Abstract

Prevalence findings for the elderly are artificially low, most likely due to insufficient consideration of age-related cognitive abilities in diagnostic interviews. Aims: (1) To describe the rationale for the development of an age-adapted Composite International Diagnostic Interview (CIDI65+) for use in a European project (MentDis_ICF65+). (2) To examine its test–retest reliability. Methods: Based on substantive pilot work the CIDI standard questions were shortened, broken down into shorter subsets and combined with sensitization questions and dimensional measures. Test–retest was determined in N= 68 subjects aged 60–79 years via two independent examinations by clinical interviewers using kappa (sensitivity, specificity) for categorical and intraclass correlation (ICC) coefficients for dimensional measures. Results: Test–retest reliability was good for any mental disorder (κ = 0.63), major depression (κ = 0.55), anxiety (κ = 0.62, range = 0.30–0.78), substance (κ = 0.77, range = 0.71–0.82), obsessive-compulsive disorder (κ = 1.00) and most core symptoms/syndromes (κ range =0.48–1.00). Agreement for some disorders (i.e. somatoform/pain) attenuated, partly due to time lapse effects. ICC for age of onset, recency, quantity, frequency and duration questions ranged between κ =0.60–0.90. Dimensional agreement measures were not consistently higher. Conclusion: The age-adapted CIDI65+ is reliable for assessing most mental disorders, distress, impairment and time-related information in the elderly, prompting the need to examine validity.
