Background: Childcare stress has been shown to predict postpartum depression; however, there is little research exploring and validating the dimensions of childcare stress instruments such that preventive interventions can be created., Objectives: The aim of this study was to develop and psychometrically test an instrument to measure parental perceptions of postpartum childcare stress., Methods: Using research based on postpartum stress and childcare stress, the Postpartum Childcare Stress Checklist (PCSC) was developed, and content validity was judged by experts. The PCSC was psychometrically assessed in a cohort of 541 women in a health region near Vancouver, Canada, who were followed to 8 weeks postpartum in 2002. The psychometric assessment analyses comprised internal consistency, exploratory factory analysis, concurrent validity, and predictive validity., Results: The 19-item PCSC had good internal consistency (Kuder-Richardson Formula 20 coefficient: 0.81). Exploratory factor analysis revealed the following dimensions: (a) relationship with the partner, (b) caring for the infant, (c) maternal social interactions, and (d) establishing a new routine. Predictive validity analyses showed that PCSC total and subscale scores at 4 weeks were positively correlated with depressive symptomatology, anxiety, and perceived stress and negatively correlated with global and partner support at 8 weeks postpartum., Discussion: The PCSC is a measure of childcare stress with excellent reliability and validity. Upon further testing, it may be used to identify women and couples in need of greater support, individualize postpartum care, and evaluate the effectiveness of preventive interventions.

The objective of this study was to determine the contribution of interpersonal violence and substance use to the prediction of postpartum depressive symptomatology. A community-based sample of 634 women in British Columbia, Canada was screened for interpersonal violence and substance use using the Antenatal Psychosocial Health Assessment (ALPHA) form. Of these women, 497 (78%) subsequently completed questionnaires at 8 weeks postpartum to assess for depressive symptomatology using the Edinburgh Postnatal Depression Scale (EPDS). A predictive model for postpartum depressive symptomatology (EPDS > 9) was developed using regression analysis. Findings suggest that women who experience past or current interpersonal violence or personal or partner substance use problems should be considered for targeted screening for postpartum depression (PPD).

Background: A lack of social support has consistently been demonstrated to be an important modifiable risk factor for postpartum depression. As such, a greater understanding of specific support variables may assist health professionals in the development of effective preventive interventions. The purpose of this paper was two-fold: (1) to determine if women discriminated between global and relationship-specific perceptions of support, and (2) to examine the influence of global and relationship-specific perceptions of support in the immediate postpartum period on the development of depressive symptomatology at 8 weeks postpartum., Methods: As part of a longitudinal study, a diverse sample of 594 mothers completed questionnaires that included the Edinburgh Postnatal Depression Scale (EPDS) and global and relationship-specific (e.g., partner, mother, and other women with children) measures of support., Results: Mothers clearly discriminated between global and relationship-specific perceptions of support and those with depressive symptomatology at 8 weeks had significantly lower perceptions of both global and relationship-specific support at 1-week postpartum. Using discriminant function analysis, four variables, reliable reliance from partner, nurturance from partner, attachment to other women with children, and EPDS score at 1-week postpartum, differentiated between mothers who experienced depressive symptomatology at 8 weeks and those who did not., Conclusion: Relationship-specific interventions may be beneficial if they include strategies that target a positive partner relationship through preceptions of reliable alliance and feeling needed and provide opportunites for interaction with other mothers. Maternal mood at 1 week postpartum was the largest predictor of depressive symptomatology at 8 weeks.

Researchers have found evidence that breastfeeding self-efficacy is an important variable that significantly influences initiation and duration rates. The purpose of this study was to develop a multi-factorial predictive model of breastfeeding self-efficacy in the first week postpartum. As part of a longitudinal study, a population-based sample of 522 breastfeeding mothers in a health region near Vancouver, British Columbia completed mailed questionnaires at 1-week postpartum. Bivariate correlations were used to select variables for the multiple regression analysis. The best-fit regression model revealed eight variables that explained 54% of the variance in Breastfeeding Self Efficacy Scale (BSES) scores at 1-week postpartum: maternal education, support from other women with children, type of delivery, satisfaction with labor pain relief, satisfaction with postpartum care, perceptions of breastfeeding progress, infant feeding method as planned, and maternal anxiety. The BSES may be used to identify risk factors, enabling health professionals to improve quality of care for new breastfeeding mothers., (Copyright 2006 Wiley Periodicals, Inc.)

This paper describes the development and psychometric assessment of a scale to measure satisfaction with intrapartum and postpartum care in hospital: The Care in Obstetrics: A Measure For Testing Satisfaction (COMFORTS) scale. A sample of 415 participants completed the 40-item scale. Cronbach's alpha for the scale was .95. Evaluation of construct validity through principal components factor analysis with varimax rotation yielded six subscales: confidence in newborn care, postpartum nursing care, provision of choice, the physical environment, respect for privacy, and labor/delivery nursing care. The COMFORTS scale was able to discriminate between multiparous versus primiparous women, and between women cared for in single room maternity care versus in separate labor/delivery and postpartum rooms. Pending further validation, the COMFORTS scale has potential to measure women's satisfaction with childbirth care and contribute to an assessment of the quality of care provided., (Copyright 2006 Wiley Periodicals, Inc.)

Background: Postpartum depression is a serious condition for women after childbirth. Although its etiology is unclear, one potentially important predictive variable that has received little attention is maternal sleep deprivation. The objective of this study was to examine relationships among infant sleep patterns, maternal fatigue, and the development of postpartum depression in women with no major depressive symptomatology at 1 week postpartum., Methods: As part of a population-based postpartum depression study, 505 women who had an Edinburgh Postnatal Depression Scale (EPDS) score < 13 at 1 week postpartum completed questionnaires at 4 and 8 weeks postpartum., Results: Mothers exhibiting major depressive symptomatology (EPDS > 12) at 4 and 8 weeks were significantly more likely to report that their baby cried often, be woken up 3 times or more between 10 pm and 6 am, have received less than 6 hours of sleep in a 24-hour period over the past week, indicate that their baby did not sleep well, and think that their baby's sleep pattern did not allow them to get a reasonable amount of sleep. Consistent with these findings, mothers with an EPDS score > 12 were significantly more likely to respond that they often felt tired., Conclusions: These results suggest that infant sleep patterns and maternal fatigue are strongly associated with a new onset of depressive symptoms in the postpartum period, and provide support for the development of postpartum depression preventive interventions designed to reduce sleep deprivation in the early weeks postpartum.

Objective: The purpose of this study was to reduce the number of items on the original Breastfeeding Self-Efficacy Scale (BSES) and psychometrically assess the revised BSES-Short Form (BSES-SF)., Design: As part of a longitudinal study, participants completed mailed questionnaires at 1, 4, and 8 weeks postpartum., Setting: Health region in British Columbia., Participants: A population-based sample of 491 breastfeeding mothers., Main Outcome Measures: BSES, Edinburgh Postnatal Depression Scale, Rosenberg Self-Esteem Scale, and Perceived Stress Scale., Results: Internal consistency statistics with the original BSES suggested item redundancy. As such, 18 items were deleted, using explicit reduction criteria. Based on the encouraging reliability analysis of the new 14-item BSES-SF, construct validity was assessed using principal components factor analysis, comparison of contrasted groups, and correlations with measures of similar constructs. Support for predictive validity was demonstrated through significant mean differences between breastfeeding and bottle feeding mothers at 4 (p < .001) and 8 (p < .001) weeks postpartum. Demographic response patterns suggested the BSES-SF is a unique tool to identify mothers at risk of prematurely discontinuing breastfeeding., Conclusions: These psychometric results indicate the BSES-SF is an excellent measure of breastfeeding self-efficacy and considered ready for clinical use to (a) identify breastfeeding mothers at high risk, (b) assess breastfeeding behaviors and cognitions to individualize confidence-building strategies, and (c) evaluate the effectiveness of various interventions and guide program development.
