Item Metadata only Performance of the Tobacco, Alcohol, Prescription Medication, and Other Substance Use (TAPS) Tool for Substance Use Screening in Primary Care Patients.(Ann Intern Med, 2016-11-15) McNeely, Jennifer; Wu, Li-Tzy; Subramaniam, Geetha; Sharma, Gaurav; Cathers, Lauretta A; Svikis, Dace; Sleiter, Luke; Russell, Linnea; Nordeck, Courtney; Sharma, Anjalee; O'Grady, Kevin E; Bouk, Leah B; Cushing, Carol; King, Jacqueline; Wahle, Aimee; Schwartz, Robert PBackground: Substance use, a leading cause of illness and death, is underidentified in medical practice. Objective: The Tobacco, Alcohol, Prescription medication, and other Substance use (TAPS) tool was developed to address the need for a brief screening and assessment instrument that includes all commonly used substances and fits into clinical workflows. The goal of this study was to assess the performance of the TAPS tool in primary care patients. Design: Multisite study, conducted within the National Drug Abuse Treatment Clinical Trials Network, comparing the TAPS tool with a reference standard measure. (ClinicalTrials.gov: NCT02110693). Setting: 5 adult primary care clinics. Participants: 2000 adult patients consecutively recruited from clinic waiting areas. Measurements: Interviewer- and self-administered versions of the TAPS tool were compared with a reference standard, the modified World Mental Health Composite International Diagnostic Interview (CIDI), which measures problem use and substance use disorder (SUD). Results: Interviewer- and self-administered versions of the TAPS tool had similar diagnostic characteristics. For identifying problem use (at a cutoff of 1+), the TAPS tool had a sensitivity of 0.93 (95% CI, 0.90 to 0.95) and specificity of 0.87 (CI, 0.85 to 0.89) for tobacco and a sensitivity of 0.74 (CI, 0.70 to 0.78) and specificity of 0.79 (CI, 0.76 to 0.81) for alcohol. For problem use of illicit and prescription drugs, sensitivity ranged from 0.82 (CI, 0.76 to 0.87) for marijuana to 0.63 (CI, 0.47 to 0.78) for sedatives; specificity was 0.93 or higher. For identifying any SUD (at a cutoff of 2+), sensitivity was lower. Limitations: The low prevalence of some drug classes led to poor precision in some estimates. Research assistants were not blinded to participants' TAPS tool responses when they administered the CIDI. Conclusion: In a diverse population of adult primary care patients, the TAPS tool detected clinically relevant problem substance use. Although it also may detect tobacco, alcohol, and marijuana use disorders, further refinement is needed before it can be recommended broadly for SUD screening.

However, there are different ways of phrasing conceptually similar time frames (eg, past year vs. past 12 months).We conducted focused, abbreviated cognitive interviews with a sample of community health center patients (N = 50) to learn how they perceived and interpreted questions with alternative phrasing of similar time frames (past year vs. past 12 months; past month vs. past 30 days; past week vs. past 7 days).Most participants perceived the alternative time frames as identical. However, 28% suggested that the "past year" and "past 12 months" phrasings would elicit different responses by evoking distinct time periods and/or calling for different levels of recall precision. Different start and end dates for "past year" and "past 12 months" were reported by 20% of the sample. There were fewer discrepancies for shorter time frames.Use of "past 12 months" rather than "past year" as a time frame in self-report questions could yield more precise responses for a substantial minority of adult respondents.Subtle differences in wording of conceptually similar time frames can affect the interpretation of self-report questions and the precision of responses.Item Open Access VALIDATION OF THE 4-ITEM SCREENING COMPONENT OF THE TAPS TOOL TO IDENTIFY UNHEALTHY SUBSTANCE USE AMONG PRIMARY CARE PATIENTS(JOURNAL OF GENERAL INTERNAL MEDICINE, 2017-04-01) Schwartz, Robert; Gryczynski, Jan; McNeely, Jennifer; Wu, Litzy; Sharma, Gaurav; King, Jacquie; Jelstrom, Eve M; Nordeck, Courtney; Sharma, Anjalee; Mitchell, Shannon; O'Grady, Kevin; Svikis, Dace; Cathers, Lauretta; Subramaniam, Geetha
