Smoking cessation in pregnant women: A randomized controlled trial investigating the effectiveness of an eHealth intervention including heart rate variability-biofeedback training

BACKGROUND

Prenatal smoking and stress are associated with adverse health effects for women themselves and are risk factors for adverse outcomes of the child. Effective interventions are needed to support women with smoking cessation and reducing stress. The aims were (1) to test the effectiveness of an 8-week eHealth intervention targeting stress reduction and smoking cessation; (2) to examine whether stress reduction mediated the intervention effect on smoking behavior; (3) to test motivation to quit as a moderator; and (4) to investigate a dose-response effect of program usage.

METHODS

Pregnant women were included if they were >18 years of age, < 28 weeks pregnant at recruitment, and currently smoking. In total, 156 consenting participants were randomly assigned to the intervention or active control condition. Study outcomes on smoking (yes/no, frequency, and quantity) were collected via online questionnaires at pre-intervention (baseline; t0), post-intervention (8 weeks after t0; t1), and follow up at two weeks (t2) and three months (t3) after birth.

RESULTS

Smoking and stress reduced over the 8-week period in both conditions. The intervention effect on smoking was not mediated by stress reduction. Motivation to quit was found to moderate the intervention effect (smoking frequency and quantity) and a dose-response effect was found for program usage in the intervention for the reduction on smoking frequency and quantity.

CONCLUSION

Program usage and motivation to quit are important for smoking reduction in pregnant women. Further research is needed to examine how the intervention could be improved to increase treatment effectiveness.

Traumatic birth and childbirth-related post-traumatic stress disorder: International expert consensus recommendations for practice, policy, and research

BACKGROUND

Research suggests 1 in 3 births are experienced as psychologically traumatic and about 4% of women and 1% of their partners develop post-traumatic stress disorder (PTSD) as a result.

AIM

To provide expert consensus recommendations for practice, policy, and research and theory.

METHOD

Two consultations (n = 65 and n = 43) with an international group of expert researchers and clinicians from 33 countries involved in COST Action CA18211; three meetings with CA18211 group leaders and stakeholders; followed by review and feedback from people with lived experience and CA18211 members (n = 238).

FINDINGS

Recommendations for practice include that care for women and birth partners must be given in ways that minimise negative birth experiences. This includes respecting women's rights before, during, and after childbirth; and preventing maltreatment and obstetric violence. Principles of trauma-informed care need to be integrated across maternity settings. Recommendations for policy include that national and international guidelines are needed to increase awareness of perinatal mental health problems, including traumatic birth and childbirth-related PTSD, and outline evidence-based, practical strategies for detection, prevention, and treatment. Recommendations for research and theory include that birth needs to be understood through a neuro-biopsychosocial framework. Longitudinal studies with representative and global samples are warranted; and research on prevention, intervention and cost to society is essential.

CONCLUSION

Implementation of these recommendations could potentially reduce traumatic births and childbirth-related PTSD worldwide and improve outcomes for women and families. Recommendations should ideally be incorporated into a comprehensive, holistic approach to mental health support for all involved in the childbirth process.

Testing reliability and validity of practitioner-rated parental sensitivity: A novel tool for practice

Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e-learning tool and an interactive decision tree provided through a mobile application, called the OK! package. Independent raters assessed parental sensitivity using the OK! package (N = 11 raters) and the NICHD Parental Sensitivity rating scales (N = 22 raters) on the basis of videotaped mother-child interactions at 10- or 12-months-old (N = 294) and at 24-months-old (N = 204) from the Dutch longitudinal cohort study Generation2 . Mothers reported on children's externalizing and internalizing problems and social competence when children were 4 and 7 years old. Results showed excellent single interrater reliability for raters using the OK! package (mean ICC = .79), and strong evidence for convergent validity at 10- or 12-month-old (r = .57) and 24-month-old (r = .65). Prospective associations of neither parental sensitivity rated using the OK! package or the NICHD Parental Sensitivity rating scales with child developmental outcomes were statistically significant (p > .05), with overlapping 95% confidence intervals for both measures. The OK! package provides a promising direction for testing alternatives to current training and instruction modalities.

Attachment relationship quality with mothers and fathers and child temperament: An individual participant data meta-analysis

A growing body of research suggests that, compared with single parent-child attachment relationships, child developmental outcomes may be better understood by examining the configurations of child-mother and child-father attachment relationships (i.e., attachment networks). Moreover, some studies have demonstrated an above-chance level chance of concordance between the quality of child-mother and child-father attachment relationships, and child temperament has been offered as a plausible explanation for such concordance. To assess whether temperament plays a role in the development of different attachment network configurations, in this preregistered individual participant data meta-analysis we tested the degree to which the temperament dimension of negative emotionality predicts the number of secure, insecure-avoidant, insecure-resistant, and disorganized attachment relationships a child has with mother and father. Data included in the linear mixed effects analyses were collected from seven studies sampling 872 children (49% female; 83% White). Negative emotionality significantly predicted the number of secure (d = -0.12) and insecure-resistant (d = 0.11), but not insecure-avoidant (d = 0.04) or disorganized (d = 0.08) attachment relationships. Nonpreregistered exploratory analyses indicated higher negative emotionality in children with insecure-resistant attachment relationships with both parents compared to those with one or none (d = 0.19), suggesting that temperament plays a small yet significant role in child-mother/child-father insecure-resistant attachment relationships concordance. Taken together, results from this study prompt a more in-depth examination of the mechanism underlying the small yet significantly higher chance that children with increased negative emotionality have for developing multiple insecure-resistant attachment relationships.

Configurations of mother-child and father-child attachment relationships as predictors of child language competence: An individual participant data meta-analysis

An individual participant data meta-analysis was conducted to test pre-registered hypotheses about how the configuration of attachment relationships to mothers and fathers predicts children's language competence. Data from seven studies (published between 1985 and 2014) including 719 children (Mage : 19.84 months; 51% female; 87% White) were included in the linear mixed effects analyses. Mean language competence scores exceeded the population average across children with different attachment configurations. Children with two secure attachment relationships had higher language competence scores compared to those with one or no secure attachment relationships (d = .26). Children with two organized attachment relationships had higher language competence scores compared to those with one organized attachment relationship (d = .23), and this difference was observed in older versus younger children in exploratory analyses. Mother-child and father-child attachment quality did not differentially predict language competence, supporting the comparable importance of attachment to both parents in predicting developmental outcomes.

Development of a resilience-enhancing intervention during and after pregnancy: a systematic process informed by the behaviour change wheel framework

BACKGROUND

Pregnancy and the transition to parenthood are accompanied by multiple changes and stress exposure. Resilience has the potential to counteract the negative impact of stress and can be a protective factor against mental health problems. To date, the use of a theoretical framework in the development or application of resilience interventions during pregnancy up to one year postpartum is missing. The aim of this study is to develop an intervention to enhance resilience for pregnant women up to one year postpartum.

METHODS

A systematic and theory-based approach informed by the Behaviour Change Wheel framework and the theoretical model of perinatal resilience was applied. The development took place in three phases and during the process, the target group, researchers and clinicians were involved.

RESULTS

A combination of resilience-enhancing exercises, group sessions and an online support platform, including follow-up at six and twelve months after delivery, was designed to enhance resilience during pregnancy and up to one year postpartum. This intervention incorporates 5 intervention functions delivered by 18 behaviour change techniques.

CONCLUSIONS

This study responds to the need for theory-based intervention programs aiming to enhance resilience to improve the psychological health of pregnant women. We developed a multicomponent resilience-enhancing intervention for pregnant women up to one year postpartum.

Validation of Photoplethysmography Using a Mobile Phone Application for the Assessment of Heart Rate Variability in the Context of Heart Rate Variability-Biofeedback

OBJECTIVE

Heart rate variability-biofeedback (HRV-BF) is an effective intervention to reduce stress and anxiety and requires accurate measures of real-time HRV. HRV can be measured through photoplethysmography (PPG) using the camera of a mobile phone. No studies have directly compared HRV-BF supported through PPG against classical electrocardiogram (ECG). The current study aimed to validate PPG HRV measurements during HRV-BF against ECG.

METHODS

Fifty-seven healthy participants (70% women) with a mean (standard deviation) age of 26.70 (9.86) years received HRV-BF in the laboratory. Participants filled out questionnaires and performed five times a 5-minute diaphragmatic breathing exercise at different paces (range, ~6.5 to ~4.5 breaths/min). Four HRV indices obtained through PPG, using the Happitech software development kit, and ECG, using the validated NeXus apparatus, were calculated and compared: RMSSD, pNN50, LFpower, and HFpower. Resonance frequency (i.e., optimal breathing pace) was also compared between methods.

RESULTS

All intraclass correlation coefficient values of the five different breathing paces were "near perfect" (>0.90) for all HRV indices: lnRMSSD, lnpNN50, lnLFpower, and lnHFpower. All Bland-Altman analyses (with just three incidental exceptions) showed good interchangeability of PPG- and ECG-derived HRV indices. No systematic evidence for proportional bias was found for any of the HRV indices. In addition, correspondence in resonance frequency detection was good with 76.6% agreement between PPG and ECG.

CONCLUSIONS

PPG is a potentially reliable and valid method for the assessment of HRV. PPG is a promising replacement of ECG assessment to measure resonance frequency during HRV-BF.

Exploring the meaning of unresolved loss and trauma in more than 1,000 Adult Attachment Interviews

Unresolved states of mind regarding experiences of loss/abuse (U/d) are identified through lapses in the monitoring of reasoning, discourse, and behavior surrounding loss/abuse in response to the Adult Attachment Interview. Although the coding system for U/d has been widely used for decades, the individual indicators of unresolved loss/abuse have not been validated independently of the development sample. This study examined the psychometric validity of U/d, using individual participant data from 1,009 parent-child dyads across 13 studies. A latent class analysis showed that subsets of commonly occurring U/d indicators could differentiate interviewees with or without unresolved loss/abuse. Predictive models suggested a psychometric model of U/d consisting of a combination of these common indicators, with disbelief and psychologically confused statements regarding loss being especially important indicators of U/d. This model weakly predicted infant disorganized attachment. Multilevel regression analysis showed no significant association between ratings of unresolved other trauma and infant disorganized attachment, over and above ratings of unresolved loss/abuse. Altogether, these findings suggest that the coding system of U/d may have been overfitted to the initial development sample. Directions for further articulation and optimization of U/d are provided.

Longitudinal relations between parenting stress and child internalizing and externalizing behaviors: Testing within-person changes, bidirectionality and mediating mechanisms

Introduction

Parenthood can be experienced as a pleasant but challenging period for parents, possibly accompanied by parenting stress. Early parenthood in particular is a vulnerable period as many parents experience biological and psychosocial changes related to new parenthood. Previous studies have shown that parenting stress is related to child behavior problems, but few studies have investigated the transactional relations across time between parenting stress and child internalizing and externalizing outcomes separately, examining within-person changes. The first aim of this study was to examine the transactional within-person associations of parenting stress and child internalizing and externalizing behavior problems across childhood from age 9 months to 9 years. As a second aim, we examined parenting as a possible underlying mechanism of the transactional associations by testing whether parental warmth and hostility mediate within-person associations of parenting stress and child behavior across time.

Method

Data were analyzed from the Growing Up in Ireland longitudinal child cohort study including 7,208 caregiver-child dyads at wave 1 (child's age 9 months), who were followed at child's age three (wave 2), five (wave 3), and 9 years (wave 5). Primary caregiver's and child's age and gender, household income, occupational status, educational status, partner status, and cultural background were covariates assessed at all waves. Data were analyzed using a random intercept cross-lagged panel model (CLPM) in R-lavaan.

Results

Bidirectional relations between parenting stress and child behavior were found for both internalizing and externalizing behavior from age 5 to 9, but not for earlier time points.

Discussion

Our results did not indicate mediating effects of parental warmth or parental hostility in the associations between parenting stress and child behavior problems. Therefore, we conclude that parenting stress and child internalizing as well as parenting stress and child externalizing behaviors have transactional associations from child's age 5 to 9 years. Future research examining transactional associations of parenting stress and child behaviors should investigate possible other mediations taking a within-person approach by utilizing the RI-CLPM.

Configurations of mother-child and father-child attachment as predictors of internalizing and externalizing behavioral problems: An individual participant data (IPD) meta-analysis

An unsettled question in attachment theory and research is the extent to which children's attachment patterns with mothers and fathers jointly predict developmental outcomes. In this study, we used individual participant data (IPD) meta-analysis to assess whether early attachment networks with mothers and fathers are associated with children's internalizing and externalizing behavioral problems. Following a pre-registered protocol, data from 9 studies and 1,097 children (mean age: 28.67 months) with attachment classifications to both mothers and fathers were included in analyses. We used a linear mixed effects analysis to assess differences in children's internalizing and externalizing behavioral problems as assessed via the average of both maternal and paternal reports based on whether children had two, one, or no insecure (or disorganized) attachments. Results indicated that children with an insecure attachment relationship with one or both parents were at higher risk for elevated internalizing behavioral problems compared with children who were securely attached to both parents. Children whose attachment relationships with both parents were classified as disorganized had more externalizing behavioral problems compared to children with either one or no disorganized attachment relationship with their parents. Across attachment classification networks and behavioral problems, findings suggest (a) an increased vulnerability to behavioral problems when children have insecure or disorganized attachment to both parents, and (b) that mother-child and father-child attachment relationships may not differ in the roles they play in children's development of internalizing and externalizing behavioral problems.

Actigraphic sleep and cortisol in middle childhood: A multivariate behavioral genetics model

To date, behavioral genetic studies investigated either sleep or cortisol levels in middle childhood, but not both simultaneously. Therefore, a pertinent question is the degree to which genetic factors and environmental factor contribute to the correlation between sleep and cortisol levels. To address this question, we employed the classical twin design. We measured sleep in 6-9-year-old twins (N = 436 twin pairs, “Together Unique” study) over four consecutive nights using actigraphy, and we measured morning cortisol on two consecutive days. Sleep duration, sleep efficiency, and wake episodes were used as indicators of sleep. Morning cortisol level was used as cortisol indicator. A structural equation model was fitted to estimate the contribution of additive genetic effects (A), shared (common) environmental effects, (C) and unique environmental effects (E) to phenotypic variances and covariances. Age, cohort, and sex were included as covariates. The heritability of sleep duration, sleep efficiency, and wake episodes were 52%, 45%, and 55%, respectively. Common environmental factors played no significant role. High genetic correlations between sleep duration and sleep efficiency and high genetic correlations between sleep efficiency and wake episodes were found. Shared environmental (29%) and unique environmental factors (53%) explained the variance in morning cortisol levels. Because the sleep and cortisol measures were found to be uncorrelated, we did not consider genetic and environmental contributions to the association between the sleep and cortisol measures. Our findings indicate that sleep duration, sleep efficiency, and wake episodes in children are mostly impacted by genetic factors and by unique environmental factors (including measurement error).

•

Sleep duration, efficiency and wake episodes are moderately heritable.

•

A high genetic correlation underlies sleep duration and sleep efficiency.

•

A high genetic correlation underlies sleep efficiency and wake episodes.

•

Cortisol and sleep were not (genetically) correlated.

Stress- and smoke free pregnancy study protocol: a randomized controlled trial of a personalized eHealth intervention including heart rate variability-biofeedback to support pregnant women quit smoking via stress reduction

BACKGROUND

Maternal smoking and stress during pregnancy are associated with adverse health effects for women themselves and are risk factors for adverse developmental outcomes of the unborn child. Smoking and stress seem to be intertwined in various ways. First, the majority of smoking pregnant women is of lower socio-economic status, which is associated with higher levels of perceived stress. Second, smoking women often report to smoke because they feel stressed. Third, quitting smoking often increases perceived stress levels initially. Therefore, effective interventions are needed to support women with smoking cessation by reducing stress. The aim of this study is to test the effectiveness of an eHealth intervention on stress reduction and smoking cessation.

METHODS/DESIGN

The Stress- and Smoke Free Start of Life (SSFSL) study is a randomized controlled trial (RCT) comparing a personalized eHealth intervention with a control condition. Inclusion criteria for the women are: (1) > 18 years of age, (2) < 28 weeks pregnant at recruitment, (3) currently smoking. Consenting participants will be randomly assigned to the intervention or control group. Participants allocated to the intervention group will receive an 8-week intervention delivered on their smartphone. The application includes psycho-education on pregnancy, stress, and smoking (cessation); stress-management training consisting of Heart Rate Variability-biofeedback; and a personalized stop-smoking-plan. Participants in the control condition will be invited to visit a webpage with information on pregnancy, stress, and smoking (cessation). Study outcomes will be collected via online questionnaires, at four timepoints: pre-intervention (baseline; t0), post-intervention (8 weeks + 1 day after t0; t1), follow up at two weeks after birth (t2), and follow up at three months after birth (t3). The primary outcome measure is self-reported smoking cessation. Secondary outcomes include daily self-reported number of cigarettes smoked, perceived stress, pregnancy experience, birth outcomes, and negative affectivity scores of the baby. Moreover, the mediating effect of stress reduction on smoking cessation will be examined, and possible moderators will be tested.

DISCUSSION

If the eHealth intervention is effective in smoking cessation among pregnant smoking women, it can be implemented as a tool into the health care in the Netherlands.

The Collaboration on Attachment Transmission Synthesis (CATS): A Move to the Level of Individual-Participant-Data Meta-Analysis

Generations of researchers have tested and used attachment theory to understand children's development. To bring coherence to the expansive set of findings from small-sample studies, the field early on adopted meta-analysis. Nevertheless, gaps in understanding intergenerational transmission of individual differences in attachment continue to exist. We discuss how attachment research has been addressing these challenges by collaborating in formulating questions and pooling data and resources for individual-participant-data meta-analyses. The collaborative model means that sharing hard-won and valuable data goes hand in hand with directly and intensively interacting with a large community of researchers in the initiation phase of research, deliberating on and critically reviewing new hypotheses, and providing access to a large, carefully curated pool of data for testing these hypotheses. Challenges in pooling data are also discussed.

Childbirth Experience Associated With Maternal and Paternal Stress During the First Year, but Not Child Attachment

Women, as well as their partners, can experience childbirth in many different ways. A negative childbirth experience may have adverse effects on the entire family, resulting, for instance, in parental stress symptoms and a weakened parent-child relationship. Parental stress, without sufficient resources to compensate for it, may also in and of itself negatively influence the parent-child relationship. This study contributes to the current knowledge of the psychological effects of childbirth experience by using longitudinal data collected with both self-reports and observational measures, as well as multiple informants (i.e., mothers and partners). The aim of this study was to investigate whether 1) women's retrospective birth experiences were related to maternal and paternal parenting stress, 2) birth experience was indirectly associated with child attachment via maternal stress, and 3) birth experience was directly related to child attachment. Data were collected from a mixed sample of community and at-risk primipara women (N = 1,364), as well as from their partners and children. Retrospective childbirth experience was measured 3 months postpartum with a latent factor consisting of five items asking about the feelings that women have about their childbirth. Parental stress was measured at 3 months postpartum for partners and 3 and 12 months postpartum for mothers using the adult domain of the parental stress index (PSI). Finally, parent-child attachment is observed in a subsample of 223 women and children at 12 months postpartum with the Strange Situation Procedure (SSP). Results show that women's birth experience was significantly related to both mothers' and their partners' parenting stress. However, birth experience was not related to child attachment, neither directly nor indirectly via maternal stress. These findings emphasize the long-lasting impact that childbirth may have on both parents. Future research is still needed to further investigate which protective factors may weaken the association between birth experience and parental stress.

Early Breastfeeding Experiences Predict Maternal Self-Efficacy During the Transition to Parenthood

Objective: Breastfeeding can be challenging for new mothers. Women with high breastfeeding self-efficacy are more likely to breastfeed with confidence and are more likely to succeed in breastfeeding. The aim of this prospective longitudinal study was to test whether breastfeeding self-efficacy and breastfeeding experiences were related to trajectories of self-efficacy in the parenting domain during the transition to parenthood. Materials and Methods: A group of 1,091 primiparous women completed questionnaires at 32 weeks of gestation (maternal self-efficacy) and 3 months after giving birth (maternal self-efficacy, breastfeeding self-efficacy, and breastfeeding experiences). Only the women who started breastfeeding and completed questionnaires at both time points were included in the analyses (N = 817). Results: High breastfeeding self-efficacy significantly predicted increased maternal self-efficacy through the transition to parenthood. A successful breastfeeding experience fully explained this effect. Conclusion: The mediating effect of positive breastfeeding experiences on the relationship of breastfeeding self-efficacy and the change of maternal self-efficacy during the transition to parenthood implies breastfeeding to be an early target to enhance maternal self-efficacy. By pointing out breastfeeding as a genuine challenge during prenatal maternity courses, it might prepare mothers for one of their first experiences of parenthood. As a result, successful breastfeeding could be a steppingstone from positive prenatal expectations to growing confidence as a parent.

Neighbourhood characteristics and prevalence and severity of depression: pooled analysis of eight Dutch cohort studies

BACKGROUND

Studies on neighbourhood characteristics and depression show equivocal results.AimsThis large-scale pooled analysis examines whether urbanisation, socioeconomic, physical and social neighbourhood characteristics are associated with the prevalence and severity of depression.

METHOD

Cross-sectional design including data are from eight Dutch cohort studies (n = 32 487). Prevalence of depression, either DSM-IV diagnosis of depressive disorder or scoring for moderately severe depression on symptom scales, and continuous depression severity scores were analysed. Neighbourhood characteristics were linked using postal codes and included (a) urbanisation grade, (b) socioeconomic characteristics: socioeconomic status, home value, social security beneficiaries and non-Dutch ancestry, (c) physical characteristics: air pollution, traffic noise and availability of green space and water, and (d) social characteristics: social cohesion and safety. Multilevel regression analyses were adjusted for the individual's age, gender, educational level and income. Cohort-specific estimates were pooled using random-effects analysis.

RESULTS

The pooled analysis showed that higher urbanisation grade (odds ratio (OR) = 1.05, 95% CI 1.01-1.10), lower socioeconomic status (OR = 0.90, 95% CI 0.87-0.95), higher number of social security beneficiaries (OR = 1.12, 95% CI 1.06-1.19), higher percentage of non-Dutch residents (OR = 1.08, 95% CI 1.02-1.14), higher levels of air pollution (OR = 1.07, 95% CI 1.01-1.12), less green space (OR = 0.94, 95% CI 0.88-0.99) and less social safety (OR = 0.92, 95% CI 0.88-0.97) were associated with higher prevalence of depression. All four socioeconomic neighbourhood characteristics and social safety were also consistently associated with continuous depression severity scores.

CONCLUSIONS

This large-scale pooled analysis across eight Dutch cohort studies shows that urbanisation and various socioeconomic, physical and social neighbourhood characteristics are associated with depression, indicating that a wide range of environmental aspects may relate to poor mental health.Declaration of interestNone.

Cohort profile: the Geoscience and Health Cohort Consortium (GECCO) in the Netherlands

PURPOSE

In the Netherlands, a great variety of objectively measured geo-data is available, but these data are scattered and measured at varying spatial and temporal scales. The centralisation of these geo-data and the linkage of these data to individual-level data from longitudinal cohort studies enable large-scale epidemiological research on the impact of the environment on public health in the Netherlands. In the Geoscience and Health Cohort Consortium (GECCO), six large-scale and ongoing cohort studies have been enriched with a variety of existing geo-data. Here, we introduce GECCO by describing: (1) the phenotypes of the involved cohort studies, (2) the collected geo-data and their sources, (3) the methodology that was used to link the collected geo-data to individual cohort studies, (4) the similarity of commonly used geo-data between our consortium and the nationwide situation in the Netherlands and (5) the distribution of geo-data within our consortium.

PARTICIPANTS

GECCO includes participants from six prospective cohort studies (eg, 44 657 respondents (18-100 years) in 2006) and it covers all municipalities in the Netherlands. Using postal code information of the participants, geo-data on the address-level, postal code-level as well as neighbourhood-level could be linked to individual-level cohort data.

FINDINGS TO DATE

The geo-data could be successfully linked to almost all respondents of all cohort studies, with successful data-linkage rates ranging from 97.1% to 100.0% between cohort studies. The results show variability in geo-data within and across cohorts. GECCO increases power of analyses, provides opportunities for cross-checking and replication, ensures sufficient geographical variation in environmental determinants and allows for nuanced analyses on specific subgroups.

FUTURE PLANS

GECCO offers unique opportunities for (longitudinal) studies on the complex relationships between the environment and health outcomes. For example, GECCO will be used for further research on environmental determinants of physical/psychosocial functioning and lifestyle behaviours.

Family Conflict and Resilience in Parenting Self-Efficacy Among High-Risk Mothers

Mothers with a history of institutional care in adolescence are often involved in high-conflict partner relationships, which may undermine relationships with children and confidence in oneself as a parent. Not all mothers think of themselves as bad parents under these circumstances. We turned to psychological resources as an explanation, focusing on mothers' trait self-control. The negative association between family conflict and parenting self-efficacy was tested for moderation by self-control among 104 mothers with a history of institutionalization for behavioral problems and delinquency during adolescence. We found a negative association between current family conflict and parenting self-efficacy among mothers with low self-control, and no significant association among mothers with high self-control. This study draws attention to the needs of high-risk mothers in their parenting role and demonstrates that self-control is a potential resource for mothers to balance the load presented by conflict in their families. The findings suggest new avenues for intervention.

Effects of Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) for Young Foster Children with Severe Behavioral Disturbances

Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) has thus far only been tested for diminishing behavior problems in the US. This study tested relative efficacy of MTFC-P on multiple outcomes against treatment as usual in the Netherlands (TAU; Study I), and regular foster care (Study II). The sample included 55 children that received MTFC-P, 23 children received TAU and 30 children from regular foster care (RFC). Changes in behavioral and relationship functioning, trauma symptoms, hypothalamic-adrenal-pituitary (HPA-) axis functioning, and caregiving stress were assessed via questionnaires, interviews, and salivary cortisol. Outcomes of Study I were evaluated using a randomized controlled design and quasi-experimental design, outcomes of Study II according to non-equivalent group comparison. No evidence was found for relative efficacy of MTFC-P over TAU. A treatment effect was found on trauma symptoms, in favor of TAU. Outcomes of Study II revealed that whereas caregiving stress and secure base distortions were significantly more severe at baseline in MTFC-P compared to RFC, post treatment differences were no longer significant. However, percentages of symptoms of disinhibited attachment and attachment disorder were nearly equal between groups at baseline, while post treatment percentages indicated significantly more symptoms in MTFC. In addition, results revealed a significant difference in the severity of externalizing problems post treatment, in favor of RFC. The results obtained within this study indicate that children in MTFC-P and usual treatment foster care in the Dutch context improved similarly, thus not showing the same advantages that MTFC-P has demonstrated in the US. Results should be interpreted with caution due to lower than planned power. Findings underscore the challenges of testing novel treatments across contexts with highly different child welfare provisions.

From prenatal anxiety to parenting stress: a longitudinal study

The objective of this study was to explore how maternal mood during pregnancy, i.e., general anxiety, pregnancy-specific anxiety, and depression predicted parenting stress 3 months after giving birth, thereby shaping the child's early postnatal environmental circumstances. To this end, data were used from 1073 women participating in the Dutch longitudinal cohort Generations², which studies first-time pregnant mothers during pregnancy and across the transition to parenthood. Women filled out the State Trait Anxiety Inventory (STAI), Pregnancy-Related Anxiety Questionnaire-revised (PRAQ-R), and Beck Depression Index (BDI) three times during pregnancy: at 12, 22, and 32 weeks gestational age. Three months postpartum, a parenting stress questionnaire was filled out yielding seven different parenting constructs. Latent scores were computed for each of the repeatedly measured maternal mood variables with Mplus and parenting stress constructs were simultaneously regressed on these latent scores. Results showed that trait anxiety and pregnancy-specific anxiety were uniquely related to almost all parenting stress constructs, taking depression into account. Early prevention and intervention to reduce maternal anxiety in pregnancy could hold the key for a more advantageous trajectory of early postnatal parenting.

Parenting self-efficacy moderates linkage between partner relationship dissatisfaction and avoidant infant-mother attachment: A Dutch study

The early infant-mother attachment relationship is part of a network of close relationships in which the relationship between parents is especially relevant. Evidence for linkages between maternal satisfaction with the partner relationship and infant-mother attachment is equivocal. The current study tested whether associations between partner relationship dissatisfaction and infant-mother attachment quality might be conditional on mothers' parenting self-efficacy. The bivariate effect of partner relationship dissatisfaction on infant-mother attachment as well as moderation of this effect by parenting self-efficacy was tested in a sample of 260 infant-mother dyads 1 year after birth. There was no direct effect of partner dissatisfaction on attachment. Unexpectedly, for high parenting self-efficacy, greater partner dissatisfaction increased the odds of an avoidant infant attachment (compared with a disorganized) whereas, for low parenting self-efficacy, greater partner dissatisfaction decreased the odds of an avoidant infant attachment (compared with secure and disorganized). Findings underline the importance of parenting cognitions for understanding contextual factors of infant-mother attachment quality. (PsycINFO Database Record

Weakened Resilience in Parenting Self-Efficacy in Pregnant Women Who Were Abused in Childhood: An Experimental Test

This study tested experimentally whether the combination of a history of childhood abuse and confrontation with difficult infant temperament is associated with negative changes in parenting self-efficacy. First-time pregnant women (N = 243) participated in the Adult Attachment Interview, which was used to assess the occurrence of abuse by parents in childhood and unresolved representations, and completed a task asking them to respond to infant cries. Sixty of the 243 participants (25%) experienced childhood abuse, mostly physical or sexual. The task simulated infant temperamental difficulty by manipulating soothing success in order to reflect an easy-to-soothe (80% soothing success) and a difficult-to-soothe infant (20% soothing success). Both after baseline and after each of the two stimulus series women assessed their parenting self-efficacy. Women who reported childhood abuse did not differ from women who reported no childhood abuse in parenting self-efficacy at baseline or in response to the easy-to-soothe infant (relative to baseline), but decreased more in parenting self-efficacy following the difficult-to-soothe infant. Effects did not vary according to resolution of trauma. These findings suggest that in response to infant temperamental difficulty, women who experienced childhood abuse may more easily lose confidence in their parenting abilities, which underlines the importance of preparing at-risk women for the possible challenges that come along with parenthood.

The interrelationship between pregnancy-specific anxiety and general anxiety across pregnancy: a longitudinal study

BACKGROUND

High levels of prenatal maternal anxiety - either pregnancy-specific anxiety or general anxiety - may have detrimental effects on both the mother and her child. It is currently unknown how these two different expressions of anxiety influence each other over time during pregnancy.

AIMS

This study aimed to describe the relationship between state, trait and pregnancy-specific anxiety levels across pregnancy.

METHODS

Longitudinal data from three data-waves of a large-scaled sample of nulliparous normal risk pregnant women were used to display associations over time by means of autoregressive and cross-lagged panel models.

RESULTS

Cross-lagged, cross-time pathways from pregnancy-specific anxiety to state as well as trait anxiety were positively significant, while vice versa the most consistent links were found from trait anxiety to pregnancy-specific anxiety.

CONCLUSIONS

We conclude that pregnancy-specific anxiety and general anxiety appear to influence each other over time, resulting in heightened anxiety for some soon-to-be mothers.

Disturbances in attachment: inhibited and disinhibited symptoms in foster children

BACKGROUND

Previous DSM-versions recognized an inhibited and a disinhibited subtype of the Reactive Attachment Disorder (RAD). The current DSM-5 distinguishes two different disorders, instead of two subtypes of RAD. This study examined whether a split-up of the subtypes is valid.

METHOD

In 126 foster children, attachment disorder symptoms were assessed with the Disturbances of Attachment Interview. Forms of pathogenic care were identified based on dossier analyses. Associations between symptoms of attachment disorder with internalizing and externalizing problems (Child Behavior Checklist and Teacher Report Form) were examined.

RESULTS

Omnibus tests showed no significant association between type of symptoms and type of pathogenic care. Exploratory analyses did reveal an univariate association between disinhibited symptoms and history of physical abuse. Disinhibited symptoms were associated with more internalizing and externalizing problems (d's < 0.50).

CONCLUSION

The distinction of inhibited and disinhibited subtypes of RAD seems valid regarding their emotional and behavioral correlations. Whereas inhibited symptoms lack a correlation, disinhibited symptoms seem to have an externalizing and internalizing correlation.

Parenting self-efficacy predicts perceptions of infant negative temperament characteristics, not vice versa

Infant temperamental characteristics have been found associated with decreasing parenting self-efficacy (PSE) during the first year after birth, which has been generally interpreted as a child effect on the parent. To test direction of effects, PSE was assessed during the third trimester of pregnancy and twice after birth together with perceived infant temperament in a group of first-time pregnant women (N = 616). Cross-lagged path analysis showed that PSE, even when assessed prior to birth, predicted characteristics of infant negative temperament. Infant negative temperamental characteristics were concurrently, but not prospectively, associated with decreased PSE. These findings indicate that perceptions of infant temperament may partly be shaped by parents' self-perception, rather than the other way around.

The effectiveness of Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) for young children with severe behavioral disturbances: study protocol for a randomized controlled trial

BACKGROUND

Among children placed out of home, behavioral and relationship functioning is often problematic. When placed in foster care, problems tend to persist or even worsen and increase the risk of placement breakdown. Multidimensional Treatment Foster Care for Preschoolers is an intensive behavior-focused program for young foster children (3 to 7 years) aiming to provide children with a positive and stimulating foster family setting and individually tailored behavioral interventions. This study will be the first to examine the effectiveness of Multidimensional Treatment Foster Care for Preschoolers outside the US and to examine the effectiveness across a broader range of problems related to foster care.

METHODS

This is a randomized controlled trial, wherein we expect to include 80 child-foster carer dyads. Forty dyads will be assigned to Multidimensional Treatment Foster Care for Preschoolers and 40 to treatment as usual, following pre-randomization. Data to be gathered concern problem behavior, symptoms of attachment disorder, post-traumatic stress symptoms, quality of life, hypothalamic-adrenal-pituitary axis functioning, parental stress and autonomic reactivity, to be collected via questionnaires, observations, interviews, saliva and recording at six time-points over 24 months. To compare treatment outcomes, Fisher's exact tests and repeated measures (mixed models) and independent t-tests will be used. All analyses will be performed following the intention-to-treat principle.

DISCUSSION

Examining the generalizability of previous findings in the US and extending these previous findings is a step towards improving knowledge about treatment of young foster children with severe behavioral, emotional and attachment problems.

Multidimensional treatment foster care for preschoolers: early findings of an implementation in the Netherlands

Multidimensional Treatment Foster Care (MTFC) has been shown to be an evidence based alternative to residential rearing and an effective method to improve behavior and attachment of foster children in the US. This preliminary study investigated an application of MTFC for preschoolers (MTFC-P) in the Netherlands focusing on behavioral outcomes in course of the intervention. To examine the following hypothesis: "the time in the MTFC-P intervention predicts a decline in problem behavior", as this is the desired outcome for children assigned to MTFC-P, we assessed the daily occurrence of 38 problem behaviors via telephone interviews. Repeated measures revealed significant reduced problem behavior in course of the program. MTFC-P promises to be a treatment model suitable for high-risk foster children, that is transferable across centres and countries.

Children's physical health complaints after exposure to intimate partner violence

OBJECTIVES

A clear association between exposure to intimate partner violence (IPV) and children's physical health is still not well determined, because adverse effects might be explained by the confounding detrimental effects of other traumatic experiences. This study investigated whether children exposed to IPV have higher risks for physical health complaints compared to children in a general population sample. Second, health complaint differences were explored between IPV witnesses and those who in addition experienced other forms of abuse or neglect.

DESIGN

Risk estimates for 21 everyday physical health complaints were made for children exposed to IPV compared to a general population sample using odds ratios.

METHODS

Primary caregivers of 275 child witnesses of IPV (6-12 years of age) referred to several specialized mental health or child welfare institutes throughout the Netherlands (2004-2009) reported on children's somatic complaints using 21 items of the Child Behaviour Checklist (CBCL; Achenbach & Rescorla, 2001) reflecting sleeping, eating, pain complaints, and self-harm.

RESULTS

Compared to a population sample (n= 903), child witnesses more often experienced health complaints, in particular, more eating, sleeping, and pain problems and more self-harm. Few differences in health complaints were found between child witnesses with and without additional adverse experiences of maltreatment.

CONCLUSIONS

The degree of physical health complaints in children exposed to IPV is considerable, whether or not they were also victims of other forms of abuse. Early attention to everyday health complaints in children exposed to IPV might prevent more serious health problems in adolescence and adulthood.

Children with disrupted attachment histories: interventions and psychophysiological indices of effects

Diagnosis and treatment of children affected by disruptions of attachment (out of home placement, multiple changes of primary caregiver) is an area of considerable controversy. The possible contribution of psychobiological theories is discussed in three parts. The first part relates the attachment theoretical perspective to major psychobiological theories on the developmental associations of parent-child relationships and emotional response. The second part reviews studies of autonomic reactivity and HPA-axis activity with foster children, showing that foster children show more reactivity within physiological systems facilitating fight or flight behaviours rather than social engagement, especially foster children with atypical attachment behaviour. The third part is focused on treatment of children suffering from the consequences of disrupted attachment, based on a psychotherapy study with psychophysiological outcome measures. Implications are discussed for theory, diagnosis, and intervention.

Autonomic reactivity of children to separation and reunion with foster parents

OBJECTIVE

To determine whether foster children showed different autonomic nervous system activity on separation and reunion than control children. Autonomic nervous system activity in foster children was examined in relation to time in placement and disinhibited attachment.

METHOD

The sample included 60 foster and 50 control children between 2 and 7 years of age who participated with their caregivers in a modified Strange Situation. Heart rate, respiratory sinus arrhythmia (RSA), and pre-ejection period were monitored continuously. Foster caregivers reported disinhibited symptoms on the Disturbances of Attachment Interview.

RESULTS

The Strange Situation elicited less RSA reactivity in foster children. Differences in RSA, heart rate, and pre-ejection period responses on the specific separation and reunion episodes were not significant. RSA responses on separation from the stranger and on reunion with the foster caregiver were partly explained by time in placement and disinhibited attachment.

CONCLUSIONS

Early experiences of relationship disruptions in foster children as well as short placements may have an impact on children's adaptation to environmental and relational challenges. Stable placement may facilitate adaptive affect regulation, except for children with disinhibited symptoms.

Physiological effects of separation and reunion in relation to attachment and temperament in young children

This study examined physiological effects of separation and reunion in a sample 3- to 6-year-old children. Using continuous ambulatory recording, changes in heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) were compared across the episodes of a separation-reunion procedure based on the strange situation. RSA decreased significantly over the course of the procedure as well as on separation from the parent and not the stranger, supporting that separation from the attachment figure elicited vagal withdrawal in young children. The absence of significant PEP effects suggest that the separation-reunion procedure, and more specifically separation from the parent, was not threatening enough to activate the sympathetic nervous system, even if children were insecure attached and inhibited with regard to strangers. Some of the variability in HR increases to reunion was explained by younger age. The findings highlight the role of the ANS as a regulatory process in the parent-child relationship.
