The relationship between attachment orientation and the emotional and thematic content of autobiographical memory about marriage in later life was investigated. A total of 242 older married adults received a quick recall interview to retrieve as many events as one could of what happened in his or her marital life. Each event was rated by the participant on its emotional valence, and its thematic content was coded by two raters according to three themes: interaction mode of the couple, life domain, and interpersonal context. Results indicated that attachment security and attachment avoidance, but not attachment anxiety, predicted the emotional valence and relationship-relevant thematic contents (e.g., relationship-maintaining life domain and between-couple interpersonal context) of marital memories. Attachment by gender interactions revealed that men with lower avoidance retrieved more relationship-maintaining events, and women with higher anxiety or lower avoidance retrieved more between-couple events. Implications of results are discussed.
