This module provides an introduction to the process of communication and explains the concepts of effective communication, art of listening and open-ended questions. The module discusses one-way and two-way communication. It also describes the communication cycle and its components including sender, receiver, message, medium and feedback. Effective communication is an important part of behaviour change communication. It helps in winning people’s trust and is useful in discussing even personal and sensitive issues. Similarly active listening also helps in behaviour change. Active listening helps in knowing a person and gathering vital information about him/her and his/her family and community. It further facilitates identification and understanding of a person’s needs, problems and potential challenges to behaviour change. While listening to the person, it is also important to ask questions to gather relevant information about him/her. Asking questions is also an art.
