Intergenerational transmission of maternal prenatal anxiety to infant fearfulness: the mediating role of mother-infant bonding.

PURPOSE: This study is the first to directly investigate the mechanistic role of maternal bonding toward her infant in the early intergenerational pathway of risk from maternal anxiety to infant fearfulness. METHODS: Mothers (N = 216; Mage=32.78) reported on their anxiety and bonding at four time-points between pregnancy and ten-months postpartum. At four and ten-months postpartum, infant temperamental precursors of anxiety were assessed through maternal report and observation. RESULTS: Cross-lagged longitudinal path modeling indicated a significant link between prenatal maternal anxiety and infant temperamental fearful withdrawal at 10-months postpartum (R2 = 0.117), which was fully explained by decreased maternal bonding at one-month postpartum and increased infant temperamental negative reactivity at 4-months postpartum. CONCLUSION: Results support the need to foster maternal bonding in preventive perinatal care, particularly in the context of maternal anxiety.

The importance of differentiating between cold and hot response inhibition in the parenting context, when examining associations with harsh parenting.

Harsh parenting (HP) entails physical and verbal expressions of anger and aggression toward children, usually observed as response to child negative emotionality. Abundant previous research has indicated the detrimental negative impacts of HP on children's developing behavioral, cognitive social, and emotional capacities, highlighting the need for examining its determinants. Among other determinants, previous research has suggested the importance of parents' cognitive regulatory capacity for inhibiting inappropriate behavioral responses (response inhibition; RI). Specifically, parents' RI may help prevent the translation of harsh tendencies into HP behavior. Previous research in the field has typically focused on investigating parents' trait capacities of RI, though particular state capacities of RI in the context of children's negative emotions might be more relevant. The current study is the first to investigate whether the latter more specifically associates with HP. Data were collected in 2019. Participants were 98 first-time parents (Mage = 31.85 years, SDage = 4.22), 68.0% mothers. Parents completed a computerized Go/No-Go paradigm, measuring RI in seven different background conditions: one neutral-gray background condition and six emotional face background conditions (infant negative/positive/neutral emotional faces and adult negative/positive/neutral emotional faces). Next, participants reported on their HP. Results indicated that parents' RI was significantly lower in infant emotional contexts, as compared to adult emotional contexts. Moreover, parents' RI was significantly lower in infant negative emotional contexts, compared to infant positive emotional contexts and infant neutral emotional contexts. Importantly, lower RI in infant negative emotional contexts is associated with increased HP. These results have important implications for affective science as well as practical implications for early detection and intervention of HP tendencies toward infants.

What works for whom? Moderators in parental reflective functioning intervention.

The DUET program (a group intervention) aims to enhance parental reflective functioning (PRF). We examined whether pretreatment levels of key outcomes as well as individual parental and family-environment characteristics predicted improvement after intervention with the DUET program. One hundred forty-two parents (native Israelis; mean age = 34.84 years) of preschool children (n = 107; mean child age = 4.3 years; 53% female) were assessed before, after, and 6 months following the intervention. Results indicated significant associations between lower levels of key outcomes at the pretreatment assessment and greater improvement after treatment in PRF, child self-regulation, and child self-distraction strategies. Furthermore, two subgroups of families were uncovered based on individual parental and family-environment characteristics: low-distress and high-distress parents. Following intervention, the high-distress group showed greater improvement in parental sensitivity and child problem behavior, whereas the low-distress group reported greater improvement in locus of control. Clinical and future directions are discussed.

Persistent symptoms of maternal post-traumatic stress following childbirth across the first months postpartum: Associations with perturbations in maternal behavior and infant avoidance of social gaze toward mother.

Recent literature identifies childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth (PTS-FC). The current study examines whether stable symptoms of PTS-FC during the early postpartum period may impose risk for perturbations in maternal behavior and infant social-engagement with mother, controlling for comorbid postpartum internalizing symptoms. Mother-infant dyads (N = 192) were recruited from the general population, during the third trimester of pregnancy. 49.5% of the mothers were primipara, and 48.4% of the infants were girls. Maternal PTS-FC was assessed at 3-day, 1-month and 4-month postpartum, via self-report and clinician-administered interview. Latent Profile Analysis generated two profiles of symptomology: "Stable-High-PTS-FC" (17.0%), and "Stable-Low-PTS-FC" (83%). Membership in the "Stable-High-PTS-FC" profile associated with perturbed maternal sensitivity, which was in turn significantly associated with infant avoidance of social gaze toward mother (Indirect effect ß = -0.15). Results suggest the need for early screening and inform the planning of early preventive interventions.

Preventing risk for posttraumatic stress following childbirth: Visual biofeedback during childbirth increases maternal connectedness to her newborn thereby preventing risk for posttraumatic stress following childbirth.

OBJECTIVE: Mounting evidence indicates the detrimental impact of posttraumatic stress following childbirth (PTS-FC). Nevertheless, research on preventive strategies is scarce. We recently reported that ultrasound visual biofeedback during second stage of labor was associated with immediate beneficial medical outcomes (increased pushing efficacy, decreased perineal tearing), as well as greater feelings of maternal connectedness toward her newborn immediately postlabor. The current study assessed the potential longer-term psychological benefits of these outcomes in buffering risk for PTS-FC. The study follows up the previously reported sample to examine the longitudinal clinical effect of the visual biofeedback intervention on symptoms of acute stress at 2 days postpartum and subsequent symptoms of PTS-FC at 1 month postpartum. METHOD: A sample of 26 nulliparous women received visual biofeedback and was compared to a group of women receiving standard obstetrical coaching. Maternal feelings of connectedness and acute stress symptoms were assessed 2 days postpartum and PTS-FC was assessed 1 month postpartum. RESULTS: Double-mediation analyses revealed a significant indirect relation between visual biofeedback and decreased PTS-FC symptoms 1 month postpartum. The relation was significantly mediated by increased feelings of maternal connectedness immediately postpartum, which in turn was associated with decreased symptoms of acute stress 2 days postpartum. CONCLUSIONS: These results suggest that the visual biofeedback intervention during childbirth may decrease risk for PTS-FC. Importantly, findings suggest the preventive potential of fostering feelings of maternal connectedness toward her newborn to reduce symptoms of PTS-FC.

A machine learning approach to identifying pregnant women's risk for persistent post-traumatic stress following childbirth.

INTRO: Recent literature identifies childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth (PTS-FC). Especially when persistent, PTS-FC may interfere with mothers' caregiving and associated infant development, underscoring the need for accurate predictive screening of risk. Drawing on recent developments in advanced statistical modeling, the aim of the current study was to identify a set of prenatal indicators and prediction rules that may accurately identify pregnant women's risk for developing symptoms of PTS-FC which persist throughout the early postpartum period. METHODS: 182 women from the general population completed a comprehensive set of approximately 200 potentially predictive questions during pregnancy, and subsequently reported on their acute stress and PTS-FC at three days, one month, and three months postpartum (self-report and clinician-administered interview). Based on the postpartum acute stress and PTS-FC data, women were classified into profiles of "Stable-High-PTS-FC" and "Stable-Low-PTS-FC" by means of Latent-Class Analyses. Prenatal data were modeled to identify women at risk for "Stable-High PTS-FC". RESULTS: Employing machine-learning decision-tree analyses, a total of 36 questions and 7 prediction-rules were selected. Based on a cost-rate of 15 versus 100 for false-negative "Stable-Low-PTS-FC" versus false-negative "Stable-High-PTS-FC", the final model showed 80.6% accuracy for "Stable-High-PTS-FC" prediction. DISCUSSION: This study identifies a short set of questions and prediction rules that may be included in future large-scale validation studies aimed at developing and validating a brief PTS-FC screening instrument that could be implemented in general population prenatal healthcare practice. Accurate screening would allow for selective administering of preventive interventions towards women at risk.

Prospective risk from prenatal anxiety to post traumatic stress following childbirth: The mediating effects of acute stress assessed during the postnatal hospital stay and preliminary evidence for moderating effects of doula care.

OBJECTIVE: Growing literature has identified childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth. The current study is the first to prospectively examine a pathway of risk from mothers' prenatal trait-anxiety, to Acute-Stress-Immediately-Following-Childbirth, and later symptoms of Post-Traumatic-Stress-Following-Childbirth, in a low-risk community sample. Auxiliary analyses explored whether doula care during childbirth moderated risk. METHOD: 149 pregnant women were randomly selected. Prenatal trait-anxiety was assessed toward the end of pregnancy, Acute-Stress-Immediately-Following-Childbirth at two-days post-partum, and symptoms of Post-Traumatic-Stress-Following-Childbirth at one-month post-partum. RESULTS: Results indicated a significant indirect pathway from prenatal trait-anxiety to Post-Traumatic-Stress-Following-Childbirth, through Acute-Stress-Immediately-Following-Childbirth. Two groups were generated ad hoc for auxiliary analyses: participants who opted to receive doula care during childbirth (n=21; 14%) versus participants who received care as usual (n=128; 86%). Analyses provided preliminary support for doula care as a potential moderator of risk. CONCLUSIONS: Results point toward prenatal trait-anxiety and Acute-Stress-Immediately-Following-Childbirth as significant risk factors for Post-Traumatic-Stress-Following-Childbirth. Findings inform preventive screening implicating the prenatal period as well as the postnatal hospital stay as important time windows for preventive screening. Finally, preliminary support for moderating effects of doula care suggest that preventive interventions administered during the perinatal period may effectively reduce anxiety-related risk for Post-Traumatic-Stress-Following-Childbirth.

Pectin and phytic acid reduce mineral bioaccessibility in cooked common bean cotyledons regardless of cell wall integrity.

Common bean cotyledons are rich in minerals (Mg, Ca, Fe and Zn), but they also contain natural barriers that can potentially prevent mineral absorption during digestion. In this study, both the cell wall integrity and mineral chelators/antinutrients (phytic acid and pectin) were investigated as natural barriers in common bean cotyledons. To examine the cell wall integrity as a physical barrier for mineral diffusion, soluble mineral content was determined in a cooked cotyledon sample before and after disruption of intact cell walls. While this study showed that the cell wall in cooked common bean cotyledons does not hinder mineral diffusion, it also demonstrated that the presence of antinutrients decreases mineral bioaccessibility. It was shown that a certain mineral fraction is naturally bound to phytic acid and/or pectin and, by enzymatically degrading these antinutrients, the antinutrient-chelated mineral fraction decreased. Moreover, although pH changes are occurring during simulated digestion experiments, which might affect charge of the antinutrients and thus their chelating capacity for minerals, no difference in mineral distribution over antinutrients was observed due to digestion. In addition, this study showed that mineral bioaccessibility in common bean cotyledons could be potentially increased by degrading antinutrients during digestion in the small intestinal phase.

The impact of postharvest storage and cooking time on mineral bioaccessibility in common beans.

Mineral (Mg, Ca, Fe and Zn) bioaccessibility in common beans was evaluated taking into consideration the common bean food chain from postharvest storage over processing (soaking and cooking) until consumption. Beans were stored under realistic tropical conditions (35 °C and 80% RH) which resulted in significantly different cooking behaviour after 8 weeks compared to freshly harvested beans. Based on postcooking hardness, different storage times were selected: unstored, 8 and 20 weeks. Independently of storage conditions, beans were soaked overnight and cooked for 30, 60 or 120 min. The mineral bioaccessibility decreased with increase in both storage and cooking times. Decrease in mineral bioaccessibility with increasing storage time was proved to be the result of increasing mineral chelation of cell wall polymers (e.g. pectin). Additionally, we hypothesize that by cooking, mineral chelators become more accessible, e.g. through pectin solubilization phenomena, in turn capturing more free minerals leading to a reduced mineral bioaccessibility.

Moderating the Risk for Attention Deficits in Children with Pre-Adoptive Adversity: The Protective Role of Shorter Duration of out of Home Placement and Children's Enhanced Error Monitoring.

Early institutional-deprivation has been found to increase risk for inattention/hyperactivity (ADHD). Notably, studies suggest that children with a history of adversity evidencing an enhanced ERP (the error-related-negativity; ERN) may be protected against attention problems. However, such protective effects of the ERN have been studied in children whom typically experienced residential instability. It is unknown whether error-monitoring is similarly protective for children with stable post-deprivation placements. The present study examined the protective effect of the ERN in a sample of children who experienced at least 3-years of stable, relatively enriched caregiving after being internationally-adopted as infants/toddlers from institutional-care. We included two groups of children adopted internationally before age three, one group adopted from institutional-care (PI:n = 80) and one comparison group adopted from foster-care (FC;n = 44). A second comparison group consisted of non-adopted children (NA;n = 48) from demographically comparable families. At five-years of age, we assessed child ADHD symptoms (parent-report) and behavioral performance and neural correlates of error-monitoring (Go/No-Go task). PI children displayed lower Go/No-Go accuracy relative to FC children, and higher levels of ADHD symptoms relative to NA controls. In both FC and PI groups, longer duration of pre-adoptive out-of-home placement was associated with inattention, especially for children with deficits in error-monitoring. Enhancing cognitive control in the form of error monitoring might be a useful intervention target to protect children from some of the negative outcomes associated with adverse early care. Furthermore, results underscore that regardless of type of pre-adoptive care, we should aim to place children in stable/permanent homes as early as possible.

Ageing, dehulling and cooking of Bambara groundnuts: consequences for mineral retention and in vitro bioaccessibility.

Postharvest storage of legumes is a strategy to ensure food security. However, the hard-to-cook phenomenon, partly explained by pectin-cation-phytate theory, may develop during storage. Based on this theory, minerals could be redistributed within the matrix, affecting the concentration of free/bound minerals and hence their bioaccessibility. Therefore, this study investigated the influence of storage-induced ageing and subsequent dehulling, soaking and cooking treatments on the concentration and in vitro bioaccessibility of Ca, Mg, Fe and Zn in Bambara groundnuts. ICP-OES was performed to determine Ca, Mg, Fe and Zn concentrations after applying different treatments and after simulated digestion in the context of bioaccessibility determination. This study illustrates that while the seed coat is rich in Ca (51%), it contains only less than 15% of Mg, Fe or Zn. Hence, dehulling negatively influenced Ca, but not Mg, Fe or Zn concentration. During soaking, up to 10% or 56% of the initial Mg concentration leaches into whole or dehulled seeds, respectively. Prolonging the cooking time (300 min) of whole aged Bambara groundnuts (32 weeks), necessary for obtaining palatable textures, decreased the overall Mg, Fe and Zn concentrations by 72%, 57% and 48%, respectively. Storage-induced ageing significantly decreased Ca solubility and bioaccessibility. Bioaccessibility of trace minerals in Bambara groundnuts is low, especially for Fe, and cannot be improved by dehulling or cooking treatments. Ageing did not influence Fe and Zn bioaccessibility. Populations relying on both fresh and aged Bambara groundnuts may still be at risk for mineral deficiencies.

Barriers impairing mineral bioaccessibility and bioavailability in plant-based foods and the perspectives for food processing.

Plant-based foods gain more importance since they play a key role in sustainable, low-meat and healthy diets. In developing countries, these food products, especially legumes and cereals, are important staple foods. Nevertheless, the question arises on how efficient they are to deliver minerals and if it is useful to encourage their consumption to reduce the prevalence of mineral deficiencies? This review paper focuses on the discrepancy between the mineral content and the amount of minerals that can be released and absorbed from plant-based foods during human digestion which can be attributed to several inherent factors such as the presence of mineral antinutrients (phytic acid, polyphenols and dietary fiber) and physical barriers (surrounding macronutrients and cell wall). Further, this review paper summarizes the effects of different processing techniques (milling, soaking, dehulling, fermentation, germination and thermal processing) on mineral bioaccessibility and bioavailability of plant-based foods. The positive impact of these techniques mostly relies on the fact that antinutrients levels are reduced due to removal of fractions rich in antinutrients and/or due to their leaching into the processing liquid. Although processing can have a positive effect, it also can induce leaching out of minerals and a reduced mineral bioaccessibility and bioavailability.

The association between mothers' and daughters' positive affect is moderated by child cardiac vagal regulation.

INTRODUCTION: Extensive research has supported the importance of children's positive affect in fostering prosperous psychosocial adjustment. Children's positive affect is believed to be significantly shaped by their environment in general and their caregivers' positive affect in particular. The current study investigates the role of child cardiac vagal regulation, a psychophysiological marker for social engagement, in shaping the association between maternal positive affect and child positive affect. METHODS: Mothers and daughters (ndyads  = 28) participated in two experimental conditions. In the non-interactive condition, they separately drew a picture without interacting. In the cooperative condition, they drew a picture together. We measured child respiratory sinus arrhythmia (RSA), a widely used indicator of cardiac vagal regulation, during both conditions. We also coded maternal and child positive affect during the cooperative condition. RESULTS: Maternal positive affect was related to child positive affect, but only for children with medium-to-high tonic levels of RSA and RSA increases from non-interaction to interaction. DISCUSSION: Results suggest that child RSA plays a significant role in positive emotion socialization, by making children more susceptible to the emotional cues of their caregivers. Hence, child RSA should be taken into account in preventive and therapeutic efforts regarding child positive affect socialization.

When somatization is not the only thing you suffer from: Examining comorbid syndromes using latent profile analysis, parenting practices and adolescent functioning.

Understanding somatization presents a challenge to clinicians because it is often associated with other syndromes. We addressed somatization's comorbidity with other internalizing syndromes (anxiety, depression, withdrawal) using latent profile analysis. A representative sample of 3496 Israeli middle and high-school youths reported their internalizing symptoms, perceived parenting practices, psychosocial functioning, and health behaviors. Four profiles, similar across age and gender, were identified: overall-low (65.4%), moderately-high anxiety/depression/withdrawal (24.4%), high somatization (4.8%), and overall-high (5.4%). MANOVAs and follow-up ANOVAs revealed that for the most part the overall-high profile evinced the worst parenting, psychosocial functioning, and health behaviors (smoking and drinking), while the overall-low group evinced the best. For most variables the high somatization and moderately high profiles displayed midway results. However, the moderately-high profile reported higher levels of harsh parenting than the high somatization profile. The high somatization profile reported similar or higher levels of smoking, risk taking, vandalism, and rule violation than the overall-high group. High somatization, either alone or alongside anxiety, depression, and withdrawal, was associated with disruptive and risk-taking behaviors. This link might reflect problems in emotion and anger regulation and become stronger in adolescence because of dysregulation processes characterizing this period. Implications for practice are discussed.

"I will guide you" The indirect link between overparenting and young adults' adjustment.

This study addresses knowledge gaps regarding family dynamics, and identifies young adults at-risk for psychopathological symptoms. In particular, we examined overparenting and its associations with young adults' adjustment (distress and interpersonal sensitivity). Both direct and indirect relations were assessed, the latter through young adults' relational characteristics (attachment, psychological control perception, and boundaries diffusion perception). Also, the contribution of gender of parents and young adults was addressed. Questionnaires were collected from 89 Jewish-Israeli intact families. Mothers reported significantly more use of overparenting than fathers. More overparenting of fathers had a direct relation with less adjustment in young adults. This direct relation was partially mediated by higher levels of young adults' attachment anxiety (for the dependent variables distress and interpersonal sensitivity) and young adults' perceptions of parental psychological control (for the dependent variable distress). More overparenting of mothers was related to less interpersonal sensitivity for male young adults and for young adults who reported less parental psychological control. This study showed that parenting qualities and their interplay with young adults' relational characteristics continue to play an important role in the lives of young adult offspring. Therefore, clinicians dealing with young adults at risk for, or suffering from, psychopathology, should be attentive to overparenting and its possible implications.

The relation between parenting stress and adolescents' somatisation trajectories: a growth mixture analysis.

OBJECTIVE: The impact of somatisation in adolescence is substantial. Knowledge on (predictors of) individual-level development of somatisation is necessary to develop tailored treatment. The current study assessed individual-level development of somatisation by means of latent mixed modelling. Parenting stress was included as a predictor of somatisation trajectory membership and within-trajectory variation. METHODS: A total of 1499 adolescents and one of their parents (mostly the mother) agreed to participate. Questionnaires were administered when the adolescents were respectively 12-13 (T1), 13-14 (T2), and 14-15 (T3) years old. Adolescents reported on their somatisation, parents on their parenting stress. RESULTS: Four individual somatisation trajectories were found: increased, long-term low, long-term high, and decreased. Higher early parenting stress (T1) significantly predicted less favourable trajectory membership (increased and long-term high). The relation between later parenting stress (T2 and T3) and somatisation depended on trajectory membership. For adolescents in the long-term high and decreased somatisation trajectories, lower T2 and T3 parenting stress was related to higher somatisation, while for adolescents in the long-term low and increased trajectories, higher T2 and T3 parenting stress was related to higher somatisation. CONCLUSIONS: The results support a general recommendation to prevent the onset of high levels of parenting stress. In addition, for families in which high levels of parenting stress already exist, clinicians should be aware of natural fluctuations in parenting stress, its associated features (e.g., aspects of overall care, like looking for professional help) and of the consequences this might have for the adolescent.

The association between parenting behavior and somatization in adolescents explained by physiological responses in adolescents.

INTRODUCTION: This study adds to the knowledge on somatization in adolescents by exploring its relation with parenting behavior and the mediating/moderating role of physiological responses in adolescents to parenting behavior. METHOD: Eighteen adolescents with high and 18 adolescents with low somatization scores and their mothers completed a discussion task, from which observed parenting behavior scores were derived. Skin conductance in adolescents was measured before and during the discussion. RESULTS: For adolescents with high levels of physiological responses, unadaptive parenting was related to a higher chance of high somatization scores. For low physiologically responsive adolescents, the relation between parenting behavior and somatization was not significant. CONCLUSION: Parenting behavior is not univocally related to somatization in adolescents, but the association depends on physiological responses in adolescents.

The distinction of 'psychosomatogenic family types' based on parents' self reported questionnaire information: a cluster analysis.

The theory of 'psychosomatogenic family types' is often used in treatment of somatizing adolescents. This study investigated the validity of distinguishing 'psychosomatogenic family types' based on parents' self-reported family features. The study included a Flemish general population sample of 12-year olds (n = 1428). We performed cluster analysis on 3 variables concerning parents' self-reported problems in family functioning. The distinguished clusters were examined for differences in marital problems, parental emotional problems, professional help for family members, demographics, and adolescents' somatization. Results showed the existence of 5 family types: 'chaotic family functioning,' 'average amount of family functioning problems,' 'few family functioning problems,' 'high amount of support and communication problems,' and 'high amount of sense of security problems' clusters. Membership of the 'chaotic family functioning' and 'average amount of family functioning problems' cluster was significantly associated with higher levels of somatization, compared with 'few family functioning problems' cluster membership. Among additional variables, only marital and parental emotional problems distinguished somatization relevant from non relevant clusters: parents in 'average amount of family functioning problems' and 'chaotic family functioning' clusters reported higher problems. The data showed that 'apparently perfect' or 'enmeshed' patterns of family functioning may not be assessed by means of parent report as adopted in this study. In addition, not only adolescents from 'extreme' types of family functioning may suffer from somatization. Further, professionals should be careful assuming that families in which parents report average to high amounts of family functioning problems also show different demographic characteristics.

Enumeration of small and large numerosities in adolescents with mathematical learning disorders.

The accuracy and speed in an enumeration task were investigated in adolescents with typical and atypically poor development of arithmetic skills. The number naming performances on small and large non-symbolic numerosities of 18 adolescents with mathematical learning disorders (MLD) and 28 typically achieving age-matched (TA) adolescents were compared. A mixed logistic regression model showed that adolescents with MLD were not significantly less accurate on numbers within the subitizing range than control peers. Moreover, no significant differences in reaction times were found between both groups. Nevertheless, we found that within the control group adolescents with higher ability tended to respond faster when taking into account the whole range (1-9) of numerosities. This correlation was much weaker in the MLD group. When looking more closely at the data, however, it became clear that the correlation between accuracy and speed within the control group differed in direction dependent on the range (subitizing or counting) of the numerosities. As such, our findings did not support a limited capacity of subitizing in MLD. However, the data stressed a different correlation between speed and accuracy for both groups of adolescents and a different behavioral pattern depending on the numerosity range as well. Implications for the understanding and approach of MLD are considered.
