A Self-Perception Interpretation of the Effect of Monetary and Nonmonetary Incentives on Mail Survey Respondent Behavior
应用自我知觉理论解释邮件调查中激励对受访者行为的影响，发现外部激励（尤其是货币激励）会降低响应质量，但货币激励能显著提高响应率和速度。
Self-perception theory is applied to explain mail survey respondent behavior when incentives to respond are used. The results support the hypothesis that when external cues are present (i.e., incentives are used) the level of compliance, as measured by response quality, is reduced. A monetary and a comparable value nonmonetary incentive are used. The psychological value of money explanation is supported as the monetary incentive group yields a significantly higher response rate and faster response.
