Minimizing attrition bias involves several strategies, including:
Retention Strategies: Implementing measures to keep participants engaged, such as regular follow-ups, reminders, and incentives. Flexible Study Design: Offering flexible participation options, such as online surveys or home visits, can reduce dropout rates. Data Imputation: Using statistical methods to account for missing data, such as multiple imputation, can help mitigate the impact of attrition. Sensitivity Analysis: Conducting sensitivity analyses to assess how different levels of attrition might affect the study results.
