Cognitive distortions are an important area of investigation in terms of problematic behaviors. Although relationship between dysfunctional beliefs and behavioral problems is well established, the strength of relationship especially towards externalizing internalizing behavioral problems is not known. Therefore, the purpose of present book was to examine the role of cognitive distortions in the development of behavioral problems (internalizing and externalizing behavioral problems). In addition to cognitive distortions, the predictive role of certain demographic variables (such as gender, socioeconomic status and family system) and self-esteem was also examined.
