Approach versus avoidance: different types of commitment in intimate relationships.

The major objective of the present study was to examine whether approach versus avoidance commitment to one's intimate relationship was differentially predictive of relationship quality parameters in the long run. In the 1st testing period, 134 participants (67 romantic couples) answered questions about approach- versus avoidance-related measures. Commitment and relationship quality parameters such as satisfaction and emotions depending on the partner's presence were assessed in all 3 testing periods. The proposed distinction between an approach and an avoidance type of commitment was validated through correlations with other approach- versus avoidance-related measures. Longitudinal analyses revealed that approach commitment predicted relationship quality parameters positively, whereas avoidance commitment predicted them negatively. The results are discussed in terms of the benefit of an approach-avoidance-based conceptualization of commitment.
