Consumers play an important role as one of the main actors in food safety social co-governance. To create a pattern of food safety social co-governance, the active and effective participation of consumers is critical. To encourage consumers to participate in food safety social co-governance voluntarily and positively, we attempted to develop and preliminarily validate a multidimensional questionnaire on consumer psychological capital that could be used to measure the degree of consumer participation in food safety social co-governance. The aim of the initial sample ( = 170) and test sample 2 ( = 204) was to investigate the factor structure of a preliminary measure of consumer psychological capital. A 4-factor model with 23 items explained 61.05% of the total variance in item scores. The aim of test sample 3 ( = 30) was to measure the retest reliability. Test sample 4 ( = 1,076) was randomly allocated to the modeling sample ( = 538) and validation sample ( = 538) to verify questionnaire reliability and validity. Convergent validity, discriminant validity, and the internal inconsistency coefficients of the questionnaire were assessed in the modeling sample. While processing CFA, we deleted 9 items with small standardized factor loadings. The remaining 14 items in the final revised 4-factor model included self-efficacy, resilience, hope, and optimism. The fit indices of the revised four-factor model and second-order factor model in the modeling sample revealed an acceptable model fit. The convergent validity and discriminant validity of the revised model were good and acceptable, respectively. A cross-validation procedure confirmed the appropriateness of the revised four-factor model and second-order factor model in the validation sample. The cross-validation results confirmed that the fit indices of the revised four-factor model fitted the data well and the second-order factor model in the validation sample reached acceptable values. We concluded that the questionnaire developed in this study had good reliability and stable and acceptable construct validity. It could provide a theoretical basis for measuring psychological capital in food safety co-governance.
消费者作为食品安全社会共治的主要行为主体之一，发挥着重要作用。要构建食品安全社会共治格局，消费者的积极有效参与至关重要。为鼓励消费者自愿且积极地参与食品安全社会共治，我们尝试编制并初步验证一份关于消费者心理资本的多维问卷，该问卷可用于衡量消费者参与食品安全社会共治的程度。初始样本（n = 170）和测试样本2（n = 204）的目的是探究消费者心理资本初步测量指标的因子结构。一个包含23个条目的四因子模型解释了条目得分总方差的61.05%。测试样本3（n = 30）的目的是测量重测信度。测试样本4（n = 1076）被随机分配到建模样本（n = 538）和验证样本（n = 538）中，以验证问卷的信效度。在建模样本中评估了问卷的收敛效度、区分效度和内部一致性系数。在进行验证性因素分析时，我们删除了9个标准化因子载荷较小的条目。最终修订的四因子模型中的其余14个条目包括自我效能感、心理韧性、希望和乐观主义。建模样本中修订后的四因子模型和二阶因子模型的拟合指数显示模型拟合度可接受。修订模型的收敛效度和区分效度分别良好且可接受。交叉验证程序证实了修订后的四因子模型和二阶因子模型在验证样本中的适用性。交叉验证结果证实，修订后的四因子模型的拟合指数与数据拟合良好，验证样本中的二阶因子模型达到了可接受的值。我们得出结论，本研究编制的问卷具有良好的信度以及稳定且可接受的结构效度。它可为食品安全共治中测量心理资本提供理论依据。
