Previous research on law enforcement officers has not included studies of marital relationships from the spouse perspective, and tend to focus on workplace-based manifestations of stress and other health issues. This study fills a gap in current research by surveying police wives about their personal experiences of marriage to law enforcement officers, and mental health as it relates to themselves and their husbands. We examined the association of mental health stigma with marital quality in a sample of 969 police wives. We found a significant negative association between wives’ perceptions of police officers’ mental health stigma and marital quality, and additionally that wife characteristics of positive emotion and reappraisal are positively associated with marital quality, but do not act as moderators. We also discussed methods of reducing negative impacts of mental health stigma on marital quality, specifically mandatory police officer counseling and marital quality interventions.
