Evaluating school based comprehensive sexuality education using non randomized cluster design study

Existing evidence demonstrated the effectiveness of Comprehensive Sexuality Education (CSE) in providing adolescents with rightful and appropriate information to improve knowledge, attitudes, and behaviours about sexuality. However, there is no consensus on the optimal methodological approach to evaluate CSE interventions. Here we propose a protocol to assess the outcome of a standardized evaluation strategy on adolescents’ knowledge about sexuality. This research is part of a national Italian project on school-based CSE (EduForIST), funded by the Italian Ministry of health.
