Abstract
This study aims to identify how irritability affects middle school students¡¯ behavioral problems and whether behavioral activation system(BAS) or behavioral inhibition system(BIS) moderates the relationship between the irritability and behavioral problems. For this purpose, this study analyzed the data collected from 186 middle school students at age 12 to 15 (85 boys and 101 girls), and the results of analysis are as follows. First, the girls¡¯ irritability, BIS and internalizing problem were significantly higher than boys¡¯. Second, for both boys and girls, the internalizing problem was higher when the irritability and BIS was high. Also, as the level of the irritability, BAS, and BIS increased, the level of externalizing problem increased. Third, in the hierarchical regression analysis, the moderating effects of BAS was significant only for boys in the relationship between the irritability and internalizing problem. This finding suggests that the effect of irritability on the internalizing problem varies depending on the levels of BAS for boys. Fourth, the moderating effects of the BAS and BIS were not significant for boys nor girls in the relationship between the irritability and externalizing problem. However, for both boys and girls, only the direct effect of the irritability, BAS and BIS were significant for externalizing problem. Finally, based on the findings, the theoretical and clinical implications as well as the limitations of the study were discussed.
