Trajectories of PTS, Depression After Civil Unrest

Am J Community Psychol; ePub 2018 Sep 17; Galovski, et al

Women were more at risk for depressive symptoms, but not posttraumatic stress (PTS), according to a recent study that examined trajectories of PTS and depressive symptoms secondary to exposure to violence during civil unrest in citizens (n=311) and law enforcement (n=255) over 1.5 years following exposure to civil unrest in Ferguson, MO. Latent class growth modeling was used to examine trajectories of PTS and depressive symptoms. Researchers found:

  • 4‐class quadratic solutions for both PTS and depressive symptoms demonstrated best fit.
  • Similar patterns emerged for such that most participants were classified as resistant (57% and 67%, respectively), followed by resilience (23.8% and 17.2%), chronic (12.6% and 12.0%), and worsening (6.1% and 4.4%).
  • When all predictors were entered in a single model, race, and membership in citizen or law enforcement groups did not distinguish trajectories of recovery.
  • Higher income and social support emerged as consistent protective factors against PTS and depressive symptoms, while trauma history emerged as a risk factor for PTS.
  • Women were more at risk for depressive symptoms only.
