The I COPPE Scale Short Form for measuring multidimensional well‐being: Construct validity and reliability from US, Argentinian, and Italian large samples

The aim of this study is to present a short form of the I COPPE scale of multidimensional well‐being. We conducted two studies, which include four samples collected across three countries, namely United States, Argentina, and Italy. In the pilot study we tested during the data analysis phase whether it was feasible to reduce the full I COPPE scale by omitting the items dealing with past well‐being. Prompted by the positive results of the pilot study, we launched a final validation study with a sample of 2682 Italian people who completed the I COPPE scale short form, which is designed without items referring to past well‐being. Results from a series of confirmatory factor analyses show that the I COPPE scale short form presents acceptable levels of construct validity and reliability. Moreover, the 7‐factor correlated‐trait model proved to be the best fit for the data. We discuss advantaged of using the I COPPE scale short form along with limitations and future recommendations.
