emellis@mindspring.com
The following is a summary of highlights of the text, Divorce
Wars, Interventions with Families in Conflict, (APA Books,
2000).
The text is a review of research in a number of key areas
and is intended as a reference work and manual for psychological
experts in the courtroom and the attorney who wishes to be
knowledgeable regarding the scientific literature in this
field. The book also contains case studies, guidelines for
clinicians, charts and data tables, as well as a complete
bibliography. (The last two chapters, on ethical dillemmas
and future trends in the area of divorce and family law, have
not been reviewed here).
This summary is organized in a list of pertinent questions
and brief responses to these questions. For the full text

(1) In terms of the effects of divorce on children, as a group,
we can conclude that divorce roughly doubles the rates of
emotional and behavioral adjustment problems in children.
Though the effect sizes are small, they are very consistent
(see: Gregory, 1965; Hetherington, 1989; Hetherington, Cox,
& Cox, 1985; Hetherington, Stanley-Hagan, & Anderson,
1989; Wallerstein, 1985; Wallerstein, 1991; Wallerstein &
Blakeslee, 1989; Wallerstein & Kelly, 1980b; Zill, Morrison,
& Coiro, 1993; Zimiles & Lee, 1991).
(2) The effects of divorce on boys appear to be more immediate
and dramatic, especially in mother-headed households. These
are increases in aggressive, disruptive, acting out behaviors.
Boys in single-mother households are considered to be “developmentally
vulnerable” and at risk for high levels of acting out
behavior (Gregory, 1965; Kalter, 1977, 1987; Hetherington,
1989; Hetherington, Cox, & Cox, 1985; Warshak, 1992; Zaslow,
1988, 1989; Zimiles & Lee, 1991).
(3) The effects of divorce on girls (provided mother doesn’t
re-marry), are minimal, until adolescence. Girls of divorce
show no increased risk of behavior problems, as compared with
girls from intact families, until adolescence. Then, they
show increased rates of running away, skipping school, sexual
promiscuity, and acting out. These girls are more likely to
drop out of school and become pregnant outside of marriage.
This has been dubbed “the sleeper effect”. (Allison
& Furstenberg, 1989; Hetherington, 1989; Hetherington
& Deur, 1971; Hetherington, 1991; Kalter, 1977; Kalter,
et al., 1984; Hetherington, 1972, 1973).
(4) The adult children of divorce experience
lower levels of reported happiness, higher levels of sychological
problems, lower levels of marital happiness, and a higher
rate of divorce in their own marriages . This is kown as the
intergenerational transmission of divorce (Amato, 1996; Kulka
& Weingarten, 1979; Glenn & Kramer, 1985; Glenn &
Shelton, 1983).
(5) Women who come from divorced homes are more
likely to have their own marriages end in divorce than men
from divorced homes. When both will end in divorce is triple
that of a couple who both grow up in intact homes (Amato,
1996).
(6) What seens to be transmitted to the children
of divorce is a tendency toward lower rates of education,
early marriage, living together before marriage, and a group
of behaviors which can be described as: lower commitment to
marriage, infidelity, problems with anger management, feelings
of insecurity, neediness, demandingness, denial and blame,
contempt, and poor conflict resolution skills (Amato, 1996;
Hetherington, Bridges, Insabella, 1998).
At this time, we are not sure if what is being
transmitted is genetic-biochemical, or behavior patterns that
are learned, or some interaction of both. See O’Connor,
et al. (2000), for a complete discussion of this topic.
(7) The effects of divorce on children are not explained through
parental loss or economic hardship. Children who lose a parent
through a lengthy illness or even death fare better than the
children of divorce, and economic status post-divorce is not
a good predictor of chldren’s adjustment. Mother’s
remarriage, which is associated with a higher standard of
living, is not associated with improved outcomes for children
(Amato & Keith, 1991; Rutter, 1971; Rutter, et al., 1976;
Shaw & Emery, 1987).
(8) The effects of divorce on children occur
largely through
the effects of inter-parental conflict on children, both before
and after the divorce (Amato & Keith, 1991; Amato &
Rezac, 1994; Amato, Loomis, & Booth, 1995; Buchanan, Maccoby,
& Dornbusch, 1991; Camara & Resnick, 1988, 1989; Emery,
1982; Kline, Johnston, & Tschann, 1991; Long, Slater,
Forehand, & Fauber, 1988; Rutter, 1971).
This is one of the most consistent findings
and the above reference list is abbreviated. Amato and Keith
(1991) reviewed 15 studies. Emery (1982) reviewed over 20
studies, most of which are not listed above. The “high
conflict” factor predicts a poor parent-child relationship
(#11), predicts the outcome of joint custody (#28), and predicts
whether time with the non-custodial parent is benefecial or
distressing (#38).
(9) Children and teens from divorced homes where
there is no conflict, fare better than children and teens
from intact homes where there is chronic conflict. On the
surface, one would expect children to benefit from divorce
based on this finding. However, in reality, the children of
divorce seem to endure years of conflict prior to their parents’
divorce; the conflict often continues unabated after the divorce,
or even intensifies; and many parents go on to marry again
and have highly conflicted remarriages. (Rutter, 1971; Long,
Slater, Forehand, & Fauber, 1988; Camara & Resnick,
1988, 1989; Kline, Johnston, & Tschann, 1991; McCord &
McCord, 1959).
(10) The type of conflict matters. Children
do not appear to be affected much by conflict which is characterized
by emotional distance and tension. They are more negatively
affected by conflict that is open, attacking (both verbally
and physically), and where the children are exposed to the
conflict and caught up in it (Camara & Resnick, 1988,
1989; Emery, 1982; Kline, et al., 1991; Buchanan, Maccoby,
& Dornbusch, 1991).
(11) The mechanism through which inter-parental
conflict exerts its negative influence on the children of
divorce is through a deterioration of the parent-child relationship.
Second and third divorces deteriorate the parent-child relationship
even further (Amato & Booth, 1996; Emery, 1982; Hess &
Camara, 1979; eterson & Zill, 1986; Kline, et al., 1991;
Tschann, Johnston, Kline, & Wallerstein, 1989). When children
live in intact families where conflict is low, 62% report
having a good relationship with both parents. Where conflict
is high and persistent, only 20% do so Where children live
with a mother who has divorced a second time, only 8% report
having a good relationship with both parents. Fully 46% report
a poor relationship with both parents (Peterson & Zill,
1986).
(12) The emotional stability, warmth, and consistency
of the primary custodial parent is a strong factor in predicting
children’s adjustment to divorce. Children who reside
with a parent who is emotionally unstable, depressed, and
angry experience poorer outcomes (Emery, 1982; Hess &
Camara, 1979; McCombs & Forehand, 1989; Thomas & Forehand,
1993; Tschann, Johnston, Kline, & Wallerstein, 1989; Wallerstein
& Blakeslee, 1989).
(13) The effects of chronic conflict on children
also exert their effect through inducing in the child a feeling
of chronic stress, insecurity, and agitation (Davies &
Cummings, 1994); shame, self-blame, and guilt (Grych &
Fincham, 1993); a chronic sense of helplessness (Davies &
Cummings, 1994); fears for their own physical safety (Davies
& Cummings, 1994); a sense of rejection, neglect, unresponsiveness,
and lack of interest in the child’s well being (Davies
& Cummings, 1994; Fauber, et al., 1990; Fantuzzo, et al.,
1991; Johnston, 1992)
(14) Women are by far more unhappy with the current state
of marriage. They initiate 75% of divorces (Wallerstein and
Kelly, 1980b), 76% (Koel et al., 1988), or 80% (Furstenberg
& Cherlin, 1991), depending on the study.
(15) Second marriages have a higher rate of
failure. Furstenberg (1987) found the rate of divorce of second
marriages to be 56%. Glick (1984) found the divorce rate of
second marriages to be 57%. Baydar (1988) found that 42% of
second marriages ended within 5 years.
(16) In general, no. If one reviews the large volume of studies
on this question, one finds that in about half the studies,
children do a little better. In about half the studies, children
do a little worse. Although the children might benefit a little
from an increased standard of living, these gains are offset
by increases in inter-parental conflict, and conflictual relationships
with stepparents and stepsiblings. To look at somewhat predictable
findings, you need to look at factors such as the child’s
age, and gender, and who it is that is remarrying.
(17) Broadly speaking, remarriage appears to
benefit young boys who live in single mother households and
whose fathers are absent or uninvolved. These boys are eager
for a male role model. Acting out behavior is reduced (Hetherington,
Cox, & Cox, 1985; Hetherington, 1989; Kalter, 1977; Zaslow,
1988, 1989; Zill, Morrison, & Coiro, 1991; Zimiles &
Lee, 1991).
(18) Broadly speaking, remarriage fares rather
badly when one is looking at adolescent girls in single mother
custody homes. They universally reject stepfathers, despite
the best of efforts on the part of mother and stepdad (Hetherington,
Cox, & Cox, 1985; Hetherington, 1989; Kalter, 1977; Zaslow,
1988, 1989; Zill, Morrison, & Coiro, 1991; Zimiles &
Lee, 1991).
(19) Of those who attend and complete mediation, rates
of reaching out of court agreements are fairly high. Emery’s
(1987) review found rates of 55% in a California study and
64% in a Connecticut study. Emery & Wyer (1987) report
rates of 75%; Saposnek (1984) also reported rates of 75%.
Pearson & Thoennes (1984) reported that 50% settled through
mediation, and another 30% settled just before going to court.
(20) Regarding relitigation rates, Pearson and Thoennes (1982),
Emery & Wyer (1987) and Scott & Emery (1987) all report
lower rates of relitigation in the year following divorce
in the group who mediated and settled out of court.
(21) Mediation appears to have no effect on
children’s post-divorce adjustment, nor on the parents’
adjustment, nor on the ability of the parents to work together
over the long-term (Pearson, Thoennes, & Hodges, 1984;
Emery, 1988; Dillon & Emery, 1996; Kelly, 1996; Saposnek,
1998).
(22) Boys as a group are happier and show lower
rates of delinquency and school drop-out in father-custody
homes. (Camara & Resnick, 1988; Clarke-Stewart & Hayward,
1996; Gregory, 1965; Peterson & Zill, 1986; Santrock &
Warshak, 1979; Warshak, 1996; Warshak & Santrock, 1983;
Zimiles & Lee, 1991).
(23) Girls, as a group, are happier and show
lower rates of delinquency and school drop-out in mother-custody
homes (Camara & Resnick, 1988; Clarke-Stewart & Hayward,
1996; Gregory, 1965; Peterson & Zill, 1986; Santrock &
Warshak, 1979; Warshak, 1996; Warshak & Santrock, 1983;
Zimiles & Lee, !991).
These results are consistent and robust. There are no studies
which find the reverse - that children function better with
the opposite-sex parent. However, some have suggested that
this may be an artifact of demographic differences between
mothers and fathers who are primary custodial parents, e.g.,
fathers who pursue and are awarded custody are generally more
educated, more affluent, have more professional occupations,
and have been more involved with their children.
(24) Split custody is rarely recommended by courts and by
custody evaluators (Maccoby & Mnookin, 1992; Simons, Grossman,
& Wiener, 1990; Greif, 1990; Hauser, 1995). However, there
is no established research that has determined that it is
associated with poor adjustment to divorce.
Many writers in the field have noted anecdotally that many
families drift toward split custody over time following the
divorce as the children mature and their needs change, or
as the family composition of the two households change. Therefore,
it is a custodial arrangement that is frequently naturally
selected by families, and those families report good outcomes
(Greif, 1990, Hawthorne, 2000).
(25) Parents who share child rearing in joint custody arrange-ments
(the type of “joint” custody is frequently unspecified)
are generally happy with it and satisfied with it. They report
that children see their father more often. Mothers report
feeling less overwhelmed (Pearson & Thoennes, 1990; Rothberg,
1983; Luepnitz, 1986).
(26) Reports on whether parents litigate less often with joint
custody or have less conflict are less clear. Some studies
report lower rates of re-litigation (Luepnitz, 1986; Ilfield,
Ilfield, & Alexander, 1982); some report higher rates
of re-litigation (Albiston, Maccoby, & Mnookin 1990; some
studies found no differences (Koel, et al., 1988; Pearson
& Thoennes, 1990).
(27) Children’s emotional adjustment is not associated
with custodial arrangement (Steinman, 1981; Luepnitz, 1986;
Kline, et al., 1989; Pearson & Theonnes, 1990; Johnston,
1995).
This is one of the most robust findings in the literature.
Johnston (1995) reviewed 14 studies and concluded that there
were few, if any, differences in the adjustment of children
by virtue of the type of custodial arrangement in which they
lived.
(28) Studies show that the vast majority of divorcing
families do manage, through attorney bargaining, and through
mediation, to settle out of court. Estimates vary from “less
than ten per cent” (Kornhauser, 1979); 10% (Maccoby
& Mnookin (1992), to 10% to 17% (Rohman, Sales, &
Lou, 1987).
(29) Parents’ race, age, education, and income are not
predictive of who goes to court. Parents typically go to court
over one or two very young children (Maccoby & Mnookin,
1992; Dixon, 1991).
(30) Since most mothers ask for and receive primary custody,
the decision to litigate over custody is usually made by the
father, when the father expresses disagreement with this arrangement
(Dixon, 1991; Maccoby & Mnookin, 1991).
(31) Though psychological tests are widely used in custody
evaluations, their use in this context is, for the most part,
highly spurious and scientifically unsupportable (Brodzinsky,
1993; Grisso, 1986; Hawthorne, 2000; Heinze & Grisso,
1996; Melton, Petrila, Poythress, & Slobogin, 1997; Weithorn
& Grisso, 1987).
(32) There are only a few tests which have demonstrated validity
and usefulness in custody evaluations. These are: the Child
Abuse Potential Inventory (Milner, 1990); Parent Child Relationship
Inventory (Gerard, 1994); the Parenting Stress Index (Abidin,
1990); and the Children’s Reports of Parental Behavior
(Schaefer, 1965).
(33) In making recommendations for custody, both judges
and mental health professionals place high value on the parent’s
stability and the presence of alcoholism. However, mental
health professionals tend to place higher value on the children’s
bond with the parent and the children’s wishes; judges
tend to place greater emphasis on issues such as whether the
parent is cohabiting, whether the parent is gay, whether the
parent has had an affair, etc. In other words, judges may
come at these issues with a more conservative bent and a focus
on what society may consider to be “moral character”
issues (Lowery, 1981; Felner, et al., 1985; Sorenson &
Goldman, 1989; Reidy, Silver, & Carlson, 1989; Keilin
& Bloom, 1986; Ackerman & Ackerman, 1997).
(34) Studies of the impact on children who have been
the subject of custody disputes are surprising. They consistently
indicate that participating in the evaluation does not appear
to be associated with poor outcomes but rather with higher
self esteem and a greater sense of control (Ash & Guyer,
1986; Fulton, 1979; Wolman & Taylor, 1991).
(35) Not much at all. There are no controlled studies which
indicate that any visitation pattern is best for a child of
a certain age. All we have to go on is clinical experience,
and extrapolations and educated guesses which have been derived
from the child development literature (studies of babies in
daycare; studies of infant attachment; studies of separation
anxiety, etc.)
(36) Quite common. Non-custodial fathers report higher
figures than custodial mothers, naturally. Fulton (1979) reported
that 53% of fathers had had their visitations blocked; Pearson
& Thoennes (1988) said 20% of fathers reported problems
with blocked visitations; Braver et al. (1991) said 33% of
noncustodial fathers reported loss of visitations; Arditti
(1992) reported a figure of 50%. Custodial mothers have admitted
denying visitations in these ratios: 40% (Fulton, 1979); 20%
(Wallerstein & Kelly, 1980); 40% Kressel (1985); 23% (Braver
et al.).
(37) Children do not necessarily benefit from more time with
the non-custodial parent. If there are high levels of inter-parental
conflict, children may exhibit more adjustment problems with
increased the non-custodial parent. (Amato & Rezac, 1994;
Ash & Guyer, 1986; Baydar, 1988; Bray & Berger, 1990;
Furstenberg, Morgan, & Allison, 1987; Healey, Malley,
& Stewart, 1990; Hess & Camara, 1979; Hetherington
& Parke, 1979; Hodges, Wechsler, & Ballantine, 1979;
Johnston, Kline, & Tschann, 1989; Kalter, Kloner, Schreier,
& Okla, 1989; King, 1994; Kline, Johnston, & Tschann,
Thomas & Forehand, 1993; Wallerstein & Corbin, 1989;
Zill, 1988). This is one of the most robust findings in the
research literature. I have compiled 17 studies at this time
in which no association is found between frequency and length
of visitations with non-custodial dad and children’s
emotional/behavioral adjustment. It is troubling, but remarkably
consistent.
(38) 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. (Amato & Gilbreath, 1999; Clarke-Stewart
& Hayward, 1996; Hetherington, Cox, & Cox, 1982).
(41) Boys with difficult temperaments fare very
poorly with divorce, and these boys can be identified as young
as age 3 (Amato & Booth, 1996; Block, Block, & Gjerde,
1986; Cherlin, et al., 1991; Jouriles, et al., 1991). This
seems to be due to a complex interaction between the genetic
transmission of certain temperament factors, poor parenting,
high levels of marital conflict, and even the destructive
effect of the boys’ behavior on what was already a poor
marriage.
(42) Cognitive style is also a factor. Children
who can “reframe” the divorce in a positive way
do better than those who don’t (Radovanovic, 1993).
Similarly, those children who appraise the divorce with a
sense of lack of control, a sense of loss, feelings of helplessness,
and self-critical feelings, fare much more poorly following
divorce and/or post-divorce conflict (Lengua & Sandler,
1996; Sandler, Tein & West, 1994).
(44) P.A.S also has many features in common
with folie a deux a more dependent and submissive individual
takes on the world-view of a more dominant individual due
to dependency, enmeshment, concern for the emotional distress
of the dominant person, and poor capacity to reality test.
The disorder is most often improved by separation of the parties.
The most common parent-child duo in cases of folie a deux
are mother-daughter pairs (Deutsch, 1938; Gralnick, 1942;
Dewhurst & Todd, 1956; Soni & Rockley, 1974; Sacks,
1988; Munro, 1986; Brooks, 1987; Dippel, Kempel, & Berger,
1991, Mentjoux, van Houten, & Koolman, 1993).
(45) P.A.S. is most often a problem of mother-daughter
pairs (Dunne & Hedrick, 1994); mother-son alignments (Wallerstein
& Kelly, 1980b); or mother-daughter and mother-son pairs
equally (Racusin, Copans, & Mills, 1994).
(46) Clinicians and researchers differ as to
suitable treatments or P.A.S. Some lean toward swift intervention
through the courts in extreme cases and separation of the
enmeshed mother-child pair (Gardner, 1992; Cartwright, 1993;
Lund, 1995; Kopetski, 1991). Others strongly oppose separation
of the mother-child pair (Garrity & Baris, 1994; Johnston
& Roseby, 1997). All agree with Dunne & Hedrick (1994)
that traditional methods of treatment are ineffective in severe,
intractable cases.
(48) Research studies have established that
parents involved in protracted post-divorce disputes have
some ersonality/cognitive traits in common. They have poor
impulse control, are needy and demanding, have poor problem
solving skills, and deal with highly emotional situations
through the use of denial, blame, and defensiveness. They
have difficulty taking another person’s perspective
and have poor interpersonal skills. They are more self-serving
and less child-centered. (Ehrenberg, Hunter, & Elterman,
1996; Hoppe & Kenney, 1994)
