Pregnancy-specific coping and changes in emotional distress from mid- to late pregnancy.

Objective: To examine whether pregnancy-specific coping predicts changes in emotional distress from mid- to late pregnancy. Background: There is a need to identify ways of coping that reduce or elevate emotional distress in pregnant women as such distress increases the risk of adverse birth outcomes. Methods: 132 women receiving prenatal care from a university hospital midwifery practice were recruited prior to 25 weeks gestation (M = 19.58, SD = 5.14). The state anxiety version of the State-Trait Personality Inventory (STPI) and the Revised Prenatal Distress Questionnaire (NuPDQ) were administered in mid- (M = 25.7 weeks, SD = 4.55) and late (M = 33.4 weeks, SD = 4.18) pregnancy and the Revised Prenatal Coping Inventory (NuPCI) at the latter timepoint. Results: Factor analysis of the NuPCI identified five distinct, conceptually interpretable types of coping: Prayer/Spirituality, Receiving Social Support, Planning/Preparation, Positive Appraisal, and Avoidant Coping. Avoidant Coping was used least frequently and Positive Appraisal was used most. The STPI and NuPDQ were aggregated to create a measure of emotional distress. After controlling for mid-pregnancy distress, Avoidant Coping predicted greater emotional distress in late pregnancy (ß = .18, R2 = .61, p < .01) and Positive Appraisal predicted lower late pregnancy distress (ß = -.15, R2 = .60, p < .01). Conclusion: This is one of the first studies to demonstrate that specific ways of coping with stress during pregnancy predict changes in pregnant women's emotional distress. The NuPCI is a psychometrically sound self-report instrument to examine coping and its association with emotional distress.

Psychometric properties of the Prenatal Health Behavior Scale in mid- and late pregnancy.

INTRODUCTION: Psychometrically sound self-report measures are important tools to advance research on health behaviors in pregnancy. The Prenatal Health Behavior Scale (PHBS) has been used in prior studies to quantify health behaviors and examine their associations with relevant variables, but its psychometric properties have not been carefully investigated. METHODS: In a sample of low-risk women, we examined the factor structure, reliability, and validity of the PHBS at mid- (N = 138) and late (N = 102) pregnancy. RESULTS: In confirmatory factor analysis, items on the PHBS loaded onto a single reliable factor, but separating health-promoting and health-impairing behavior into two factors had better model fit. The scales defined by these two factors had good internal consistency in mid- and late pregnancy, were only moderately correlated, and were predicted by somewhat different sets of sociodemographic and psychological variables. Pregnancy-specific stress was a robust predictor of health-promoting and health-impairing behavior across time. DISCUSSION: Results bolster confidence in the reliability and validity of the PHBS and its appropriateness as a self-report tool for investigation of health behaviors among pregnant women. This study is one of the first investigations to examine patterns and predictors of health behavior practices at two time periods of pregnancy.
