Center for Alcohol & Drug Studies & Services

Welcome to the Center for Alcohol and Drug Studies

The Center for Alcohol and Drug Studies is a project of San Diego State University School of Social Work. Originally named the Center on Substance Abuse, the Center was established in 1987 by Dr. Anita S. Harbert to address alcohol and other drug related problems at San Diego State University and in the larger community.

The Center specializes in research and evaluation design with an emphasis on socio-behavioral research and applied evaluation. Our multi-disciplined staff have decades of experience in research and evaluation and are highly committed to scientific excellence.

The Center serves as an umbrella organization for several alcohol and drug related research initiatives, including the California Screening Brief Intervention, Referral and Treatment Services.

We invite you to learn about us through our website.

Predictors of Error in Estimates of Blood Alcohol Concentration: A Replication

Objective: To identify predictors of error in estimated blood alcohol concentration (eBAC) in a sample of bar patrons. Method: Six hundred sixty-six patrons (43.6% female) were randomly sampled from 32 bars. Patrons were asked to provide a breath sample into a handheld breath alcohol concentration test unit upon entrance and exit. For analyses, this sample was stratified by whether patrons consumed alcohol before attending the bar. Estimates of BAC were calculated using Matthews and Miller's formula (1979). A three-category dependent variable was created based on the estimation accuracy of eBAC relative to breath alcohol concentration: accurate (within .02), underestimate of BAC, and overestimate of BAC.
