Assessment of mother - baby interaction: Portuguese version of Interaction Rating scales

As Escalas de Avaliação da Interação Mãe-Bebé constituem a versão portuguesa das Interaction Rating Scales, propostas por Field (1980), e têm por objetivo avaliar a interação mãe-bebé, aos 3 meses de idade do bebé. As Escalas de Avaliação da Interação Mãe-Bebé foram administradas a 51 díades mãe-bebé aos 3, 6 e 12 meses pós-parto. A versão portuguesa das escalas mostrou elevados índices de consistência interna – Alfa de Cronbach 0,85 (IRSff bebé), 0,91 (IRSff mãe), 0,87 (IRSal bebé), 0,82 (IRSal mãe), assim como elevada fidelidade e validade concorrente e preditiva. As Escalas de Avaliação da Interação Mãe-Bebé assume-se, assim, como um instrumento robusto na avaliação da interação mãe-bebé, na situação de interação face-a-face e na situação de interação alimentar, podendo ser utilizadas em diferentes amostras e contextos, clínicos e de investigação.The Escalas de Avaliação da Interação Mãe-Bebé are a portuguese version of the Interaction Rating Scales proposed by Field (1980); aim to evaluate the motherinfant interaction at infant’s 3 months old. The translated version was administered to 51 mother-infant dyads at 3, 6, and 12 months postpartum. The Portuguese version showed high levels of internal consistency – Cronbach’s Alpha .85 (IRSface-to-face infant), .91 (IRS face-to-face mother), .87 (IRSfeeding infant), .82 (IRSfeeding mother) – concurrent and predictive validity and reliability. The Escalas de Avaliação da Interação Mãe-Bebé are an important instrument on the evaluation of mother-infant interaction and it could be used with different samples and in clinical and research contexts.PTDC/SAU/SAP/116738/201

Mother's prenatal and postpartum depression symptoms and infant's sleep problems at 6 months

Mother's prenatal and postpartum depression have been associated with infant's sleep problems. This study aimed to analyze (a) the effects of mother's prenatal and postpartum depression symptoms, including the effects of prenatal and postpartum anxiety and depression scores of the Edinburgh Postnatal Depression Scale (EPDS), on infant's sleep problems at 6 months, and (b) the interaction effect between mother's prenatal and postpartum depression symptoms and infant's sex on infant's sleep problems at 6 months. The sample was comprised of 164 mother-infant dyads whose mothers completed measures of depression at the third trimester of pregnancy, 2 weeks, 3 and 6 months postpartum and a measure of infant's sleep problems at 6 months (CSHQ-I). Mother's prenatal depression symptoms, specifically depression scores of the EPDS, predicted more infant's sleep anxiety and daytime sleepiness, while mother's depression symptoms at 2 weeks postpartum, specifically anxiety scores of the EPDS, predicted more bedtime resistance and CSHQ-I total scores at 6 months. Boys of mothers with more prenatal depression symptoms presented more sleep anxiety at 6 months. Both mother's prenatal and early postpartum depression symptoms have a negative effect on the emergence of infant's sleep problems. Additionally, boys seem more vulnerable to mother's prenatal depression symptoms.This study was conducted at Psychology Research Centre (UID/PSI/01662/2013), University of Minho, and supported by the Portuguese Foundation for Science and Technology and the Portuguese Ministry of Education and Science through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement, under the Grant No. POCI-01-0145-FEDER007653.

Maternal adjustment and maternal attitudes in adolescent and adult pregnant women

Study Objective: This study analyzes differences between adolescent and adult pregnant women and the contribution of maternal age to maternal adjustment and maternal attitudes during pregnancy. Design, Setting, and Participants: A sample of 398 Portuguese pregnant women (111 younger than 19 years) was recruited in a Portuguese Maternity Hospital and completed the Maternal Adjustment and Maternal Attitudes Questionnaire between the 24th and 36th weeks of gestation. Main Outcome Measures: Maternal Adjustment and Maternal Attitudes Questionnaire. Results: Adolescent pregnant women show lower maternal adjustment (poorer body image and worse marital relationship) and poorer maternal attitudes (more negative attitudes to sex) than adult pregnant women. When controlling for socio-demographics, age at pregnancy predicts poorer body image and more negative attitudes to sex, but not a worse marital relationship, more somatic symptoms or negative attitudes to pregnancy and the baby. A worse marital relationship was better predicted by living without the partner, and more somatic symptoms and negative attitudes to pregnancy and the baby was predicted by higher education. Conclusion: Adolescent pregnant women show lower maternal adjustment and poorer maternal attitudes than adult pregnant women according to socio-demographics and unfavorable developmental circumstances.This research was supported by FEDER Funds through the COMPETE (Programa Operacional Factores de Competitividade) and by National Funds through FCT (Fundacão para a Ciência e a Tecnologia) under the project PTDC/SAU/SAP/116738/2010

Maternal prenatal depressive symptoms and infant sleep problems: the role of infant temperament and sex

Published online: 19 Dec 2022Objectives: We aimed to analyze whether (1) infant temperament mediates the impact of maternal prenatal depressive symptoms on infant sleep problems and (2) the mediation role of infant temperament was moderated by the infant’s sex. Methods: The sample was comprised of 172 mother-infant dyads. Mothers completed self-reported measures of prenatal and postnatal depressive symptoms, infant temperament (negative affectivity, surgency/extraversion, and orienting regulation), and sleep problems. Results: While controlling for maternal postnatal depressive symptoms, our results revealed that (1) infant negative affectivity at two weeks partially mediated the impact of maternal prenatal depressive symptoms on sleep anxiety at six months, and (2) this mediation is independent of the infant’s sex. Conclusions: Our findings provided evidence that negative affectivity can be an early specific marker of sleep anxiety and can partially explain the negative impact of maternal prenatal depressive symptoms on further sleep problems in the infant.This work was supported by the Fundação para a Ciência e a Tecnologia [PTDC/SAU/SAP/116738/2010,SFRH/BD/113005/2015,SFRH/BD/115048/2016]

Exclusive breastfeeding at three months and infant sleep-wake behaviors at two weeks, three and six months

This study assessed infant sleep-wake behavior at two weeks, three and six months as function of feeding method at three months (exclusively breastfed, partially breastfed, and exclusively formula fed infants). Mothers of 163 first-born, full-term, normal birth weight, healthy infants completed socio-demographic, depression, anxiety, and infant sleep-wake behavior measures. No effects were found for sleep arrangements, depression or anxiety, on feeding methods and sleep-wake behavior at three months. At two weeks exclusively breastfed infants at three months spent more hours sleeping and less hours awake during the 24-h period than partially breastfed infants. At three months, exclusively breastfed infants had a shorter of the longest sleep period at night than exclusively formula fed infants. At six months, exclusively breastfed infants at three months spent more hours awake at night than partially breastfed infants, awake more at night than exclusively formula fed infants, and had a shorter sleep period at night than partially breastfed and exclusively formula fed infants. This study showed differences in sleep-wake behaviors at two weeks, three and six months, when exclusively breastfed infants are compared with partially breastfed and exclusively formula fed infants at three months, while no effects were found for sleep arrangements, depression or anxiety.PTDC/SAU/SAP/116738/2010; SFRH/BSAB/14445/2014; POCI-01-0145-FEDER-007653info:eu-repo/semantics/publishedVersio

Infant sleep-wake behaviors at two weeks, three and six months

Although infant sleep-wake behavior presents several developmental changes during the first six months, literature lacks on reference values and few studies have explored the role of individual change and stability on infant sleep-wake behavior during the first six months. This study aimed (1) to describe infant sleep-wake behaviors during the 24-h period, day and night, at two weeks, three, and six months, (2) and to explore developmental changes and the role of individual change and stability on infant sleep-wake behaviors from two weeks to six months. Ninety-four primiparous mothers completed measures on infant sleep-wake behaviors at two weeks, three and six months. Significant developmental changes were found on infant sleep-wake behaviors from two weeks to six months. Twoweek- old infants sleep 13.3 h, spend 8.7 h awake, awake 6.1 times, have 0.4 h of latency to sleep, and 3.2 h of longest sleep period. Three-month-old infants sleep 13.0 h, spend 9.2 h awake, awake 5.5 times, have 0.4 h of latency to sleep, and 5.2 h of longest sleep period. Sixmonth- old infants sleep 12.2 h, spend 10.0 h awake, awake 5.2 times, have 0.4 h of latency to sleep, and 5.6 h of longest sleep period. Significant individual change and stability were also found on infant sleep-wake behaviors from two weeks to six months. Despite significant developmental and individual changes, individual stability explains a significant amount of the variance on infant sleep-wake behaviors over the first six months of life.FEDER Funds through the Programa Operacional Factores de Competitividade − COMPETE and by National Funds through FCT − Fundação para a Ciência e a Tecnologia under the project: PTDC/SAU/SAP/116738/2010 and SFRH/BSAB/14445/2014 grantPortuguese Foundation for Science and Technology and the Portuguese Ministry of Education and Science through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement (POCI-01-0145- FEDER-007653)Psychology Research Centre (UID/PSI/01662/2013), University of Minh

Karitane parenting confidence scale: measuring parenting self-efficacy in Portuguese mothers during the first year postpartum

Background: The Karitane Parenting Confidence Scale (KPCS) was designed to assess parenting self-efficacy in parents of infants during the first year. Objective: The aim of this study was to analyse the psychometric characteristics of the KPCS in Portuguese mothers during the firstyear postpartum. Methods: A sample of 383 mothers were recruited at two public outpatient units in Northern Portugal. Mothers completed the KPCS, a sociodemographic questionnaire, and measures of depressive and anxiety symptoms at least one time between two weeks, three, six and 12 months postpartum. Results: Good fit was found for a factor model with three subscales: parenting, support and child development. The KPCS presented good internal consistency. Regarding the criterion validity of the KPCS, significant effects of mother’s age were found on the development subscale and significant associations were found between mother’s depressive and anxiety symptoms and the KPCS total scale and subscales. Optimal clinical cut-offs were suggested. Conclusion: Findings provided evidence on the psychometric characteristics of the KPCS which can be used to assess parenting selfefficacy in Portuguese mothers during the first-year postpartum, possibly identifying mothers with low parenting self-efficacy.This study was conducted at the Psychology Research Centre (PSI/01662), School of Psychology, University of Minho, and supported by the Foundation for Science and Technology.

Sleep-wake behaviour during the first 12 months of life and associated factors: a systematic review

This paper aims to provide a systematic review of the literature on the associated factors with infant sleep-wake behaviour during the first 12 months of life, namely (1) the factors positively and negatively associated with sleep-wake behaviour and (2) the factors positively and negatively affected by sleep-wake behaviour. This systematic review was based on a standard protocol constructed according with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement and included 146 papers. Two typologies of factors were found in the literature: factors positively and negatively associated with infant sleep-wake behaviour and effects of sleep-wake behaviour. Different factors were identified as being positively and negatively associated with the different sleep-wake behaviours and positively and negatively affected by the different sleep-wake behaviours during the first 12 months of life. Some inconsistent results could be explained by methodological differences between the studies.This work was supported by FEDER Funds through the Programa Operacional Factores de Competitividade – COMPETE and by National Funds through FCT – Fundação para a Ciência e a Tecnologia under the project: PTDC/SAU/SAP/116738/ 2010 and SFRH/BD/113005/2015 PhD grant.

The breastfeeding self-efficacy scale-short form: psychometric characteristics in portuguese pregnant women

The Breastfeeding Self-Efficacy Scale-Short Form is a reliable instrument to measure mother's confidence in her ability to breastfeed. The Breastfeeding Self-Efficacy Scale-Short Form has traditionally been used postnatally, but evidence suggests that it can be used antenatally to identify mothers at-risk of requiring additional support to improve breastfeeding outcomes.This research was supported by FEDER Funds through the Programa Operacional Factores de Competitividade−COMPETE and by National Funds through FCT−Fundação para a Ciência e a Tecnologia under the project: PTDC/SAU/SAP/116738/2010.
