Assessment of Emotional Distress

 

DSC01041We are engaged in the assessment of emotional distress in cancer patients. In this regard, we have developed a psychometric measure to assess levels of emotional distress in our patients. This research was partially funded by the Susan G. Komen Foundation for breast cancer research and the Morton Plant Hospital Foundation and the studies were supported by the Cancer Committee of the Morton Plant Cancer Institute.

The Perceived Emotional Distress Inventory (PEDI) was first presented at the Pan American Congress of Psychosocial and Behavioral Oncology held in New York city in October 1999. Further reports and publications of the psychometric properties of the PEDI are listed at the bottom of this post.

 

BookThe Perceived Emotional Distress Inventory (PEDI)  is a 12-item self-report screening scale designed to reflect the presence and severity of emotional distress in cancer patients. The measure assesses anxiety, anger, depression, and Hopelessness, making distinctions regarding the expression and suppression of angry feelings. 

In responding to each PEDI item, subjects report to what extent they had experienced each emotional distress-related symptoms (“during the past month, including today”) by rating themselves on a 4-point scale.

A Global Severity Index (GSI) is determined simply by summing the ratings for each individual items that comprise the PEDI. The total score for the inventory range from 0 to 36 points. Higher scores correspond to higher levels of perceived emotional distress. The instrument has been developed for research purposes and our intention was to make comparisons between subjects in the study sample utilizing the raw scores and treating the statistical analyses as ordinal data.

As indicated in our references listed below, the alpha reliability coefficient for the entire instrument was .91, which adds significant internal consistency and credibility for a 12-item instrument. Considering that the measure is comprised of factors with small number of items, the internal consistency of this scale, as indicated by the global alpha coefficient and item-remainder correlations in our several studies, was surprisingly high. To download the PEDI and scoring information, click here: PEDI-R English
