About 10% to 12% of people with intellectual disabilities show self-injurious behavior (Hendrikse, 2017). Their caretakers are often strongly and emotionally involved with the clients who show these self-injurious behaviors. This study looks at the type of self-injurious behavior that occurs in care settings, the personality characteristics of the clients who show self-injurious behavior, how the supervisors interact with the clients who show self-injurious behavior and what level of support supervisors experience from the organization. This research was done using the data from the SCORE research project that was conducted earlier. This research shows that clients both bang their heads, scratch or pick their skin, and hit or bite themselves. In addition, the study finds that mental age and adaptive skills have a relationship with clients banging or biting themselves, adaptive skills and mobility problems have a relationship with head banging, and that the personal characteristics used in this research have no correlation with scratching or picking at their skin. In addition, clients who bang their heads often have additional funding for care and those who hit or bite themselves often have a higher ZZP indication. Finally, it appears that supervisors are generally satisfied with the way they respond to clients' needs, but that correctly assessing behavior and flexible responding to client needs is perceived more negatively when clients bang their heads or hit or bite themselves. Caretakers also experience more difficulties in working together concerning these clients. In contrast, clients who scratch themselves or pick their skin are perceived more positively. Caretakers are more aware of their needs and they receive more support from the organization.Show less
