Key findings Nightmare distress correlated with several factors besides nightmare frequency: neuroticism, female sex, low education, extraversion, low agreeableness, sensation seeking, and a higher percentage of replicative trauma-related nightmares. Harm avoidance was not helpful in explaining individual differences in nightmare distress. The authors argue these associations are clinically important but note that relationships with education and agreeableness are not yet understood.

Abstract

Study

Objectives: The diagnosis of a nightmare disorder is based on clinically significant distress caused by the nightmares, eg, sleep or mood disturbances during the day. The question what factors might be associated with nightmare distress in addition to nightmares frequency is not well studied.

Methods: Overall, 1,474 persons (893 women, 581 men) completed an online survey. Nightmare distress was measured with the Nightmare Distress Questionnaire.

Results: The findings indicated that nightmare distress, measured by the Nightmare Distress Questionnaire, correlated with a variety of factors in addition to nightmare frequency: neuroticism, female sex, low education, extraversion, low agreeableness, and sensation seeking. Moreover, the percentage of replicative trauma-related nightmares was also associated with higher nightmare distress.

Conclusions: A large variety of factors are associated with nightmare distress, a finding that is of clinical importance. The construct harm avoidance, however, was not helpful in explaining interindividual differences in nightmare distress. Furthermore, the relationship between nightmare distress and other factors, eg, education or agreeableness, is not yet understood.
