Behavioral Intentions and Change Interventions
Summary
Behavioural intentions lie at the heart of many theories of human action, representing an individual’s plan or commitment to perform a given behaviour. The most influential framework, the Theory of Planned Behaviour, posits that intentions arise from attitudes towards the behaviour, perceived social pressures (subjective norms) and perceived behavioural control, which reflects confidence in one’s ability to act. Despite strong intentions, a consistent intention–behaviour gap is often observed, highlighting the importance of intervention strategies that bridge intention and action. Change interventions range from educational programmes and persuasive communication to more subtle ‘nudge’ techniques and digital tools that provide real-time feedback or prompt action at critical moments. Such interventions may target one or more antecedents of intention—shaping attitudes through information, aligning subjective norms via social modelling, and bolstering perceived control by building skills or removing barriers. Across health, environmental and organisational domains, theory-based interventions have demonstrated that combining planning prompts, self-monitoring and social support can convert intentions into sustained behaviour change. Ongoing work emphasises tailoring interventions to context, harnessing digital platforms for personalised delivery, and integrating behavioural economics insights to design scalable, cost-effective programmes with measurable impact on public health, sustainability and well-being.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
