With this study, it was aimed to determine the problems experienced by children with autism during dressing/dressing, and to provide mothers with the ability to apply clothing modification techniques to eliminate these problems. The universe of the research is the mothers of children with autism living in Turkey, and the purposeful sample is the children with autism between the ages of 6 and 12 residing in Istanbul, who are educated in the Tohum Autism Foundation, OÇEMs, MEB-affiliated special education classes, Special Education and Rehabilitation Centers. The study consisted of 10 mothers who voluntarily agreed to participate in the study. A guide (GİMUK) has been prepared for mothers, explaining the photographic and step-by-step clothing modification techniques that will facilitate the dressing of their children with autism. Due to the design and implementation of the guide, a "design-based research model" was used. The needs of each child were individually assessed, based on data collected through an online parent survey. For this reason, Tim Brown's "Innovative Field Approach" and "User-Centered Design" models were preferred. First, it was determined which techniques would be applied to which clothing group with an online survey. Then, the prepared GİMUK was converted into an e-guide and presented to mothers for review. With the online survey, it was measured whether the applications in GİMUK contributed to children and mothers with autism. The mothers who answered the questionnaire stated that GİMUK would contribute to the solution of dressing problems of children with autism. As a result, it was thought that printing and duplicating GİMUK, including different clothing groups, would be accessible to all mothers with autistic children and could be applied by more people.
