Abstract
Few studies have considered the completeness and accuracy of smoking histories from surrogates for deceased workers. We surveyed 68 surrogates for uranium plant workers who completed smoking histories before their deaths. Completeness: 96% of surrogates answered definitively (yes or no) about overall smoking status (e.g., used any tobacco type), and 79 to 100% of those answered definitively about specific tobacco types. Of those reporting positive history, 50% to 67% answered detailed questions. Accuracy: Surrogates were accurate about overall smoking status (Kappa (kappa) = 0.75) compared with index self-report, but tended to underreport (P = 0.10). Spouses and nonspouses performed similarly. Accuracy by tobacco type was moderate (kappa = 0.21 to 0.56), with cigar smoking underreported. Surrogates for cigarette smokers underreported duration and amount smoked. Surrogates for deceased workers can report accurately on overall smoking status, but underreport other smoking habits.
