目的：探究抑郁发作患者自杀意念与认知融合和经验性回避之间的关系。方法：采用随机抽样的方 法纳入160例抑郁发作患者，使用一般人口学问卷、贝克自杀意念量表中文版、认知融合问卷（中文版）、接 纳与行动问卷第二版（中文版）进行调查，分析自杀意念与认知融合和经验性回避的关系。结果：有无自杀 意念的抑郁发作患者在受教育年限、职业、婚姻、受虐待史、认知融合、经验性回避的差异有统计学意义（均 P＜0.05）。自杀意念强度与认知融合（OR=0.287，P＜0.05）和经验性回避（OR=0.349，P＜0.05）呈正相关。 在认知融合方面，“中等到强烈”的“被动尝试自杀的愿望”与“无”和“弱”的差异有统计学意义（P＜0.05）；在 经验性回避方面，“中等到强烈”的“主动尝试自杀的愿望”和“被动尝试自杀的愿望”与“无”和“弱”的差异 有统计学意义（P＜0.05）。二元Logistics回归显示，受教育年限越短，自杀意念发生率越高（OR=0.781，95% CI 0.661～0.922，P=0.004），经验性回避越高，自杀意念发生率越高（OR=1.150，95%CI 1.055～1.255，P= 0.002）。结论：认知融合和经验性回避均与抑郁发作患者的自杀意念强度呈正相关，经验性回避是抑郁发 作患者自杀意念的风险因素。

To explore the relationship between suicidal ideation and cognitive fusion and experiential avoidance in patients with depressive episodes. Methods: A total of 160 patients with depressive episode were enrolled by random sampling method. The general demographic questionnaire, Beck Suicidal Ideation Scale-Chinese version (BSI-CV), Cognitive Fusion Questionnaire (CFQ), Acceptance and Action Questionnaire-second version (AAQ-II) were used to investigate the relationship between suicidal ideation and cognitive fusion and empirical avoidance. Results: There were significant differences in years of education, occupation, marriage, history of abuse, cognitive fusion and experiential avoidance between patients with and without suicidal ideation (P<0.05). The intensity of suicidal ideation was positively correlated with cognitive fusion(OR=0.287, P<0.05) and experiential avoidance (OR=0.349, P<0.05). For cognitive fusion, the "moderate to strong" "desire to passively attempt suicide" was statistically significantly different from "none" and "weak" (P<0.05). For experiential avoidance, the "moderate to strong" "desire to actively attempt suicide" and "desire to passively attempt suicide" were statistically significantly different from "none" and "weak"(P<0.05). Binary Logistics regression showed that the shorter the years of education, the higher the incidence of suicidal ideation (OR=0.781, 95%CI 0.661～0.922, P=0.004); the higher the experiential avoidance, the higher the incidence of suicidal ideation (OR=1.150, 95% CI 1.055～1.255, P=0.002). Conclusion: Both cognitive fusion and experiential avoidance are positively correlated with the intensity of suicidal ideation in patients with depressive episode, and experiential avoidance is a risk factor for suicidal ideation in patients with depressive episode.
