To explore the association between loneliness and efficacy to engage in health behaviors that are known to reduce the risk of early mortality in people with serious mental illness (SMI). This secondary data analysis was based on a cross-sectional study of 113 participants with SMI residing in New Hampshire. Ordinary Least Squares regressions were used to examine bivariate relationships between variables of interest. Participants had a primary mental health diagnosis of major depressive disorder (37.2%), schizophrenia spectrum disorder (28.3%), bipolar disorder (29.2%), or posttraumatic stress disorder (5.3%). High levels of loneliness were associated with low levels of self-efficacy to manage chronic diseases ( p = 0.0001), as well as low levels of self-efficacy to manage psychological well-being ( R 2 = .31; F = 9.49, p = 0.0001; RMSE = 1.66). Loneliness may serve as a barrier to healthy behaviors, and thus, contribute to early mortality among people with SMI. The growing body of literature that demonstrates the importance of addressing loneliness in people with SMI should stimulate policymakers and researchers to target loneliness as a mechanism to address early mortality in people with SMI.

患有严重精神疾病的人的孤独感及其与健康行为的关联

探索孤独与参与已知可降低严重精神疾病 (SMI) 患者早期死亡风险的健康行为的功效之间的关联。该次要数据分析基于对居住在新罕布什尔州的 113 名 SMI 参与者的横断面研究。普通最小二乘回归用于检查感兴趣变量之间的双变量关系。参与者的主要心理健康诊断为重度抑郁症（37.2%）、精神分裂症谱系障碍（28.3%）、双相情感障碍（29.2%）或创伤后应激障碍（5.3%）。高水平的孤独感与管理慢性病的低水平自我效能相关（p = 0.0001），以及管理心理健康的低水平自我效能（R 2 = .31；F = 9.49，p = 0.0001；RMSE = 1.66）。孤独可能成为健康行为的障碍，因此会导致 SMI 患者的早期死亡。越来越多的文献证明了解决 SMI 患者孤独感的重要性，这应该会刺激政策制定者和研究人员将孤独感作为解决 SMI 患者早期死亡的一种机制。
