This study used parent training (PT) for parents of children with Developmental Disorder. The usefulness of PT was evaluated parent's general health questionnaire (GHQ30 Japanese version) and the number of tasks achieved by the parents at their home setting. Total participants were 141 parents during five years. Each children were diagnosed as autism, asperger syndrome, ADHD or mental retardation. The five training components of the program were: lectures about behavior analytic theory, role playing, group discussion, homework and recording of behaviors about tasks, and feedback to parents from the training staff based on their recordkeeping. We carried out a lecture of applied behavior analysis in the first half of the each session and carried out group work in the latter half. The average scores of GHQ30 were improved. The change was significant. Regarding the behavioral modification of the children, 42.6-64.9% task achievement rate was obtained. The recent increase in the numbers of NEET young people (not in education, employment or training) is socially anxious problem in the many countries of the world. The purpose of the present study was to investigate the relationship between career indecision and the factors of ego identity. 4 types of mental situations (confusion, anxiety, hesitation and prudence) were constructed by the career indecision scales and 5 factors of adolescent sub-identity(group identity, individual identity, sex role identity, occupational identity and social identity) were constructed by the identity scales A questionnaire was administered to 408 university students, 182 males and 226 females in Japan. The findings by using multiple regression analysis showed that the total of career indecision were greatly influenced by the achievement of total ego identity (R square,.51). The confusion type of career indecision was closer relationship with the individual identity(β,−.352 p<.01). The anxiety types of career indecision was related to sex role identity (β,−.312 p<.01). The scales of occupational identity showed high relationship with total scores of the career indecision(β, −.402 p<.01) in male students, although the relationship between the occupational identity and the career indecision in female students was low(β,−.214 p<.01).
