To explore the role of social integration and support in the longitudinal course of suicidal ideation (SI) in a rural population.
Baseline and 12-month data were obtained from participants within the Australian Rural Mental Health Study, a longitudinal study of community residents within rural and remote New South Wales, Australia. SI was assessed using the Patient Health Questionnaire. Individual psychological factors, family and community characteristics were examined alongside personal social networks (Berkman Syme Social Network Index), availability of social support (Interview Schedule for Social Interaction) and perception of local community (Sense of Community Index).
Thirteen hundred and fifty-six participants were included in the analysis (39% male, mean age 56.5 years). Sixty-one participants reported recent SI at baseline, while 57 reported SI at follow-up. Baseline SI was a strong predictor of SI at 12 months [odds ratio (OR) 19.0, 95% confidence interval (CI) 8.6-42.3); significant effects were also observed for baseline values of psychological distress (OR 1.4, 95% CI 1.0-1.9) and availability of social support (OR 0.76, 95% 0.58-1.0) on 12-month SI. The emergence of SI at 12-month follow-up was predicted by higher psychological distress (OR 1.8, 95% CI 1.3-2.4); there was a marginal effect of lower availability of support (OR 0.74, 95% CI 0.55-1.0); neither of these variables predicted SI resolution.
This study investigated factors associated with SI over a 12-month period in a rural cohort. After controlling for known risk factors for SI, low availability of social support at baseline was associated with greater likelihood of SI at 12-month follow-up.
探讨社会融合和支持在农村人群自杀意念（SI）纵向病程中的作用。
本研究的数据来自澳大利亚农村心理健康研究的参与者，这是一项对澳大利亚新南威尔士州农村和偏远地区社区居民进行的纵向研究。使用患者健康问卷评估 SI。个体心理因素、家庭和社区特征，以及个人社交网络（Berkman Syme 社会网络指数）、社会支持的可及性（访谈式社会互动量表）和对当地社区的感知（社区感指数）均被纳入研究。
共有 1356 名参与者被纳入分析（39%为男性，平均年龄 56.5 岁）。61 名参与者在基线时报告有近期 SI，而 57 名参与者在随访时报告有 SI。基线 SI 是 12 个月时 SI 的强烈预测因素[比值比（OR）19.0，95%置信区间（CI）8.6-42.3]；基线时心理困扰（OR 1.4，95%CI 1.0-1.9）和社会支持的可及性（OR 0.76，95%CI 0.58-1.0）也对 12 个月时的 SI 有显著影响。12 个月随访时出现 SI 的预测因素是更高的心理困扰（OR 1.8，95%CI 1.3-2.4）；社会支持的可及性较低（OR 0.74，95%CI 0.55-1.0）有边缘效应；这两个变量都没有预测 SI 的缓解。
本研究调查了农村队列中 12 个月内与 SI 相关的因素。在控制 SI 的已知危险因素后，基线时社会支持的可用性较低与 12 个月随访时 SI 的可能性增加相关。
