Prejudice is common against people who...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Background:

Homophobic and transphobic beliefs contribute to bias-based harassment among youth in the USA.
There is a critical need for interventions to address these harmful beliefs and promote inclusive school environments.

Purpose of the Study:

To evaluate the impact of an inclusive, comprehensive sex education program, High School FLASH, on homophobic and transphobic beliefs among adolescents.
To examine program effects across different student subgroups, including straight cisgender youth and LGBTQ+ youth.

Main Methods:

A randomized controlled trial involving 20 schools across two U.S. regions.
Schools were randomized to implement either the High School FLASH curriculum or a comparison curriculum.
Ninth and 10th-grade students completed surveys at baseline, 3 months, and 12 months post-instruction; multilevel linear regression models were used for analysis.

Main Results:

Students participating in High School FLASH demonstrated statistically significant reductions in homophobic and transphobic beliefs compared to the control group at both 3- and 12-month follow-ups (p < 0.01).
The program showed significant positive effects for straight cisgender youth at both follow-up points (p < 0.01 and p = 0.05).
For LGBTQ+ youth, the reduction in harmful beliefs reached statistical significance at the 12-month follow-up (p = 0.01).

Conclusions:

Inclusive, comprehensive sex education programs, such as High School FLASH, are effective in reducing homophobic and transphobic beliefs.
These programs contribute to fostering safer and more inclusive school climates for all students by mitigating bias.
Evidence supports the role of targeted educational interventions in preventing bullying, violence, and victimization related to sexual orientation and gender identity.
