The problem
Intervention: Planning Health in School (PHS-pro) - a behavioural change programme based on the Transtheoretical Model that integrates nutritional literacy and builds problem-solving and decision-making skills through educational modules and participatory activities
Who it was tested with: 240 children aged 10-12 in a suburban school in Porto metropolitan area, Portugal.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Children (n = 240, ages 10–12) of one large suburban school in Porto's metropolitan area (Portugal) were evaluated throughout PHS-pro implementation during one school year in a repeated time–series design. Children's outcome evaluations were conducted through seven 3-day food records for nine eating behaviour, documented after each learning module and through participatory activities which analysed attitudes, preferences and expectations." The study measured the same children over time with multiple data points but lacked a comparison group to attribute causality definitively.
Single school setting with no comparison group limits causal inference; no follow-up data on sustainability of changes; repeated food records may introduce recall bias; limited demographic or socioeconomic information about the population studied.
