Suicide remains a significant public health concern globally, with unemployment, financial hardship, and employment transitions cited as contributing factors. However, their causal association remains unclear. This study investigates the causal association between employment transitions and suicide in Australia from 2009 to 2018, utilising Convergent Cross Mapping (CCM), a dynamical systems approach. Employment transitions were categorised into positive transition, no transition, and negative transition groups, representing changes in employment status. Initial analysis of raw data suggested all three groups showed causal association to suicide. However, detrending the time series revealed that only negative transition maintained a significant causal association with suicide, while no transition and positive transition showed no causal association. These findings emphasise the critical association of employment instability on mental health and the importance of stable or improving employment conditions in suicide prevention. The study discusses the need for targeted interventions to mitigate the adverse effects of employment downturns.
自杀仍然是全球重大的公共卫生问题,失业、经济困难和就业转变被认为是促成因素。然而,它们之间的因果关系仍不明确。本研究利用一种动态系统方法——收敛交叉映射(CCM),调查了2009年至2018年澳大利亚就业转变与自杀之间的因果关系。就业转变被分为正向转变、无转变和负向转变组,代表就业状况的变化。对原始数据的初步分析表明,所有三组都显示出与自杀的因果关系。然而,对时间序列进行去趋势处理后发现,只有负向转变与自杀保持着显著的因果关系,而无转变和正向转变则没有因果关系。这些发现强调了就业不稳定与心理健康的关键关联,以及稳定或改善就业条件在预防自杀中的重要性。该研究讨论了采取有针对性干预措施以减轻就业低迷负面影响的必要性。
