Naikan is a contemplative self-observation practice that originated from Japanese Shin Buddhism and is utilized for rehabilitating prison inmates in many countries. Although some investigations have provided initial evidence for its efficiency in decreasing recidivism, there is still a need for further investigation of the effectiveness of Naikan on other outcomes through more controlled studies. The present study aimed to investigate the efficacy of Naikan therapy on male offenders' perceived social support and externalized blame. Ninety-two male offenders were randomly assigned to either the experimental group or to the waiting group. All participants were evaluated by the Multidimensional Scale of Perceived Social Support and the Externalization subscale of the Test of Self-Conscious Affect before and after Naikan therapy. The results suggested that participants who received Naikan therapy showed higher levels of perceived social support and lower levels of externalized blame after Naikan therapy than before.
