We explored the effects and interaction of fieldworker and respondent characteristics (age and gender) in substance (tobacco and alcohol) use reporting. We aim to further the literature on conditional social attribution effects on substance use reporting in the context of South Africa, where accurate estimates of modifiable risk factors are critical for medical and public health practitioners and policy-makers in efforts to reduce chronic disease burden and mortality.This project also received funding and administrative support from the University of Colorado Population Center, funded by the Eunice Shriver National Institute of Child Health and Human Development (NICHD R21 HD051146).application/pdfen-AU© 2018 International Journal of Alcohol and Drug Researchhttps://creativecommons.org/licenses/by-nc-nd/4.0/South Africaruralinterviewer effectssubstance userespondent reporting201810.7895/ijadr.2462020-11-23Creative Commons License Deed
