Wellbeing Science and Intervention Design

Most corporate wellbeing programmes fail because they are designed for the average employee who does not exist. They deploy population-level interventions — mindfulness apps, resilience workshops, gratitude journals — based on research showing small-to-medium effects across aggregate samples. But the aggregate conceals the individual. What works for one person does not work for another.

About This ServiceWellbeing Science and Intervention Design

This service applies precision wellbeing science to intervention design. I begin with a construct audit: clarifying what your organisation actually means by ‘wellbeing,’ identifying the gap between that definition and what your measurement instruments capture, and establishing a validated measurement framework grounded in contemporary theory — PERMA, self-determination theory, and person-environment fit models. From there, I design population segmentation strategies using psycho-behavioural cluster analysis.

The output is an intervention architecture with evidence-mapped logic models, precision targeting frameworks, and an outcome measurement plan that can distinguish signal from noise. Every recommendation is grounded in peer-reviewed evidence and labelled by evidence quality.
