Using the 2001–2004 Medical Expenditures Panel Survey, we examined rates of past-year adolescent time alone with a clinician by visit type, and among youths with a preventive visit, examined age, gender, and race/ethnicity differences. Youths with a preventive visit have higher rates of time alone; rates for these youths increase with age, are higher for males (42%) versus females (37%), and are lowest among Hispanics. Time alone rates are low, especially for younger females and Hispanic youths. Special efforts are needed to increase time alone in these populations.
