The purpose of this study was to determine whether mood instability in people with anxiety disorders contributes to trait impulsivity, non-suicidal self-injury, and binge eating/purging.
Data were analysed from a general population sample of 7,221 adults (M = 51.0 years; 56.9% female). Logistic regression analyses with effect decompositions were used to establish the associations of five anxiety disorders (generalized anxiety disorder, social phobia, panic disorder, agoraphobia, and obsessive-compulsive disorder) with impulsivity, non-suicidal self-injury, and binge eating/purging, and then to determine the extent that adding mood instability to each model reduced these relationships.
Participants with an anxiety disorder were more likely to report impulsivity compared to participants without an anxiety disorder (ORs = 2.40-3.92, all p < .001), but these relationships reduced by 59-78% and became non-significant when mood instability was added to the models. Participants with an anxiety disorder were also more likely to report non-suicidal self-injury (ORs = 3.86-18.9, all p < .001) and binge eating/purging (ORs = 4.05-14.9, all p < .01); adding mood instability to the models reduced these relationships by at least 30%.
Mood instability and impulsivity are common in people with anxiety disorders. Anxiety disorders are associated with impulsivity largely because of the association between mood instability and impulsivity. Mood instability may contribute to non-suicidal self-injury and binge eating/purging in people with anxiety disorders. Treatments for mood instability in addition to standard anxiety disorder treatment may reduce impulsivity, non-suicidal self-injury, and binge eating/purging in people with anxiety disorders.
Many patients with anxiety disorders experience mood instability, which is associated with impulsivity, non-suicidal self-injury, and binge eating/purging. Treating mood instability alongside anxiety may help reduce impulsivity, non-suicidal self-injury, and binge eating/purging in people with anxiety disorders.
本研究旨在确定焦虑障碍患者的情绪不稳定是否会导致特质冲动、非自杀性自伤和暴食/清除行为。
对 7221 名成年人（平均年龄为 51.0 岁；56.9%为女性）的一般人群样本进行数据分析。采用逻辑回归分析和效应分解来确定五种焦虑障碍（广泛性焦虑障碍、社交恐惧症、惊恐障碍、广场恐惧症和强迫症）与冲动、非自杀性自伤和暴食/清除行为的关系，然后确定将情绪不稳定因素加入到每个模型中会如何减少这些关系。
与没有焦虑障碍的参与者相比，患有焦虑障碍的参与者更有可能报告存在冲动（比值比[ORs]为 2.40-3.92，均 P<.001），但当将情绪不稳定因素加入到模型中时，这些关系减少了 59-78%，且变得不显著。患有焦虑障碍的参与者也更有可能报告非自杀性自伤（ORs 为 3.86-18.9，均 P<.001）和暴食/清除行为（ORs 为 4.05-14.9，均 P<.01）；将情绪不稳定因素加入到模型中至少减少了 30%这些关系。
情绪不稳定和冲动在患有焦虑障碍的人群中很常见。焦虑障碍与冲动之间的关联主要是由于情绪不稳定和冲动之间的关联。情绪不稳定可能导致患有焦虑障碍的人出现非自杀性自伤和暴食/清除行为。除了标准的焦虑症治疗之外，治疗情绪不稳定可能会减少患有焦虑症患者的冲动、非自杀性自伤和暴食/清除行为。
许多患有焦虑障碍的患者会经历情绪不稳定，这与冲动、非自杀性自伤和暴食/清除行为有关。在治疗焦虑症的同时治疗情绪不稳定可能有助于减少患有焦虑症患者的冲动、非自杀性自伤和暴食/清除行为。
