Fit indices for investigated models.

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.
