= Father Absence = Parental separation may affect the child’s development. Early parental divorce (during primary school) has been associated with greater internalising and externalising behaviour problems in the child, while later divorce may dampen academic performance. Children to unmarried parents tend to suffer greater emotional and social difficulties than others do.

Whereas father absence mainly result from parental divorce and separation, other factors such as family poverty, mixed or Black (compared to White) ethnicity have also been linked to the a greater likelihood of the father being absent when the child is 3 years old.

General Problems
Despite limited conclusiveness among researchers regarding the exact significance of fathering, fathers are traditionally deemed a provider of protection and support for the child’s development. Through a number of pathways, father absence may influence child behaviour especially in early and middle childhood. These include a decline in household income and ineffective parenting arisen from continued conflicts and psychological distress.

Total difficulties & specific difficulties
In regard to the effects of father absence, a recent British study assessed child problem behaviour on over 15,000 families using the clinical cut-offs of the Strengths and Difficulties Questionnaire (SDQ), controlling for household background such as resources, parental mental health and inter-parental relationship. The study found that father absence (at a given age), similar to poverty and parental psychological distress, predicted a high probability of the child scoring above the cut-off score for total difficulties two years after. Likewise, father absence predicted specific difficulties including borderline personality disorder, severe hyperactivity and abnormal emotional problems. Reciprocally, a child’s severe externalising and social problems (at a point of his/her preschool years) among the many indicators on the questionnaire was also associated with a greater probability of the father being absent two years after. The authors concluded that father absence seemed to be more of a cause than a consequence of child problem behaviour.

Evolutionary approach
Evolutionary life-history theory postulates that women may invest more in their offspring than the opposite gender does due to a slower rate of reproduction in females. Some theorists add that the assured maternal relatedness to one’s offspring may also make women invest more than men do. This is because some men may have variable paternity confidence that the child is his offspring. In light of this, some researchers argue that assured maternal relatedness, together with the lower variance in female reproductive success, may lead parents to bias investment towards female offspring under less favourable household conditions. In other words, father absence and the associated socioeconomic constraints it puts on the household may pose a greater risk to sons’ rather than daughters’ survival.

Psychodynamic approach
The psychodynamic approach posits that behaviour is motivated by basic needs, drives and sometimes shaped by unconscious childhood experiences. It is implicated that for a child to develop a “normal” gender identity, they will have to be raised in a conventional family where there is a father and a mother. Freud believed that being brought up by a single mother could confuse the child’s identity and/or lead them to become homosexual. Father absence may hinder the son’s acquisition of the traditional masculine role, as he is not able to model his own behaviour and attitude on his fathers’. In the same line, sons with absent fathers could have confused gender identities – if the son was separated from his father by age 4, he would be less assertive, less involved in sport, less masculine than other boys and more dependent on his peers. Nevertheless, findings of certain empirical studies on psychosexual gender identification have been deemed contradictory and inconclusive. A number of studies have highlighted such negative consequences of the two-parent heterosexual household on children. Contrarily, some others have pointed out that being reared in lesbian and single parent households where the father was absent did not affect the psychosexual development in children, despite higher aggressiveness and submissiveness, and lower assertiveness.

Biological approach
Genes and hormones may account for the tendency of father absence. Certain DNA patterns have been shown to affect an individual’s degree of fidelity and investment in their offspring. In particular, a study in prairie voles indicates that the gene avpr1a affects the activity of vasopressin receptor in brain regions, and thus predicts less cheating on their partners. Similar to oxytocin, the hormone vasopressin can facilitate trust, empathy and social bonding. Injection of vasopressin in polygamous montane voles significantly increased their likelihood of becoming monogamous. This may in turn decrease their likelihood of being an absent father.

A meta-analysis based on 56 twin and adoption studies totalling over 200,000 families has revealed that genetic makeup significantly affects the individual’s parenting behaviour. Genes in the father predict up to 40 per cent reliably his positive or negative emotions towards his children. In this sense, genes contribute to a father’s liking or repulsion for his children, the latter of which may result in father absence.

Gender difference
There is mixed empirical evidence on the relative impact of father absence on the development of male and female offspring. A recent study in rural Ethiopia, where father absence could mean a significant drop in household income, revealed a considerable difference between the wellbeing of male and female offspring. In particular, the author found that a male infant’s risk of dying (per month) was doubled if the biological father was absent – a 30% greater risk than females. For female infants, father absence (as opposed to presence) was associated with a lower risk of dying, as well as higher nutritional status. That is to say, father absence was only a statistical predictor of infant death for male infants. Such a gender difference has been observed despite a strong cultural preference for sons in the area. On the other hand, in developed countries such as United Kingdom where father absence may not inflict as much harm to the family's income, the impacts of father absence are not noticeably gendered.
