We assessed parents' testosterone reactivity to the Strange Situation Procedure (SSP), a moderately stressful parent-infant interaction task that pulls for parental nurturance and caregiving behavior. Parents (146 mothers, 154 fathers) interacted with their 1-year-old infants, and saliva samples were obtained pre- and post-task to assess changes in testosterone. We examined whether testosterone reactivity differed between mothers and fathers, the extent to which parents' characteristic approaches to closeness (i.e., adult attachment orientation) contributed to testosterone changes, and whether any influences of adult attachment orientation were independent of more general personality characteristics (i.e., the Big Five personality dimensions). Results revealed that mothers and fathers showed comparable declines in testosterone during the SSP, and that these declines were attenuated among fathers with a more avoidant attachment orientation (i.e., those less comfortable with closeness). Associations between fathers' avoidance and testosterone reactivity were statistically independent of broader personality traits. Our findings provide some of the first evidence for short-term changes in both mothers' and fathers' testosterone in contexts that pull for nurturance. Moreover, these findings demonstrate that individual differences in adult attachment may play an important role in understanding such changes. We discuss possible explanations for gender differences in associations between adult attachment and parents' testosterone reactivity, and the extent to which testosterone reactivity might be sensitive to changes in context for mothers versus fathers., (Copyright © 2019 Elsevier Inc.

Objectives: Research on the psychobiology of partnering and fathering has focused on testosterone (T), oxytocin, and prolactin (PRL) as mechanisms that potentially mediate life history trade-offs related to those roles. Less is known about other hormones that might be responsive to life history transitions and implicated in fathering, such as estradiol (E2). We examined how E2 changed during the transition to marriage and fatherhood, its correlation with fathers' caregiving, and its joint within-individual production with other hormones (T, PRL)., Methods: Data were collected from a total of 913 Filipino men (aged 25.9 years ± 0.3 SD at follow-up) enrolled in a longitudinal cohort study. Morning saliva samples collected at baseline (2005) and follow-up (2009) were assayed for T and E2 (n = 329), dried blood spots from baseline were assayed for PRL. Fathers reported on caregiving in 2009., Results: When compared with men who remained single non-fathers over the study period, men who became married residential fathers experienced larger declines in E2. This effect was non-significant when we controlled for longitudinal changes in T. E2 was not significantly related to fathers' caregiving, controlling for T. In cross-sectional analyses for PRL, T, and E2, married residential fathers exhibited within-individual profiles of reduced T and elevated PRL, whereas single non-fathers exhibited the opposite profile of elevated T and reduced PRL., Conclusions: Our findings point to the need for future research to consider the mutually regulatory dynamics and/or combinatorial implications of multiple physiological axes acting within individuals to underpin life history trade-offs and behavioral strategies., (© 2018 Wiley Periodicals, Inc.)

Human paternal behavior is multidimensional, and extant research has yet to delineate how hormone patterns may be related to different dimensions of fathering. Further, although studies vary in their measurement of hormones (i.e., basal or reactivity), it remains unclear whether basal and/or reactivity measures are predictive of different aspects of men's parenting. We examined whether men's testosterone and cortisol predicted fathers' involvement in childcare and play with infants and whether fathers' testosterone and cortisol changed during fathers' first interaction with their newborn. Participants were 298 fathers whose partners gave birth in a UNICEF-designated "baby-friendly" hospital, which encourages fathers to hold their newborns 1 h after birth, after mothers engage in skin-to-skin holding. Salivary testosterone and cortisol were measured before and after fathers' first holding of their newborns. Basal and short-term changes in cortisol and testosterone were analyzed. Fathers were contacted 2-4 months following discharge to complete questionnaires about childcare involvement. Fathers' cortisol decreased during the time they held their newborns on the birthing unit. Fathers' basal testosterone in the immediate postnatal period predicted their greater involvement in childcare. Both basal and reactivity cortisol predicted fathers' greater involvement in childcare and play. Results suggest that reduced basal testosterone is linked with enhanced paternal indirect and direct parenting effort months later, and that higher basal cortisol and increases in cortisol in response to newborn interaction are predictive of greater paternal involvement in childcare and play, also months later. Findings are discussed in the context of predominating theoretical models on parental neuroendocrinology., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Early life cues of environmental harshness and unpredictability have been hypothesized to influence within-species variation in the timing of life history transitions and the dynamics of reproductive strategies, such as investments in mating and parenting. It is also believed that adolesence is an influential developmental period for male reproductive strategies, with those who achieve greater social and sexual success during that period maintaining faster life history strategies into adulthood. If correct, such early life and post-pubertal experiences could also help shape the psychobiological pathways that mediate reproductive strategies, including the well documented physiological shifts that occur when some men become parents. Drawing on a large sample of Filipino men (n=417), we evaluate whether men who experienced cues of harshness or unpredictability in childhood or have earlier ages at sexual debut have elevated testosterone (T) as fathers. We also test whether males who experienced a combination of early life experiences of harshness or unpredictability and had earlier ages of sexual debut during adolescence had the most elevated T as fathers. We found that fathers who experienced early life harshness and who engaged in sex at an earlier age had elevated waking T. Among men transitioning to fatherhood across the 4.5-year follow-up period of this study, those who experienced unpredictability and who engaged in sex at an earlier age showed attenuated declines in waking T between baseline and follow-up. Complementing these findings, we found that fathers who first engaged in sex at later ages had greater acute declines in T when they played with their toddlers. We suggest that these patterns could reflect programming effects of sociosexual experiences during the years following the marked biological transitions that accompany puberty, which occur along with the better-studied effects of earlier life exposures to stressors. Overall, our results support the hypothesis that early life circumstances and social and sexual experiences, from early life to young adulthood, help calibrate physiological axes as key mechanisms coordinating dynamic life history strategies., (Copyright © 2018.

This study examined changes in coparenting after the birth of a second child. Mothers and fathers from 241 2-parent families reported on their spouses' coparenting cooperation and conflict with their firstborn children before (prenatal) and 4 months after the birth of a second child. Parents completed prenatal questionnaires on their gender-role attitudes, marital satisfaction, and firstborn children's temperamental characteristics. Parents also reported on their second-born infants' temperaments at 1 month of age. Coparenting conflict increased across the transition, and cooperation decreased. Couples in which fathers reported greater marital satisfaction were more cooperative 4 months after the second birth. Firstborns' difficult temperaments contributed to less cooperative coparenting by both parents. When mothers had more traditional gender-role beliefs, fathers engaged in more conflictual coparenting behavior, and when fathers had more traditional gender-role beliefs, mothers engaged in more conflictual coparenting behavior. Mothers, but not fathers, engaged in more coparenting conflict regarding the firstborn when both the firstborn and infant sibling had difficult temperaments.

Few fMRI studies have investigated the brain-behavioral basis of parenting in human fathers. Ten fathers were videotaped and gave salivary testosterone samples while interacting with their 2-4 months old infants, and viewed video clips of their own infant and an unfamiliar age-, ethnicity- and sex-matched other infant during an fMRI protocol. Infant stimuli activated a network of prefrontal and subcortical brain regions. Furthermore, a subset of these regions activated significantly more to own (OWN) than other (OTHER) infants. Finally, neural responses to OWN versus OTHER were linked with paternal sensitivity, paternal reciprocity, and testosterone. In sum, our results provide a novel perspective on the links between brain, behavior, and hormones in fathers., (Copyright © 2012 Elsevier B.V. All rights reserved.)

Our study investigated the contribution of caregiving identity in the association between marital satisfaction and coparenting quality in fathers and mothers from a sample of opposite-sex couples of young children living in different areas of the United States. We conducted nested Actor-Partner Interdependence Models and moderation tests to examine potential differences between fathers and mothers in associations between marital satisfaction and coparenting quality, as well as the role of caregiving identity in the association. Results confirmed gender differences in the association between marital satisfaction and coparenting. Both mother's and father's caregiving identity interacted with their own marital satisfaction, but these interactions only impacted the coparenting quality reported by mothers. Additionally, caregiving identity in fathers and mothers was associated with the coparenting quality reported by their spouses. Our study highlighted the important role of caregiving identity in understanding the relation between marital satisfaction and coparenting quality in the intrafamilial processes of couples with young children.

Objective: We tested whether cognitive reappraisal and coparenting quality moderate marital to parent–child spillover in mothers and fathers. Background: The influence of marital relationship quality on parent–child relationships, referred to as the spillover effect, is well documented. Factors that may attenuate the occurrence of spillover, however, remain unclear. Cognitive reappraisal, an emotion regulation strategy that promotes the reframing of emotional situations as neutral or positive, and coparenting—the intermediate subsystem between the marital and parent–child relationships—may buffer the effects of marital to parent–child spillover. Method: Using daily diary data from mother–father couples (N = 96) of young children (Mage = 3.22 years), we investigated coparenting quality and cognitive reappraisal as moderators of marital and parent–child spillover within and between days. Results: Dyadic multilevel models revealed within‐day spillover of marital emotional climate and parent–child emotional climate for both mothers and fathers. Whereas cognitive reappraisal moderated spillover for fathers, no significant moderators emerged for mothers. Fathers also experienced next‐day associations between marital emotional climate and parent–child emotional climate the following day, whereas mothers did not. Coparenting quality accounted for next‐day associations between fathers' marital emotional climate and parent–child climate. Conclusion: Overall, our results evince that although spillover can be attenuated by both cognitive reappraisal and coparenting quality for fathers, the same is not true for mothers. Implications: These results signify the importance of considering mother and father differences in empirical investigations of spillover effects and processes within the family system, and the clinical implications recommended to marriage and family therapists.

Across vertebrates, testosterone is an important mediator of reproductive trade-offs, shaping how energy and time are devoted to parenting versus mating/competition. Based on early environments, organisms often calibrate adult hormone production to adjust reproductive strategies. For example, favorable early nutrition predicts higher adult male testosterone in humans, and animal models show that developmental social environments can affect adult testosterone. In humans, fathers' testosterone often declines with caregiving, yet these patterns vary within and across populations. This may partially trace to early social environments, including caregiving styles and family relationships, which could have formative effects on testosterone production and parenting behaviors. Using data from a multidecade study in the Philippines (n = 966), we tested whether sons' developmental experiences with their fathers predicted their adult testosterone profiles, including after they became fathers themselves. Sons had lower testosterone as parents if their own fathers lived with them and were involved in childcare during adolescence. We also found a contributing role for adolescent father--son relationships: sons had lower waking testosterone, before and after becoming fathers, if they credited their own fathers with their upbringing and resided with them as adolescents. These findings were not accounted for by the sons' own parenting and partnering behaviors, which could influence their testosterone. These effects were limited to adolescence: sons' infancy or childhood experiences did not predict their testosterone as fathers. Our findings link adolescent family experiences to adult testosterone, pointing to a potential pathway related to the intergenerational transmission of biological and behavioral components of reproductive strategies.

• Attachment configurations (security to both mothers and fathers) measured in infancy predict effortful control, compliance, and defiance levels later in toddlerhood. • Infants with secure attachment to only fathers have lower levels of effortful control and higher defiance in toddlerhood than all other attachment configurations. • Infants with secure attachment to only mothers have higher levels of compliance than all other attachment configurations. Infant-parent attachment has been theoretically proposed to serve a key regulatory function for children's emotion, cognition, and behavior, with secure attachment leading to more favorable outcomes, but much of the research supporting this claim has been conducted solely on infant-mother dyads. While research on infant-father attachment has gained traction, studies including fathers often examine their contributions as independent from mothers, which may overlook the interacting influence of multiple attachment relationships on child development. Here, we use a new approach in which we consider infant attachment to both mothers and fathers as a configuration. This study examined whether infant attachment configurations to both mothers and fathers predicted effortful control, compliance, and defiance during toddlerhood. Using data from a longitudinal study on socio-emotional development, 117 infants participated in the Strange Situation, first with their mothers at 12 months, and then again with their fathers at 14 months to assess attachment. When toddlers were 20 months of age, mothers completed a questionnaire assessing toddlers' effortful control, and toddlers were video recorded with their mothers and fathers in a gratification delay and clean-up task during a laboratory visit. Toddlers' compliance and defiance towards parents were coded. Using linear mixed models, attachment configuration in infancy significantly distinguished effortful control, compliance, and defiance in toddlerhood. Infants with a secure attachment only to fathers had significantly lower effortful control and higher defiance at 20 months than the other 3 attachment configurations. In contrast, infants with a secure attachment to mothers were significantly more compliant than infants without a secure attachment to mothers. Our findings provide evidence that when analyzed from a family systems perspective, attachment security (and insecurity) to mothers and fathers may be functionally distinct for children's developing socio-emotional competence.

Conflict and tension in the couple relationship transfers to the parent–child relationship, amplifying the stress parents experience while parenting young children. Pinpointing moderating and individual‐level factors that exist in this spillover process may identify both couple and individual areas where spillover might be mitigated. This study used a within‐couple approach to test for gender differences in marital‐to‐parenting spillover and to examine the moderating roles of gender, parental identity, and the emotion regulation strategy cognitive reappraisal in the linkages between marital–parenting spillover. From a larger study of parenting experiences, 96 mother–father couples of young children (mean age = 3.22 years) reported on measures of marital satisfaction, cognitive reappraisal, parenting identity, and parenting stress. Using path model comparisons, we found more similarities than differences between mothers and fathers and, contrary to the hypothesis, that mothers experienced greater spillover between marital satisfaction and parental distress than fathers. Results differed between outcome measures, suggesting that parents experience more spillover from marital satisfaction to parenting in the context of parental distress than in dysfunctional interactions with their child. Importantly, we found that higher parental identity strengthened marital‐to‐parenting spillover for mothers in contrast to expectations based on theoretical assumptions, whereas cognitive reappraisal weakened marital‐to‐parenting spillover, supporting the broader emotion regulation literature. These results signify the importance of situating the marriage to parenting transfer in the context of affective experiences and intensified parenting expectations, wherein flexibility in role identity may help alleviate parenting stress.

Attachment security is theorized to shape stress reactivity, but extant work has failed to find consistent links between attachment security to mothers and infant cortisol reactivity. We examined family configurations of infant-mother and infant-father attachment security in relation to infant cortisol reactivity. One-year old infants (N = 180) participated in the Strange Situation with mothers and fathers in two counterbalanced lab visits, one month apart (12 and 13 months). Infants with secure attachments only to their fathers and not their mothers had higher cortisol levels than infants with a secure attachment to mother and also exhibited a blunted cortisol response (high at baseline and then a decrease after stress). Results suggest that a secure attachment to father may not be enough to reduce infant stress reactivity when the infant-mother attachment is insecure, and future research is needed to uncover the family dynamics that underlie different family configurations of attachment security.

TV content has been documented to portray a limited range of gender roles, and to frequently depict fathers as incompetent parents. Accordingly, this study explored whether first-time expectant parents' beliefs about gendered family roles and the importance of fathers to child development were related to their TV use. Participants were 201 individuals (122 women, 79 men) from across the United States expecting their first biological child in a cohabiting heterosexual relationship. Participants completed an online survey assessing weekly TV exposure, exposure to TV programs featuring fathers, perceived realism of TV, use of TV to learn about the world, and beliefs about both fathers' importance to child development and family gender roles. Zero-order correlations indicated that increased exposure to TV in general and to programs featuring fathers, perceived realism, and stronger learning motives were each linked to less egalitarian gender role beliefs in both women and men. Among women, heavier exposure to TV in general and to programs featuring fathers, and stronger learning motives were each correlated with weaker beliefs that fathers were important to child development. Multiple regression analyses, however, indicated that attributing more realism to TV content uniquely predicted more traditional gendered family role beliefs and beliefs that fathers are less important to child development across the whole sample. Even among men with low perceived realism, greater exposure to TV fathers was linked with weaker beliefs that fathers were important to child development. First-time expectant fathers may be especially vulnerable to media messages about father roles. [ABSTRACT FROM AUTHOR]

While parenting children with difficult behaviors can intensify stress within the entire family system, families may lean on other familial relationships to mitigate that stress. The coparenting relationship is known to play a key role within the family system for child outcomes and familial interactions, but it is not clear whether it eases the stress and challenge of raising a difficult child, nor how that plays out differently for mothers versus fathers. Ninety‐six couples (89.7% married) parenting young children (Mean age = 3.22 years) were included in this study. Using cross‐sectional and aggregated daily response data, actor–partner interdependence models were used to examine how mothers' and fathers' perceived coparenting support lessened or intensified parenting stress and/or daily problems with their child/children—for themselves or their parenting partner. We found that greater coparenting support reported by mothers coincided with stronger links between the mother's report of child difficulty and daily problems encountered by both mothers and fathers. In contrast, when fathers reported greater coparenting support, the intensity between reported child difficulty and daily problems decreased for mothers, and fathers reported lower parenting stress. Coparenting support also moderated associations between parents' perception of child difficulty and daily problems with their children. These results suggest that mothers incur heightened coparenting support from fathers when experiencing more difficult child behavior and that coparenting support experienced by fathers may alleviate parenting challenges for mothers. These findings further contribute to the literature by emphasizing distinct differences between mothers and fathers in coparenting associations within the family system. [ABSTRACT FROM AUTHOR]
