Four items assess how confident and capable a person feels when making decisions within a specific domain, as well as the perceived ease of those decisions. Park and Sela (2018) used the scale primarily in the context of financial investment decisions. A two-item version (items 1 and 4 only) was used in a study in the web appendix.
