Insomnia and affective temperaments influence depressive symptoms in the general population. However, the ways in which the interaction between insomnia and affective temperaments affects depressive symptoms remains unknown. We studied the moderating effects of affective temperaments on the relationship between insomnia and depressive symptoms in adult community volunteers.
The participants were recruited from a community in Japan (n = 525). The Athens Insomnia Scale; Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Auto-questionnaire version; and Patient Health Questionnaire-9 were used to evaluate insomnia, affective temperaments, and depressive symptoms, respectively. A hierarchical multiple regression analysis were conducted to evaluate the interactions.
Insomnia significantly and positively interacted with cyclothymic, depressive, and anxious temperaments with regard to depressive symptoms, while insomnia significantly and negatively interacted with hyperthymic temperament on depressive symptoms. No significant interaction between insomnia and irritable temperament with regard to depressive symptoms were observed.
Since the participants were adult community volunteers in Japan, the results may not be generalizable to other communities.
This study suggests that the influence of insomnia on depressive symptoms is moderated positively by cyclothymic, depressive, and anxious temperament and negatively by hyperthymic temperament. In adult community volunteers, affective temperaments may moderate the influence that insomnia has on depressive symptoms. Therefore, it may be useful to consider affective temperaments while dealing with depressive symptoms associated with insomnia.
失眠和情感气质会影响普通人群的抑郁症状。然而，失眠和情感气质之间的相互作用如何影响抑郁症状尚不清楚。我们研究了情感气质对成年社区志愿者中失眠与抑郁症状之间关系的调节作用。
参与者来自日本的一个社区（n=525）。采用雅典失眠量表、孟菲斯、比萨、巴黎和圣地亚哥自动问卷版情绪评估量表和患者健康问卷-9 分别评估失眠、情感气质和抑郁症状。采用分层多重回归分析评估交互作用。
失眠与环性、抑郁和焦虑气质对抑郁症状呈显著正交互作用，而失眠与兴奋气质对抑郁症状呈显著负交互作用。失眠与易激惹气质对抑郁症状无显著交互作用。
由于参与者是日本成年社区志愿者，因此结果可能不适用于其他社区。
本研究表明，失眠对抑郁症状的影响受环性、抑郁和焦虑气质的正向调节，受兴奋气质的负向调节。在成年社区志愿者中，情感气质可能调节失眠对抑郁症状的影响。因此，在处理与失眠相关的抑郁症状时，考虑情感气质可能是有用的。
