Cautious to a Fault: Self-Protection and the Trajectory of Marital Satisfaction.

A contextual model of self-protection is proposed to explain when adhering to cautious "if-then" rules in daily interaction erodes marital satisfaction. People can self-protect against partner non-responsiveness by distancing when a partner seems rejecting, promoting a partner's dependence when feeling unworthy, or by devaluing a partner in the face of costs. The model implies that being less trusting elicits self-protection, and that mismatches between self-protective practices and encountered risk accelerate declines in satisfaction. A longitudinal study of newlyweds revealed that the fit between self-protection practices and risk predicted declines in satisfaction over three years. When people self-protected more initially, satisfaction declined more in low-risk (i.e., low conflict, resilient partner) than high-risk relationships (i.e., high conflict, vulnerable partner). However, when people self-protected less initially, satisfaction declined more in high-risk than low-risk relationships. Process evidence was consistent with moderated mediation: In low-risk relationships only, being less trusting predicted higher levels of self-protective caution that forecast later declines in satisfaction.
