Question ID: 214324
I am looking for any research that quantifies the benefits or
disadvantages of shared custody with sole custody for children under
10-years old from divorced families.  I want statistics or research to
either support or refute the claims that shared custody is better for
the children than sole custody.

Hello, benfranklin-ga


 There is a mountain of research on child custody issues. However, by
restricting my search to the parameters of "children under 10 years
old," I came up with fewer references than I had hoped. Lack of access
to full journal articles only allowed me to mention references to
those studies that highlighted the ages of children in the abstract.

 If you would like me to expand my references to those articles which
discuss the pros and cons of joint versus sole custody, without
mention of age in the abstract, please let me know. I do not have the
resources to search the articles for age references unless I do
offline library research, which would require considerable time and
effort not covered by the price of this question.

 However, if you have a research library at your disposal, I will be
more than happy to provide a broader list of research titles.

 A short summary of research study results can be found on the
following page:

"Research on Shared Parenting and Joint Custody."
http://www.horut-shava.org.il/legistlation/custody/research_on_shared.htm


 To reiterate, I have excerpted only the relevant abstracts that fit
the age parameters of children under 10 years old. If there is no age
level mentioned, I have left out the reference. However, you may be
interested in the other studies even though the abstracts do not
specifically mention age. Access to the actual journal may go into
more depth about the ages of children in the research studies.


Rockwell-Evans, Kim Evonne, "Parental and Children’s Experiences and
Adjustment in Maternal Versus Joint Custody Families." Doctoral
dissertation, 1991. North Texas State U.
===============================================================================

This study compared 21 joint custody and 21 maternal custody families,
with children between the ages of 4-15.

Results showed that misbehavior and "acting out" were more common
among sole custody children: "A multiple regression analysis of these
data found children in joint custody families had fewer behavioral
adjustment problems with externalizing behavior than children in
mother custody families." "Regardless of custody arrangement, parents
with low self esteem were more likely to have children with behavioral
adjustment problems when predicting the child’s overall behavioral
adjustment and internalized behavior."


Glover, R. and C. Steele, "Comparing the Effects on the Child of
Post-divorce Parenting Arrangements," Journal of Divorce, Vol. 12, No.
2-3 (1989).
============================================================================

This study evaluated children aged 6 to 15 in the areas of locus of
control, self-concept, and family relationships.  The children were
divided into three groups:  shared custody, maternal custody, and
intact families.  Intact family children had averaged higher than
divorced family children on self-concept and father relationships, and
shared custody children averaged higher the sole custody children in
these areas.  Intact family children had fewer least-positive
responses in all areas than divorced family children, and shared
custody children had fewer least-positive responses than sole custody
children in all areas except mother relationship.  This study
indicates that, on average, a two parent intact family is the best
arrangement for children, and a shared parenting arrangement is better
than a sole custody arrangement, i.e., a two-parent family is better
even if parents are divorced.



Lerman, Isabel A. "Adjustment of latency age children in joint and
single custody arrangements." California School of Professional
Psychology, San Diego, 1989
=============================================================================

This study evaluated 90 children, aged 7 to 12, divided equally among
maternal, joint legal, and joint physical custody groups.

Results showed negative effects for sole custody: "Single custody
subjects evidenced greater self-hate and perceived more rejection from
their fathers than joint physical custody subjects." Conflict between
parents was found to be a significant factor, which may explain the
better adjustment for joint physical custody children: "Degree of
interparental conflict was a significant predictor of child self-hate.
Higher conflict was associated with greater self-hate; lower conflict
was associated with lower self-hate." "Higher father-child contact was
associated with better adjustment, lower self-hate, and lower
perceived rejection from father; lower father-child contact was
associated with poorer adjustment, higher self-hate, and higher
perceived rejection from father.

 
Wilkinson, Ronald Richard, "A Comparison of Children’s Post-divorce
Adjustment in Sole and Joint Physical Custody Arrangements Matched for
Types of Parental Conflict" Doctoral dissertation, 1992; Texas Woman’s
University
===============================================================================

This study included "forty boys and girls, ages 8 to 12, in attendance
at selected private secular and parochial schools in a large
Southwestern metropolitan area participated, along with their middle
to upper-class parents." The study compared adjustment of children in
joint and sole physical custody, controlling for level of conflict
between parents, to determine if parental conflict would be more
detrimental to children in joint or sole custody.  The author
summarized findings as follows: "Overall, no significant difference
between joint and sole physical custody groups was found."

 Unfortunately, once again, there are few that mention ages of the
children without having full access to the journals to read the actual
studies. However, you may want to pick out a few references if you
have the journals available.

I would welcome any research on the pros and cons of joint vs. sole
custody even if age is not mentioned.  Additionally, gender specific
issues would also be important, if available.  Specifically, is there
a difference between girls being raised by their mothers in sole
custody vs. girls being raised by both mothers and fathers in joint
custody.

Thanks!

Hello again, benfranklin-ga!


 I certainly hope I haven't overwhelmed you here! There is so much
research available. I wish the citations had actual online links to
the articles, but most journal archives require a special
subscription. However, I still hope this extra research is helpful.


 I could have found more, but I think you could be overcome by a
serious case of brain fog, so I have decided to stop here! (There are,
as you requested, some articles that provide specific references to
the effect of joint or sole custody on girls)


 Let me know if I can be of help again in the future!

"Adolescents After Divorce, Buchanan, C., Maccoby, and Dornbusch,   
Harvard University Press,1996.
http://www.horut-shava.org.il/legistlation/custody/research_on_shared.htm

A study of 517 families with children ranging in age from 10.5 years
to 18 years, across a four and a half year period. Measures were:
assessed depression, deviance, school effort, and school grades.  
Children in shared parenting arrangements were found to have better

Report to the U.S. Commission on Child and Family Welfare, June 14,
1995."
http://www.horut-shava.org.il/legistlation/custody/research_on_shared.htm

This report "summarizes and evaluates the major research concerning
joint custody and its impact on children’s welfare." The report
concludes that "The research reviewed supports the conclusion that
joint custody is associated with certain favorable outcomes for
children including father involvement, best interest of the child for
adjustment outcomes, child support, reduced relitigation costs, and
sometimes reduced parental conflict." The APA also noted that "The
need for improved policy to reduce the present adversarial approach
that has resulted in primarily sole maternal custody, limited father
involvement and maladjustment of both children and parents is
critical. Increased mediation, joint custody, and parent education are
supported for this policy."

Note:  This report was approved and submitted by Division 16 of the
APA, and is a part of the public record.  However, it is not listed
among official APA publications;  it was quashed because it did not
fit the political ideology of those at the top of the APA.

custody, joint custody and intact families." Doctoral dissertation, U.
of California, Davis 1989
http://www.horut-shava.org.il/legistlation/custody/research_on_shared.htm

This study evaluated children’s perceptions of their fathers at least
four years post-divorce, comparing joint custody, sole custody and
intact families. The subjects were 43 latency-age children: 11 from
maternal custody families, 14 from joint custody families and 18
controls from intact homes.

Results: "There was a significant difference in the perceptions of
children in sole and joint custody. Joint custody children reported
spending more time with their fathers in childcentered activities,
activities which were considered pleasurable and important to
children. "And: "No differences were found as a function of custody
arrangements in children’s perceptions of emotional closeness to the
father, acceptance by the father, or fathers’s potency or activity."

 Research reveals that the parent's mental health must be relatively
stable for the shared custody to provide any benefit over sole
custody.

Chances," by  J. Wallerstein and S. Blakeslee; and other publications.
http://www.horut-shava.org.il/legistlation/custody/research_on_shared.htm


 Judith Wallerstein and colleagues have produced many publications on
a 20+ year study of 184 families that had been referred to her clinic
for therapy. The parents were predominantly mentally ill, with
approximately half the men and half the women "moderately disturbed or
frequently incapacitated by disabling neuroses and addictions,"
including some who were "sometimes suicidal." An additional 20% of the
women and 15% of the men were categorized as "severely disturbed."
Approximately one third of the sample were considered to have
"adequate psychological functioning" before divorce. Although there
was a significant level of attrition, with families dropping out of
the study when problems were resolved, some conclusions emerged from
the remaining families.
 
"Children in joint custody situations did no better than those in sole
custody, indicating that:

 *parents must be reasonably psychologically healthy for shared
parenting to benefit children.*

"This study evaluated 273 families, controlling for 28 variables that
influence a predisposition to agree on joint legal custody. 
Controlling for these factors, children in joint legal custody
families had more time with their fathers and fewer adjustment an
behavior problems."

Study consisted of 378 families; some with unmatched partners, in
various custody arrangements.

". . .Sharlene Wolchik, Iwrin Sandler and I found in 1985 that
children in joint custody had higher feelings of self-worth than
children in sole maternal custody."

"Our results showed considerable benefits for joint custody, even when
equating predisposing factors. After this adjustment, children in
joint custody were found to be significantly better adjusted, and to
exhibit less antisocial and implulsive behavior than sole custody
families. Fathers also visited more, and were more involved in child
care, as well as more satisfied with the divorce settlement."

================================================================================================================================================================


CUSTODY IMPACT ON BOYS AND GIRLS:



 The following excerpts are from the article, "The Effects of Divorce
on Children, " by Jeff Wood. UCLA.
http://www.bol.ucla.edu/~jeffwood/res.html



"Few studies have directly compared mother and father custody.
However, of those that have, there is some support for the assertion
that pre-teen boys do better in father rather than mother custody
(Hetherington, et al, 1998), whereas the reverse may be true for girls
(see the early work of Santrock, Warshak, & Elliott, 1982; Warshak &
Santrock, 1983). A recent study (Clarke-Stewart & Hayward, 1996)
provides further support."

"In an impressive study including 187 children from divorced families,
Alison Clarke-Stewart and Craig Hayward (1996) examined how
elementary-aged children fared in mother vs. father custody. Similar
to (though subtley different from) the findings of Santrock and
colleagues in the early 80's, father custody was found to be linked
with significantly better adjustment for boys.

***
 Interestingly, father custody was also linked with somewhat better
adjustment among girls, though not as in many areas as for boys.
***

 Due to the large sample-size in this study, it is worth specifying
exactly which domains of adjustment showed improvement."
 

"For boys, father custody was associated with lower levels of
depression, higher self-esteem, fewer fewer parental ratings of the
child as "difficult", and substantially lower anxiety. These measures
were based on standard parent questionnaires, child questionnaires,
and child interviews."

***
For girls, father custody was associated with lower levels of
depression and anxiety. An interesting additional finding was that
both girls and boys in father custody were more likely to draw a
picture of both parents, rather than just the custodial parent, when
asked to draw a picture of their family.
***

"Children in father custody were also more likely to have liberal
access to their non-custodial parent than children in mother custody.
This was undoubtedly an important factor in why these custodial
fathers had children who were so well adjusted. There appeared to be
less negativity toward the non-custodial parent on the part of
custodial fathers. Allowing a great deal of contact with the mothers
undoubtedly gave the children more of the benefits of having two
parents."


"The other important finding in Clarke-Stewart's study was that
children in mother custody who had liberal access to father (a fairly
small group) fared just as well as children in father custody. This
finding suggests that a strong, consistent relationship with both
parents is perhaps the most important predictor of child adjustment in
comparisons of custody arrangements. Mothers and fathers who isolated
their children from the non-custodial parent generally had less happy,
less well-adjusted children. These results are consistent with some
studies comparing joint custody and sole custody (discussed below)
which find joint custody to be the "option of choice". Of course,
there are situations in which the parents simply cannot share custody,
due to personal or geographic considerations. In these cases, it may
be very important to consider parent and child gender when determining
who should have custody. Clarke-Stewart and Hayward's study is an
exceptional beginning to what I hope will be a fresh generation of
custody studies looking with increasing depth at gender issues."

As a side-note, the results on mothers versus fathers for adolescents
(as opposed to pre-teen children, as discussed above) have not shown
much of a consistent advantage for mother or father custody (eg.
Maccoby et al., 1992). It may be that whichever parent is better able
to keep track of what their teenagers are doing is going to be the
more effective parent at this age. Perhaps gender considerations
become less important in comparison to firm, effective parenting for
adolescents.

Joint custody versus sole custody has also been a topic of interest
among researchers. Bender (1994) recently reviewed the literature and
found that the majority of studies indicate that joint physical
custody is better than sole custody from the standpoint of children's
adjustment. For one of the more influential and well-designed studies
on this topic, see Wolchik, Sandler, and Braver (1985), who found that
joint custody was superior in numerous ways. However, some criticisms
of the research on joint custody must be considered, as well (Depner,
1994). Depner suggests that joint custody may be chosen by families
that are less disturbed than families that opt for sole custody. This
is a possibility which should be investigated in a prospective study
of pre-divorce families.

"This research discovers that children--* especially daughters

nevertheless does everyday things with the child, from 'shopping,
reading, visiting, doing homework, watching TV together,' to 'spending
holidays together.' The authors conclude that, for a school-age
daughter, this 'doing everyday-type things together' with the parent
she is not living with is the only predictor of psychological
well-being."

be more active than in sole custody families or intact families. In
low conflict situations children did better (demonstrated less
withdrawal) than in either sole custody or intact families.

S.A. Nunan. Joint custody versus single custody effects on child
development. Doctoral thesis 1980. California School of Professional
Psychology, Berkeley, UMI No. 81-10142

"Nunan compared 20 joint custody children (ages 7-11) with 20
age-matched children in sole maternal custody. All families were at
least two years after separation or divorce. Joint custody children
were found to have higher ego strengths, superego strengths and
self-esteem than the single custody children. The joint custody
children were also found to be less excitable and less impatient than
their sole custody counterparts. For children under four at the time
of separation the differences were very small."
