Function in patients with posttraumatic stress disorder (PTSD) in Declarative memory: controlling role of metacognition

The objective of the current research is to compare the function of declarative memory among war veterans who are suffering from PTSD, war veterans who are not suffering from PTSD and normal people without any war experience; the research has also aimed at studying and comparing the influence of the modifying role of meta cognition on the function of declarative memory among the three groups of the study.60 people have been selected and placed in three groups: 20 war veterans suffering from PTSD, chosen by PTSD scales; 20 veterans not suffering from PTSD and 20 normal people without any war experience. All three groups were evaluated by WatsonPTSD questionnaires, declarative memory memory interview and delayed recall story) and meta cognition questionnaire. The research hypotheses were tested by multivariate analysis of covariance (MANCOVA). The result have indicated that the function of declarative memory in the three groups without the control of meta cognition moderator is significant, in another word the declarative memory function in war veterans suffering from PTSD is different with the two other groups. It can be also deduced from the results of the research that the declarative memory function by the control of meta cognition modifying role was not significant this time which indicates the modifying role of meta cognition in decreasing the declarative memory function in war veterans suffering from PTSD in comparison with the two other mentioned groups.
