International Day Against Homophobia, Transphobia and Biphobia (IDAHOT)

A worldwide Celebration of Sexual and Gender Diversities, May 17 

IDAHOT Commemoration and Call to Action

On May 17, 1990, the World Health Assembly of the World Health Organization approved the International Statistical Classification of Diseases and Related Health Problems (ICD 10), which no longer listed homosexuality as a diagnosis. Launched in 2004, the International Day Against Homophobia commemorating that day has become a global occasion to educate about lesbian, gay, bisexual and transgender (LGBT) people, and to advocate for sensible public policies regarding LGBT people.

Now called the International day against Homophobia, Transphobia and Biphobia (IDAHOT), the observance has caught on widely as an international opportunity for individuals, groups and organizations anywhere to do anything they wish to mark the day. The IDAHOT website features numerous action ideas and reports detailing the wide range of activities planned for this year and from years past.  

IDAHOT Theme for 2018: Alliances for Solidarity 

APA Co-Sponsors Congressional Briefing May 17, 3-4:30 p.m.

Each year has a different theme. The theme for 2018 is Alliances for Solidarity, to recognize that progress on LGBT issues requires building and sustaining partnerships. 

To mark the day this year, APA is partnering with the Center for American Progress and the Fenway Institute to conduct a public Congressional briefing on Capitol Hill titled Rolling Back Progress: How Shifts in Federal Policy are Hurting Lesbian, Gay, Bisexual and Transgender Americans (PDF, 187KB), which will be led by Clinton W. Anderson, interim executive director for the Public Interest Directorate and director of the Office on Sexual Orientation and Gender Diversity. If you would like to attend, please RSVP. 

Speakers will focus on three main areas by first reviewing the current political landscape, including supportive and discriminatory bills and actions emanating from Executive Branch Agencies, with a focus on civil rights and data collection. They will then explain psychological and public health evidence on the harmful physical and mental health effects of discriminatory policies and the protective effects of supportive policies. And finally, they will suggest specific policy recommendations to limit stigma and benefit the health of sexual and gender minorities. 

The briefing open to the public is Thursday, May 17, 3-4:30 p.m., Rayburn House Office Building, Room 2103. 


In keeping with this year’s theme, this section highlights work in which APA has been involved to produce resources that are the result of partnering with other psychological and non-governmental organizations, both domestically and internationally.

Respect Workshop and Toolbox to Promote Healthy LGBT Youth 
The Respect Workshop is designed to help school professionals assist lesbian, gay, bisexual, transgender and queer (LGBTQ) students in coping with their distinctive challenges, promote safe school environments that nurture healthy and successful students, and motivate all students to prevent HIV, STIs and pregnancy. 

The Toolbox to Promote Healthy LGBT Youth includes supplemental resources to help school professionals support LGBTQ students. Organizations with which APA partnered to develop this resource were the American Counseling Association, the American School Counselor Association, the National Association of School Nurses, the National Association of School Psychologists, and the School Social Work Association of America.

What Can Psychologists Do?

IDAHOT creates a valuable opportunity for psychologists to engage in public education activities. The APA's Office on Sexual Orientation and Gender Diversity offers a range of resources from informational brochures to APA policy statements to comprehensive reports that can be used to support your efforts. These resources can be used not only on May 17, but year-round. Please let the Office on Sexual Orientation and Gender Diversity know of activities you decide to undertake and contact the office if you have questions or need technical assistance.
