The mutual influence of parent-child maladaptive emotion regulation on posttraumatic stress following flood exposure.

Decades of disaster research support the influence parents have on their children's adaptation. Recently, research has shifted to focus on disasters as a whole family experience. Using the actor-partner interdependence model, this study examines maladaptive cognitive emotion regulation strategies in parents and children and how these strategies influence their own and one another's posttraumatic stress symptoms (PTSS). The present study includes 485 parent-child dyads who experienced the 2015-2016 Texas floods. The majority of parents identified as mothers (66.3%), with a male child (52.8%) whose average age was 13.75 years. Mplus was used to identify the models and evaluate differences between each cognitive emotion regulation strategy across parent-child dyads in the high disaster exposure group compared to all other levels of exposure (other-exposure). Odds ratios examined differences not captured by the actor-partner interdependence model. Support for interdependence was found for the other-exposure group, suggesting parents and children mutually influence each other's PTSS by their own cognitive emotion regulation. No interdependence was found in the high-exposure group. However, high-exposure child actor effects were found for self-blame and other-blame, and child partner effects were only found for self-blame. Parent actor effects were only significant for catastrophizing and parent partner effects for catastrophizing and rumination. Odds ratios for the high-exposure group found that only child self-blame influenced parent PTSS, and only parent rumination and catastrophizing influenced child PTSS. Implications for supporting families after disasters are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
