The present research aims to compare the cognitive performance of the adolescents suffering from MDD and PTSD in the working memory and information processing. the selected sample in this casual-comparative study included 15 MDD patients, 15 youth PTSD subjects and 15 normal subjects who were matched by age, IQ, sex as well as social and economic status variables. The tool package employed in this investigation comprised child depression inventory (CDI), State-Trait Anxiety Inventory, Impact of Event Scale (IES-R), Wechsler’s Memory and Intelligence Test, and The Information Processing Index Test. Findings were analyzed using the ANOVA, MANOVA analysis statistical method.as indicated by our result, in the verbal memory there is a significant difference between groups of depression and PTSD and between depressed and normal subjects. in the reverse spatial working memory there are significant differences between normal and PTSD. in the visual memory and information processing, the significant difference is between normal and both PTSD and depressed.The findings of this study confirm the disorders of working memory and speed of information processing in adolescents with depression and post-traumatic stress disorder. 

The purpose of this study was to investigate the mechanism of the effect of behavioral activation therapy (BA) through cognitive flexibility and emotional flexibility on the symptoms of women with major depressive disorder. This study was based on the single-subject design. The research sample consisted of five women with major depressive disorder (BDI-II), Beck Anxiety (BAI), Cognitive Flexibility (CFI) and Emotional Flexibility (EFI) at baseline and during the stage of depression. Treatment was evaluated. To analyze the data, trend, slope, and charts were used to determine the clinical significance of the percentage of recovery, percent reduction, effect size and Cohen index. The findings indicated that behavioral activation therapy significantly contributed to enhancing the cognitive flexibility and emotional flexibility of patients with major depressive disorder. In general, the results of the research indicated that the benefits of behavioral activation treatment as an effective intervention were used to increase the cognitive flexibility and emotional flexibility of women with major depressive disorder.
