Objectives:
The Lichtenberg Financial Decision Rating Scale (LFDRS) is a person-centered tool for analyzing the integrity of financial decision-making abilities. Initial studies supported its reliability and validity (Lichtenberg et al., 2020; Lichtenberg et al., 2017; Lichtenberg et al., 2015). This study examines the cross-validation of the LFDRS Scale to assess its concurrent validity with a measure of executive functioning and suspected financial exploitation (FE).
Methods:
Ninety-five older adult community participants underwent an assessment session. The total LFDRS was significantly related to executive functioning.
Results:
Trail Making Test Part B was the only significant predictor of the LFDRS total score in a regression equation. An independent sample t-test showed that victims of FE scored higher on the LFDRS than those who were not victims.
Conclusions:
These findings are consistent with the initial validation study of the LFDRS and the initial study on the intersection of decision-making and FE (Lichtenberg et al., 2017, 2020) and adds evidence supporting the LFDRS concurrent validity.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
