The purpose of this paper is to investigate the validity of the developmental screeningmethod which was originally devised by the author. The subjects were 11 young adults aged 23 -25 years old (1971-73 birth cohorts) and their parents, 19 in number, who answered thequestionnaire of developmental problems in the early adulthood; a semi-structured interviewmethod by means of telephone or home visit was conducted. There were two major findings. First, the validity rate was 89.5%, while the false negativerate was 0%. Second, three subjects were identified as the targets of primary prevention and intervention, and the questionnaire survey by telephone or home visit revealed that all of themhad developmental problems. It is thus concluded that this screening method is valid .
