A Study Evaluating Mindfulness and Naikan-Based Therapy: AEON-HO for Attachment Style, Self-Actualization, and Depression

AEON-HO (Altering emotional organization-holistic operation) contains methods of Naikan therapy and mindfulness. Naikan and mindfulness are originally from Buddhism tradition, and they have a high affinity. AEON-HO was conceptualized to improve attachment issues and the growth of self-actualization, because Naikan and mindfulness are known to be effective for attachment issues but partially if they are used independently. Naikan can approach to attachment avoidance, while mindfulness can approach to attachment anxiety. The primary purpose of this study was to assess the effectiveness of AEON-HO on attachment styles, self-actualization, and depression by using “attachment style scale the Experiences in Close Relationships inventory–the generalized–other–version (ECR-GO),” “self-actualization scale” translated to Japanese, and “center for epidemiologic studies for depression scale.” Participants have taken these three psychological questionnaires before and after the eight-week program of AEON-HO, and the results of scales were compared. Participants were 36 adults with a mean age of 49 years (SD = 3.9). Changes in two attachment styles, anxiety and avoidance and depressive state, were observed between pre- and posttest, while there were no significant changes in self-actualization. However, attachment anxiety and self-actualization were correlated negatively in pre- and posttest, while attachment avoidance and self-actualization were correlated negatively only in pretest.
