The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information-Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15-item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross-validation of the results. A two-factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information-Processing Questionnaire. The availability of this information-processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.
信息处理在理解人们对风险信息的反应方面的作用最近受到了广泛关注。这项研究的一个局限性在于缺乏经过验证的信息处理问卷。本文介绍了两项研究，旨在满足这一需求，描述了信息处理问卷的开发和验证。研究 1 描述了问卷的开发和初步验证。参与者在完成操纵检查和初始 15 项问卷后，随机分配到系统处理或启发式处理条件，两周后再次完成。为了对结果进行交叉验证，该问卷在两次测量时都进行了因子可靠性和有效性分析。观察到一个包含系统处理和启发式处理分量表的两因素解决方案。得到的量表具有良好的可靠性和有效性，系统条件在系统分量表上的得分显著更高，启发式处理条件在启发式分量表上的得分显著更高。研究 2 旨在在实地研究中进一步验证问卷。第二项研究的结果与研究 1 一致，为信息处理问卷的有效性提供了进一步的证据。该信息处理量表的可用性将是未来研究的宝贵资产，并可能为研究人员提供新的研究机会。
