Factorial Invariance of Scores on the Inner Wealth Inventory: A Nationwide Sample of Adults in the United States

The Inner Wealth Inventory (IWI) is a screening tool for measuring inner wealth (IW), a wellness-based construct centered on empowering clients to inherently value themselves for being who they are. The initial IWI score validation study was conducted with samples of child welfare professionals. If the IWI's psychometric properties are confirmed with a normative sample of U.S. adults, it has potential to offer professional counselors a tool for measuring IW. The purpose of the present study was to test the factorial invariance and convergent validity evidence of scores on the IWI with a national sample (N = 840) of U.S. adults, stratified by the census data for gender, ethnoracial identity, geographic location, and age. The results of factorial invariance and convergent validity testing revealed strong support for the psychometric properties of U.S. adults' scores on the unidimensional IWI, including equivalence in the meaning of IW across gender, ethnoracial identity, help-seeking history, education, and income in our sample.
