: Self-perceived burden and perceived burdensomeness are two apparently related constructs that have arisen independently from research in physical and mental health, respectively. Although both are associated with suicidal ideation in individuals with chronic pain, they have yet to be examined concurrently in the same group of patients. : The aim of this study was to investigate the relationship between the two constructs and their differential prediction of suicidal ideation. : Participants were 260 outpatients of an interdisciplinary chronic pain treatment program. Each participant completed the Self-Perceived Burden Scale (SPBS), the Interpersonal Needs Questionnaire Perceived Burdensomeness Scale (INQPBS), the Beck Scale for Suicide Ideation, and the thoughts of self-harm item of the Patient Health Questionnaire-9. : The SPBS and the INQPBS were both unifactorial measures with good internal consistency. They correlated significantly with one another ( = 0.50, < 0.001), as well as with scores on the two measures of suicidal ideation (s ranging from 0.29 to 0.62, s < 0.001). However, the INQPBS correlated more highly with suicidal ideation than did the SPBS. In regression analyses, the INQPBS predicted unique variance in suicidal ideation after adjusting for the SPBS. Conversely, the SPBS did not contribute uniquely when the INQPBS was entered first. : Patients with chronic pain who believe that they have become "a burden to others" are at increased risk for suicidal ideation. The conceptual similarities and differences between the constructs of self-perceived burden and perceived burdensomeness are reviewed to explain why perceived burdensomeness is the stronger predictor of this increased risk.
自我感知负担和感知累赘是两个明显相关的概念，它们分别独立产生于身心健康方面的研究。虽然两者都与慢性疼痛患者的自杀意念相关，但尚未在同一组患者中同时进行研究。
本研究的目的是调查这两个概念之间的关系及其对自杀意念的差异预测。
研究对象为一个跨学科慢性疼痛治疗项目的260名门诊患者。每位参与者都完成了自我感知负担量表（SPBS）、人际需求问卷感知累赘量表（INQPBS）、贝克自杀意念量表以及患者健康问卷-9中的自我伤害想法项目。
SPBS和INQPBS均为单因素测量工具，具有良好的内部一致性。它们彼此之间显著相关（r = 0.50，p < 0.001），并且与两种自杀意念测量工具的得分也显著相关（r值范围为0.29至0.62，p < 0.001）。然而，INQPBS与自杀意念的相关性高于SPBS。在回归分析中，调整SPBS后，INQPBS预测了自杀意念中的独特方差。相反，当先纳入INQPBS时，SPBS并没有独特的贡献。
认为自己已成为“他人负担”的慢性疼痛患者自杀意念风险增加。本文回顾了自我感知负担和感知累赘这两个概念的异同，以解释为何感知累赘是这种风险增加的更强预测因素。
