心理僵化是接纳与承诺疗法(ACT)模型中的一个核心概念。目前的研究假设并测试了两个模型，在这些模型中，心理不灵活与更高水平的抑郁症状和睡眠困难有关。为了获得数据，日本大学生(N=2633)完成了与心理僵化、抑郁症状和睡眠困难有关的问卷调查。心理不灵活与较高的抑郁症状(r=0.61)和睡眠困难(r=0.39)显著相关。结构方程模型显示，在控制了睡眠困难的影响后，心理不灵活与更高水平的抑郁症状有关。此外，在控制了抑郁症状的影响后，心理不灵活与更高水平的睡眠困难相关。这些发现可能有助于激励临床医生使用ACT治疗失眠。目前的研究发现，心理上的不灵活程度越高，抑郁症状和睡眠困难的程度越高。这些发现可能有助于激励临床医生使用ACT治疗失眠。
Psychological inflexibility is a core concept in the acceptance and commitment therapy (ACT) model. The current study hypothesized and tested two models in which psychological inflexibility was linked with higher levels of depressive symptoms and sleep difficulty. To attain data, Japanese university students (N = 633) completed questionnaires related to psychological inflexibility, depressive symptoms, and sleep difficulty. Psychological inflexibility was significantly correlated with higher levels of both depressive symptoms (r = 0.61) and sleep difficulty (r = 0.39). Structural equation modeling showed that psychological inflexibility was associated with higher levels of depressive symptoms after controlling for the effect of sleep difficulty. Additionally, psychological inflexibility was correlated with higher levels of sleep difficulty after controlling for the effect of depressive symptoms. These findings might assist with motivating clinicians to use ACT for insomnia. The current study found that greater psychological inflexibility was linked with high levels of depressive symptoms and sleep difficulties. These findings might assist with motivating clinicians to use ACT for insomnia.
