Workplace violence is a work stressor which is presumed to lead to burnout, whereas social support is hypothesized to buffer the impact of such a stressor on health outcomes. In this study the association between burnout and workplace violence was investigated, and the role played by social support in moderating the relationship assessed. The study group consisted of workers in the road passenger transport sector in Maputo City, Mozambique.
A random sample of 504 participants was selected from a register of 2,618 drivers and conductors working with road passenger transport. The study design was cross-sectional. Previously validated measures of burnout, workplace violence and social support were used.
The prevalence of severe burnout was 3.6% and of mild burnout 30.1%. Workplace violence was significantly associated with burnout after control for potential confounders. Burnout was more common among workers lacking social support following workplace violence than among peers who had received supported following an incident of violence.
The study suggests that burnout is a public health problem among workers in the road passenger transport sector, and may be closely and independently linked to workplace violence. Social support appears to buffer or moderate the effect of workplace violence on burnout. This has implications for policy in the workplace. Strategies and guidelines are needed to support workers following workplace violence, since these may prove vital in reducing burnout and other psychosocial consequences.
工作场所暴力是一种工作压力源，据推测会导致倦怠，而社会支持则被假设可以缓冲这种压力源对健康结果的影响。本研究调查了倦怠与工作场所暴力之间的关系，并评估了社会支持在调节这种关系中所起的作用。研究对象为莫桑比克马普托市道路客运部门的工作人员。
从 2618 名驾驶员和售票员的登记册中随机抽取了 504 名参与者作为研究样本。研究设计为横断面研究。使用了先前经过验证的倦怠、工作场所暴力和社会支持测量方法。
严重倦怠的患病率为 3.6%，轻度倦怠的患病率为 30.1%。在控制了潜在混杂因素后，工作场所暴力与倦怠显著相关。与在遭受暴力事件后得到支持的同行相比，在工作场所遭受暴力后缺乏社会支持的工人中，倦怠更为常见。
本研究表明，倦怠是道路客运部门工作人员的一个公共卫生问题，并且可能与工作场所暴力密切相关且独立相关。社会支持似乎缓冲或调节了工作场所暴力对倦怠的影响。这对工作场所的政策具有影响。需要制定支持工作场所暴力后工人的策略和指南，因为这可能对减少倦怠和其他心理社会后果至关重要。
