New SHTAC research article on school-based programmes to prevent sexually transmitted infections

Published: 6 February 2014

A new article on methods to evaluate the outcomes and processes of school-based behavioural interventions to prevent sexually transmitted infections has just been published.

The methodological article, published in Health Education Research, was based on a systematic review of skills-based behavioural interventions to prevent sexually transmitted infections and promote sexual health among young people in schools. The article discusses how process indicators can complement outcomes as part of a comprehensive explanatory evaluation framework, to better explain why interventions may or may not work.

Synthesis of the findings of the process evaluations in the systematic review identified a range of factors that might explain outcomes, which were organised into two overarching categories: the implementation of interventions, and student engagement and intervention acceptability.  It is recommended that process indicators such as these be assessed in future evaluations of school-based sexual health behavioural interventions, for example, as part of a logic model.

The research was conducted in collaboration with the EPPI-Centre, and was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme. The full systematic review and economic evaluation is freely available in the NIHR Journals Library.
