Objective:
This study aimed to examine whether mothers' level of trauma exposure and posttraumatic stress disorder (PTSD) symptoms are related to their offspring's cognitive functioning.
Method:
Mothers exposed to the 1994 genocide perpetrated against the Tutsi (N = 181) and one of their adult offspring were recruited in Rwanda. Mothers and their offspring answered questionnaires on sociodemographic information, the level of trauma exposure, and PTSD symptoms. They also performed a backward digit span task and a similarity task to assess their working memory and abstract reasoning, respectively. Hierarchical regression models were used to analyze the data.
Results:
Mothers' level of trauma exposure, but not PTSD symptoms, was significantly related to their offspring's abstract reasoning performance after controlling for offspring's age, sex, and economic status. The relationship between mothers' level of trauma exposure, PTSD symptoms, and their offspring's working memory performance was not significant. Offspring's education was significantly linked to their working memory and abstract reasoning performance.
Conclusions:
The findings demonstrate that the intergenerational transmission of trauma can impact the cognitive functioning of the next generation. These results also illustrate the profound and long-term human impact of mass violence. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
