Özet:

Almost every individual in lifetime has the possibility of experiencing traumatic events which may highly impede coping mechanisms. Many studies indicated the prevalence of Post Traumatic Stress Disorder (PTSD) which is one of psychiatric consequences of traumatic events (TEs), as ranging from 1% to 9%. In recent years, attention to positive changes/transformations following TEs has gained interest. Post Traumatic Growth (PTG) is the concept that taps these transformations. The aim of the present study, is to examine prevalence rates of TEs, probable PTSD in a community sample, and to analyze ways of coping, perceived social support, event-related rumination as possible predictors of posttraumatic stress (PTS) symptom severity and PTG. The role of personality and reported event-severity on two outcome variables i.e., symptom severity and PTG were also analyzed through structural equation modeling to test direct and indirect effects. The sample consisted of 740 adults, 67.3% of them reported experiencing at least one TE, and prevalence of probable PTSD found as 10.8%. The main findings indicated that neuroticism, experiencing intentional/assaultive violence event-types, intrusive/deliberate rumination, fatalistic coping were associated with higher symptom severity, whereas conscientiousness, injury/shocking event-types, deliberate rumination, problem-solving coping, seeking-support coping, perceived social support predicted higher PTG. The results of model-testing, indicated direct and indirect effects through personality to symptom severity and PTG, where the paths showed the mediator roles of rumination and coping. The results were discussed via theoretical models, and provided information that can aid in the delineation of risk-groups following TEs, and contributed to mental health services.
