What strategy might one employ to mitigate the possibility of having an excessive attrition rate for research subjects?

This means that the participant of the experiment group are frequently leaving the experiment before outcomes are made. Therefore there is incomplete ascertainment of the primary outcome. Strategy to mitigate this involves retention strategies. This is through regular communication by encouraging the participants to remain in the experiment. This means using emails, phone calls to frequently appreciate the participants.

Effective communication is necessary to eradicate any misunderstandings. Regular communication ensures that the participants stay in the experiment. This means that the outcome will remain objective as the experiment will be completed. The participants need to feel a sense of belonging and value in order to remain participants in the experiment. The follow-up procedures ought to be timely and much more frequent to prevent losing the participants. This method in return motivates the participants to be part of the experiment due to the constant assurance. Therefore, systematic reviews will be required in order to evaluate the retention strategies to measure its effectiveness. It is for this reasons that incentives can be applied in order to motivate the participants to remain in the experiment.
