Fathering behavior, attachment, and engagement in childcare predict testosterone and cortisol.

The present study examined testosterone (T) and cortisol (Cort) in fathers engaged with caregiving. We collected saliva samples in the mornings and evenings of two consecutive days in 150 fathers of 1- to 5-year-old children. Fathers completed questionnaires on socioeconomic status, family structure and life, sleep characteristics and body mass index (BMI), and reported on their engagement in childcare. Fathers used smartphone-based experience sampling throughout 1 week to sample ongoing activities with their children, including times of supervision, joint play, rough-and-tumble play, and cuddling episodes. External observers rated father-child attachment during a home visit. We began by testing for widely characterized covariates of T and excluded seasonal variations and known predictors associated with lowered T, such as older fathers and those with multiple and young children, lower BMI, shorter sleep duration, and sexual activity before sampling. Most interestingly, however, fathers' engagement in childcare and attachment to the child appeared more pronounced the greater the diurnal decline in T. Cuddling predicted a similar negative association, whereas joint play and rough-and-tumble play (RTP) showed enhancing effects on declining T. Interestingly, all fathering behaviors (except RTP) were positively related to lower Cort. In contrast, supervision was ineffective on both Cort and T.

The terrible twos: How children cope with frustration and tantrums and the effect of maternal and paternal behaviors.

Experimental Frustration Procedures with 158 children (15-39 months) of two-parent families were conducted, with each parent separately involved. We examined diverse characteristics of children's frustration and focused on specific behaviors of how children coped and parents supported them. In addition, external observers measured child attachment security (via Attachment Q Sort) toward the mother and the father during two home visits. Children with high attachment security became frustrated later and for a shorter time, and fathers, as compared to mothers, relieved these frustration patterns and reduced them. Although 22.2% children exhibited intense frustration responses up to tantrums, levels remained unaffected by child gender, but decreased with child age. Time-lag analyses revealed that children's self-comforting behaviors reduced frustration responses only by around 20%, but self-distracting (in younger children) and pretend-playing (in older children) by around 50% and 70%. Of the parent behaviors, demonstrating reduced children's frustration by up to 40% whereas distracting and reframing by around 60% (mothers) and 80% (fathers). In general, mothers tended to protect the child from distress, whereas fathers assisted the child in coping with frustration. However, if mothers soothed and fathers encouraged, children's frustration intensified.

How fathers' attachment security and education contribute to early child language skills above and beyond mothers: parent-child conversation under scrutiny.

Attachment (AQS) of 100 children aged 12 to 24 months was observed, with more than half of the fathers (and mothers) representing higher social status. Children's language comprehension and production were measured using the Bayley Scales for receptive (RLS) and expressive language skills (ELS). Spontaneous book reading conversations in father-child and mother-child dyads were coded from videotapes, capturing five modes of conversation derived from research on dialogic reading. Path modelling examined the association of these modes on children's RLS and ELS in concurrence with parental attachment and education. First time, significant effects of father-child attachment security on children's RLS were revealed (and confirmed for mother-child dyads). Fathers' impact on child language skills could be further explained through modes which inquire and imitate child responses which were related to RLS and ELS, respectively. Although mothers' modes of conversation were associated with the mother-child attachment relationship, the father-child conversations were not so but instead were associated with the father's educational background.
