Baseline differences in alcoholism problem severity were compared between alcoholics who did and did not volunteer to participate in a treatment effectiveness study. A positive relationship was found between self-reports of alcohol-related problems and the degree of research participation. Group differences were also revealed in the rate of treatment completion. Possible explanations and solutions for this volunteer bias are discussed.
对自愿参加和未自愿参加治疗效果研究的酗酒者的酒精中毒问题严重程度的基线差异进行了比较。研究发现，与酒精相关问题的自我报告和研究参与程度之间存在正相关关系。在治疗完成率方面也发现了组间差异。本文讨论了这种志愿者偏差的可能解释和解决方案。
