ABSTRACT
In this chapter, the authors present several examples of published research that used the within-subjects analysis of variance (ANOVA). In this first case study, the researchers report on their work around mindfulness training for college students. Specifically, they were interested in testing whether psychological outcomes would improve after a mindfulness-based stress reduction program. Researchers followed students across a pre-test, a post-test after eight weeks of the program, and a follow-up eight weeks after the post-test. The authors measure global severity index as an indicator of psychological distress. This score came from the Brief Symptom Inventory, which is an 18-item scale that yields several subscale scores, including the global severity index. In the second case study, the authors interest in how peer mentoring could improve academic performance in introductory psychology courses. They measured students who were in introductory courses across four exams, using the exam scores as dependent variables.
