Data were acquired from a total of 422 university students with 216 female and 206 male students via Couple Attachment Scale, Stress Coping Styles Scale and Coopersmith Self-Esteem Inventory. Positive and statistically significant relationships were determined between self-confident approach, optimistic approach and social support approach sub-scales as a result of Pearson Product Moments Correlation Coefficient analysis; whereas a negative and statistically significant relationship was determined between helpless approach and submissive approach sub-scales and self-esteem. It was determined as a result of the One Way MANOVA analysis that couples with secure and insecure attachment differ with regard to ways of coping with stress and self-esteem levels and that couples with secure attachment make use of self-confident approach, optimistic approach and social support approach from among styles of coping with stress, whereas couples with insecure attachment use helpless approach and submissive approach styles and that they have lower self-esteem levels.
