STUDY OBJECTIVES The present research examines the relationship between people's frequent involvement in an activity they like and find important (i.e., a passion) and the quality of their sleep. Research on the dualistic model of passion1-2 has widely documented the relationship between individual's type of passion-harmonious vs. obsessive-and the quality of their mental and physical health3-5. However, research has yet to examine the relationship between passion and sleep quality. Building on prior research that has shown that obsessive (vs. harmonious) passion is related to depressive mood symptoms6-7-an important factor associated with sleep problems- we hypothesized that obsessive passion would be associated with overall worse sleep quality, whereas harmonious passion would predict better sleep quality. METHODS A sample of 1,506 Americans filled out an online questionnaire on sleep habits and passion. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Hierarchical linear regressions and mediation analyses were carried out with results confirming our hypotheses. RESULTS Obsessive passion for an activity was linked to worse, whereas harmonious passion was linked to better sleep quality, adjusting for demographics, the type of passionate activity and its subjective importance, alcohol and tobacco consumption, BMI, subjective health, and diagnosed health conditions. The relationship between both types of passion and sleep quality was mediated by depressive mood symptoms. CONCLUSIONS Our study presents evidence of a strong relationship between sleep quality and passion, opening the door for future research to create new interventions to improve people's sleep and, consequently, their well-being.

对活动的热情：睡眠质量的新预测指标

研究目标 本研究调查了人们经常参与他们喜欢并认为重要的活动（即激情）与他们的睡眠质量之间的关系。对激情二元模型的研究 1-2 广泛记录了个人的激情类型——和谐与强迫——与其身心健康质量之间的关系 3-5。然而，研究尚未检验激情与睡眠质量之间的关系。基于先前的研究表明，强迫（与和谐）激情与抑郁情绪症状有关 6-7——与睡眠问题相关的一个重要因素——我们假设强迫激情与整体较差的睡眠质量有关，而和谐激情会预测更好的睡眠质量。方法 样本 1，506 名美国人填写了一份关于睡眠习惯和热情的在线问卷。使用匹兹堡睡眠质量指数 (PSQI) 测量睡眠质量。进行了分层线性回归和中介分析，结果证实了我们的假设。结果 对某项活动的痴迷与更糟有关，而和谐的热情与更好的睡眠质量有关，根据人口统计、热情活动的类型及其主观重要性、酒精和烟草消费、BMI、主观健康和诊断的健康状况进行调整。两种类型的激情和睡眠质量之间的关系是由抑郁情绪症状介导的。结论 我们的研究提供了睡眠质量和热情之间存在密切关系的证据，
