This study investigated the cross-cultural relevance and validity of the Interpersonal Theory of Suicide (ITS) utilizing young adult samples from South Korea (n =554) and the United States (U.S.; n =390). To examine the ITS, all participants completed self-report questionnaires measuring Thwarted Belongingness, Perceived Burdensomeness, and Capability for Suicide. We examined whether each construct significantly predicted the severity of suicidal risk in both samples. We also determined whether the strength of the effects of Thwarted Belongingness and Perceived Burdensomeness on suicidal ideation differed between the two samples due to the greater degree of importance placed on interpersonal relationships in collectivistic cultures such as South Korea. Structural equation modeling was used to examine these hypotheses. Thwarted Belongingness, Perceived Burdensomeness, and Capability for Suicide significantly predicted elevated suicidal risk. However, there were no significant differences in the paths from Thwarted Belongingness or Perceived Burdensomeness to suicide risk between the South Korean and U.S.
These findings support the cross-cultural relevance and applicability of the ITS, whereby Thwarted Belongingness and Perceived Burdensomeness serve as indicators of suicide risk in both Western (U.S.) and East Asian (Korean) samples.
本研究利用来自韩国（n=554）和美国（n=390）的青年成年人样本，调查了人际理论自杀（ITS）的跨文化相关性和有效性。为了检验 ITS，所有参与者都完成了自我报告问卷，测量了归属感被剥夺感、被累赘感和自杀能力。我们检验了每个结构在两个样本中是否都能显著预测自杀风险的严重程度。我们还确定了由于韩国等集体主义文化更重视人际关系，归属感被剥夺感和被累赘感对自杀意念的影响程度是否存在差异。结构方程模型被用于检验这些假设。归属感被剥夺感、被累赘感和自杀能力显著预测了自杀风险的增加。然而，在韩国和美国样本中，从归属感被剥夺感或被累赘感到自杀风险的路径没有显著差异。
这些发现支持了 ITS 的跨文化相关性和适用性，即归属感被剥夺感和被累赘感在西方（美国）和东亚（韩国）样本中都是自杀风险的指标。
