This study targeted a model group of the parents of children in Hikikomori state (the individual) recruited in A prefecture. The purpose is to practice a family support program aiming to enable such parents to respond to the individual in an understanding manner in order to explore the effectiveness of the program and create a rubric that will serve as the evaluation criteria. Thirteen parents (six males and seven females) participated in the family classes, which were conducted six times. The results of the rubric evaluation established the effectiveness of the program with likely influences of the following three factors. (1) The focus on mutual exchange and narration of experiences through dialogue between members, which is a central element of the self-help group, was effective. (2) The use of the rubric allowed elaborating on the complex qualitative changes in each participant, further enhancing the inter-subjectivity of evaluators and avoiding the risk of erroneous judgments. (3) One factor that may not lead to an understanding response of parents is that they have difficulty communicating with their children.
