We believe that children need both parents.
And here’s the research that proves it!
Here is almost 100 pages of citations to published research, mostly from respected peer-reviewed journals, that outline the case for shared residence after divorce. This bibliography concentrated on Real Research about Real Children, not Freudian Fantasies.
This demolishes many of the points of the vested-interest advocacy groups who are resisting reform. These vested interest groups have no facts behind their positions. They use ideology combined with 1960’s Freudian Fantasies, not science.
Citations are arranged by subject matter and each has a brief summary of the relevant point.
This is designed to be a resource for reformers around the World.

Shared residence is best for children


Quantitative and Longitudinal Studies - 126 citations.

We have found 126 citations to published research showing that shared residence is better for children than any other kind of post-divorce residence.

Sole residence is justified on the basis of Attachment Theory. Attachment Theory suggests that stability and secure emotional attachments are crucial to a child’s emotional development. However (as we discuss in a later section) sole residence is an incorrect interpretation of Attachment Theory.

It is understandable why the Family Court initially gave Attachment Theory such primary significance in the 1970’s. Then there were few divorces and even fewer children in shared residence. With no facts, the court had to make decisions on theory alone.

However the last 30 years has seen vast numbers of children grow up in a wide variety of family circumstances and now, finally, there is an impressive number of large, well controlled and often longitudinal studies that compare whether children in shared residence actually do better, or worse in life, than children with a single parent. These studies record whether they reached their potential at school, whether they had emotional and behavioural problems, whether they had problems with drugs or teenage pregnancy, whether they have begun successful careers and so on…

These studies clearly demolish the idea that one primary parent and one primary home is preferable than having a meaningful relationship with both their natural parents.

So at last we can compare FACT with THEORY, and Attachment THEORY has been shown to be lacking. It is clear that having a meaningful relationship with dad is a greater benefit than any instability caused by having two houses.

Understandably is impossible to prove that 50-50 is better than 49-51. The research generally uses the concept of a ‘meaningful’ relationship with both parents. This is explored in a later section, but the Family Court’s standard every second weekend regime is clearly insufficient to maintain a meaningful relationship.

Longitudinal studies [18 citations]

A huge 33 year study tracked the lives of 17,000 individuals born in 1958. The study released in March 2002 found that close paternal involvement not only improves academic performance but also relationships and health. The benefits are greatest for youngsters who establish a strong bond from at least the age of seven. The highest scorers performed best at school, socially and in their marital relationships. After inspection of all the factors influencing a child’s later marital success, such as mental health, academic achievement and emotional behaviour, the influence of a father was most telling. Daughters benefiting from a strong paternal bond were less likely to have mental health problems and boys were less likely to get into trouble with the police.

In the Impact of Divorce Project of Ohio’s Kent State University––the first nationwide sample study of 699 elementary students from 38 American states––children from divorced homes performed more poorly in reading, spelling, and maths, and repeated a grade more frequently than did children in intact two parent families.
(a) the effects of divorce are not temporary stressors but rather long-term influences,
(b) boys have more difficulties, particularly as they approach adolescence,
(c) the decline in socio-economic status after divorce is not an explanation for children's decreased performance, and
(d) authoritative child-rearing routines such as bedtimes, mealtimes, and television viewing habits relate to better child outcomes.

One of the most striking findings was that 51% of children from sole mother custody families see their fathers once or twice a year or never. Even 11 or 12 years following the divorce, adolescents who have good relationships with their non-custodial fathers have fewer school behaviour problems, fewer attention or aggression problems, higher grades in Language and Social Studies, and are less likely to abuse drugs or alcohol.

These comparative studies compare children in sole parent household to children in other household types, and show that sole residence is the worst kind of residential situation for children.

The United States Congress has found:

(1) Nearly 24,000,000 children in the United States, or 34 percent of all such children, live apart from their biological father.
(2) Sixty percent of couples who divorce have at least 1 child.
(3) The number of children living with only a mother increased from just over 5,000,000 in 1960, to 17,000,000 in 1999, and between 1981 and 1991 the percentage of children living with only 1 parent increased from 19 percent to 25 percent.
(4) Forty percent of children who live in households without a father have not seen their father in at least 1 year and 50 percent of such children have never visited their father's home.
(5) The most important factor in a child's upbringing is whether the child is brought up in a loving, healthy, supportive environment.
(6) Children who live without contact with their biological father are, in comparison to children who have such contact:
(A) 5 times more likely to live in poverty;
(B) more likely to bring weapons and drugs into the classroom;
(C) twice as likely to commit crime;
(D) twice as likely to drop out of school;
(E) more likely to commit suicide;
(F) more than twice as likely to abuse alcohol or drugs; and
(G) more likely to become pregnant as teenagers.

(7) Violent criminals are overwhelmingly males who grew up without fathers.

(15) For the future of the United States and the future of our children, Congress, States, and local communities should assist parents to become more actively involved in their children's lives.

Children in joint residence were better adjusted than children in sole-residence. Children in joint residence were better adjusted than children in sole residence settings, but no different from those in intact families. Factors including, general adjustment, family relationships, self–esteem, emotional and behavioural adjustment, and divorce specific adjustment were considered. Moreover, joint residence parents reported less current conflict than did sole residence parents. Joint residence can be advantageous for children, by facilitating ongoing positive involvement with both parents

Equal groups in joint guardianship, sole maternal residence and joint residence were compared and the amount of father-child contact were found to be significant predicators of child adjustment, with higher father-child contact associated with better adjustment of the children. The results in this study, as in the vast majority of this research, suggest that joint residence is much more beneficial for successful post-divorce adjustment of children than sole residence.

Steinman evaluated 24 couples who chose joint residence arrangements for their children at divorce. The children felt that they were strongly attached to both parents and were not were not troubled by the loyalty conflicts. A comparatively low rate of the children experiencing confusion or anxiety to their shared residence arrangement. Consequently the argument that children in joint residence experience more confusion and frustration was not supported in that study.

Goldstein also found children were strongly attached to both parents, but a small number of these children felt a strong need to be fair to both parents and were meticulous about dividing their time equally between them. While these children did perceive their parents divorce as undesirable, and in some cases harboured fantasies of reconciliation, they did not experience the overwhelming sense of having been rejected that is common in the more usual maternal sole residence/father-absent post-divorce arrangement (Wallerstein, Kelly 1980; Mitchell 1985).

Boys in sole parent households frequently lack a positive male role model and miss the discipline exercised by most fathers. Half of Australian boys with separated parents see their fathers on the average of only six times a year or less. It is clear that many boys are being reared without benefit of a same-sex parental figure.

If economic hardship were the main predictor of school performance, there would presumably be no difference between children in step-parent households and children in intact families where both family types received similar incomes.

Increased contacts in meaningful care giving situations, lead to improved behaviour, improved peer relationships, more positive self-esteem, and even improved academic scores in numerous subjects.

Children obtain emotional stability from important emotional relationships with two parents and two sets of grandparents, and these are much more important than where a child sleeps.

Children in sole residence situations did not maintain strong healthy emotional relationships with both parents, children in joint residence situations did. The children in joint residence arrangements indicated that they were generally satisfied with their level of involvement with both parents, in marked contrast, children in sole residence indicated that they were not satisfied.
* The claim that children of divorce need one primary parent and one primary home is refuted.
* There was no evidence that joint residence families sustained more post divorce conflict than sole residence households;
* There was no evidence that children experience disruption from living in two houses. In fact, most children felt their new lifestyles held certain advantages over the nuclear family household;
* Children in sole residence desired more contact with their non-resident parents;
* Many non-resident parents but no joint residence parents lost contact with their children;
* No joint residence fathers had ceased to support their children financially, as many non-resident fathers had;
* Joint residence children had maintained meaningful relationships with both parents, in contrast with single residence children for whom the visit was a vacation;
* Single residence parents reported feeling burnt out and overwhelmed in a way that joint residence did not.
* All of the joint residence children valued the arrangement and said they would have chosen it. By contrast, half of the sole residence children were dissatisfied with their arrangements and wanted more contact with the non-resident parent.
* Children’s response to parental authority were not shown to be adversely affected by the fact that their parents no longer cared for each other. Joint residence should be a rebuttable presumption at law. She concluded that joint residence at it's best is superior to sole residence at its best.

There is a general consensus that children who are able to maintain a loving, involved relationship with both parents after divorce adjust much better than children who find their relationship with either parent curtailed.

Roman M, Haddad W. The Disposable Parent: The Case For Joint Custody. Holt, Rinehart, Winston, New York (1978)

Children seem to benefit from increased time with the non-custodial parent when certain conditions are met: low levels of inter-parental conflict and a warm, consistent relationship with the non-custodial parent. They benefit from authoritative parenting with the non-resident parent (i.e., advice and help with projects, supervision of homework; discipline)... In other words, how often fathers see their children is less important than what they actually do with them. (Alternate weekend access leads to destructive ‘Disney Dad’ relationships, as fathers are forced to try to maximise the joy in their infrequent visits – ed.)

Australian data indicates the proportion of children with mental health problems – including behavioural, affective (mood), and attention deficit disorders – is lowest in intact families. The highest proportion of children with problems occurs in single parent households, but boys are most likely to suffer from mental health problems in step/blended households.

An important Australian study interviewed 402 Victorian children and asked them about relationships with parents and their general feelings about family life. It sought to connect their responses to how the children were doing in their lives. For the broad range of children support from both mothers and fathers was associated with positive development. When fathers had little association with their children, these children had relatively low self-esteem, strongly desired more contact with their fathers, and were doing poorly compared to other children whose fathers were more involved in their lives.

Numerous authors have expressed concern about the injury to children when a parent with psychological problems is given total responsibility for the children. Decisions in favour of sole residence will result in awarding residence to a small number of parents who have serious psychological problems. Given the total authority which parents in sole residence situations have, the potential for child abuse, in that context, is almost unchecked.

These data could result from the increased stress associated with single parent responsibilities, since the Ditson, Shay (1984) data also indicated that in married families the abuse was evenly split between the mother and the father.

Child abuse is intimately related to later delinquency and violent crime, and here too divorce is implicated.

When parenting responsibilities are totally loaded totally on one parent, sole residence may lead to increased parental stress, and research has associated increased maternal stress with increased violence against children.

Delinquency and crime [29 citations]

It has also been found that boys from divorced families often exhibit delinquent-like behaviour and have difficulty in controlling their impulses (Biller 1981; Buckingham 2000). Investigators believe that boys need a firm, positive identification with their fathers in order to be able to develop internalised controls over their behaviour. The fact that post divorce boys have much less contact with their fathers would explain their higher incidence of delinquent-like and generally aggressive behaviour.

Assault rates more than doubled in the decade from 1980 to 1990 and there is a statistical association between rising crime and rising rates of divorce. (There is no such association between crime and unemployment or the number of young men in society).
Intact families are generally the most effective way to socialise the young. Disturbed behaviour among young people was noted during World War II, when many fathers were away from their families. Sullivan suggests that our present way of dealing with this problem, through intervention at the individual level by social workers and the police, has little effect, and calls for a public health approach, preventing the problems before they occur by encouraging intact families.

"The high incidence of violent behaviour from boys was strongly correlated to being fatherless but it was not, in my experience, prevalent among any one community. It was not related to one race or community, but it was related to having no father."

Other American data indicates that 43 percent of prison inmates grew up in a single–parent household and an additional 14 percent lived in households without either biological parent. Another 14 percent had spent at last part of their childhood in a foster home, agency or other juvenile institution. (adding this up, 70% of inmates didn’t have both natural parents, ed.)

The one factor that most closely correlates with crime is the absence of the father in the family. Controlling for family configuration erases the relationship between race and crime and between low income and crime. This conclusion shows up time and again in the literature

One U.S. study tracked one thousand families with children aged six to eighteen for six years and found that those children living in intact married families exhibited the least delinquency, while children with stepfathers had the greatest risk of the most disruptive behaviour. In this study single-parent children fell in between.

Higher divorce rates in a society lead to higher suicide rates among children. Prior to the divorce revolution of the 1970s unemployment was the biggest correlate with suicide, but that has changed (McCall et al). The largest demographic indicator of suicide is the family structure within which the person resides, and that the divorced family structure is most dangerous. This link between the rise in adolescent suicide in the past three decades with parental divorce has been found again and again in the literature, and in cross-cultural studies of Japan and the United States. For children the suicide is often triggered by thoughts that their parents have rejected them or have lost interest in them (Wodarski et al).

Some experts to recommend paternal residence as a preference for boys and maternal residence for girls. However, such a legislative mandate would be inappropriate at present for two reasons. First, no child should ever be denied the right to know and love two care-giving parents (except, obviously, in abuse situations). Second, no parent should be denied his or her parental rights (i.e., human rights) without conclusive evidence that the exercise of those rights is destructive of the child). Thirdly, This can deny children from having a relationship with their siblings.
Finally, this would fail to achieve the only justification of sole-residence – which is to remove one parent from the children’s lives.
