Final answer:
Lack of immediate social support does not strongly predict the development of posttraumatic stress disorder (PTSD).
Step-by-step explanation:
A meta-analysis conducted by Ozer, Best, Lipsey, and Weiss (2003) found that lack of immediate social support does not strongly predict the development of posttraumatic stress disorder (PTSD). While factors such as greater trauma severity and experiencing trauma in isolation were found to be predictive of PTSD, the absence of immediate social support was not strongly associated with the development of the disorder. It is important to note that the presence of social support can have a positive impact on the recovery process for individuals with PTSD.
