Abstract: The purpose of this study was to validate the Youth Problems Inventory (YPI). The sample for the study consisted of 150 students drawn from the part four faculty of Education of the university of Ado-Ekiti and part three students of the college of Education, lkere-Ekiti. The males numbered 85 while the female were 65. ne hundred and twelve were single while thirty eight were married. The ages range from 18 years to 32 years. The research instruments were the Youth Problems Inventory (YPI) and the Student Problem Inventory (SPI). The YPI, constructed by Okon in 1979, is designed for evaluation of students` problems. It was the main instrument. The SPI, constructed by Bakare in 1970, is a checklist meant to evaluate secondary school students` problems. It served as the validating instrument. To assess the reliability of the Youth Problems Inventory (YPI), test-retest reliability method was used with a time interval of two weeks. A reliability coefficient of 0.89 was obtained. Three hypotheses were generated for the study, testing sex, marital status and age groups. The result revealed that there no significant differences in the problems of male and female students, single and married students of different age groups. It was recommended that colleges and universities should try to find out students` problems (using problem inventories) as soon as they are admitted and assist them to get over the problems.
