Abstract
In severe mental illness (SMI), such as schizophrenia, rehabilitation begins immediately. Aside from the token economy, there is limited literature on behavioral modification (BM), which is a crucial aspect of rehabilitation for person with severe mental illness (SMI). We demonstrate the implementation and effectiveness of BM for one year in managing behavioral difficulties in a person with SMI. The direct observation method and the ABC functional analysis model were used for evaluation. Management, such as reinforcement and punishment, was implemented. Pre- and postassessments revealed a considerable decrease in problematic behaviors. This article also highlights the obstacles faced while managing the case and caregiver burden in rehabilitation. In persons with SMI, the application of BM enhances the patient's functionality and reduces the caregiver burden.
