**3.3. Phase 5: Development**

During the formative research, the main ideas for intervention are determined, and primary materials develop. Before completing the production of messages and materials for implementation, it is required to pretest the key elements including methods, communications, and strategies. They are presented to some members of the target audience and receive their feedback. Modifications are made based on the feedback. Typical methods for pretesting include focus groups, interviews, and surveys.
