Associations Between Father Temperament, Character, Rearing, Psychopathology and Child Temperament in Children Aged 3-6 Years

Interplay of paternal caregiving and screen use habits on early childhood development and children's tantrums

BACKGROUND

This study aims to examine the association for paternal care and father-child screen use with early childhood development and children's temper tantrums.

METHOD

Study file included questions about paternal characteristics, child care, father-child screen habits, and utilized the UNICEF Early Childhood Development Index (ECDI). Factors influencing ECDI-on-track status and children's responses when screen use was restricted were investigated with Chi-square test and multiple logistic regression.

RESULTS

The study included 464 fathers having children aged 3-4 years. The findings showed that 89.7% of the children were on track in three out of the four ECDI subgroups. When screen use was restricted, 55.6% of the children engaged in another activity, while 44.4% reacted by crying. Multiple logistic regression analysis revealed that the father's education level, the child's age and gender, the starting age for screen usage, the child's reaction to screen restriction, and having three or more books were associated with ECDI. Furthermore, the child's reaction to screen restriction was related to the child's and father's screen time, the presence of three or more books, the adequacy of care, and being on track in the literacy-numeracy ECDI subgroup.

CONCLUSION

Screen usage habits significantly impact early childhood development and children's reactions to screen restrictions. These findings underscore the importance of educating fathers about the effects of their own and their child's media habits, the quality of fatherly caregiving, and the presence of books in fostering positive child development.

A multifactorial model for the etiology of neuropsychiatric disorders: the role of advanced paternal age

Mental or neuropsychiatric disorders are widespread within our societies affecting one in every four people in the world. Very often the onset of a mental disorder (MD) occurs in early childhood and substantially reduces the quality of later life. Although the global burden of MDs is rising, mental health care is still suboptimal, partly due to insufficient understanding of the processes of disease development. New insights are needed to respond to this worldwide health problem. Next to the growing burden of MDs, there is a tendency to postpone pregnancy for various economic and practical reasons. In this review, we describe the current knowledge on the potential effect from advanced paternal age (APA) on development of autism spectrum disorder, schizophrenia, attention-deficit/hyperactivity disorder, bipolar disorder, obsessive-compulsive disorder, and Tourette syndrome. Although literature did not clearly define an age cut-off for APA, we here present a comprehensive multifactorial model for the development of MDs, including the role of aging, de novo mutations, epigenetic mechanisms, psychosocial environment, and selection into late fatherhood. Our model is part of the Paternal Origins of Health and Disease paradigm and may serve as a foundation for future epidemiological research designs. This blueprint will increase the understanding of the etiology of MDs and can be used as a practical guide for clinicians favoring early detection and developing a tailored treatment plan. Ultimately, this will help health policy practitioners to prevent the development of MDs and to inform health-care workers and the community about disease determinants. Better knowledge of the proportion of all risk factors, their interactions, and their role in the development of MDs will lead to an optimization of mental health care and management. IMPACT: We design a model of causation for MDs, integrating male aging, (epi)genetics, and environmental influences. It adds new insights into the current knowledge about associations between APA and MDs. In clinical practice, this comprehensive model may be helpful in early diagnosis and in treatment adopting a personal approach. It may help in identifying the proximate cause on an individual level or in a specific subpopulation. Besides the opportunity to measure the attributed proportions of risk factors, this model may be used as a blueprint to design prevention strategies for public health purposes.

Parental genetic contributions to neonatal temperament in a nonhuman primate (Macaca mulatta) model

Temperament is an individual's nature and is widely believed to have a heritable foundation. Few studies, however, have evaluated paternal and maternal contributions to the triadic dimensions of temperament. Rhesus monkeys are widely utilized to model genetic contributions to human development due to their close genetic-relatedness and common temperament structure, providing a powerful translational model for investigating paternal and maternal genetic influences on temperament. The temperament of rhesus monkey infants born to 19 different sires and 50 different dams was assessed during the first month of life by comparing the temperament of paternal or maternal half-siblings reared with their mothers in species-normative conditions or reared in a neonatal nursery. Factor scores from three dimensions of temperament were obtained (Orienting/Regulation, Negative Affectivity, and Surgency/Extraversion) and ANOVAs were used to assess genetic effects. For paternal half-siblings, results showed a statistically significant paternal contribution to Orienting/Regulation, Negative Affectivity, and Surgency/Extraversion factor scores. For maternal half-siblings, results showed a statistically significant contribution to Orienting/Regulation factor scores. When parsed by early rearing condition, results showed a paternal contribution Orienting/Regulation, Negative Affectivity, and Surgency/Extraversion scores for paternal half-siblings reared in the neonatal nursery, while there was only a paternal contribution to Surgency/Extraversion for paternal half-siblings reared by their mothers. There was only a maternal contribution to Orienting/Regulation for maternal half-siblings reared by their mothers. These results show that paternal and maternal contributions to temperament vary by environmental context, and that mothers may environmentally buffer their infants from paternal contributions to their temperament.
