Abstract: Antenatal depression is a known risk factor for postnatal depression both are common disorders associated with negative impacts on child development. Few studies have followed up women from pregnancy and through the postnatal period to explore how rates of depression change. This review evaluates recent evidence on depression during pregnancy and after childbirth. A search of Embase, PsychINFO, MEDLINE and Cochrane Reviews was carried out to identify longitudinal studies on antenatal and postnatal depression. Studies that measured depression during pregnancy and up to 1 year after childbirth were evaluated against a set of criteria (e.g. less than 50 % attrition). Of the initial 523 studies identified, 16 studies met the final inclusion criteria with a total of 35,419 women. The average rate of antenatal depression across these studies was 17 and 13 % postnatal depression. The longitudinal nature of the studies revealed that on average 39 % of those who experienced antenatal depression went on to have postnatal depression. Similarly, on average, 47 % of those with postnatal depression had also experienced antenatal depression. On average, almost 7 % of women reported significant depressive symptoms in pregnancy that persisted after childbirth. The review provided evidence that rates of depression tend to be higher during pregnancy than in the first year following childbirth. Furthermore, the longitudinal data show that there is much movement between the groups categorised as depressed or not depressed. There is evidence that postnatal depression is often a continuation of existing antenatal depression.

Abstract: The Strengths and Difficulties Questionnaire (SDQ) is a popular standardised instrument typically used for screening psychopathology in children and adolescents. However, peer reviewed studies evaluating the psychometric properties of the parent-rated preschool SDQ are lacking. The current study involved mothers of 5481 2 year olds (52 % male) from the Growing Up in New Zealand cohort, and investigated the psychometric properties of the preschool SDQ within this cohort. Confirmatory factor analysis was used to evaluate the SDQ's factor structure and test for measurement invariance of the factor model. Cronbach's alpha was used to measure the internal consistency of the subscales and total difficulties scale. We found support for a modified five-factor model, in which the prosocial factor was extended into a positive construal factor by allowing cross-loadings of reverse-scored items. Full measurement invariance was found across gender and socioeconomic status, and partial invariance was found across mother's ethnicity. Cronbach's alpha was satisfactory for all subscales (α range = 0.71-0.84), except peer problems (α = 0.54). Normative scores and bandings for normal, borderline and abnormal ranges are described for each subscale. Analyses revealed group differences in scores for child's gender, mother's ethnicity and socioeconomic status. Overall, satisfactory psychometric properties were found for the preschool SDQ in 2 year olds, indicating that that the questionnaire can be used in very young children.

Abstract: There is limited research on the preschool version of the Strengths and Difficulties Questionnaire (SDQ), and comparisons between mothers and fathers as informants and whether the factor structure shows measurement invariance across parents is lacking. Our study involved mothers ( n = 6,246) and fathers ( n = 3,759) of 2-year-old children from the Growing Up in New Zealand birth cohort. Confirmatory factor analysis was used to evaluate the factor structure of the SDQ and test for measurement invariance across mothers and fathers. For fathers, we found support for a modified five-factor model that accounts for a positive construal method effect. Internal consistency was good for measures except peer problems. Full measurement invariance of this modified model was found across mothers and fathers, and parents showed moderate agreement in their SDQ ratings (0.34 ≤ r ≤ 0.44). More research is needed on whether mother- and father-reports differ in sensitivity when screening for early childhood psychiatric disorders.

Abstract: High levels of alcohol exposure during pregnancy can damage developing brains and influence child behavior and learning. To examine the effects of lower levels of alcohol and very early exposure to alcohol on infant temperament and child behavior. The Growing Up in New Zealand study involves a prospective birth cohort of 6822 pregnant women of whom 6156 provided information on their child's temperament using the Infant Behavior Questionnaire-Revised (IBQ-R VSF) at 9 months and their child's behavior using the Strengths and Difficulties Questionnaire at 2 years. A series of adjusted linear regression models controlling for socio-demographic factors found alcohol consumption during pregnancy was most consistently related to Lower Positive Affect, Affiliation/Regulation, and Orienting Capacity temperament scores. Mothers who stopped drinking after becoming aware of their pregnancy, but had an unplanned pregnancy (hence may have a baby exposed to alcohol for longer), also reported infants with lower Orienting Capacity, Affiliation/Regulation, and Fear temperament scores compared to those that did not drink. Children whose mothers drank four or more drinks per week during pregnancy were more likely to report their child as having conduct problems, with higher total difficulties scores at age 2. Alcohol consumption during pregnancy has a negative effect especially on infant temperament, even if small amounts of alcohol are consumed. Our findings have implications for men and women who drink, medical professionals, and for the availability of contraception to those who drink, but do not plan to get pregnant.

Abstract: Depression during pregnancy has significant implications for pregnancy outcomes and maternal and child health. There is a need to identify which family, physical and mental health factors are associated with depression during pregnancy. An ethnically and socioeconomically erse s le of 5664 pregnant women living in New Zealand completed a face-to-face interview during the third trimester. Antenatal depression (AD) symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS). Maternal demographic, physical and mental health, and family and relationship characteristics were measured. The association between symptoms of AD and maternal characteristics was determined using multiple logistic regression. 11.9% of the participating women had EPDS scores (13+) that indicated probable AD. When considering sociodemographic predictors of AD symptoms, we found that women from non-European ethnicities, specifically Pacific Islander, Asian and other, were more likely to suffer from AD symptoms. Greater perceived stress during pregnancy and a diagnosis of anxiety both before and during pregnancy were also associated with greater odds of having AD according to the EPDS. The women were in their third trimester of pregnancy at the interview. Therefore, we cannot discount the possibility of recall bias for questions relating to pre-pregnancy status or early-pregnancy behaviours. AD is prevalent amongst New Zealand women. Ethnicity, perceived stress and anxiety are particularly associated with a greater likelihood of depression during pregnancy. Further attention to supporting maternal mental health status in the antenatal period is required.

Abstract: Objectives Antenatal and postnatal depression can lead to poor outcomes for women and their children. The aim of this study was to explore whether risk factors differ for depression symptoms that are present during pregnancy and/or after childbirth. Methods An ethnically and socioeconomically erse s le of 5301 women completed interviews during the third trimester of pregnancy and 9 months after childbirth. Depression symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS). Depression symptoms (defined as EPDS >12) among participants and associations with pre-pregnancy and pregnancy maternal characteristics were explored using logistic regression. Results The rate of antenatal depression symptoms (ADS) only was 8.5, 5% of women had depression symptoms at 9 months postpartum (PDS) only and 3% experienced depression symptoms at both time points. Perceived stress and Pacific or Asian ethnicity were risk factors for ADS and PDS. Anxiety during and before pregnancy was a risk factor for ADS only while having a pre-pregnancy diagnosis of depression was a risk factor for PDS only. Having ADS increased the odds ratio of PDS by 1.5 (95% CI 1.01-2.30). Conclusions The results supported evidence from previous longitudinal studies that depression symptoms appear to be higher during pregnancy than in the first year following childbirth. The study found that PDS may often be a continuation or recurrence of ADS.
