The present study investigated the role of cognitive control and positive memory characteristics with special attention to the mediating roles of cognitive process and cognitive fatigue in flood-stricken victims. A sample of 280 participants were selected from flood-stricken areas including Gonbad, Gomishan and Aghghala. Data were collected using PCL-5, CPOTS, MEQ_SF, Mental Fatigue Scale, WAIS-IV, Stroop Test and Wisconsin Card Sorting. The data were then analyzed using SPSS and Smart PLS-3 softwares. The findings indicated no direct link between cognitive process and PTSD symptoms. However, cognitive process played a full mediating role in the relationship between cognitive control and PTSD symptoms and a partial mediating role in the relationship between positive memory characteristics and PTSD symptoms. The findings also revealed cognitive fatigue played a partial mediating role in the relationship between both cognitive contol and PTSD symptoms and positive memory characteristics and PTSD symptoms. The findings further showed  the purposed model to investigate the relationships between the variables enjoyed a good fit. These findings can be the first step in identifying the PTSD symptoms of people who have been through flood trauma and can help us design evidence-based educational and rehabilitative programs to reduce psychocognitive pains of flood victims
