Using an interpersonal theory of suicide and affect regulation framework, we investigated the relationships between perceived burdensomeness, thwarted belongingness, weight stigmatization, emotion dysregulation, eating pathology, and suicide risk. Three main hypotheses were investigated. First, we predicted a positive linear relationship between weight stigmatization and risk. Second, an indirect effect of weight stigmatization on risk via perceived burdensomeness and thwarted belongingness was posited. Third, we hypothesized that weight stigmatization would indirectly affect suicide risk via emotion dysregulation and eating pathology. Undergraduates (N = 156) completed online surveys. Linear regressions and indirect effect analyses were performed. Weight stigmatization was directly, positively associated with increased suicide risk. Weight stigmatization indirectly affected suicide risk via perceived burdensomeness but not thwarted belongingness. Higher stigmatization was associated with higher levels of perceived burdensomeness, which was associated with higher risk. An indirect effect of weight stigmatization on suicide risk through emotional dysregulation emerged. Higher weight stigmatization was associated with higher emotional dysregulation, which was associated with higher suicide risk. When all models were combined, only an indirect effect via perceived burdensomeness remained. Our findings may have clinical and public health implications for suicide prevention among people with weight stigma-related risk factors.

使用自杀的人际关系理论和影响调节框架，我们调查了感知负担、阻碍归属感、体重污名化、情绪失调、饮食病理和自杀风险之间的关系。研究了三个主要假设。首先，我们预测了体重污名化和风险之间的正线性关系。其次，假设体重污名化通过感知到的负担和阻碍归属感对风险产生间接影响。第三，我们假设体重污名化会通过情绪失调和饮食病理间接影响自杀风险。本科生（N = 156) 已完成在线调查。进行了线性回归和间接影响分析。体重污名化与自杀风险增加直接、正相关。体重污名化通过感知负担间接影响自杀风险，但不会阻碍归属感。更高的污名与更高水平的负担感相关，而这与更高的风险相关。通过情绪失调，体重污名化对自杀风险的间接影响出现了。较高的体重污名与较高的情绪失调有关，而后者与较高的自杀风险有关。当所有模型结合在一起时，只剩下通过感知负担产生的间接影响。
