This dissertation by Rebecca Bryant (2009) analyzes the presence of Common Method Variance (CMV) in the relationships between work-family conflict, personality traits, and coping styles among 204 employee-significant other pairs. The study reveals significant insights, showing that 75% of correlations between work-family conflict and both personality and coping styles were not significant. The findings challenge assumptions about self-reported data, suggesting that single-source correlations do not consistently inflate results due to CMV, urging a re-evaluation of methodological approaches in similar research.

Does CMV Exist? • Rebecca Bryant’s Dissertation, 2009 • 40 page introduction • Established expected relationships • Work-family Conflict • Personality • Coping Style • N = 204 employee-significant other pairs
Do Variables Correlate Within Method? • Percent of nonsignificant correlations • WFC and personality: 75% (6 of 8) • WFC and coping: 75% (18 of 24)
Conclusion • Not everything self-reported is related • Single source correlations not always bigger • Therefore, there is no constant inflation due to CMV
