目的：自我报告仍然是评估酒精消费的最常见的手段，尽管其有效性的关注。本研究的目的是评估社会期望偏差在多大程度上与自我报告的消费，危险使用和harms.Methods：在两项研究中，大学生（N = 391和N = 177）报告他们在过去一年中饮酒的人完成了在线保密调查。这两项研究都表明，印象管理偏见和自我报告的消费之间存在一致的关联，例如，高印象管理者报告的消费减少了20%至33%，报告危险饮酒的可能性减少了约50%。没有显着的相关性，涉及消费被发现自欺偏见。研究2还表明，高印象经理报告减少30-50%的急性伤害后，饮酒事件，这些影响保持统计控制后的特质冲动/constrain.Conclusions：印象管理偏见的有效性自我报告的酒精使用和危害的显着威胁。这种偏见可能导致模型的错误说明和对有害或危险用途的低估。(C)2009爱思唯尔有限公司保留所有权利。
Aims: Self-reports remain the most common means of assessing alcohol consumption despite concern for their validity. The objective of this research is to assess the extent to which social desirability biases relate to self-reported consumption, hazardous use, and harms.Methods: In each of two studies presented, undergraduate students (N = 391 and N = 177) who reported that they had consumed alcohol in the past year completed online confidential surveys.Results: Both studies show consistent associations between impression management bias and self-reported consumption such that high impression managers report 20 to 33% less consumption and are about 50% less likely to report risky drinking. No significant correlations involving consumption were found for self-deception bias. Study 2 also indicated that high impression managers report 30-50% fewer acute harms following a drinking episode, and that these effects are maintained after controlling statistically for trait impulsivity/constraint.Conclusions: Impression management bias represents a significant threat to the validity of self-reported alcohol use and harms. Such bias may lead to misspecification of models and under-estimates of harmful or hazardous use. (C) 2009 Elsevier Ltd. All rights reserved.
