Suicidal ideation has been linked to a bias toward interpreting ambiguous information in consistently less positive or more negative manners (positive/negative interpretation bias), implying that information-processing biases might distort beliefs thought to inspire suicidal ideation (e.g., those regarding burdensomeness). Therefore, in the present study, we examined whether suicidal ideation and beliefs highlighted in theories of suicide are related to positive/negative interpretation bias and/or a bias against revising negative interpretations in response to evidence against them (negative interpretation inflexibility). Data were collected in three waves, each 1 week apart. Network analyses and structural equation models provided evidence that negative interpretation bias (cross-sectionally) and negative interpretation inflexibility (cross-sectionally and over time) were related to suicidal ideation and that the latter relationship was mediated by perceived burdensomeness. By identifying this mediation pathway in the present study, we provide a potential mechanism by which perceptions of burdensomeness, a key risk factor for suicidality, might arise and/or persist.

自杀意念已与偏向于以持续较少积极或消极的方式来解释歧义信息的偏见有关（正/负解释偏见），这意味着信息处理偏见可能会扭曲被认为激发自杀意念的信念（例如，有关沉重负担的观念）。因此，在本研究中，我们研究了自杀理论中强调的自杀意念和信念是否与积极/消极的解释偏见和/或反对对消极的解释进行修改以应对反对他们的证据有关的否定（消极的解释缺乏灵活性））。数据收集分为三个阶段，每个阶段相隔1周。网络分析和结构方程模型提供了证据，负解释偏见（横断面）和负解释僵化（横断面和随着时间的推移）与自杀观念有关，并且后者的关系是由感知的负担造成的。通过确定本研究中的这种调解途径，我们提供了一种潜在的机制，通过这种机制，可能会产生和/或持续存在对自杀倾向（自杀的关键危险因素）的感知。
