Study Design and Objectives

Following our formative research, the GEAS launched a longitudinal study that will follow the experiences of over 15,000 adolescent boys and girls ages 10-14 years old on five continents for up to five years.

The GEAS will conduct two types of research.

OBSERVATIONAL RESEARCH: GEAS sites function as observational research studies among approximately 1,400 adolescents.
These studies provide insight into the evolution o f gender norms over time and the impact of gender norms on key behavior and health outcomes.

IMPACT EVALUATION OF INTERVENTIONS: In some sites, the GEAS survey is used to evaluate the impact of interventions aimed at shifting the trajectory toward greater gender equality. Intervention sites enroll a larger sample of adolescents, equally divided into intervention and control arms.

The GEAS Survey

The GEAS survey instrument is comprised of three measures: a ten module health instrument, a vignettes-based measure of gender equality and a measure of gender norms. Together, these three components assess a range factors and outcomes in adolescence including: gendered norms and processes; adolescent empowerment; risk and protection; exposure to violence and adversity; cohesion and connectedness among peers, family, school, neighborhood, and community; and a range of health outcomes.
