There has been a lack of consensus among researchers and practitioners about how to define financial literacy, but there is agreement that financial education changes depending on the stage of life to which people belong. This study provides consensus on what topics are considered a part of financial literacy specifically for traditional aged undergraduate college students. Many students take on debt to finance their college education and college is the time that people are laying the foundation for their financial future. The rising costs of a college education, combined with low levels of financial literacy amongst this population, indicates the need for financial education at the college/university level. In the past, there has been no definition of exactly what college students need to learn during this stage of life regarding financial planning. This lack of definition has also made it hard to measure financial literacy of college students. This study addresses both of these concerns. Utilizing the Delphi method, experts generated a list of financial planning topics that should be included in financial literacy for all traditionally aged undergraduate students. Those results were then used to create an instrument that measures financial literacy, which includes financial knowledge, financial attitude, and financial behavior. The instrument was refined utilizing multiple methods including item-score correlation, the items' contribution to Cronbach's a, the Q3 statistic, exploratory factor analysis, confirmatory factor analysis, and item response theory. Through the refinement process, a final instrument was created with 4 subscales: a 26-item scale measuring financial knowledge, a 5-item scale measuring financial planning attitude, a 5-item scale measuring financial management attitude, and a 15-item scale measuring financial behavior. These findings are relevant for both researchers and financial planning practitioners. [The dissertation citations contained here are published with the permission of ProQuest LLC.
