The present study examined the relations among sex, work-family conflict, and psychological distress in 78 Canadian police officers (50 men and 28 women). The average age of the officers was 36.1 yr. (SD=8.0), and nearly one-third of the respondents had been in policing 16 years or more. Ordinary least-squares regression was conducted to examine the association of Psychological Distress scores, as measured by the K6, with four types of work-family conflict: Time-based Work-to-Family Conflict, Time-based Family-to-Work Conflict, Strain-based Work-to-Family Conflict, and Strain-based Family-to-Work Conflict. Being single and having higher perceived Strain-based Work-to-Family Conflict were associated with greater scores on Psychological Distress. No statistically significant sex differences emerged in the self-reported type or direction of work-family conflict or in the factors associated with Psychological Distress.
