Materialistic tendencies may originate in early childhood, and previous research shows that even preschoolers differ in the degree of their materialism. The goal of this project was to develop and validate a new instrument that reliably measures materialism in preschool children (4-6 years old). A simple and universal Pictorial Materialism Test (PMT) was created and its psychometric properties were evaluated. The PMT consists of 32 items reflecting two dimensions: acquisition as the pursuit of happiness and success defined by possessions. To evaluate the psychometric properties of the PMT, a total of 204 Polish children aged 4-6 years were recruited for the study using an opportunity sampling method. To examine the reliability of the PMT, we calculated the internal consistency, confirmatory factor analysis (CFA), and test-retest intra-class correlation. To determine the convergent validity of the PMT, correlations with another measure of materialism in children (Happiness Collage) and with age were examined. The results confirmed that materialism can be reliably reported by preschool children and that the PMT has satisfactory (albeit moderate) psychometric properties. The instrument developed in this project is promising for further research because it has the potential to be used in research on materialism in preschool children around the world. In conclusion, we propose a preliminarily validated new Pictorial Materialism Test to measure general materialistic tendencies and their dimensions (possession-driven happiness and materially defined success) in 4-6-year-old children.
唯物主义倾向可能起源于儿童早期,先前的研究表明,即使是学龄前儿童在唯物主义程度上也存在差异。本项目的目标是开发和验证一种新的工具,以可靠地衡量学龄前儿童(4-6 岁)的唯物主义倾向。创建了一个简单而通用的图片唯物主义测试(PMT),并评估了其心理测量特性。PMT 由 32 个项目组成,反映了两个维度:通过占有物来追求幸福和成功的获取。为了评估 PMT 的心理测量特性,我们使用机会抽样方法共招募了 204 名 4-6 岁的波兰儿童进行研究。为了检验 PMT 的可靠性,我们计算了内部一致性、验证性因素分析(CFA)和测试-重测内部一致性相关系数。为了确定 PMT 的聚合效度,我们考察了它与儿童另一种唯物主义测量工具(幸福拼贴画)和年龄的相关性。结果证实,学龄前儿童可以可靠地报告唯物主义倾向,并且 PMT 具有令人满意的(尽管是中等的)心理测量特性。本项目中开发的工具具有很大的研究潜力,因为它有可能被用于研究世界各地学龄前儿童的唯物主义倾向。总之,我们提出了一个初步验证的新图片唯物主义测试,以衡量 4-6 岁儿童的一般唯物主义倾向及其维度(以占有物为导向的幸福和物质定义的成功)。
