Prevalence rates of traumatic events, probable PTSD and predictors of posttraumatic stress and growth in a community sample from İzmir

Gül, Ervin
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.


Pain perception, distress tolerance and self-compassion in Turkish young adults with and without a history of non-suicidal self-injury
Tuna, Ezgi; Gençöz, Tülin (Springer Science and Business Media LLC, 2020-02-01)
Individuals with a history of non-suicidal self-injury (NSSI) tend to have altered pain perception and difficulty in regulating their emotions. Previous work on NSSI has relied heavily on retrospective self-report data and clinical Western samples. The present study explored pain perception, emotional reactivity, distress tolerance and self-compassion in a sample of non-clinical Turkish young adults with and without a history of self-injury by employing a multi-method, laboratory-based design. Participants ...
The predictors of the traumatic effect of extramarital infidelity on married women: coping strategies, resources, and forgiveness
Özgün, Serkan; Fışıloğlu, Hürol; Department of Psychology (2010)
The aims of the present study are to examine the traumatic effects of EMI on the offended partners as well as to find out the predictors (coping, resources, and forgiveness) of the severity of PTSD. The participants of the study consisted of 189 married women who had continued their marriage after discovery of partners’ EMI. EMI was assessed with one item measure with the six-point continuum starting from “entirely sexual” to “entirely emotional” involvement. The instruments of the study: Post-Traumatic Str...
The association of self-discrepancy with depression and anxiety: Moderator roles of emotion regulation and resilience
Gürcan Yıldırım, Derya; Gençöz, Tülin (Springer Science and Business Media LLC, 2020-03-23)
Self-discrepancy theory posits that people experience emotional vulnerabilities to specific emotions when they have discrepancies between their actual, ideal and ought selves. The purpose of the current study was to test the effect of self-discrepancies (discrepancies between actual self and ideal, ought, and undesired selves) on depression and anxiety in a Turkish population, and to examine the moderator roles of emotion regulation and resilience in the relationship between self-discrepancies and negative ...

Aksoz-Efe, Idil; Erdur Baker, Özgür; Servaty-Seib, Heather (Informa UK Limited, 2018-01-01)
Grief following a death loss is a common experience that all individuals face at some point in life. There, however, are only a few in-depth studies regarding grief in cultures around the world and specific roles that rituals and beliefs related to death may have in the grieving process. Results of interview data from eight grieving Turkish women revealed three themes: (a) metaphors of loss, (b) funeral rituals, and (c) rituals in relation to control and personal factors. Overall, participants' sense of con...
Vulnerability Factors in OCD Symptoms: Cross-Cultural Comparisons between Turkish and Canadian Samples
Yorulmaz, Orcun; Gençöz, Tülin; Woody, Sheila (Wiley, 2010-03-01)
Recent findings have suggested some potential psychological vulnerability factors for development of obsessive-compulsive (OC) symptoms, including cognitive factors of appraisal and thought control, religiosity, self-esteem and personality characteristics such as neuroticism. Studies demonstrating these associations usually come from Western cultures, but there may be cultural differences relevant to these vulnerability factors and OC symptoms. The present study examined the relationship between putative vu...
