This project presents the effectiveness of Intensive Personality Education (IPE) on the incarcerated individuals’ interpersonal behavior along with the effect in reduction of recidivism. This thesis then explains the positive reformation on the livelihoods of prisoners. The performance analyses were generated based on the two year contents of the observational analyses and proposes the desirable direction on this education program with the goal of policy making This research conducted the comparative analysis on 9,973 inmates that have participated in the IPE program. After evaluating the assessment, an accurate change in the indexes of 1) law-abiding attitude, 2) family relation, 3) self-control, and the 4)pro-sociality, 5)interpersonal relation were all detected; more importantly, a statistical output was identified in the indexes of 1) law-abiding attitude, 2) family relation, 3) pro-sociality, 4)interpersonal relation. Additionally, there was a distinction on the rate of re-incarceration between the individuals that received the IPE education and the individuals that did not (3.71% in 2015 and 0.31% in 2016). Moreover, the inmates that received IPE program had 2.62% lower rate in the punishment rate that affected a significant amount of the livelihood on the prisoners. These outputs help conclude that this program promotes successful rehabilitation of the ex-offenders. As a foundation of this report, three proposals for the development of the IPE program and the successful reintegration to the society of inmates are as follow: First, additional provision on the specialized manpower and constructing building related infrastructure are critical. Secondly, providing standardized education plan in order to reduce the difference in educational quality by region and implementing small-scale education training need to be practiced to increase the effectiveness of this program. In order to encourage the participants’ operant participation, providing incentive as a grant as well as educational period fixation are also necessary. Finally, based on different types of crime, the incarcerated individuals must receive psychological therapy that will anticipate the positive change on each individual’s personality.
