Insomnia and impulsive buying under abusive supervisors: Mediation of ego depletion and moderation of coworker support
研究上级辱虐管理对一线服务员工失眠和冲动购买的长期影响，发现工作不安全和自我损耗是中介机制，同事情感支持缓解而工具支持加剧了这些负面效应。
Abstract Compared with the vast amount of research on the deleterious effects of abusive supervision on work outcomes, its effect on off‐job behavior has received little scholarly attention. To bridge this gap, we examined the long‐term effects of abusive supervision on subsequent insomnia and impulsive buying among frontline service employees (FSEs). We focused on the mediating roles of job insecurity and ego depletion, and the moderating roles of coworker emotional and instrumental support. To test our hypotheses, we collected three‐wave data 3 months apart from 318 FSEs. As hypothesized, FSEs' experiences of abusive supervision significantly affected insomnia and impulsive buying 6 months later. Job insecurity and ego depletion sequentially mediated these relationships. Although coworker emotional support mitigated the deleterious effects of abusive supervision on insomnia and impulsive buying through job insecurity and ego depletion, coworker instrumental support aggravated these effects. These findings contribute to the literature by providing novel insights into the role of abusive supervision in maladaptive off‐job behavior and its boundary conditions.
