Abstract Objective: To compare three different groups of children with disruptive behavioral problems to a control group, on one module of the DB-DOS, a new observational method for assessing preschool disruptive behavior. The DB-DOS assesses observed disruptive behavior in three domains, problems in Anger Modulation, Behavioral Regulation and Competence across one context, Examiner Engaged. Method: A total of 114 coded DB-DOS sessions formed the sample. Four groups have been composed based on their diagnosis; a group of children with ODD or CD (called DBD), a group with DBD + ADHD, a group with ADHD and a control group. Group differences were tested using analyses of variance and post hoc tests. Results: There was an effect of group on all domains. Post hoc analyses revealed that the DBD + ADHD group scored significantly higher on both problem behavior domains than the control group. Further, the DBD group scored significantly lower on the competence domain than the control group. Conclusions: According to expectation the DBD + ADHD group showed more behavioral problems than the control group. However, the DBD group did not. Besides, according to expectation the DBD group scored lower on competence. We conclude that these results partially support the clinical validity of the DB-DOS. We expect that the clinical validity will increase when data on the other two contexts of the DB-DOS will be added.
