The purpose of this research was to present the latest development of the The Perceived Emotional Distress Inventory (PEDI) as a brief 15-item self-report measure intended to be used for the assessment of psychological distress in cancer patients. Factor Analyses of Principal Components with promax rotations were performed with a combined male and female sample of 481 cancer patients at St. Joseph’s hospital Cancer Institute in Tampa, Florida, to provide further evidence of construct validity. The factor structure, internal consistency, and Pearson correlation coefficients of the PEDI are presented in this report. The factor analysis identified three factors comparable to those found in previous samples in USA: The first factor, anxiety/depression; second factor, hopelessness; and third factor, anger expression. Global alpha coefficient of 0.92 for the inventory indicates strong internal consistency. Pearson correlations between the subscales of the instrument is impressive for such a brief measure. This study emphasizes the need for a brief, self-report instrument to assess anger expression, anxiety, depression and hopelessness as components of perceived emotional distress in cancer patients, while explicitly excluding the potentially confounding effects of somatic symptoms commonly associated with cancer treatments. Further research will be needed to provide information about the PEDI’s use in populations other than cancer patients including attempts to replicate these findings in more heterogeneous populations.
