- Depressed children show differing cognitive styles such as negative attributions and negative perception of self and the future. These cognitive styles may influence the onset and maintenance of a disorder.
- It is essential to understand the difference between cognitive deficiencies and cognitive distortions. 
- Cognitive deficiencies refer to a lack or insufficient cognitive activity in situations where cognitive activity is useful or beneficial to the child's adjustment (perspective-taking or problem solving).
- Cognitive distortions involve active cognitive processing but the thinking is "crooked." For example, these children would exaggerate a threat to their self or misperceive the demands of a particular environment. 
- Kendall et al. (1990) study found no evidence for deficiency in cognitive processing of depressed children. However, they found evidence that suggests depressed children experienced cognitive distortions which was observed through the children's unrealistic or poor self-evaluation. 
- Depression in youth is associated with social skills deficits
