STRATEGI KOPING IBU DALAM MENDAMPINGIANAK PENDERITA KANKER DI YAYASAN KASIHANAK KANKER INDONESIA (YKAKI) JOGJAKARTA SLEMAN, D.I YOGYAKARTANIM.: 22102050105Alchanna NadhifahauthorA diagnosis of childhood cancer not only affects the child's physical condition but also has significant psychological, social, and economic impacts on mothers as the primary caregivers throughout the treatment process. These various challenges require mothers to adapt by employing effective coping strategies in order to fulfill their caregiving roles. This study aimed to identify the coping strategies used by mothers in caring for children with cancer at the Indonesian Childhood Cancer Foundation (Yayasan Kasih Anak Kanker Indonesia YKAKI), Yogyakarta Branch. This research employed a descriptive qualitative method using a case study approach. Data were collected through observation, in-depth interviews, and documentation. The data were analyzed using the stages of data collection, data reduction, data display, and conclusion drawing. The findings revealed that mothers experienced various challenges while accompanying their children during cancer treatment, including psychological distress caused by the initial diagnosis and uncertainty regarding the child's condition, difficulties throughout the treatment process, financial burdens, and changes in social and family life. To cope with these challenges, mothers employed two major forms of coping strategies proposed by Lazarus and Folkman: problem-focused coping, consisting of confrontative coping, planful problem solving, and seeking social support; and emotion-focused coping, consisting of self-control, distancing, positive reappraisal, accepting responsibility, and escape-avoidance. Among these strategies, positive reappraisal, seeking social support, and accepting responsibility were the most frequently used. The findings also indicated that the use of coping strategies varied among participants depending on the complexity of the problems encountered, the child's health condition, the availability of social support, and the resources available to each mother. Overall, these coping strategies enabled mothers to adapt to various challenges and maintain their roles as primary caregivers throughout their children's cancer treatment.
