There have been numerous cases of behavior problems among Kenyan secondary students. The study investigated the relationship between personality subtypes and indulgence in behaviour problems among students in selected Kenyan secondary schools. A Correlation Survey Design was adopted. The target population was 11479 form three students drawn from three sub counties in Kenya. The Eysenck personality and indulgence in behavioral problems questionnaires were used to collect data for the study. One-way Analysis of Variance was used to analyze the data with aid of SPSS. The findings indicated that there was a statistically significant difference (at the p<.05 level) in students’ indulgence in behaviour problems scores for the three personality subtypes [F (2, 344) = 1181.25, p<.05]. The study recommends that teacher counselors should teach Self-Regulation skills to extroverted students. The study recommends that the teacher counselors should identify at least student’s personality assessment.
