Objective: The aim of this study was to investigate the relationship of depression, anxiety, somatization symptoms, attachment dimensions and resilience with infertilitiy related stress. Our second aim was to explore the associations of In Vitro Fertilisation (IVF) treatment outcome with attachment dimensions, resilience, infertility related stress, depression, anxiety, and somatization symptoms. Method: 88 women who were consecutively applied to the Kocaeli University Medical Faculty Department of Gynecology and Obstetric, Assisted Reproductive Techniques Center and found eligible for IVF treatment were inclu-ded in the study. Sociodemographic data form, depression, anxiety and somatization subscales of Brief Symptom Inventory (BSI), Experiences in Close Relationships Scale (ECR), The Resilience in Midlife Scale (RIM) and Fertility Problem Inventory (FPI) were administered to all participants before IVF treatment protocol. Participants were evaluated whether pregnancy occurred or not 3 months after the IVF treatment protocol was applied. Results: A significant positive correlation was found between the FSE total score and the ECR anxiety (p<0.001, r=0.314) and ECR avoidance (p<0.001, r=0.364) scores. A negative correlation was found also between the FSE total score and RIM total score (p<0.001, r=-0.434). It was found that BSI anxiety, depression and somatization scores, ECR anxiety and avoidance scores, RIM total and sub scale scores and FSE total score averages did not differ according to IVF treatment outcome. Discussion: The results of our study showed that the anxiety and avoidance dimensions of attachment and resilience are related to infertility stress. Anxiety, depression, somatization, infertility related stress, attachment and resilience scores were not associated with IVF treatment outcome. Psychosocial interventions to strengthen resilience and attachment based therapeutic approaches may help to reduce infertility related stress.
