Monogamy gene focus of Karolinska Institute

The Karolinska Institute in Sweden continues to make news with genetic and sex research. Now they come forward with a study in the Proceedings of National Academy of Sciences which finds a link between relationship stability and a gene variant. Here is the KI news release:

Link between gene variant and relationship difficulties
[PRESS RELEASE, 2 September 2008] Scientists at Karolinska Institutet have found a link between a specific gene and the way men bond to their partners. The results, which are presented in the scientific journal PNAS, can lead to a better understanding of such problems as autism and social phobia.
“There are, of course, many reasons why a person might have relationship problems, but this is the first time that a specific gene variant has been associated with how men bond to their partners,” says Hasse Walum, postgraduate student at the Department of Medical Epidemiology and Biostatistics.
He stresses, however, that the effect of this genetic variation is relatively modest, and it cannot be used to predict with any real accuracy how someone will behave in a future relationship.
Hasse Walum and his colleagues made use of data from The Twin and Offspring Study in Sweden, which includes over 550 twins and their partners or spouses. The gene under study codes for one of the receptors for vasopressin, a hormone found in the brains of most mammals. The team found that men who carry one or two copies of a variant of this gene  allele 334  often behave differently in relationships than men who lack this gene variant.
The incidence of allele 334 was statistically linked to how strong a bond a man felt he had with his partner. Men who had two copies of allele 334 were also twice as likely to have had a marital or relational crisis in the past year than those who lacked the gene variant. There was also a correlation between the mens gene variant and what their respective partners thought about their relationship.
“Women married to men who carry one or two copies of allele 334 were, on average, less satisfied with their relationship than women married to men who didnt carry this allele”, says Hasse Walum.
The same gene has been previously studied in voles, where it has been linked to monogamous behaviour in males.
“The fact that the corresponding gene has proved important for similar behaviour in voles makes our findings even more interesting, and suggests that the thoroughly studied brain mechanisms that we know give rise to strong bonds between individual voles can also be relevant to humans”, Hasse Walum concludes.
The team hopes that greater knowledge of the effect of vasopressin on human relations will one day give science a better understanding of the causes of diseases characterised by problems with social interaction, such as autism.

Genetic variation in the vasopressin receptor 1a gene (AVPR1A) associates with pair-bonding behavior in humans, PNAS Early Edition, 2-5 September 2008.

Ah, the mysteries of human behavior. I think there is probably something to this. Men who look to bonding problems with their parents for the reason they do not feel connected to their mates might better look elsewhere. None of this is destiny but it makes some sense that the mechanisms underlying bonding are variable in their application due to DNA. Furthermore, none of this suggests that monogamy is not valuable or attainable — it just means some must work harder at it.

McCain-Palin, 2008


Looks like the Veepstakes goes to Sarah Palin…
The AP is not so sure, but all signs point that way…
CNN says it is so.
Here is what the McCain campaign is saying about the pick:

My Friends,
I am honored to announce that I have chosen Governor Sarah Palin of Alaska as my choice for the Republican nominee for Vice President. As a father with three daughters, I can’t express how proud I am to choose the first female Republican Vice-Presidential nominee.
Sarah Palin is a trailblazer and a reformer. As the first female governor of Alaska, she challenged a corrupt system and has been a tireless advocate for reform – passing a landmark bill on ethics reform. She has taken on the old politics in Alaska and reformed the state’s energy industry. She rejects wasteful pork barrel spending. She’s fearless – exactly the type of leader I want at my side and the type of leadership we will bring to Washington.
My friends, together Sarah Palin and I make the strongest presidential ticket and I know that she joins me in asking for your support as we head into our Convention week in Minnesota. We’re shaking things up in this campaign – and Governor Palin and I are ready to bring real reform to Washington.

From the FOXNews account:

Born in Sandpoint, Idaho, on Feb. 11, 1964, Palin moved with her family at the age of three months to Wasilla, Alaska, though she returned to her birth state to attend the University of Idaho, where she studied journalism and graduated in 1987 with a bachelor’s degree.
Palin is the mother of five children — Bristol, Willow, Piper, Track and Trig, who was born in April with Down syndrome.
She grew up in Wasilla, just outside of Anchorage, played on Wasilla’s state champion girls’ basketball team in 1982, wore the crown of Miss Wasilla in 1984 and competed in the Miss Alaska contest.
She began her professional career as a television sports reporter, but after she married her husband, Todd, she helped run his family’s commercial fishing business. Other professional endeavors included the ownership of a snow machine, watercraft and all-terrain-vehicle business.
She ran for Wasilla City Council in 1992, winning her seat by opposing tax increases. Four years later, she was elected mayor of Wasilla at age 32 by knocking off a three-term incumbent.
At the end of her second term, party leaders encouraged her to enter the 2002 race for the Republican nomination for lieutenant governor. Against veteran legislators with far more experience, Palin finished second by fewer than 2,000 votes, making a name for herself in statewide politics.
Palin had exceptionally high approval ratings through mid-2007 and received high marks for her accessibility, a change from Frank Murkowski’s administration.

The information about Sarah Palin is pouring in (Did someone give a speech last night?). Here is an interview with Newsmax where she discusses social and energy issues.
And a long Anchorage news article regarding her run for Gov.

NARTH fact sheet: Female homosexual development, Part 2 – Child sexual abuse

In the first part of my review of the NARTH fact sheet on female homosexuality, I critiqued the empirical foundation of the NARTH theories about causation of female same-sex attraction.
In this post, I examine the statements regarding sexual abuse and causation. It may be surprising to some observers to read this:

Although sexual abuse does not directly cause same sex attraction, studies report male sexual abuse of lesbians as generally being twice as high as of heterosexual women, that is, on average, 50 percent of lesbian women report a history of sexual abuse. (26, 27) If family relational dynamics and gender nonconformity are already in place, sexual abuse can clench the direction of detachment, gender insecurity, and disidentification possibly leading to same sex attraction.

The article does not specify sexual abuse as a direct cause of same-sex attraction. However, the author does believe that being abused as a child can push a girl in that direction if she suffered detachment from her mom and was gender nonconforming as a child.
I checked the references offered by NARTH for the assertion that sexual abuse of lesbians by men are “twice as high as of heterosexual women” and that “50 percent of lesbian women report a history of sexual abuse.” I cannot find these statistics.
Reference 26 is to a survey of lesbians, gay men, and bisexuals and their siblings by Balsam, Rothblum, and Beauchaine in 2005 (see reference list at the end of the post). In this study, the authors used a convenience sample of same-sex attracted people and asked them to recruit a sibling to participate. They reported childhood sexual abuse (CSA) prevalences for straight (30.4%), lesbian (43.6%) and bisexual (47.6%) female participants. The effect size of these differences are very low, between 1-2%.
Reference 27 is to research reported in the Journal of Gay and Lesbian Social Services by Hughes and team in 2000. In this study, forty-one percent of lesbians reported CSA while among straight women the number was 24%.
The NARTH article adds:

Sexual abuse can be emotional, verbal, or physical. A girl who is sexually objectified though inappropriate sexual comments, denied age appropriate privacy or whose father has voyeuristic tendencies, has been sexually violated without ever being touched. (28, 29)

I do not contest that the paternal behaviors referenced here are inappropriate and potentially harmful. However, the references for these statements does not provide research support for the statements about CSA. One, (29) is not to a research study but to a book for a lay audience by Janette Howard and the other (28) is a 1991 research study by Peters and Cantrell which failed to discriminate lesbians and straight women via abuse variables.
There are some discouraging percentages in this literature but they apply to women overall, with a moderate elevation for lesbians. Here is what I found in a brief PsychLit search.
Table CSA
A look at the table demonstrates that most research finds a modest elevation for lesbians but does not demonstrate the 50% figure nor support for the conclusion that prevalences are twice as high for lesbians as straight women. Prevalences are sadly and unacceptably high for all women.
I fear that this fact sheet will become basis for inaccurate information spread by sexual identity and ex-gay ministries. Whatever the reason for the differences, it cannot be helpful to paint a false picture. Sexual abuse is a trauma that often requires therapeutic and spiritual intervention but whether it is involved in the origins of same-sex attractions continues to be an open question.

A conservative defense of sex research

During the Saddleback Civil Forum, if Rick Warren had asked the candidates about funding sex research, it might have gone like this.
Warren: What is your position on researching sex?
McCain: (with resolve and without hesitation) – Missionary!
Obama – Uh, well, it depends on how you define “sex” and “research.” Scientifically and politically, it is above my pay grade to determine what my position is in that arena.
Pure fiction, of course. I doubt sex research will come up in this year’s election. However, the topic has become a concern to some politicians. According to an ABC News report, “Sex, massages and taxpayer dollars,” some legislators are bothered by some NIH grants to universities to study sexuality. Some of Michael Bailey’s work aroused more than curiosity. To wit:

A few years ago, NIH gave a $147,000 grant to a Northwestern University psychology professor who was paying women to view pornography while a device measured their sexual responses.
That study didn’t go over too well in the halls of Congress.
Arizona Rep. Jeff Flake was among 20 Republicans to sign a letter to NIH’s director asking for an explanation for why taxpayer money was going for such a study. They called it “a bizarre spending decision.”
Today, Flake believes Congress has failed to properly oversee NIH and its spending.
“It’s Congress’ job to set guidelines for how NIH and other agencies spend taxpayer money and then exercise oversight to ensure that those guidelines are being followed. “However, over the last several years, Congress has neglected its oversight function,” Flake’s office told ABC News. “It’s difficult for Congress to criticize NIH for wasteful grants when Congress itself is earmarking billions of dollars every year on similarly wasteful pet projects.”

I have to disagree with Rep. Flake and his colleagues. As a social conservative, I am very interested in research which helps us better understand how sexuality works. Regarding sex research, I think Guggenheim Fellow Alice Dreger raises a valuable point when she argues:

What about the studies that look into things like which kind of pornography stimulates women versus men? Useless and prurient? I don’t think so. I know this sort of research horrifies conservatives, but they should really wake up to the fact that research into sexual stimulation can actually help promote family life by helping married couples understand how to have satisfying sex lives within the context of monogamy. (Is it better that a guy cheat on his wife with a prostitute, or better that he learn a vibrator and some massage might make his wife a lot more receptive? I vote for the latter.)

Of course, an unexciting sex life does not force anyone into seeking prostitutes, but I think Dr. Dreger’s argument should be taken seriously. Counselors know that otherwise solid couples, yes even very religious couples, are not exempt from sexual questions and concerns. Better that counselors are armed with good science on sexuality than the latest issue of Cosmo. Reading the Song of Solomon, while quite, uh, interesting, might not be enough to help overcome issues which would benefit from basic information. Lay people might be surprised that research is needed to better understand sex and attraction, but such science is important for reasons that might not seem apparent.
In my work, I have found the research coming out of the Bailey lab to be very helpful. His research informs my work with people on a regular basis. I often consult with heterosexually married, same-sex attracted men who wish to maintain their marriage. Bailey’s (and other researchers’) brain research, for instance, provides significant insight into how the brain responds to sexual cues. This is valuable information for those who seek insight into why they respond as they do. And many of them use this information to pursue their values and beliefs to avoid sex with men and enhance their marital adjustment with their wives.
I guess the bottom line for me is that funding sex research doesn’t mean advocating an anything-goes stance toward sex. Studies done solely for prurient interests should be questioned, but basic science of sexual attraction and arousal can have positive, and even conservative, applications.

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.
