The role of specific sources of social support on postinjury psychological symptoms

The role of perceived social support from specific sources (e.g., families, friends, and significant others) on the development of postinjury posttraumatic stress disorder (PTSD) and associated psychological symptoms (e.g., depression and anxiety) remains relatively unexplored. We examined the predictive role of social support from specific sources on psychological symptoms among emergency department (ED) patients following motor vehicle crash (MVC). Research Methods/Design: Sixty-three injured patients (63.5% female; 37 years old on average) with moderately painful complaints were recruited in the EDs of two Level-1 trauma centers within 24 hr post-MVC. In the ED, participants completed surveys of baseline psychological symptoms and perceived social support; follow-up surveys were completed at 90 days postinjury.

Most of the sample (84.1%) was discharged home from the ED with predominantly mild injuries and did not require hospitalization. After adjusting for race, sex, age, and baseline symptoms, hierarchical regression analyses demonstrated that lower perceived social support in the ED predicted higher PTSD symptoms and depressive symptoms (but not anxiety) at 90 days. This effect seemed to be specific to significant others and friends but not family.

MVC-related injuries are robust contributors to psychological sequelae. These findings extend prior work by highlighting that perceived social support, particularly from significant others and friends, provides unique information regarding the development of psychological symptoms following predominantly mild MVC-related injuries. This data may serve to inform recovery expectations. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
