High rates of suicidal ideation in those with social anxiety disorder (SAD) have been attributed to feelings of thwarted belongingness and perceived burdensomeness, but most work has been in non-clinical samples. We assessed the contributions of thwarted belongingness and perceived burdensomeness to suicidal ideation severity, over clinical covariates, in individuals diagnosed with SAD.
Participants were 58 adult outpatients (mean age 25.62 years, 69% female) with SAD. Hierarchical linear regression assessed contributions of thwarted belongingness and perceived burdensomeness to suicidal ideation, before and after covarying other potential explanatory variables (depression, agitation, brooding rumination).
Perceived burdensomeness was significantly positively related to suicidal ideation severity (p < .001) above thwarted belongingness, which was not incremental (p = .791). The same pattern was found after inclusion of additional covariates (perceived burdensomeness p = .006; thwarted belongingness p = .757). Greater agitation also uniquely accounted for more severe suicidal ideation (p = .001).
This study was cross-sectional, did not assess all potential confounding variables, and utilized a treatment-seeking sample.
Results suggest perceived burdensomeness is independently related to suicidal ideation severity in SAD, over thwarted belongingness and other clinical features. Future work should seek to replicate these findings and evaluate causal, longitudinal relationships among perceived burdensomeness, agitation, and severity of suicidal ideation in those with SAD in order to determine whether these may be clinically-relevant mechanisms.
社交焦虑障碍（SAD）患者的自杀意念发生率较高，这归因于归属感受挫和被认为是负担的感觉，但大多数工作都是在非临床样本中进行的。我们评估了归属感受挫和被认为是负担感对 SAD 患者自杀意念严重程度的影响，这些影响超过了临床协变量。
参与者是 58 名患有 SAD 的成年门诊患者（平均年龄 25.62 岁，69%为女性）。分层线性回归评估了归属感受挫和被认为是负担感对自杀意念的贡献，在协变量（抑郁、激动、沉思性反刍）之后进行。
被认为是负担感与自杀意念严重程度呈显著正相关（p<0.001），超过归属感受挫，而且没有增量效应（p=0.791）。在纳入其他额外协变量后，也发现了同样的模式（被认为是负担感 p=0.006；归属感受挫 p=0.757）。更大的激动也可以独特地解释更严重的自杀意念（p=0.001）。
本研究是横断面的，没有评估所有潜在的混杂变量，并且使用了寻求治疗的样本。
结果表明，在 SAD 中，与归属感受挫和其他临床特征相比，被认为是负担感与自杀意念严重程度独立相关。未来的工作应该复制这些发现，并评估在 SAD 患者中，被认为是负担感、激动和自杀意念严重程度之间的因果、纵向关系，以确定这些是否是临床上相关的机制。
