Packed and claimed for sustainability: A multi-experiment test of how consumers perceive packaging sustainability

We conducted three experimental studies to analyze the impact of packaging materials and sustainability claims on sustainability perceptions, product expectations (e.g., regarding healthiness, tastiness, price), willingness-to-consume and product choices.

Study 1 is split up into two parts. Study 1a zooms in on the difference between glass and plastic, while Study 1b zooms in on the difference between carton and metal. The data are included in one dataset. The study had a 2 (packaging material: seemingly sustainable vs seemingly unsustainable) x 2 (sustainability claim: present vs absent) x 2 (packaging color: green vs red) x 4 (cue-product combination sets) between-subjects design. We conducted ANOVAs and chi square tests to analyze our results.

Study 2 zooms in on the difference between glass and plastic. The experiment has a 2 (packaging material: glass vs plastic) x 2 (sustainability claim: present vs absent) x 4 (cue-product combination sets) mixed design. We conducted multilevel analyses to analyze our results. The dataset was restructured to conduct these multilevel analyses. We used the syntax to obtain the parameter estimates. The syntax is included along with the datasets. We also conducted chi square tests.

本研究开展三项实验性研究，以分析包装材料与可持续性声明对消费者可持续认知、产品预期（如健康性、口感、价格感知）、消费意愿与产品选择的影响。
研究1分为两个子部分：子研究1a聚焦于玻璃与塑料包装的差异，子研究1b聚焦于纸盒与金属包装的差异，所有数据均收录于同一数据集。该研究采用2（包装材料：看似可持续vs看似不可持续）×2（可持续性声明：存在vs缺失）×2（包装颜色：绿色vs红色）×4（提示-产品组合集）的被试间实验设计，本研究通过方差分析（ANOVA）与卡方检验（chi-square test）对结果进行分析。
研究2聚焦于玻璃与塑料包装的差异，实验采用2（包装材料：玻璃vs塑料）×2（可持续性声明：存在vs缺失）×4（提示-产品组合集）的混合实验设计。本研究通过多层级分析对结果进行解析，为适配多层级分析需求对数据集进行了重构，并通过语法脚本获取参数估计值，语法脚本与数据集一同提供。本研究同时开展了卡方检验（chi-square test）。
