| Abstract: |
Background: This report describes the preliminary psychometric evaluation of the Diagnostic Interview for Adolescents and Adults with Intellectual Disability--An interview schedule of mental disorders (DIAAID), an accessible structured interview for individuals with intellectual disability. Method: We examined test-retest reliability, inter-rater reliability, and concordance between direct and other-informant reports. Results: Intraclass correlations (CCs) for test-retest ranged from good to poor (ICC 0.79-< 0.50). ICCs for inter-rater reliability revealed excellent to moderate reliability between two independent raters (ICC 1.00-0.65). Percent agreement was high for positive and negative diagnoses between adolescent/adult participants (AAPs) and study partner participants (SPPs) (87.7%-100%) and between two raters of the same direct-report interview (90.9-100). Although SPPs endorsed more symptoms than AAPs, AAPs endorsed some that SPPs did not, with poor agreement between direct and informant reports (ICC -0.01 to 0.30). Conclusion: Preliminary psychometric findings are promising though not compelling. The direct report detects symptoms not noted by the caregiver. |
