Product care is defined as all activities initiated by consumers that encourage an extension of product lifetimes, such as repair, maintenance, and/or careful handling. A product care scale was developed and validated in a set of four related studies. In study 1, we asked experts to examine the face validity of a set of 35 items. In study 2, we reduced the initial set of items to 10 items using exploratory factor analysis. A subsequent confirmatory factor analysis supported a three-factor solution. Study 3, a nomological network study, demonstrated that the construct measured by our scale is related but still distinguishable from existing concepts, such as frugality, use innovativeness and attachment towards the product. Study 4 was a known-groups test with participants from two different countries and with various previous experiences in repairing. The final 10-item product care scale includes three factors: relevance, easiness and positive experience.

产品保养定义为由消费者发起的鼓励延长产品寿命的所有活动，例如维修，保养和/或小心处理。在四项相关研究中开发并验证了产品护理量表。在研究1中，我们请专家检查一组35个项目的面部有效性。在研究2中，我们使用探索性因素分析将初始项目集减少为10个项目。随后的验证性因素分析支持了三因素解决方案。研究3（一项法理网络研究）表明，以我们的规模衡量的结构是相关的，但仍与现有概念（例如节俭，使用创新和对产品的依恋）有所区别。研究4是由两个不同国家的参与者组成的已知人群测试，并且具有各种以前的维修经验。最终的10个项目的产品护理量表包括三个因素：相关性，易用性和积极经验。
