Serial neuropsychological assessments are complicated to interpret due to practice effects, regression to the mean, and “normal” change in clinical conditions. Nonetheless, they occur frequently in clinical practice and research. This webinar will compare and contrast the two most widely-used change score methods: Reliable Change Index + Practice Effects (RCI+PE) and Standardized Regression-Based (SRB) change scores. Using actual data in patients with Mild Cognitive Impairment, RCI+PE and SRB will be calculated and compared among subgroups of this sample. Factors that influence RCI+PE and SRB methods will be highlighted, as will methods for using these change scores in clinical practice and research. Although this webinar will be math-heavy, it should allow individuals to immediately start using these change methods in their clinical practice and research.

Learning Objectives:
1. Understand the conceptual differences between Reliable Change + Practice Effects (RCI+PE) and Standardized Regression Based (SRB) change scores.
2. Describe how to compute and apply basic mathematical formula for assessing cognitive change with RCI+PE and SRB in a sample of individuals with Mild Cognitive Impairment.
3. List the factors that influence the calculation of RCI+PE and SRB.
4. Apply a working knowledge of these change scores so that they can be applied in clinical settings and research projects.
