low base rate kappas and percentage agreement were calculated to determine agreement on symptom or syndrome endorsement for 20 disorders. For syndrome analyses, over half the kappas could not be calculated due to 100% agreement on absence. For symptom analyses, 3 of 20 kappas could not be calculated (100% agreement on absence). Eleven of ChIPS/DICA-R-C symptom kappas were significant (p < 0.04), 2 of 17 had 95% agreement (kappas, p < 0.08), and 4 of 17 had 97.5% agreement (kappas, p < 0.16). Thirteen of 17 ChIPS/CC symptom kappas were significant (p < 0.04), and 4 of 17 had 97.5% agreement (kappas, p < 0.16).

Conclusion: ChIPS' psychometrics in nonclinical samples compares favorably with that of other structured interviews.
