Lack of disclosure of substance use is common in research and treatment settings and is frequently higher at follow-up than at baseline interviews. The aim of this study was to determine predictors of cocaine use disclosure at follow-up among 525 individuals who reported and tested positive for baseline use. Measurements included self-reported quantity and frequency of use, and hair analysis by radioimmune assay. Forty-two percent of individuals with biochemical evidence of continued cocaine use denied this use. In adjusted analyses, self-reported substance abuse treatment contact after enrollment was associated with lower disclosure (OR 0.63, 95% CI 0.43, 0.93). Other predictors were race, hair cocaine level, and opiates in hair. Failure to stop use after seeking treatment may result in reduced disclosure of continued use, possibly because of unwillingness to admit failure.
在研究和治疗环境中，隐瞒药物使用情况很常见，且随访时的隐瞒率通常高于基线访谈时。本研究的目的是确定在525名报告基线使用并检测呈阳性的个体中，随访时可卡因使用情况披露的预测因素。测量指标包括自我报告的使用量和频率，以及通过放射免疫分析法进行的毛发分析。有生化证据表明持续使用可卡因的个体中，42%否认了这种使用情况。在调整分析中，入组后自我报告的药物滥用治疗接触与较低的披露率相关（比值比0.63，95%置信区间0.43，0.93）。其他预测因素包括种族、毛发中的可卡因水平和毛发中的阿片类药物。寻求治疗后未能停止使用可能导致持续使用情况的披露减少，这可能是因为不愿意承认失败。
