Abstract: Sufficiency is a strategy that aims at a collectively reduced consumption of goods and services with the aim to respect the ecological boundaries. The realization of the strategy lies within the individual sphere albeit structural and and other contextual factors are important to facilitate sufficiency. Thus, a psychological approach was chosen to investigate the properties of a sufficiency lifestyle in everyday behavior and consumption on the individual level. A questionnaire concerning a broad range of sufficiency-related behaviors and attitudes was developed and applied via an online survey tool (sample size N = 177). The results showed a good reliability of the behavior scale, meaning that the behaviors are related to the same construct. This indicates that sufficiency is observable in the individual behavior. For a more detailed understanding of sufficiency a factor analysis revealed five different dimensions within sufficiency behavior. These dimensions will be presented and discussed.
