Modeling the Relationship Between Impairment of Executive Function on problem-solving strategies in major depressed patient: The mediating role of overgeneral autobiographical memory

The present study, with emphasis on CaR-FA-X Williams model, investigates the intermediate role of over-general autobiographical memory on the relationship between impairment executive functions with ineffective problem-solving in depressed people.
For this purpose, 56 subjects with major depression by sampling method during the period from April to September 2017 were selected . For data collection, after diagnosis of major depression by a psychologist, Autobiographical Memory Test, a problem-solving problem test and a Wisconsin card software were used. To analyze the research data using SPSS and IMOS software and path analysis method, structural equation modeling was used. The results showed that the direct effect of executive function on problem solving with a value of 0/283 is not significant at the level of 0/05. The indirect effect of executive function on problem solving with a value of 0/130 is significant at the level of 0/05. The total effect of the executive function on problem solving is 0/413, which is significant at the level of 0/05. Therefore, due to the insignificant direct and significant effects of indirect effect, oral memory is a general mediator variable in the effect between the executive function on problem solving.Therefore, the present study, confirmed by the Williams CaR-FA-X model, showed that depressed people, due to their negative mood, and impairment in executive functions, have a particular problem in restoring their memoirs, and this is a problem in retrieval, solving problems It also affects their problems and makes them produce less effective solutions. Therefore, more generative of autobiographcal memory as a mediating mechanism in the relationship between impairment in executive function and ineffective problem-solving in depressed people.
