当对精神病患者的样本进行两次状态和特质测量评估时，在尚未进行任何正式干预的情况下，通常会观察到评分的平均变化，即精神病理学程度降低。这种重测效应是对纵向研究有效性的一个潜在威胁，但使用重复给药的研究人员并未给予认真关注。本研究探讨了这个问题，在2个独立的临床样本的症状检查表-90修订版和其他广泛使用的状态和特质措施的重测效果。摄入和重新摄入之间的时间间隔为3个月和11-350天（M=93天，中位数=81天）。结果表明，重测效应对大多数的措施发生。在观察到显著测试效应的情况下，54-72%的患者的时间2评分低于平均时间1评分。的重要性和实际和科学的影响的研究结果进行了讨论。本文提出了关于重测效应的十一个假说，包括情绪一致性联想加工、自然应对机制、自我监控假说和反应转移假说。(C)2001爱思唯尔科技有限公司版权所有。
When samples of psychiatric patients are assessed on 2 occasions on state and trait measures, without any formal intervention having yet taken place, a mean change in scores towards less psychopathology is often observed. This re-test effect, which is a potential threat to the validity of longitudinal studies, has not been given serious attention by researchers using repeated administrations. The present study addressed this issue by examining re-test effects in 2 independent clinical samples with the Symptom Check List-90-Revised and other widely-used state and trait measures. Time intervals between intake and re-take were 3 months and 11-350 days (M=93 days, median=81 days). Results indicated that the re-test effect occurred for most of the measures. Where significant testing effects were observed, 54-72% of the patients had time 2 scores that were lower than the average time 1 scores. The importance and practical and scientific implications of the findings are discussed. Eleven hypotheses concerning the nature of the re-test effect are offered, including mood-congruent associative processing, natural coping mechanisms, self-monitoring hypothesis and response-shift.
