1. Compliance and Adherence: If an intervention is not acceptable to the target population, they are less likely to comply with it, reducing its effectiveness. 2. Data Quality: In epidemiological studies, high acceptability can lead to better participation rates, thereby improving the quality and reliability of the collected data. 3. Sustainability: Acceptable interventions are more likely to be sustainable over the long term, as they are more likely to receive continuous support from the community and stakeholders.
