This paper will assess the efficacy of an integrated, person-centered stepped care model in persons with intellectual disability in forensic contexts based on rehabilitation and quality of life measures. The model integrates systematic therapeutic interventions, such as Cognitive Behavioral Therapy (CBT), Occupational Therapy (OT), and Speech and Language Therapy (SLT) in the overall care delivery model. In order to examine it, a sample of five subjects was evaluated on indicators like Functional Independence, Behavioral Stability and Quality of Life (measured on indicators like Autonomy, Psychological Wellbeing, and Social Inclusion) pre-intervention and post-intervention. Findings demonstrate great improvements: Functional Independence seemed to be improved by 22, Behavioral Stability by 25, and the Quality-of-Life indicators was improved on average by 30% to 33. Although these are good results, the research has limitations such as limited sample and duration of intervention. The future studies need to utilize bigger and more diverse samples and longer follow-up to determine the long-term impacts. Moreover, technology-assisted intervention integration might be considered in order to improve the service delivery in the forensic context. The results indicate that the person-centered stepped care model provides a holistic approach to enhancing the rehabilitation progress and quality life in forensic intellectual disability services.
