Sleep deprivation has in several studies been found to increase anxiety. However, the extent to which this anxiogenic effect depends on one's underlying trait anxiety has not previously been determined. Using two separate sleep-loss experiments, the current research investigated whether trait anxiety (STAI-T) moderates the increase in state anxiety (STAI-S) following one night of total sleep loss (study 1, = 182, age 25.3 ± 6.5, 103 women) and two nights of partial sleep restriction (study 2, = 67, age 26.5 ± 7.4, 38 women). Both studies showed the expected anxiogenic effect of sleep loss, and a clear relationship between trait anxiety and state anxiety. However, the anxiogenic effect of sleep loss was not moderated by trait anxiety, as there was an equal impact regardless of trait anxiety level. These findings indicate that, although sleep loss is related to general anxiety as well as anxiety disorders, for a non-clinical sample the anxiogenic effect of short-term sleep loss is not affected by baseline levels of anxiety.
在多项研究中发现，睡眠剥夺会增加焦虑感。然而，这种致焦虑效应在多大程度上取决于个体潜在的特质焦虑，此前尚未确定。通过两项独立的睡眠剥夺实验，本研究调查了特质焦虑（状态 - 特质焦虑量表 - 特质分量表，STAI - T）是否会调节在经历一晚完全睡眠剥夺（研究1，n = 182，年龄25.3 ± 6.5岁，103名女性）和两晚部分睡眠限制（研究2，n = 67，年龄26.5 ± 7.4岁，38名女性）后状态焦虑（状态 - 特质焦虑量表 - 状态分量表，STAI - S）的增加情况。两项研究均显示出预期的睡眠剥夺致焦虑效应，以及特质焦虑与状态焦虑之间的明显关系。然而，睡眠剥夺的致焦虑效应并未受到特质焦虑的调节，因为无论特质焦虑水平如何，其影响都是相同的。这些发现表明，虽然睡眠剥夺与一般焦虑以及焦虑症有关，但对于非临床样本而言，短期睡眠剥夺的致焦虑效应不受焦虑基线水平的影响。
