Research has established pairwise relationships between suicidal ideation (SI), low Body Trust, elevated agitation, and eating disorders, but knowledge of how these aspects relate in a single model is lacking. This study tested an indirect pathway with low Body Trust relating to severity of SI via agitation in a clinical eating disorder sample.
Participants (N = 319; 92.8% female; 93.4% Caucasian; mean age 21.8 years) were adults currently receiving specialized eating disorder treatment (44.3% intensive outpatient or higher level-of-care) who completed online self-report measures of study variables. The PROCESS macro was utilized to test proposed pathways.
Low Body Trust was significantly directly associated with increased severity of current SI, both before (B = -.89, p < .001) and after (B = -.51, p = .001) accounting for the indirect effect through agitation, also significant (B = -.37, SE = .06, CI -.52 to -.26).
Perception of the body as unsafe may be related to agitation, and this intolerable sensation of trapped arousal could contribute to a desire to die. Future work should investigate these relationships prospectively to determine the relevance of Body Trust for assessment and treatment of suicide-related factors among individuals with eating disorders.
研究已经确立了自杀意念（SI）、低身体信任、情绪激动和饮食失调之间的两两关系，但对于这些方面如何在单一模型中相关的了解还很缺乏。本研究在一个临床饮食失调样本中，检验了低身体信任通过情绪激动与 SI 严重程度相关的间接途径。
参与者（N=319；92.8%为女性；93.4%为白种人；平均年龄 21.8 岁）为目前正在接受专门饮食失调治疗的成年人（44.3%为强化门诊或更高水平的护理），他们在线完成了研究变量的自我报告测量。使用 PROCESS 宏检验了所提出的途径。
低身体信任与当前 SI 严重程度显著直接相关，无论是在考虑到通过激动产生的间接效应之前（B=-.89，p<.001）还是之后（B=-.51，p=.001）都是如此，这一间接效应也具有显著性（B=-.37，SE=.06，CI-.52 至-.26）。
将身体视为不安全可能与情绪激动有关，而这种被束缚的觉醒的无法忍受的感觉可能会导致想死的欲望。未来的研究应该前瞻性地调查这些关系，以确定身体信任对于评估和治疗饮食失调个体中与自杀相关因素的相关性。
