Validation of the Persian version of the Daily Spiritual Experiences Scale (DSES) in Pregnant Women: A Proper Tool to Assess Spirituality Related to Mental Health.

Abstract

Assessing spirituality in healthy pregnant women may lead to supportive interventions that will improve their care. A psychometrically valid measure such as the Daily Spiritual Experiences Scale (DSES) may be helpful in this regard. The current study sought to adapt a Persian version of DSES for use in pregnancy. A total of 377 pregnant women were recruited from three general hospitals located in Tehran, Iran. Administered scales were the DSES, Duke University Religion Index, Santa Clara Strength of Religious Faith scale, and Depression Anxiety Stress Scale, as well as demographic measures. Reliability of the DSES was tested using Cronbach's alpha for internal consistency and the intraclass correlation coefficient (ICC) for test-retest stability. Scale validity was assessed by criterion-related tests, known-groups comparison, and exploratory factor analysis. Participant's mean age was 27.7 (4.1), and most were nulliparous (70%). The correlation coefficient between individual items on the scale and the total score was greater than 0.30 in most cases. Cronbach's alpha for the scale was 0.90. The ICC for 2-week test-retest reliability was high (0.86). Relationships between similar and dissimilar scales indicated acceptable convergent and divergent validity. The factor structure of the scale indicated a single factor that explained 59% of the variance. The DSES was found to be a reliable and valid measure of spirituality in pregnant Iranian women. This scale may be used to examine the relationship between spirituality and health outcomes, research that may lead to supportive interventions in this population.
