COMMUNICATION PATTERN BETWEEN FEMALE BREADWINNERS AND THEIR CHILDREN
No full textThis study examines the communication pattern between female breadwinners and their children and the barriers in that communication process. This qualitative study was carried out among 12 female breadwinners from low-income families in Wedomartani Village, Ngemplak, Sleman, Special Region of Yogyakarta. It is drawn from the study that, first, there is good interpersonal communication between a female breadwinner and her children. It is clearly seen as all factors leading to an effective interpersonal communication are fulfilled, namely a) openness - the mother is actively creating a pleasant conversation so that her children will feel more comfortable in telling her everything that happens to them; b) empathy - the mother instills a sense of independence and respect for others in her children; and c) positive behaviors - the mother has a strong commitment to improve her family\u27s condition as shown in all her positive behaviors. Second, as the mother and her children can interchangeably be the communicator (sender) or the communicant (recipient) of information, this communication is categorized as direct (face-to-face), either one-way or two-way. Third, the barrier existing in the communication process between a female breadwinner and her children is mainly related to the mother\u27s limited time available to do her main duties as a mother, causing her housework to become abandoned. Another obstacle in this communication process is due to the children\u27s psychological condition that is affected by the lack or even the absence of father\u27s roles in their family, leading to an unstable emotion.
