This scale measures how mindful and deliberate a consumer is about the things they choose to own. It is one of three dimensions in Wilson and Bellezza's (2022) multi-study development of a consumer minimalism instrument, alongside number of possessions and sparse aesthetics. The dimensions emerged from qualitative research and were then tested across several quantitative studies, with the higher-order construct of minimalism capturing a deliberate, curated approach to consumption.
7-point Likert (1=strongly disagree, 4=neither agree nor disagree, 7=strongly agree)

Alphas were .86 (Study 2) and .88 (Study 3) (Wilson and Bellezza 2022, p. 805); the scale was used in other studies without reported alphas. Test-retest correlations in Study 5 (p. 808) were .70 over one week (163 Columbia Business School graduate students) and .70 over seven weeks (245 Prolific participants). Evidence supported unidimensionality and content, discriminant, known-groups, and predictive validity; AVEs were .62 (Study 2) and .66 (Study 3). Directions: 'Please indicate your agreement with each of the following statements about yourself.'
