Consumer researchers have long been interested in understanding the development of materialistic attitudes and values in different cultural settings. The life course approach, which has developed recently as an interdisciplinary programme for studying various aspects of behaviour, was used as an overarching framework for studying the development of materialism in Thailand. Specifically, the paper first presents the general conceptual framework that serves as a blueprint for discussing theoretical perspectives. Next, hypotheses derived from life course perspectives are formulated, and a survey of young adults (ages 20 to 32) is used to test them. We found that family disruption influences materialism only among those young adults from lower social classes. Findings of this paper have implications for theory development and suggest directions for future research.
