OBJECTIVE: This analysis evaluated the validation results of the Tobacco, Alcohol, Prescription Medication, and Other Substance Use (TAPS) tool for older adults.
METHODS: We performed a subgroup analysis of older adults aged =65 (n = 184) from the TAPS tool validation study conducted in 5 primary care clinics. We compared the interviewer and self-administered versions of the TAPS tool at a cutoff of =1 for identifying problem use with a reference standard measure, the modified World Mental Health Composite International Diagnostic Interview.
RESULTS: The mean age was 70.6 ± 5.9 years, 52.7% were female, and 49.5% were non-Hispanic Black. For identifying problem use, the self-administered TAPS tool had sensitivity of 0.91 (95% CI: 0.75–0.98) and specificity of 0.91 (95% CI: 0.85–0.95) for tobacco; sensitivity of 0.68 (95% CI: 0.45–0.86) and specificity of 0.88 (95% CI: 0.82–0.93) for alcohol; and sensitivity 0.86 (95% CI: 0.42–1.00) and specificity 0.94 (95% CI: 0.90–0.97) for cannabis. The interviewer-administered TAPS tool had similar results. We were unable to evaluate its performance for identifying problem use of individual classes of drugs other than cannabis in this population due to small sample sizes.
CONCLUSIONS: While the TAPS had excellent sensitivity and specificity for identifying tobacco use among older adults, the results for other substances lack precision, and we were unable to evaluate its performance for prescription medications and individual illicit drugs in this sample. This analysis underlines the critical need to adapt and validate screening tools for unhealthy substance use, specifically for older populations who have unique risks.
