Attitudes toward Homelessness Inventory: A psychometric analysis

The Attitudes toward Homelessness Inventory (ATHI) was developed due to a lack of psychometrically sound instruments to measure the nature and change in attitudes toward homelessness. Given inconsistencies in its use and internal reliability, this study evaluates the psychometric properties of the ATHI. Participants (n = 899) were selected using a random-digit-dial telephone survey to complete the ATHI. Results demonstrated that the four-factor solution suggested by the ATHI developers was the best fit for the data, but factor loadings and reliability coefficients were not sufficient for ensuring adequate measurement of attitudes toward homelessness. The poor psychometrics found in this study were likely the result of now outdated items. While the ATHI was developed using well-regarded and rigorous methods, results from this study suggest that it may be necessary to either make edits to the ATHI or to develop a new conceptually and psychometrically-sound measure.
