Previous research found that nightmare proneness, a purported disposition to experience frequent nightmares, accounted for nightmare frequency independent of neuroticism and distress. However, these findings may have been the result of reduced reliability and content validity of the measures. The current study aimed to replicate these findings using established, lengthier measures of neuroticism and distress. In the present cross-sectional study, 230 university students completed measures of nightmare frequency, nightmare proneness, neuroticism, and distress. Regression models found that nightmare proneness incrementally predicted nightmare frequency above neuroticism and distress. Additional analyses indicated that neuroticism and distress indirectly predicted nightmare frequency through nightmare proneness, whereas nightmare proneness was not associated with nightmares through neuroticism or distress. Nightmare proneness was statistically separable from neuroticism and distress. The results and suggestions for future research to better understand the nightmare proneness variable are discussed.
先前的研究发现，噩梦倾向（一种据称会频繁经历噩梦的倾向）能独立于神经质和痛苦程度来解释噩梦频率。然而，这些发现可能是由于测量方法的可靠性和内容效度降低所致。当前的研究旨在使用既定的、更长的神经质和痛苦程度测量方法来重复这些发现。
在本横断面研究中，230名大学生完成了噩梦频率、噩梦倾向、神经质和痛苦程度的测量。
回归模型发现，噩梦倾向在神经质和痛苦程度之上逐步预测噩梦频率。进一步分析表明，神经质和痛苦程度通过噩梦倾向间接预测噩梦频率，而噩梦倾向并非通过神经质或痛苦程度与噩梦相关。噩梦倾向在统计学上可与神经质和痛苦程度区分开来。本文讨论了研究结果以及为更好理解噩梦倾向变量而进行未来研究的建议。
