This study underscores the significance of assessing the capabilities of rehabilitation officers in navigating challenges, devising innovative work methods, and successfully executing the rehabilitation process. This is particularly crucial amid the dual challenges of overcapacity and the repercussions of the Covid-19 pandemic, making it an essential area for research. To be specific, it aims to obtain empirical evidence about the influence of proactive personality and supportive supervision on proactive work behavior, as well as the mediating role of Role Breadth Self-efficacy and Change Orientation. This research was conducted on all rehabilitation officers at the Narcotics Penitentiary in Sumatra, totaling 272 respondents. This study employs a quantitative method via a questionnaire using a purposive sampling technique. The data was subsequently examined using the Lisrel 8.70 software and Structural Equation Modeling (SEM). It can be concluded from the results that the rehabilitation officers for narcotics addicts at the Narcotics Penitentiary can create and improve proactive work behavior properly through the influence of proactive personality, supportive supervision, role breadth self-efficacy, and change orientation. The study may suggest new ways of working and generate new ideas to increase initiative, encourage feedback, and voice employee concerns. Furthermore, this research has the potential to pinpoint deficiencies in proactive work behavior, serving as a foundation for designing interventions or training programs. These initiatives aim to enhance the innovative and creative contributions of rehabilitation officers in the rehabilitation process.本研究凸显了评估戒毒康复专员应对挑战、创新工作方法并顺利推进康复流程的能力的重要性。在收容过载与新冠疫情后续影响的双重挑战背景下，这一议题的研究尤为关键，因此成为极具价值的研究领域。具体而言，本研究旨在获取关于主动性人格与支持性督导对主动性工作行为的影响，以及角色广度自我效能感（Role Breadth Self-efficacy）与变革取向（Change Orientation）中介作用的实证证据。本研究以苏门答腊禁毒监狱的全体戒毒康复专员为研究对象，共计272名受访者。研究采用定量研究方法，通过目的性抽样技术编制问卷开展调研，后续借助Lisrel 8.70软件与结构方程模型（Structural Equation Modeling，SEM）对数据进行分析。研究结果表明，该禁毒监狱的戒毒康复专员可通过主动性人格、支持性督导、角色广度自我效能感与变革取向的共同作用，合理塑造并优化自身的主动性工作行为。本研究可为提升员工主动性、鼓励反馈及表达员工关切提供全新工作思路与创新理念。此外，本研究还有助于识别主动性工作行为存在的不足，为设计干预方案或培训项目奠定基础，旨在提升戒毒康复专员在康复流程中的创新性与创造性贡献。
