Rehabilitation has become a crucial component of modern correctional systems. With rising concerns about recidivism, overcrowding, and the mental health of Persons Deprived of Liberty (PDLs), it is essential to evaluate how effective rehabilitation programs like the Therapeutic Community Modality Program (TCMP) are in promoting behavioral change and reintegration into society. Understanding its implementation and impact provides valuable insights for improving strategies, resource allocation, and policy-making. This study examined the implementation and perceived effectiveness of the TCMP within Tacloban City Jail. In a carceral environment strained by congestion, limited resources, and structural vulnerabilities, the study recognized the urgent need for approaches that restore rather than merely detain. Grounded in social learning, rehabilitation, and organizational theory, this investigation explored how the TCMP fostered behavioral transformation and emotional healing among PDLs. Using a mixed-method approach, data were gathered through validated instruments and qualitative inquiries. Jail officers and PDLs provided meaningful insights into the program’s structure, challenges, and impact. The findings are both encouraging and sobering. The TCMP nurtured prosocial behaviors, accountability, and a sense of community, yet issues such as limited post-release support and inconsistent delivery remain. Ultimately, this study offers a human story of change, hope, and resilience, advancing restorative justice in correctional rehabilitation.
