Part 3: Cumulative Homework
1. The effects of a new faith-based anxiety treatment program are studied in a group of elderly patients with Generalized Anxiety Disorder (GAD). One of the outcome measures is the Geriatric Anxiety Inventory (GAI) (Pachana et al., 2007), a measure with possible scores from 0–20, with higher scores indicating higher anxiety. A large group of elderly patients completed the GAI before treatment. Fifteen patients with GAI scores of 10 or higher were chosen to participate in the study. The patients underwent the treatment program and completed the GAI at the end of treatment. The scores are listed below. Do the elderly patients exhibit lessened anxiety, as demonstrated by their GAI scores, after participating in the faith-based treatment program? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below.
