CPP Cohort 4
The Generalized Anxiety Disorder 7 (GAD-7) is a self-report instrument that screens for generalized anxiety disorder by determining an adult’s level of anxiety symptoms. Higher scores indicate greater severity of anxiety.
Descriptive Statistics: Pre- and post-treatment assessment measure means, standard deviations, and standard errors for the GAD-7 are listed in the table below, as well as the range of possible scores.
Repeated Measures Analyses: Paired samples t-tests were conducted to examine pre-post group mean differences for the GAD-7 overall score. Analyses did not show statistically significant change for the GAD-7 overall score.
GAD-7: Paired Sample T-Test
GAD-7: Pre-Post Treatment Mean Scores
Individual Clinically Significant Change: Individual clinically significant change for the GAD-7 overall score was based on the suggested screening cut-point of 10. At pre-treatment, 13 clients had GAD-7 overall scores at or above the cut-point of 10. Of note, 10 of these 13 clients were missing the GAD-7 overall score at post-treatment. Analysis of the clients with post-treatment data showed that the GAD-7 overall score for 1 of the 3 clients (33%) decreased below the cut-point of 10.
