Experimental groups received cognitive-behavioral interventions and sensory processing styles training orderly. Control group received no training. A child behavioral questionnaire was used to collect information. After scoring the questionnaire and extracting the data, SPSS-21 software used for statistical analysis of multivariate covariance and independent t test. Results: The findings showed that cognitive-behavioral interventions and the training of sensory processing styles have a significant effect on behavioral problems in children and have reduced the internalization and extraversion problems in experimental groups and the effectiveness of the cognitive-behavioral intervention in reducing behavioral problems in children is more significant than teaching sensory processing styles.
