OBJECTIVE : In recent years, the role of social support on different aspects of health especially pregnancy and childbirth has been emphasized. Social support facilitates individual access to necessary resources during stressful periods of life like pregnancy and childbirth. Present evidence of effects of social support on birth experience is inconsistent, Therefore, this study aimed to determine the correlation between perceived social support in pregnant women and their childbirth experience. METHODS : Analytic-cross sectional survey. METHODS : Al-Zahra maternity hospital in Rasht, Iran. METHODS : 185 pregnant women who were in latent phase of labor entered the study and finally, 89.18% (n = 165) completed the study. METHODS : To measure perceived social support, the Multidimensional Scale of Perceived Social Support was used at latent phase of labor and to measure childbirth experience, the Childbirth Experience Questionnaire was used within 2 h after childbirth until the mother was discharged. RESULTS : Mean score of perceived social support by significant others (4.18 ± 0.79) was higher than other dimensions of social support. Total mean score of childbirth experience was 58.13 ± 10.72 (score range: 22-88). Logistic regression results showed that support by significant others (P = 0.042, OR = 1.56), gestational age (P = 0.003, OR = 1.56) and mode of delivery (P = 0.004, OR = 0.33) are predictor variables of childbirth experience. CONCLUSIONS : Perceived social support by significant others (spouse) during pregnancy has an important effect on woman`s childbirth experience. Therefore, providing training programs for family especially for spouse in order to increase maternal support during pregnancy is recommended, which can lead to a positive childbirth experience.
