Perceived autonomy support at work and romantic relationship conflict: The mediating role of controlling behavior

This study examined whether controlling behavior mediates the relationship between perceived autonomy support at work and romantic relationship conflict, based on Self-Determination Theory (SDT) and the spillover–crossover model. Using a quantitative correlational design, WCQ, CBS-R, and RPCS scales were employed on 223 employed adults (111 males, 112 females; 18–45 years) in committed relationships. Perceived autonomy support was significantly negatively correlated with controlling behavior (ρ = –.534, p < .001) and relationship conflict (ρ = –.288, p < .01). Regression showed that autonomy support predicted controlling behavior (R² = .247) and conflict (R² = .061), and controlling behavior predicted conflict (R² = .131). Mediation analysis indicated a significant indirect effect (–1.44, 95% CI [–2.02, –0.89]), with the direct effect becoming non-significant, demonstrating full mediation. No gender differences were found. Lower autonomy support at work was linked to greater controlling behavior, which increased relationship conflict, highlighting workplace autonomy support as an indirect protective factor for relationship quality.
