Perceived Emotional Distress Research

 The Perceived Emotional Distress Inventory (PEDI)  (Moscoso, et al., 1999, 2000; Moscoso & Reheiser, 2010; Moscoso, Lengacher & Reheiser, 2012) is a 15-item self-report screening scale designed to reflect the presence and severity of emotional distress and general mood disturbance. 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 ranging from 0 to 3: not at all (0); sometimes (1); often (2); very much so (3).

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 45 points. Higher scores correspond to higher levels of perceived emotional distress. The PEDI is not a diagnostic measure, therefore there are no cut-offs scores. Since the instrument has been developed for research purposes only, our intention was to make comparisons between subjects in the study sample.

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 15-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.
