Instruments and Analysis
An exploratory principal component factor analysis with Varimax rotation was performed on all the 50 items from the Ways of Coping Checklist. Only factors with an Eigenvalue of 2 or greater were considered, and only items that loaded 0.5 or greater on these factors were used. After the factor analysis was performed, two-tailed Pearson correlations were conducted using an α level of 0.5 or less as the statistical significance threshold. The coping factors found were each analyzed for correlations with each of the 10 domains of QoL from the correlations with each of the Wisconsin Quality of Life Index : life satisfaction, psychological well-being, physical QoL, social QoL, financial QoL, activities of daily living, general QoL, and mean QoL. The coping factors found were also each analyzed foe correlations with each of the four domains of symptom severity as per the Positive and Negative Syndrome Scale : positive symptoms, negative symptoms, general (comorbid) symptoms, and total symptoms (all symptom scores summed).
