Of all people who start the Combined Lifestyle Intervention (CLI), approximately 60% complete the full programme. This is the outcome of an in-depth study by RIVM. The CLI is a lifestyle programme that takes two years to complete. The dropout rate (27%) is slightly higher in the first year compared with in the second (20%). RIVM has concluded that the CLI would benefit from a more tailored approach to reduce the dropout rate.
The new report shows that the dropout rate has been decreasing over the years. Of all participants who started in 2019, half dropped out prematurely. This fell to 38% among participants who started in 2022. Additionally, the study has shown that most people (90%) actually start the CLI after an intake interview.
Reasons for dropping out
There are various reasons why participants do not fully complete the CLI programme. One that is often mentioned by participants is that the programme does not address their needs - for example, because it fails to provide new insights or practical tools. Another reason mentioned is that they did not click with the coach or group. Some participants drop out due to mental or physical issues.
Better information about the CLI
As part of this study, RIVM interviewed lifestyle coaches, GPs and participants, among others. They point out that it is important to explain even more clearly, during the intake, what the CLI involves. They also feel it is important for GPs to check whether people need other support before referring them to the CLI.
A more tailored approach
The interviewees also identified several points where the programme might be improved. One is a more tailored approach, with guidance tailored to a participant’s personal situation and preferences. Additionally, lifestyle coaches themselves would like to receive more effective training, especially in providing guidance to groups. RIVM’s advice is to find out, through further research, whether a more tailored approach within the CLI is feasible. A tailored approach could also entail higher costs. In addition, RIVM advises lifestyle coaches to more often share successful experiences and working methods with each other.
About the CLI
The CLI focuses on healthy nutrition and exercise. Additionally, it highlights issues that interfere with a healthy lifestyle, such as stress or sleeping problems. Healthcare insurers have covered the costs of participating in the CLI since 2019. RIVM monitors developments in the CLI on behalf of the Ministry of Health, Welfare and Sport. Earlier research has shown that, by the time they completed the programme, participants had lost 5% of their body weight, on average. Their quality of life also improved significantly.
