Anti-consumption, seen as the opposite of materialism, is a growing field in consumer research, and one of its manifestations is voluntary simplicity. It is a lifestyle in which an individual limits his or her consumption in order to have more resources (time and money) to derive satisfaction from non-material goods. However, there are no scales in Polish that could be used to study it. The purpose of the present research was to fill this gap and conduct a Polish adaptation and validation of the voluntary simplicity scale. Two studies were conducted: the first, analysing the factor structure and reliability of the scale, and the second, examining its validity. The Polish version of the voluntary simplicity scale was found to be a valid and reliable tool in Polish conditions.
