Science Consistently Shows Conversion Therapy to be Harmful and Ineffective
The Iowa Psychological Association Public Education Committee has the sole purpose of bringing to the public’s awareness psychological research and science in about issues relevant to Iowans. The purpose of this committee is to inform and educate based on scientific research. With that in mind, we share the following regarding the science on sexual orientation and the lack of science supporting sexual reorientation/conversion therapy.
In 1990, Dr. Bryant Welch, American Psychological Association Executive Director stated, “Research findings suggest that efforts to repair homosexuals (sic) are nothing more than social prejudice garbed in psychological accoutrements.” Since then, mainstream medical and psychological health associations have taken unequivocal stances against what is called conversion, reparative, or reorientations therapies due to lack of scientific evidence to support positive impact of these interventions, and the plethora of evidence documenting harm. These organizations include: American Academy of Child & Adolescent Psychiatry, American Academy of Family Physicians, American Academy of Nursing, American Academy of Pediatrics, American Association of Marriage & Family Therapy, American College of Physicians, American Counseling Association, American Medical Association, American Medical Student Association, American Psychiatric Association, American Psychoanalytic Association, American Psychological Association, American School Health Association, American School Counselor Association, American School Health Association, National Association of Social Workers, Pan American Health Organization, School Social Work Association of America, and others.
These organizations, representing the majority of U.S. medical and psychological health professionals, have taken this stance not because of political positioning, but because, as the American Psychological Association (2021) noted:
The APA affirms that scientific evidence and clinical experience indicate that sexual orientation change efforts (SOCE) put individuals at significant risk of harm;
APA encourages individuals, families, health professionals, and organizations to avoid SOCE;
APA affirms that same-gender and multiple-gender attraction, feelings, and behavior are normal variations in human sexuality, being LGBTQ+ is not a mental disorder, and APA opposes portrayals of sexual minorities as mentally ill because of their sexual orientation;
APA opposes making claims that sexual orientation can be changed through SOCE and;
APA, because of evidence of harm and lack of evidence of efficacy, supports public policies and legislation that oppose, prohibit, or aim to reduce SOCE, heterosexism, and monosexism and that increase support for sexual orientation diversity.
These organizations have taken stances validating the inherent worth, dignity, and validity of sexual/affectional orientation due to the lack of conclusive empirical evidence that supports that any one sexual/affectional orientation is less or more mentally and physically healthy. In fact, the data is so consistent, these organizations had no other choice but to take these stances to uphold their own foundations of evidence-based decision making. Those who continue to advocate for reorientation continue to perpetuate the reductionist, bipolarity construct of sexual/affectional orientation that science left behind 50 years ago when the American Psychiatric Association declassified homosexuality as a mental health concern in the Diagnostic and Statistical Manual of Mental Disorders. A review of the history of this decision can be found here.
The faulty assumptions imbued into the claims of reorientation are numerous and include:
- Sexual/affectional orientation is behavior that can be changed. This approach ignores copious evidence connoting the multimodality of sexual/affectional orientation, including identity in research across the world.
- Sexual/affectional orientation is limited LGBQ people. Sexual/affectional orientation is descriptive of all people, but Straight people are not expected to engage in reorientation. Research on what science understands about the development sexual orientation and cultural expression of sexual orientation can be found in the following: Biodevelopment of Same-Sex Sexual Orientation , Biological Research on Development of Sexual Orientation, Human Sexual Orientation, Sexual Orientation, Controversy, and Science, Stability and Change in Sexual Orientation
- Religion condemns LGBQ orientation. Reorientation could be sought for religious choice. However, people who identify as LGBQ do not have to abdicate their right to participate in religious practice. Major U.S religions support LGBQ orientations include: American Baptist Church; Disciples of Christ; Episcopal Church; Metropolitan Community Church; Presbyterian Church, USA; Reform Judaism; Society of Friends; Unitarian Universalist Church; Buddhism, United Church of Christ, Congregational, and others.
- Research supports reorientation therapy. Research supporting reorientation therapy has been criticized for problems with poor methodology, biased participant selection, statistical analyses, and inadequate outcome measures. Unethical behavior, sexual abuse, deception, and theological malpractice are also rife throughout this literature. The confines here do not allow for detailing all of this research, though objective reviews can be found from infinitely wide sources including the Minnesota Department of Health, Cornell University, to the Government of the United Kingdom.
- Straight is the standard. There is a systematic bias toward straight orientation and a faulty mainstay assertion within reparative therapy is that people who are LGBQ are undeveloped, regressed, and fixated. Journal of Personality and Social Psychologyand Behavioral Sciences
- Reorientation therapies only help. An overwhelming number of studies note the harmful impact, ethical violations of, or ineffectiveness of conversion therapy. For a review see J Med Regul. 2016; 102(2): 7–12, and the Oxford Journal of Legal Studies
These are a few of the many faulty and specious assumptions that undergird this movement. The leading national organizations who represent the majority of U.S. licensed medical and psychological providers, clearly state that as there is no illness, there is no cure. Legal prohibitions against such practices, which cannot sufficiently document positive outcomes over risk for harm, exist in 27 states+ D.C. and this number grows annually. It is time, as it is with all medical and mental health matters, to listen to the evidence and move on from practices whose predominant basis is bias, poor science, historical limitations, and societal prejudice.

On behalf of the Diversity and Social Justice Committee, I’d like to share that November 20th is Transgender Day of Remembrance (TDOR), a day to honor the trans and gender diverse (TGD) people who’ve been lost to violence. The first TDOR was in 1999 by trans advocate, Gwendolyn Ann Smith, as a way to memorialize Rita Hester, a transgender woman who was murdered.

Bisexuality Awareness Week is occurring this year September 17-24. This is the 24th year of Bi Visibility Day which has been celebrated on the 23rd of September since its inception in 1999. Bisexuality refers to sexual attraction to those who are of the same/similar gender and to those who are of a different gender. The bisexual community faces an ongoing invisibility issue even within the LGBTQAI+ community. This invisibility is referred to as bisexual erasure and reflects the dismissal, minimization, omission, overlooking of bisexual experiences. Bisexual people face greater health disparities in some areas compared to their lesbian and gay counterparts. There are several reasons for this. One is that bisexual folks may not feel they belong in LGBTQ spaces (because they aren’t “gay enough”) and don’t feel they fit in heterosexual spaces (because they are “straight enough”), which negatively impacts mental health. Another reason relates to healthcare providers forgoing important health screenings and tests based on the gender of their bisexual patients’ partners. For example, a physician may not think it is important to screen a bisexual woman for sexually transmitted infections if they know the patient is partnered with a woman.


June 19, is celebrated as “Juneteenth,” in honor of one of the final acts of emancipation of slaves in the United States. On June 19, 1865, the announcement was made that tens of thousands of African-Americans in Texas had been emancipated. Juneteenth traces its origins back to Galveston, Texas where on June 19, 1865, Union soldiers, led by Major Gen. Gordon Granger landed in the city with news that the Civil War had ended and slaves were now free. The announcement came two-and-a-half years after President Lincoln’s Emancipation Proclamation of January 1, 1863 that had ended slavery in the U.S. However, since that proclamation was made during the Civil War, it was ignored by Confederate states and it wasn’t until the end of the war that the Executive Order was enforced in the South. This day is also known as African American Freedom Day or Emancipation Day.


I was a nontraditional student at my undergraduate and graduate schools. In fact, I sought out psychology to answer specific personal questions as well as questions that I’d encountered in my work as a Franciscan nun. To summarize the content of my wondering mind I’d say at a personal level I wanted to know the following: a) who am I? b) why am I here? c) where do I go after I’m no longer here? From my work with young women in Cameroon I wanted to find out how to heal invisible wounds that manifest as struggles in interpersonal relationships especially in communal living situations. At the time I was thinking that most people can do okay within their families but if you have to interact with others who don’t know you the way family does, you need more.
