VALIDATION OF THE DEROGATIS STRESS PROFILE USING LABORATORY AND REAL WORLD DATA

The Derogatis Stress Profile (DSP) is unique among the numerous measures of 'stress' in that it incorporates the interactional model of Lazarus and Folkman in a multi-dimensional structure. Derogatis has studied the psychometric properties of the DSP but its validity has not been demonstrated in the 'real world' nor has it been related to psychophysiological data. The present investigation was aimed at testing the validity of the DSP in these two areas. Forty-three men between the ages of 18 and 30 years completed the DSP, the Daily Hassles Scale (DHS), the Life Experiences Survey (LES), the Profile of Mood States (bipolar form), and the Jackson Personality Inventory (JPI). Participants were exposed to stressors in a laboratory setting as well as in the field while their heart rate was being monitored. Results supported the validity of the DSP, in part. The correlation between the DSP and JPI anxiety scores was significant as was the correlation between the DSP and the daily depression scores. The correlation between the Total Stress Score (TSS) of the DSP and DHS was significant as were the correlations between the TSS and LES scores. Moreover, the DSP scores were related to heart rate reactivity both in the laboratory and in the field.
