Practicable strategies parents can apply in their daily routine to successfully implement the 50/50-split-model of paid work, childcare, and housework: a qualitative content analysis.

BACKGROUND: Many young couples are planning to share paid work, childcare, and housework equally between each other. But implementing such a 50/50-split-model is difficult and parents often return to traditional gender role distributions after the birth of a child. This return has potential negative effects on mental health, physical health, and relationship satisfaction. Therefore, this study aims to find practicable strategies on a behavioral-level which new parents can apply in their daily routine to successfully implement the 50/50-split-model if they wish to do so. METHODS: This qualitative study, DREAMTALK, is part of the multi-method, prospective Dresden Study on Parenting, Work, and Mental Health (DREAM). For DREAMTALK, N = 25 parents implementing a 50/50-split-model were selected based on quantitative data regarding time use, which participants had provided in questionnaires. In DREAMTALK, problem-centered interviews were conducted with the selected sample at 17 months postpartum. Those were analyzed via qualitative content analysis, which is systematic, rule-guided, and based on the criteria of validity and reliability. RESULTS: The qualitative content analysis revealed a catalog of 38 practicable strategies to manage daily routine, which can help parents to successfully implement a 50/50-split-model. Individual participants used 23 success strategies on average. Examples include having a regular coordination appointment with the other parent, planning foresightedly, flexibility, reducing cleaning, optimization of routes, or moderate split-shift parenting. Some of these strategies seem opposing, e.g., planning foresightedly, and at the same time, meeting unpredicted changes with flexibility. Those seemingly opposing strategies were well balanced by the participants, which was an additional strategy. CONCLUSIONS: Parents can use the success strategies relatively independently of external circumstances. This behavioral perspective extends prior theories, which have focused on explaining unequal gender role distributions with external circumstances. A behavioral perspective can be a gateway to assist more parents to pioneer in implementing the 50/50-split-model, which might in turn lead to a healthier and more satisfied public population.

The impact of mode of delivery on parent-infant-bonding and the mediating role of birth experience: a comparison of mothers and fathers within the longitudinal cohort study DREAM.

BACKGROUND: The association between mode of delivery (MOD) and parent-infant-bonding has only been studied in mothers and findings have been inconclusive. The aim of this study was to prospectively investigate how MOD relates to postpartum parent-infant-bonding in both mothers and fathers and whether these associations are mediated by birth experience. METHODS: This study is part of the prospective cohort study "Dresden Study on Parenting, Work, and Mental Health" (DREAM). Our sample comprised N = 1,780 participants who completed quantitative questionnaires during pregnancy as well as 8 weeks and 14 months postpartum. MOD was dummy coded, contrasting spontaneous vaginal delivery against vaginal delivery induced by drugs, operative vaginal delivery, planned, and unplanned cesarean section. Parent-infant bonding and birth experience were assessed using validated scales. A moderated mediation analysis based on ordinary least square (OLS) regression and bootstrapped estimates was conducted, considering relevant confounding variables. RESULTS: Compared to spontaneous vaginal delivery, all categories of MOD predicted more negative birth experiences in both parents. A more positive birth experience predicted stronger parent-infant-bonding at 8 weeks, but not at 14 months postpartum. Mothers who delivered via cesarean section (planned or unplanned) reported stronger parent-infant-bonding at 8 weeks and 14 months postpartum. In fathers, only unplanned cesarean section was associated with stronger parent-infant-bonding at 8 weeks postpartum. At 8 weeks postpartum, birth experience mediated the association between a vaginal delivery induced by drugs and a planned cesarean section and mother-infant-bonding and between a vaginal delivery induced by drugs, an operative vaginal delivery, and planned cesarean section and father-infant-bonding. At 14 months postpartum, birth experience mediated the association between a vaginal delivery induced by drugs, operative vaginal delivery, and planned cesarean section and parent-infant-bonding in both parents. CONCLUSIONS: The results emphasize the importance of the birth experience for parent-infant-bonding in both mothers and fathers. Further research should address the mechanisms by which parents with an unplanned cesarean section establish stronger parent-infant-bonding compared to parents whose baby was delivered via spontaneous vaginal delivery, despite their overall more negative birth experiences.

Psychosocial work stress and parent-child bonding during the COVID-19 pandemic: clarifying the role of parental symptoms of depression and aggressiveness.

BACKGROUND: Parental work stress and impaired mental health seem to have intensified during the current COVID-19 pandemic. Both can have a negative impact on parent-child bonding: psychosocial work stress in the course of a spillover effect from work to family and symptoms of impaired mental health as part of a crossover effect from parent to child. This potentially affects the child's development in the long term. METHOD: This cross-sectional study examined the relationship between psychosocial work stress and parent-child bonding during the early COVID-19 pandemic (May-June 2020). Symptoms of depression and aggressiveness were considered as mediators of this relationship. The sample consisted of employees in Eastern Germany (n = 380; 42.9% mothers, 57.1% fathers), aged 24-55 years, with children aged 0-36 months. RESULTS: In the total sample, an association was only found after adjusting for potential confounders, indicating that higher psychosocial work stress is associated with weaker bonding between the parent and child (ß = 0.148, p = .017, 95% CI [0.566, 5.614]). The separate analyses for mothers and fathers did not reveal a statistically significant relationship between psychosocial work stress and parent-child bonding. In the total sample, the higher the psychosocial work stress was, the higher were the parental symptoms of depression (ß = 0.372, p < .001, 95% CI [3.417, 5.696]) and aggressiveness ß = 0.254, p < .001, 95% CI [1.008, 3.208]). The mental health symptoms in turn were related to weaker parent-child bonding (symptoms of depression ß = 0.320, p < .001, 95% CI [0.345, 0.749]; symptoms of aggressiveness ß = 0.394, p < .001, 95% CI [0.697, 1.287]). The results furthermore suggested that parental mental health symptoms mediate the association between psychosocial work stress and parent-child bonding (symptoms of depression, ab = 2.491, 95% CI [1.472, 3.577] and of aggressiveness, ab = 2.091, 95% CI [1.147, 3.279]). The mediation effect was also found in the separate analyses for the mothers and fathers. DISCUSSION: The results of this study during the early COVID-19 pandemic in Germany highlight the importance of prevention as well as intervention measures in relation to psychosocial work stress that may play a debilitating role in the context of family relationships. In addition, the results suggest that both employers and employees should be made aware of the importance of psychosocial work stress, as it can have a negative impact on mental health, which in turn may have a major influence on family relationships.

Mental health of working parents during the COVID-19 pandemic: can resilience buffer the impact of psychosocial work stress on depressive symptoms?

BACKGROUND: The COVID-19 pandemic has confronted working parents with an accumulation of stressors regarding changes in work, family, and social life, putting their mental health at risk. Stressors include altered working conditions such as working from home or changes in working hours as well as the difficulty to reconcile work and childcare due to the closure of childcare facilities. The present study examined the relationship of psychosocial work stress (i.e., work-privacy conflict and effort-reward imbalance at work) and depressive symptoms in working parents and whether this association was moderated by individual resilience. METHODS: Data of the present study (n = 452) were collected in Germany between May and June 2020 as part of the DREAMCORONA study. A subsample of working mothers (n = 191) and fathers (n = 261) completed the subscale for work-privacy conflict (WPC) of the Copenhagen Psychosocial Questionnaire, the Effort-Reward Imbalance (ERI) Questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), and the Edinburgh Postnatal Depression Scale (EPDS). Multiple linear regression analyses including moderation were performed, controlling for gender, working hours per week, and a lifetime history of depression as potential confounders. RESULTS: Both WPC (ß = 0.336, p < .001) and ERI (ß = 0.254, p < .001) were significantly associated with depressive symptoms. Resilience moderated the relationship between ERI and depressive symptoms (ß = - 0.101, p = .018), indicating that higher resilience weakened the relationship. However, this effect was not found regarding the relationship between WPC and depressive symptoms (ß = 0.055, p = .167). CONCLUSIONS: The results highlight the need for measures to reduce psychosocial work stressors such as WPC and ERI during the COVID-19 pandemic on the one hand and to promote resilience on the other hand. The findings partially support the potential protective role of resilience buffering the association between psychosocial stress and mental health in working parents. Longitudinal studies are needed to confirm this effect.

Precarious working conditions and psychosocial work stress act as a risk factor for symptoms of postpartum depression during maternity leave: results from a longitudinal cohort study.

BACKGROUND: The majority of Western women work during their reproductive years, but past research has often neglected the influence of work-related factors on postpartum mental health. Especially postpartum depression (PPD) is an enormous psychological burden for mothers. Therefore, this study aims to investigate the prospective impact of precarious working conditions and psychosocial work stress during pregnancy (such as work-privacy conflict and effort-reward imbalance at the job) on symptoms of maternal PPD. METHODS: In the prospective-longitudinal cohort study DREAM (DResdner Studie zu Elternschaft, Arbeit und Mentaler Gesundheit), N = 587 employed women were questioned about their work during pregnancy and their mental health 8 weeks after delivery. RESULTS: Multiple regression analyses revealed that work-privacy conflict, low reward at work, and precarious working conditions significantly predicted symptoms of PPD, even when controlling for lifetime depression, anxiety, education, parity, and age. CONCLUSION: Our results indicate that psychosocial work stress and precarious working conditions have important implications for maternal peripartum mental health. They might act as prospective risk factors for PPD during the period of maternal leave. Hence, future research should focus on preventative measures targeting work life.

High Dietary Intake of Specific Fatty Acids Increases Risk of Flares in Patients With Ulcerative Colitis in Remission During Treatment With Aminosalicylates.

BACKGROUND & AIMS: Dietary factors may have a significant role in relapse of disease among patients with ulcerative colitis (UC). However, the relationship between diet and UC is inadequately understood. We analyzed data from the diet's role in exacerbations of mesalamine maintenance study to determine whether dietary factors affect the risk of disease flares in patients with UC. METHODS: We performed a prospective, multicenter, observational study of 412 patients, from 25 sites, with UC in remission during monotherapy with an aminosalicylate. Patients completed a validated food frequency questionnaire at enrollment and were followed for 12 months. We analyzed the relationship between diet and disease remission or flare for groups of macronutrients and micronutrients, and food groups previously associated with an increased risk of flare. RESULTS: Forty-five patients (11%) had a UC relapse within 1 year of study enrollment. When analyzed in tertiles, increasing intake of multiple fatty acids was associated with increasing odds of relapse. In multivariable logistic regression analysis, only myristic acid (odds ratio, 3.01; 95% confidence interval, 1.17-7.74) maintained this dose-response relationship. Other foods previously implicated in flares of UC, such as processed meat, alcohol, and foods high in sulfur, were not associated with an increased risk of flare. CONCLUSIONS: In a prospective study of more than 400 patients with UC undergoing treatment with aminosalicylates, we associated high dietary intake of specific fatty acids, including myristic acid (commonly found in palm oil, coconut oil, and dairy fats) with an increased risk of flare. These findings can help design interventional studies to evaluate dietary factors in UC.

Does parental mental health mediate the association between parents' perceived stress and parent-infant bonding during the early COVID-19 pandemic?

BACKGROUND: The spread of the COVID-19 virus was declared a pandemic in March 2020. New restrictions such as 'lockdowns' and 'social distancing' created challenges for individuals' work-life balance, financial situation, family life, and physical and mental health. The global population's stress levels rose in response to these changes, leading to a widespread deterioration of mental health. One group particularly affected was parents of infants and very young children. Poor parental mental health may disrupt parent-infant bonding, with negative consequences for infant well-being and development. AIMS: To consider parent-infant bonding in relation to parents' perceived stress and psychological distress during the first lockdown, and to examine whether associations of stress with parent-infant bonding were mediated by parental mental health. METHODS: DREAMCORONA (n = 738: 471 mothers and 267 partners) is a sub-study of the prospective German cohort study 'DREAM'. The SPSS modelling tool PROCESS was used to assess whether parental mental health mediated the relationship between parents' perceived stress response to the COVID-19 pandemic and parent-infant bonding, while controlling for covariates. RESULTS: Higher levels of parental stress were strongly associated with higher levels of depression, anxiety, and aggression symptoms for both parents. In addition, there was a significant relationship between parents' self-reported stress levels and parent-infant bonding. This relationship was mediated by symptoms of depression and anxiety for fathers and by symptoms of anger-hostility for both parents. CONCLUSION: Increased parental stress during the early pandemic was associated with poorer parent-infant bonding. This has important implications for the management of any future public health crises.

Going through it together: Dyadic associations between parents' birth experience, relationship satisfaction, and mental health.

BACKGROUND: Previous research suggests that a negative birth experience is associated with symptoms of postpartum depression and anxiety in mothers and partners. However, this has mostly been investigated within the first year postpartum and research on the long-term effects is lacking. Additionally, the role of relationship satisfaction and the interdependence between parents have not been considered so far. METHODS: Couples (N = 1992) completed questionnaires on their birth experience, relationship satisfaction, and symptoms of depression and anxiety at two months, 14 months, and two years after birth, respectively. RESULTS: Actor-Partner Interdependence Mediation Models indicated no partner effects, but several significant actor and indirect effects. A more positive birth experience was associated with higher relationship satisfaction and less depression and anxiety symptoms for both parents. Higher relationship satisfaction was in turn associated with less depression (mothers and partners) and anxiety symptoms (mothers). The association between birth experience and depression symptoms was partially mediated by relationship satisfaction for mothers and partners, while the association between birth experience and anxiety symptoms was partially mediated by relationship satisfaction only for mothers. LIMITATIONS: Due to the highly educated, very healthy sample with low levels of depression and anxiety as well as high relationship satisfaction, results cannot be generalized to less privileged parents. Moreover, all effects were very small. CONCLUSIONS: Results highlight the importance of a positive birth experience for parents' relationship satisfaction and mental health. Negative birth experiences need to be avoided to prevent a negative impact on the whole family.

Association between systemic medication use and severity of dry eye signs and symptoms in the DRy eye assessment and management (DREAM) study.

PURPOSE: Some systemic medications are reported to be associated with dry eye disease (DED), yet their associations with the severity of DED signs and symptoms are not well studied. To evaluate these associations, we performed a secondary analysis of data from the DRy Eye Assessment and Management (DREAM) Study. METHODS: Participants (N = 535) were assessed for DED signs using tear break-up time (TBUT), Schirmer testing, corneal fluorescein staining, conjunctival lissamine green staining, meibomian gland dysfunction (MGD), and tear osmolarity and DED symptoms using the Ocular Surface Disease Index (OSDI). We derived a composite signs severity score from the 6 DED signs and categorized participant-reported systemic medications into antidepressants, antihistamines, aspirin, corticosteroids, diuretics, nonsteroidal anti-inflammatory drugs, proton pump inhibitors, statins, vitamin D3, and medications for diabetes mellitus, hypertension, hypothyroidism, migraine, and seizure. Generalized linear models were used to compare DED symptom and sign scores between medication users and non-users, with adjustment for factors associated with DED severity. RESULTS: Compared to non-users, antihistamine users had lower TBUT (p = 0.01) and higher OSDI score (p = 0.02); aspirin users had lower TBUT (p = 0.02); corticosteroid users had lower TBUT (p = 0.02), lower Schirmer test scores (p = 0.03), higher cornea fluorescein staining (p = 0.01), higher composite severity score (p = 0.01), and higher OSDI score (p = 0.03); seizure medication users had higher composite severity score (p = 0.02); vitamin D3 users had lower TBUT (p = 0.001) and greater MGD (p = 0.03); and diuretic users had less MGD (p = 0.03). CONCLUSIONS: Certain systemic medications may be associated with more severe DED. This may guide prescription practices in patients with DED.

Maternal postpartum depressive symptoms: The predictive role of objective and subjective birth experience and hair glucocorticoids.

BACKGROUND: Having a negative childbirth experience is a known risk-factor for developing postpartum depression (PPD). Alterations of the hypothalamus-pituitary-adrenal (HPA)-axis have been discussed as a potential underlying mechanism. However, research on the association between negative birth experiences and long-term integrated glucocorticoids (GCs) is lacking. This study aimed to examine whether objective and subjective birth experience predicted long-term GCs and PPD symptoms. METHODS: Measures of objective and subjective birth experience, PPD symptoms, and hair strands for the assessment of hair cortisol concentrations (HairF), hair cortisone concentrations (HairE), and HairF/HairE ratio, were provided eight weeks after childbirth by 235 mothers participating in the study DREAMHAIR. RESULTS: A negative objective birth experience predicted a higher HairF/HairE ratio but was not associated with HairF or HairE. The subjective birth experience did not explain additional variance in hair GCs but was a significant predictor for PPD symptoms. A higher HairF/HairE ratio predicted PPD symptoms when controlling for prepartum depressive symptoms and number of lifetime traumatic events. LIMITATIONS: Analyses were based on a relatively homogeneous sample and women reported in general positive birth experiences and low levels of depressive symptoms. Therefore, results should be applied to the broader population with caution. CONCLUSIONS: Our results suggest that negative objective birth experience is associated with an altered HairF/HairE ratio, which in turn, seems to be a promising biomarker to identify women at risk for developing PPD. A negative subjective birth experience may be less critical for alterations of the HPA-axis but remains an essential risk factor for PPD.

The association between maternal symptoms of depression and hair glucocorticoids in infants across the perinatal period.

BACKGROUND: Maternal symptoms of depression constitute an early adversity for infants that is considered to exert its effects via the maternal-placental-fetal neuroendocrine axis. Previous research implicates associations between maternal prenatal symptoms of depression and infants' glucocorticoid (GC) levels shortly after birth. To date, associations have not been investigated in the early postnatal period. The current study aimed to investigate the influence of maternal perinatal symptoms of depression on infants' neonatal and postnatal hair GCs providing a retrospective reflection of integrated cortisol secretion in the intrauterine and early postnatal period, respectively. METHODS: As part of a prospective cohort study, hair samples of infants were taken up to two weeks after delivery (N = 152) and again eight weeks after delivery (N = 165). Liquid chromatography-tandem mass spectrometry was used to determine hair cortisol and cortisone in scalp-near 2-cm hair segments. Maternal symptoms of depression were assessed during pregnancy and eight weeks postnatally based on the Edinburgh Postnatal Depression Scale. RESULTS: Higher maternal prenatal symptoms of depression showed a significant association with higher infants' neonatal hair cortisol, when controlling for confounding variables (i.e., gestational age, mode of delivery, parity, storage time, pregnancy complications). A non-significant trend for this effect was found for the hair cortisol-to-cortisone ratio while no effect occurred for hair cortisone. No association of maternal postnatal symptoms of depression with infants' postnatal hair GCs was observed. Further exploratory analyses revealed no relationship between a change of maternal prenatal to postnatal symptoms of depression with the change from infants' neonatal to postnatal hair GC levels or postnatal hair GCs. CONCLUSION: Our results suggest that maternal prenatal symptoms of depression are associated with dysregulated infants' hair cortisol levels mainly incorporated in the intrauterine period which, in turn, might contribute to increased susceptibility for later diseases. However, no relationship was observed in infants' hair samples additionally reflecting hair GCs of the early postnatal period. Future studies should consider research on associations between maternal symptoms of depression and infants' hair GCs also later in life and take into account additional risk factors with potential impacts on GC secretion during early infancy.

Dyadic analyses on the prospective association between birth experience and parent-child-bonding: The role of postpartum depression, anxiety, and childbirth-related posttraumatic stress disorder.

OBJECTIVE: Negative birth experiences are associated with postpartum mental health difficulties in parents. However, research considering the long-term impact of a negative birth experience on parent-child-bonding and the interdependence between parents is rare. This study aimed to investigate actor as well as partner effects for the association between parents' birth experience and parent-child-bonding and whether this association is mediated by postpartum psychiatric symptoms. METHOD: A community sample of couples (N = 743) completed questionnaires during pregnancy, 2, and 14 months after birth. RESULTS: Applying Actor-Partner Interdependence Mediation Models, structural equation modeling showed that parents' own negative birth experience predicted a poorer bond to their child 14 months postpartum. Compared to mothers, this association was twice as strong for partners and was mediated by symptoms of postpartum depression (mothers and partners), anxiety (partners), and childbirth-related posttraumatic stress disorder (mothers). Negative birth experiences of one parent were not related to the other parent's bonding with the child. CONCLUSION: Results underline the importance of parents' positive birth experience for their postpartum mental health and secure bond to their child. The other parent's birth experience or postpartum mental health does not seem to affect one's own bond to the child in the long term.

Age Associations with Dry Eye Clinical Signs and Symptoms in the Dry Eye Assessment and Management (DREAM) Study.

Purpose: To evaluate how increasing age is associated with dry eye disease (DED) signs and symptoms in the Dry Eye Assessment and Management (DREAM) study. This study was undertaken to better understand how DED signs and symptoms differ across decades of life with goals to help assess detection and treatment of DED. Design: Secondary analysis of the DREAM study. Subjects: One hundred twenty, 140, 185, and 90 participants aged < 50, 50 to 59, 60 to 69, and ≥ 70 years, respectively. Methods: We performed a secondary analysis of data from the DREAM study, a multicenter randomized clinical trial, to evaluate the effect of omega-3 fatty acid supplementation for the treatment of DED. At baseline, 6 months, and 12 months follow-up, participants underwent an assessment of DED symptoms and signs using Ocular Surface Disease Index, Brief Pain Inventory, tear break-up time (TBUT) (in seconds), Schirmer test with anesthesia (mm/5 minutes), conjunctival staining, corneal staining, meibomian gland dysfunction evaluation, and tear osmolarity (mOsm/l). Multivariable generalized linear regression models were used to compare DED symptoms and signs across the 4 age groups among all participants and by sex. Main Outcome Measures: Scores of DED symptoms, individual signs, and composite scores of DED signs. Results: Among 535 patients with DED, increasing age was significantly associated with worse TBUT (P = 0.01), corneal staining (P < 0.001), a composite severity score of DED signs (P = 0.007), and tear osmolarity (P = 0.001). Similar significant differences were found across 4 age groups of 334 women in TBUT, corneal staining score, composite severity score of DED signs, and tear osmolarity (all P < 0.05) but not in men. Conclusion: We found that corneal staining, TBUT, tear osmolarity, and a composite severity score of DED signs were significantly more severe with increasing age in women but not in men; worsening symptoms did not increase with increasing age.

Prospective associations between prepartum physical activity, birth experience, and maternal depressive symptoms in the postpartum period: Insights from the population-based DREAM cohort study.

BACKGROUND: This study aims to examine whether physical activity (PA) before and during pregnancy and birth experience predict incident postpartum depressive (PPD) symptoms. Because PA may increase endurance and feelings of physical control, it may contribute to a positive birth experience and birth experience may mediate the association between PA before and during pregnancy and PPD symptoms. METHODS: The study is part of the prospective-longitudinal cohort study "Dresden Study on Parenting, Work, and Mental Health" (DREAM). Participants were n = 1,254 (expectant) mothers. PA was assessed during pregnancy, birth experience and PPD symptoms 8 weeks postpartum. Multiple regression analyses were performed, including potential confounders. RESULTS: A negative birth experience was linked to PPD symptoms, when controlling for relevant confounders. There was no evidence for a link between PA before and during pregnancy and birth experience or between PA during pregnancy and PPD symptoms. PA at low and at vigorous intensity before pregnancy was associated with PPD symptoms, but not when controlling for confounders. Because PA was not associated with birth experience, no mediation analysis was performed. LIMITATIONS: The current sample was relatively homogenous (i.e., mostly German native speakers, primiparous, highly educated). Birth experience was assessed retrospectively at 8 weeks following birth. CONCLUSIONS: Our results highlight the importance of the birth experience in the development of PPD symptoms. Promoting a positive birth experience represents a promising approach to prevent PPD symptoms. Further research on the association between PA and PPD symptoms is warranted.

The impact of postpartum obsessive-compulsive symptoms on child development and the mediating role of the parent-child relationship: A prospective longitudinal study.

Background: The first 2 years of life are a particularly sensitive period for the parent-child relationship as well as a healthy, age-appropriate child development. Both have been shown to be linked to postpartum depressive and anxiety symptoms, while the role of obsessive-compulsive symptoms, which are also common, is still largely understudied. In addition, fathers have been neglected in this area of research. This study, which includes both mothers and fathers, aims to investigate the longitudinal associations between postpartum obsessive-compulsive symptoms and different domains of child development, as well as the mediating role of the parent-child relationship. Methods: Data were drawn from the prospective longitudinal study DREAM, with 674 mothers and 442 fathers from the general population completing self-report questionnaires at four measurement points. Longitudinal associations between parental postpartum obsessive-compulsive symptoms 8 weeks postpartum, the parent-child relationship 14 months postpartum, and child development 24 months postpartum were investigated using regression and mediation analyses. A number of potential confounding variables were considered, i.e., age, academic degree, postpartum depressive and anxiety symptoms of the parents, preterm birth and temperament of the child, as well as COVID-19 pandemic-driven adversities. Results: When adjusting for confounders, neither maternal nor paternal postpartum obsessive-compulsive symptoms had adverse effects on the respective parent-child relationship and child development. Further, no mediating role of the parent-child relationship between parental postpartum obsessive-compulsive symptoms and child development could be confirmed. Instead, we found that the mother- and father-child relationship were differentially related to specific child developmental domains. For mothers, a poorer mother-child relationship was prospectively related to poorer fine motor development. For fathers, a poorer father-child relationship prospectively predicted a poorer overall development as well as poorer gross motor, fine motor, problem-solving, and personal-social development. Conclusion: Our results suggest that negative effects on the parent-child relationship and child development may only become apparent in full-blown postpartum obsessive-compulsive disorder. Given the differential impact on specific developmental domains, our findings also suggest that it is crucial to consider both parents in clinical practice as well as in future research, rather than focusing only on the mother-child dyad.

Personality and Peripartum Changes in Perceived Social Support: Findings From Two Prospective-Longitudinal Studies in (Expectant) Mothers and Fathers.

OBJECTIVE: The aim of this study was to examine changes in perceived social support from early pregnancy to 2 years postpartum and to test whether these changes (a) differ between mothers and fathers or (b) vary as a function of the Big Five personality traits. BACKGROUND: Higher peripartum social support in (expectant) mothers and fathers has been associated with fewer complications during pregnancy and delivery as well as better parental and offspring health. METHODS: Prospective-longitudinal data from two regional-epidemiological samples from Germany were used: MARI (N = 396, including n = 293 mothers and n = 103 fathers) and DREAM (N = 2,819, including n = 1,689 mothers and n = 1,130 fathers). The Big Five personality traits were assessed during pregnancy in MARI as well as 8 weeks after the anticipated birth date in DREAM with short forms of the Big Five Inventory. Perceived social support was assessed during pregnancy, 4 months postpartum, and 16 months postpartum in MARI as well as during pregnancy, 14 months postpartum, and 2 years postpartum in DREAM using the short version of the Social Support Questionnaire. RESULTS: Multilevel analyses revealed that perceived social support decreased across the peripartum period, and this decrease did not differ between mothers and fathers. More extraverted, emotionally stable, agreeable, conscientious, and open parents perceived higher levels of social support across the peripartum period. The peripartum decrease of perceived social support was smaller in parents who were more extraverted. CONCLUSION: Our findings suggest that especially extraversion plays an important role for high and stable levels of perceived social support across the peripartum period. IMPLICATIONS: Particularly highly introverted parents might profit from targeted social support interventions.

Differential predictors of birth-related posttraumatic stress disorder symptoms in mothers and fathers - A longitudinal cohort study.

BACKGROUND: Evidence on risk factors of birth-related posttraumatic stress disorder (PTSD) symptoms in mothers is increasing, whereas fathers are less examined. This study aims to determine differential predictors of PTSD symptoms in mothers and fathers. METHODS: Data derive from the DREAM study, including 1,146 mothers and 828 fathers. We assessed mental health, work, and sociodemographic factors during pregnancy, pregnancy- and birth-related factors, and birth-related PTSD symptoms using the Impact of Event Scale-Revised 8 weeks postpartum. Structural equation models were estimated to examine associations between predictors and latent factors of PTSD symptoms for mothers and fathers simultaneously. Scaled chi-square difference tests were used to investigate differences between both groups in predictors. RESULTS: Clinically relevant birth-related PTSD symptoms were found in 2.3% of mothers and 0.7% of fathers. Depressive and anxiety symptoms, pregnancy complications, and poorer subjective birth experience predicted PTSD symptoms in both groups. Additionally, lower support during birth and an unplanned cesarean section predicted PTSD symptoms in mothers, whereas lower job satisfaction, higher job burden, being first-time father, lower education, and mothers' lower support during birth were predictors for fathers. We found significant differences between groups regarding job burden during pregnancy, support during birth, and an unplanned cesarean section. LIMITATIONS: Generalization of findings might be limited by self-selection bias and some systematic dropout. CONCLUSIONS: Our results suggest differential predictors of PTSD symptoms in mothers and fathers. For fathers, less examined factors such as work factors may be important. Identifying differential risk factors may lead to customized prevention and treatment offers.

The Impact of Parental Relationship Satisfaction on Infant Development: Results From the Population-Based Cohort Study DREAM.

Extensive literature has shown that interparental conflicts and violence have detrimental effects on children's adjustment in childhood and adolescence. It is not equally well-understood how parental relationship satisfaction impacts infant communicational and personal-social development during the first year of life. This longitudinal study examines (a) the impact of maternal and paternal relationship satisfaction on infant development, (b) whether this prospective association is mediated by parent-infant relationship, and (c) a potential moderating effect of infant gender. Data were derived from the population-based cohort study "Dresden Study on Parenting, Work, and Mental Health" (DREAM) including 1,012 mothers and 676 fathers. Relationship satisfaction and parent-infant relationship were assessed eight weeks postpartum, infant communicational and personal-social development were measured 14 months postpartum. Multiple linear regression, mediation, and moderation analyses were conducted for mothers and fathers separately. It was shown that paternal relationship satisfaction is a significant predictor of infant personal-social development. This prospective association was partially mediated by father-infant relationship. When postnatal depression was included in the analysis, however, father-infant relationship was not a significant mediator. The association in fathers is neither reduced nor increased as a function of infant gender. No similar effects were found in the mothers' sample. Parental relationship satisfaction did not significantly predict infant communicational development in either mothers or fathers. The study findings highlight the importance of paternal relationship satisfaction, father-infant relationship, and postnatal depression for infant personal-social development.

Birth Experience Mediates the Association Between Fear of Childbirth and Mother-Child-Bonding Up to 14 Months Postpartum: Findings From the Prospective Cohort Study DREAM.

OBJECTIVE: To explore the longitudinal associations between prepartum fear of childbirth (FOC), birth experience, and postpartum mother-child-bonding, and the potential mediator role of the birth experience. DESIGN: Women from the prospective cohort study DREAM completed questionnaires during pregnancy, 8 weeks, and 14 months after the birth. PARTICIPANTS: A community sample of n = 645 pregnant women from a large city in Eastern Germany participated in the study. RESULTS: In a regression analysis, FOC predicted negative birth experience (ß = 0.208, p < 0.001) which in turn predicted poorer mother-child-bonding both at 8 weeks (ß = 0.312, p < 0.001) and 14 months postpartum (ß = 0.200, p < 0.001). FOC also predicted mother-child-bonding at 14 months postpartum (ß = 0.098, p < 0.05). Of note, this association was mediated by birth experience both at 8 weeks, indirect effect ab = 0.065, 95% CI [0.036, 0.098], and 14 months postpartum, indirect effect ab = 0.043, 95% CI [0.023, 0.067]. These effects remained stable even when adjusting for potential confounders. KEY CONCLUSIONS: This study suggests that the association between FOC and mother-child-bonding is mediated by birth experience, pointing to the importance of a woman's positive subjective experience. IMPLICATIONS FOR PRACTICE: Findings reveal two targets for peripartum interventions for women at risk for poor mother-child-bonding, namely the implementation of FOC screenings during pregnancy, and birth experience as mediating factor between FOC and mother-child-bonding. Focusing on the mother's subjective birth experience could aid to identify women at risk for impaired bonding who might need additional support.

Paternal Leave and Father-Infant Bonding: Findings From the Population-Based Cohort Study DREAM.

Background: Father-infant bonding is important for child development. Yet, in contrast to mother-infant bonding, little is known about factors that might facilitate father-infant bonding. With new generations of fathers being more involved in childcare, this study aims to examine the impact of paternal leave duration on father-infant bonding, and whether this relation is mediated by the amount of time fathers actively spend on childcare. Methods: Data of n = 637 fathers were derived from the German population-based cohort study "Dresden Study on Parenting, Work, and Mental Health" (DREAM). Mediation analyses were conducted. Duration of paternal leave (predictor), weekly hours spent on childcare (mediator), and father-infant bonding (outcome) were measured at 14 months postpartum. The potential confounders current status of paternal leave, part-time work during paternal leave, duration of solo paternal leave, age, education, and partnership satisfaction were included in a second mediation analysis. Results: Without considering confounders, duration of paternal leave positively predicted father-infant bonding through weekly hours spent on childcare. When adding confounders to the model, this indirect path did not stay significant. Moreover, in the adjusted model and on the direct path duration of paternal leave negatively predicted father-infant bonding. Additionally, partnership satisfaction positively predicted father-infant bonding. Some study variables were significantly associated with the mediator. Longer duration of paternal leave, currently being on paternal leave, younger age, and lower educational level predicted more weekly hours spent on childcare. Conclusions: Duration of paternal leave not being a stable predictor for father-infant bonding suggests that fathers, who do not have the opportunity to take long periods of paternal leave, can still form strong bonds with their infants. Other factors, for example partnership satisfaction, which might represent fathers' underlying capacity to bond, might be more crucial for father-infant bonding. At the same time, results should not be interpreted in a way that father involvement (e.g., paternal leave/time spent) does not matter for children's development. The finding that longer duration of paternal leave increases weekly hours spent on childcare supports the idea that facilitating father involvement can be achieved by paternal leave incentives such as non-transferable father months.
