Pathological and Nonpathological Worry: Their Relationships with Nightmare Frequency
William E. Kelly
Objective: Both worry and nightmares are relatively common phenomena and both are conceptually related. However, research investigating their relationship has not been reported. The aim of the current study was to investigate the statistical relationship between worry and nightmare frequency.

Methods: Using a cross-sectional design, university students (n=134) completed reliable and validated measures of nightmare frequency using the Schredl’s Nightmare Frequency Scale, trait pathological worry usimg the Three Item Worry Index (TIWI), nonpathological worry using the Worry Domains Questionnaire Short Form (WDQ-SF), and worry related sleep disturbance using the Sleep Disturbance Ascribed to Worry Scale (SAW).

Results: Higher frequency of nightmares was significantly correlated with higher scores on measures of pathological worry, nonpathological worry, and worry-related sleep disturbance. Using ordinal regression, it was determined that pathological worry, but not nonpathological worry or worry-related sleep disturbance, accounted for significant unique variance in nightmare frequency.

Conclusions: The results were consistent with conceptualizations of pathological worry and nightmare frequency as related to ego functioning and psychological distress. Individuals seeking psychotherapy reporting intense, uncontrollable worry might need to be evaluated for frequent nightmares as well. The results were discussed and suggestions for future research were offered.
