Abstract
Background
School-based social and emotional learning interventions can improve wellbeing and educational attainment in childhood. However, there is no evidence on their effects on health-related quality of life (HRQoL) or on their cost effectiveness.
Objective
Our objective was to evaluate the cost effectiveness of the Promoting Alternative Thinking Strategies (PATHS) curriculum.
Methods
A prospective economic evaluation was conducted alongside a cluster-randomised controlled trial of the PATHS curriculum implemented in the Greater Manchester area of England. In total, 23 schools (n = 2676 children) were randomised to receive PATHS, and 22 schools (n = 2542 children) were randomised to continue with usual practice. A UK health service perspective and a 2-year time horizon were used. HRQoL data were collected prospectively from all children in the trial via the Child Health Utility Nine-Dimension questionnaire. Micro-costing was undertaken to estimate the intervention costs. Missing data were imputed using multiple imputation.
Results
The mean incremental cost of the PATHS curriculum compared with usual practice was £32.01 per child, and mean incremental quality-adjusted life-years (QALYs) were positive (0.0019; 95% confidence interval [CI] 0.0009–0.0029). Assuming a willingness-to-pay threshold of £20,000 per QALY, the expected incremental net benefit of introducing the PATHS curriculum was £5.56 per child (95% CI − 14.68 to 25.81), and the probability of cost effectiveness was 84%. However, this probability fell to 0% when intervention costs included teacher’s salary costs.
Conclusion
The PATHS curriculum has the potential to be cost effective at standard UK willingness-to-pay thresholds. However, the sensitivity of the cost-effectiveness estimates to key assumptions means decision makers should seek further information before allocating scarce public resources.
