The methods, research, and theory behind OnePlusOne’s approach to relationship support.
OnePlusOne methodology
It is never too late to learn the skills that help you build happier, healthier relationships.
At OnePlusOne, we create evidence-based resources that support people to develop relationship skills they can use throughout their lives. Our research and evaluation contributes to the wider evidence base on how relationships work and how they affect individuals, families, and wider society.
To develop these innovative resources, we draw on evidence from a wide range of disciplines. Our inclusive co-design process involves the people who use our tools, including parents and practitioners from communities across the country.
Below are the core disciplines that underpin our work.
Evidence foundation
Relationship science aims to understand how relationships form and develop, how they are maintained, and why they break down. It draws on methods from psychology, sociology, and economics to answer four key questions:
Before designing any resource, we review existing evidence from relationship science. This ensures that all of our projects are grounded in knowledge of what works, creating a link from theory to practice.
From theory to practice
Behaviour change theories help us identify and understand why people behave the way they do. When we understand the drivers behind behaviour, we can design interventions that support people to change it.
These theories include:
These theories describes how our resources, intentions, and environment can influence the way we behave. For example, social learning theory suggests that people learn by observing others, and that confidence in one’s own ability plays a vital role in making change possible.
Applied method
Behaviour Modelling Training (BMT) is one of the behaviour change methods we use in our digital tools. This applies the principles of Bandura’s social learning theory, recognising that when people believe they can change a behaviour, they are more likely to try it and maintain it.
BMT works by:
BMT has been shown to strengthen attitudes, increase intention to change, and build confidence in the possibility of behaviour change.
Our framework
OnePlusOne has developed the relational capability framework throughout its history. This unique framework draws on the capability approach created by economist Amartya Sen, which was expanded by philosopher Martha Nussbaum. The approach suggests that societies should promote the capabilities people need to live a life they value. The ability to form meaningful relationships is one such capability.
Relational capability begins in infancy. Early childhood is when we develop emotional understanding, perspective-taking, and emotional regulation. These shape our internal relational capability.
With these foundations, children form their first relationships with the people closest to them. Over time, these capabilities grow and support them to build connections at school, at work, and throughout adult life. Relational capability is an essential part of what makes us all human.
Describing a specific set of skills or behaviours.
Providing a visual demonstration.
Offering opportunities to practise.
Supporting learners through feedback and social reinforcement.
“OnePlusOne’s vision is: Relational capability for all. We envisage a world where everyone has the resources to develop their relational capability. Whatever relationships you have, we want you to be able to do them well.
We’re always happy to discuss how our tools are developed and how they might support your project.
