Recently, students with pervasive developmental disorder (PDD) increase in campus mental health. And we need to help them especially with mental symptoms. We investigated changes of symptoms, time of changes, patterns of personal relationships, and attachment in their infancy of students with PDD and discussed about factors of vulnerability and resilience. Factors of vulnerability were adolescent problem and life events such as admission into university and laboratories. Factors of resilience were attachment for their mother and experience in being helped.

These results indicate that it is important to make intervention at admission into university or laboratories, and that when we treat students with PDD, it is necessary to get information about attachment in their infancy and make an assessment of patterns about personal relationships.
