This research examined the impact of completing a questionnaire about blood donation on subsequent donation behavior among a large sample of experienced blood donors.
Participants (N=4672) were randomly assigned to an experimental condition that received a postal questionnaire measuring cognitions about donation or a control condition that did not receive a questionnaire.
Number of registrations at blood drives and number of successful blood donations were assessed using objective records both 6 months and 12 months later.
Findings indicated that, compared to control participants, the mean frequency of number of registrations at blood drives among participants in the experimental group was 8.6% greater at 6 months (p<.0.007), and was 6.4% greater at 12 months (p<.035). Significant effects were also observed for successful blood donations at 6 months (p<.001) and 12 months (p<.004).
These findings provide the first evidence that the mere measurement is relevant to promoting consequential health behaviors. Implications of the research for intervention evaluation are discussed.
本研究考察了在大量有献血经验的献血者样本中，填写一份关于献血的问卷对后续献血行为的影响。
参与者（N = 4672）被随机分配到一个实验条件组，该组收到一份测量对献血认知的邮政问卷，或一个未收到问卷的对照组。
在6个月和12个月后，使用客观记录评估献血活动的登记人数和成功献血次数。
研究结果表明，与对照组参与者相比，实验组参与者在献血活动中的登记次数平均频率在6个月时高出8.6%（p <.007），在12个月时高出6.4%（p <.035）。在6个月（p <.001）和12个月（p <.004）时，成功献血次数也观察到显著影响。
这些发现首次证明仅仅进行测量就与促进相应的健康行为相关。讨论了该研究对干预评估的意义。
