Self-reports of cigarette smoking in a sample of young adults, aged 17 to 21 (n = 359) obtained by telephone were validated by home interview and saliva cotinine measurement. While most subjects were in agreement for their reported behaviors, the telephone methodology underestimated cigarette smoking rates by 3 to 4 per cent. Reported quitting by telephone was an unstable category with 35 per cent of quitters reporting smoking on home interview. Reliance on telephone methods alone may underestimate smoking behavior. Validation of surveys, preferably by biochemical methods, is recommended.
通过电话对17至21岁的年轻成年人样本（n = 359）进行的吸烟情况自我报告，通过入户访谈和唾液可替宁测量进行了验证。虽然大多数受试者对其报告的行为一致，但电话调查方法低估了3%至4%的吸烟率。通过电话报告的戒烟情况不稳定，35%的戒烟者在入户访谈中报告仍在吸烟。仅依靠电话方法可能会低估吸烟行为。建议对调查进行验证，最好采用生化方法。
