New study casts doubt on older brother hypothesis and reparative drive theory

A new study by Andrew Francis of Emory University in the Journal of Sex Research casts doubt on both the fraternal birth-order effect and reparative drive theory.
Here is the abstract:

Using a nationally representative sample of young adults, I identify the family-demographic correlates of sexual orientation in men and women. Hence, I test the maternal immune hypothesis, which posits that the only biodemographic correlate of male homosexuality is the number of older brothers, and there are no biodemographic correlates of female homosexuality. For men, I find that having one older brother does not raise the likelihood of homosexuality. Although having multiple older brothers has a positive coefficient, it is not significant. Moreover, having any older sisters lowers the likelihood of homosexual or bisexual identity. For women, I find that having an older brother or having any sisters decreases the likelihood of homosexuality. Family structure, ethnicity, and education are also significantly correlated with male and female sexual orientation. Therefore, the maternal immune hypothesis cannot explain the entire pattern of family-demographic correlates. The findings are consistent with either biological or social theories of sexual orientation.

The sample is large and the measures of sexual orientation, while brief, cover behavior and attractions. Here is more on the sampling:

I use the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative study of adolescent health in the United States (Udry, 2003). Adolescents in grades 7 through 12 were initially interviewed in 1995 and 1996 (Waves I and II) and were reinterviewed in 2001 (Wave III). The sample size of male respondents is about 5,000, and the sample size of female respondents is about 5,600. Table 1 displays summary statistics. At Wave III, all respondents in the sample were 18 years old or older. About 88% were between the ages of 20 and 24.

Sexual orientation was assessed with this item:

‘‘Choose the description that best fits how you think about yourself: 100% heterosexual; mostly heterosexual, but somewhat attracted to people of your own sex; bisexual, that is, attracted to men and women equally; mostly homosexual, but somewhat attracted to people of the opposite sex; or 100% homosexual.’’

As noted, the theory that the likelihood of any homosexuality is enhanced via more older brothers is not supported by this large, representative sample. In addition to a look at older brothers, Francis also examined other family demographics. Although unrelated to homosexual behavior or attraction, having older sisters was associated with a slightly reduced identification as less than 100% heterosexual. This finding contrasted with the 2002 Bearman and Bruckner study which found an elevation in homosexual romantic attraction for fraternal twin males with a female twin.
For females, Francis found that having siblings decreased slightly the likelihood of most same-sex outcomes. None of the correlates predict sexual orientation well. In every case, the size of the differences were trivial. With large samples, one does not need a large difference between groups to attain statistical significance.
Francis also examined family structure and found more trivial associations. For instance, he found a 3.8% increase in the likelihood of ever having a same-sex sexual partner among those who did not live with either parent. In contrast to reparative theory expectations, he reported that identifying as less than 100% heterosexual for males was associated with living with only dad. No romantic attraction or same-sex behavior was reported for males living with only mother.
There were other factors which Francis reported but the real take home point from this study is how little any of these variables predict sexual orientation. This study undermines reparative drive theory due to the unremarkable performance of the parental variables to predict orientation. One would expect to find great differences between male heterosexual participants and same-sex attracted participants if fathering/mothering were crucial to male sexual orientation as Joe Nicolosi teaches. In fact in this YouTube video, Nicolosi says that the main factor in the development of male homosexuality is a distant or hostile father.
The Francis article finds very little predictive power in family dynamics of any kind. There is no predictive power at all for those whose parents are separated. Living with dad should insulate against a homosexual outcome and living with mom alone should enhance the likelihood of same-sex attraction and/or behavior. In this sample, it does not.

Lisa Diamond: NARTH distorts my research

Today’s Salt Lake City Tribune published an article which brings the private feud between University of Utah professor Lisa Diamond and the National Association for the Research and Therapy of Homosexuality (NARTH) into public view. Diamond went on camera for Wayne Besen in October to complain about NARTH’s use of her research but this article brings the dispute out of the advocacy realm and into the Salt Lake City community. An added significance of the SLC Tribune raising this issue is the presence of NARTH’s Dean Byrd and Dave Pruden in Salt Lake City.
The article begins:

A national group that advocates “treatment” of homosexuality is being criticized for allegedly distorting a Utah researcher’s work to advance the theory that people choose their sexual orientation – a controversial notion rejected by mainstream psychology.

To be sure, at least one NARTH document I have reviewed does use Diamond’s research to mislead readers, but I do not think NARTH as an organization promotes the idea that sexual orientation is a conscious choice. Rather, the reparative notion is that same-sex attraction derives from faulty parenting and not conscious choice.
I suspect the position paper on female homosexuality I critiqued is at issue when reporter Brian Maffly writes:

Lisa Diamond, a University of Utah psychologist whose sexual identity studies suggest a degree of “fluidity” in the sexual preferences of women, said in an interview Tuesday that the National Association for Research & Therapy of Homosexuality, or NARTH, misrepresents her findings. Position papers, some penned by NARTH president A. Dean Byrd, an adjunct professor in the U.’s Department of Family and Preventive Medicine, point to Diamond’s research as evidence that gays’ sexual orientation can be straightened out through treatment – much to Diamond’s dismay.

The NARTH position paper on female homosexuality says this about Diamond’s work in a section on the “Fluidity of Homosexuality Attraction.”

These findings support the research of Dr. Lisa Diamond who concluded, “Sexual identity was far from fixed in women who aren’t exclusively heterosexual.” After following 80 non-heterosexual young women (lesbian, bisexual and unlabeled) over a two-year period, Dr. Diamond found that half of the women “reported multiple changes in sexual identity, and nearly one fourth of lesbians pursued sexual contact with men.”

The NARTH author confuses matters by first saying,

As mentioned, many researchers attest to the reality of female sexual fluidity. This does not directly translate into proof that any woman can easily change or alter her same sex attraction.

However, following the Diamond reference is a statement that twists the concept of spontaneous sexual fluidity for some women in a way that has Diamond upset.

The degree to which a woman can or will experience change will be uniquely determined based on her history and motivation to do so.

This is a non-sequitur. While fluidity has been described over time by research participants, the cause for the fluidity is an open question. The research identified by the NARTH “fact sheet” does not allow this conclusion. We have no idea for any given woman why change occurs. Diamond correctly criticizes NARTH for misusing her work in this way. Maffly continues,

Diamond, who has never met [NARTH president Dean] Byrd, said in an interview that NARTH “cherry picks” findings or references from her work that appear to support their position.

NARTH’s responds as has become typical. They claim they are just interpreting the data differently.

[NARTH founder and past-president, Joe] Nicolosi did not respond to an interview request and Byrd claimed he did not know why Diamond, a fellow U. faculty member, took umbrage with NARTH’s citation of her work.
“NARTH’s view is that people can adapt any way they want and there is freedom of choice,” Byrd says. “If it says ‘fluidity’ it says ‘fluidity.’ How you interpret it is something else.”

The reporter Maffly can be forgiven for his opening lines about NARTH promoting choice given Byrd’s way of discussing the matter. I suspect Byrd means choice of behaviors. Whatever he means by freedom to choose, he is wrong to say there is no guidance from Diamond’s research about how to interpret ‘fluidity.’ A review of her most recent book, Sexual Fluidity, makes clear that some of the women retained their same-sex attraction while discovering opposite-sex attraction. Some women actively fought the change of attraction but resigned themselves to heterosexuality. Her work does not support the statement about change being associated with history or motivation.
UPDATE – 8/31/09: The Salt Lake City Tribune article has been archived and is not available at that link now. Here is a newswire article on the same topic. A UPI story is for some reason archived on this Moldova gateway.
Also, here is an example where NARTH members misused Michael Bailey’s research.

Narth fact sheet: Female homosexual development

Narth recently released a fact sheet that is relevant to some information I posted regarding reparative therapy research.
The paper has some bright spots but overall reverts to the same reparative drive theoretical formulation for which NARTH is known. On the NARTH website, Dean Byrd praises the APA for taking a more nuanced perspective toward causation and same-sex attraction, but in this paper, NARTH does not follow the APA’s lead.
The paper begins by attempting to make a case for sexual fluidity by quoting mainstream researchers. I suspect researchers such as Michael Bailey, Ken Zucker, and Lisa Diamond will be uncomfortable with how their work is integrated in this piece. The unnamed NARTH author then suggests that the reason research supporting developmental causes is minimized today is due to bias against these findings. For some reason, Rogers Wright is quoted in this context. However, Rogers is referring to psychotherapy and not research on causal factors. Regarding the research on environmental factors, the paper says:

There is, in fact, a wealth of older research identifying many common developmental, temperamental and family patterns connected to homosexuality. This research has never been scientifically refuted.

The citations for this statement are a 10 year old paper by Mark Yarhouse and a 15 year old book by Goldberg. Yarhouse and I were making a case for reorientation therapies broadly speaking several years ago. However, our model now calls for a cautious and realistic assessment of the literature on change and causal factors. Our sexual identity therapy framework is based, in part, on the observation that we do not know what causes sexual orientation in any general sense, nor do we know what, if any, factors might lead to fluidity. Our model stresses value congruence rather than change in orientation.
In fact, “the older research” has been addressed as inadequate to explain the complexity of sexual orientation (e.g, Bell, Weinberg & Hammersmith, 1981; see this post about Fisher and Greenberg’s review of psychoanalytic literature, and this post as well). In the context of the NARTH claim, I would like to ask anyone to produce the three best studies which support the “common developmental, temperamental and family patterns connected to homosexuality.” I am serious about this. Preferably I would like proponents to post them in a comment for discussion but these references may also be emailed to me.
Based on this lead, I expected the author to make a case that the observation of sexual fluidity for some meant that therapy could be helpful in promoting change of orientation. However, the paper did not quite come to that conclusion, saying

The concept of sexual fluidity, defined as the spontaneous evolution or transformation of one’s sexual preferences, is different from the concept of changeability involving intentional effort directed towards altering or changing one’s sexual preferences. As mentioned, many researchers attest to the reality of female sexual fluidity. This does not directly translate into proof that any woman can easily change or alter her same sex attraction. It does however confirm that sexual feeling and behaviors are not absolutely immutable or unchangeable. The degree to which a woman can or will experience change will be uniquely determined based on her history and motivation to do so.

While I appreciate the distinction between spontaneous fluidity and intentional attempts to change, I do not think significant evidence has established that motivation is a catalytic component for such fluidity. Certainly some women testify that they sought change and experienced it but others sought change and did not. We do not know that change is determined by “history and motivation.” This sentence almost sounds like change is related to motivation in some dose-dependent manner – the more motivation, the more the change. This can be a very frustrating and defeating message for people who are quite motivated and yet continue to experience same-sex attraction.
The paper then indicates via quote from George Rekers that gender nonconformity and a feeling of being different is associated with adult homosexuality. This is the same data Bem appeals to in crafting his erotic becomes exotic (EBE) theory. Although less so for females than males, these are true observations. In 1995, Bailey and Zucker summarized the research on gender nonconformity and adult sexual orientation this way:

As our analyses demonstrated for both men and women, research has firmly established that homosexual subjects recall substantially more cross-sex-typed behavior in childhood than do heterosexual subjects. By rough criteria, effect sizes were large for both men and women. Indeed, they were among the largest effect sizes ever reported in the realm of sex-dimorphic behaviors.

However, instead of stopping there, the NARTH paper leaves research and goes to theory and clinical anecdote by suggesting:

Typical in the history of women with same sex attraction are failures of attachment with the mother resulting in disidentification (rejection as role model).

The research cited does not suggest that gender nonconformity leads to failures of attachment, but the lay reader might not catch the shift from data to theory. The NARTH paper cites no studies which demonstrate higher levels of attachment failures, nor higher levels of disidentification with mother. The reference is to a speech given by NARTH Board Member, Janelle Hallman at a NARTH conference.
Then Elizabeth Moberly’s theories are referenced as evidence. Dr. Moberly, who was not a clinician nor did research on sexual orientation, proposed the basic reparative drive theory which holds:

…that the homosexual-whether man or woman has suffered from some deficit in the relationship with the parent of the same-sex: and that there is a corresponding drive to make good this deficit-through the medium of same sex or “homosexual” relationships.”

The NARTH paper also claims poor fathering, marital distress and sexual abuse play a role in lesbian development. Feminist researchers are quoted out of context to make a point about the need for positive attachments among women. However, the reader is not informed that no research has linked poor mother-daughter attachments to later lesbian development
In a second part of this critique, I will take the sexual abuse statistics separately. Let me say now that I reviewed the studies referenced, and I cannot determine how the NARTH author arrived at a statistic of 50% of lesbians, on average, have been sexually abused. One must take into account representative sampling when offering such data. I am looking for something more recent but one 1994 study using a representative sample of lesbians found that 21% of lesbians reported sexual abuse as a child.
The NARTH paper concludes this way:

Women who deal with same sex attraction, possess a history of disindentification with their mothers, and therefore with their femininity. This leads to a longing for connection with the feminine that becomes sexualized in adolescence or adulthood. Without a secure attachment to mother, she fails to identify with mother as a female role model losing the opportunity to develop trust and a healthy gender identity. Because of an empty or distorted view of her feminine self she has an inability to connect in a healthy way with other girls. Her sexual development is arrested.

It is possible that the NARTH author believes that since the paper mentions biological, psychological and social factors in the same paper that a “bio-psycho-social model of causation” is being advanced. However, a review of the paper finds no such model where these factors are integrated with research support.
Despite the use of some research studies in this paper, the conclusion leaves data and moves to the reparative drive theory first articulated by Elizabeth Moberly. Back in March, I posted about Dean Byrd’s review of the APA paper on sexual orientation. Then I wondered

…when NARTH would make an APA-like statement about theorized environmental factors such as child abuse and same-sex parenting deficits. What if NARTH acknowledged “what most scientists have long known: that a bio-psycho-social model of causation best fits the data?” Wouldn’t there be a need for a statement cautioning readers of their materials that evidence for parenting playing a large or determining role is meager? Paralleling Dr. Byrd’s assessment of the APA pamphlet, shouldn’t NARTH say with italics, “There is no homogenic family. There is no simple familial pathway to homosexuality.”

Still wondering.

Interviews with Joseph Nicolosi

Here is a three part interview with Joseph Nicolosi, who discusses his views of homosexuality and his approach to therapy.
Part One
Part Two
Part Three
I don’t agree with the basic theory but I wanted to provide the links for those of us who study the various approaches. When I study an approach, I like to have the current information, and these appear to be very recent.
Let’s have an open forum on this…

Mankind Project clarifies stance on reparative therapy

Within the last day or so, Mankind Project members received an email from Executive Director, Carl Griesser with an alert to a new feature on the MKP website.

…the next time you visit www.MKP.org you will find a rainbow flag with the word Friendly superimposed as a navigation button linked directly to a slightly modified version of the reparative therapy statement. The Executive Committee and our IT Team believe this is an effective way of indicating our welcoming attitude to all men, while making the statement easily accessible to the public.

Click on the link and you will find the following article titled Sexual Orientation & the Mankind Project:

· The ManKind Project creates trainings and circles in which men are invited to discover their deepest truths.
· We welcome men of all sexual orientations: gay, straight, and bisexual, as well as those who identify as having unwanted same sex attraction, to do their own work as they define it, to respect the identity and value of others, and to take responsibility for the impact their words and behaviors have on others.
· We support each man in pursuing his path to deeper authenticity. We do not provide therapy nor endorse any particular therapy, including reparative therapy. Any group or organization that states or implies otherwise does so without our permission.
· We do not, and will not, attempt to change a man’s sexual orientation.
· We stand firm in support of gay and bisexual men. We support men who believe that homosexuality is a normal part of the spectrum of human sexuality and of mature masculinity.
· We will not tolerate proselytizing for any religion or belief and do not tolerate discrimination on our trainings or in our communities. We support our training and community leaders in identifying and challenging discriminatory language and behavior.

I provided a link to this statement in a previous post. Essentially, some reparative therapy clients/therapists were recommending the New Warriors Training Adventure to same-sex attracted men as a means of enhancing their sense of masculinity. Reparative therapists believe male same-sex attraction derives from a sense of distrust of men and a disconnection from natural masculinity. Via the reparative drive, he sexualizes his desire for masculine closeness and seeks homosexual relationships. Get a man feeling all masculine and his SSA disappears. Perhaps one of the clearest statements of this hypothesis and the proposed remedy is David Pickup’s the Workout program.
Mr. Pickup recommends the New Warriors Training Adventure and notes on his website that he serves as training coordinator of the Los Angeles branch of the Mankind Project. This is the branch which hosted Joseph Nicolosi, Narth co-founder and father of reparative therapy, at a training session in 2005. This session was quite controversial and eventually led to the MKP statement.
The email to MKPers provided this rationale for the new rainbow link:

Men,
As many of you are aware, the Project Council approved a Position Statement on Reparative Therapy in February 2007. Based on initial text prepared by Jim Mitchell, I prepared a statement which was then revised by a group of gay, bi, and straight men, and men who identify as having Unwanted Same Sex Attraction (USSA). We decided that it was necessary to take this stand because many men were being referred to the NWTA by reparative therapists and groups who had little or no experience with MKP (as well as by some reparative therapists and USSA men who had been through the training.) It was our intention to clarify for ourselves and for these men what they can expect if they attend our trainings. I sent the statement to the reparative therapists and groups I knew about, and have continued to do so when I learn of others. I asked organizations which implied on their websites that MKP offered or supported reparative therapy to remove such statements and any links to our website. Some complied with the request, though not all.

I got a chuckle out of this sentence: “It was our intention to clarify for ourselves and for these men what they can expect if they attend our trainings” since the MKP is so secretive about what men can expect. In any case, I believe it is valuable for MKP to indicate to men that they do not adhere to the masculinity enhancement model of reparative therapy for men who might be encouraged by reparative organizations/practitioners to seek NWTA for that purpose.
