The Determinants of posttraumatic growth and posttraumatic stress among motor vehicle accident survivors: personality, coping mechanisms, and ruminations

Çağlayan, Pınar
The experience of traffic accidents is a quite frequent adversity, especially in Turkey. Although traumatic events result in negative psychological consequences, their positive outcomes have also been examined in psychology literature. The current study aimed to examine negative and positive consequences, namely posttraumatic stress (PTS) and growth (PTG) of traffic accident survivors in Turkey. Factors related to PTS and PTG were examined based on the Multivariate Risk Factor Model and Model of Life Crises and Personal Growth, respectively. These factors were personality characteristics, event related variables (timing and severity of the accident), and post trauma variables (coping and ruminations). Furthermore, the relationship between PTG and the change in the positive driver behaviors among driver survivors was examined based on the combination of the Conservation of Resources Theory and Model of Life Crises and Personal Growth. The sample consisted of 225 adult traffic accident survivors (105 males, 120 females). The findings showed that in the last step of the regression analysis, perceived severity of the accident, helplessness and fatalistic coping, and intrusive rumination were associated with PTS. Furthermore, perceived severity of the accident, problem solving coping, and deliberate rumination were related to PTG. The subscales of PTS and PTG were related to different variables. Mediation analyses were conducted to examine the relationship between predictive variables, and PTS and PTG. The results were discussed in relation to the hypotheses of the current study and literature findings, strengths and clinical implications, and limitations and directions for future studies were presented.


The Social psychological predictors of pedestrian behaviors
Demir, Başar; Özkan, Türker; Department of Psychology (2017)
Pedestrian violations are a major traffic safety problem in low and middle-income countries. Pedestrians have a high responsibility in accidents due to their unsafe behaviors. The problem worsens further by the scarcity of theory-based research to improve our understanding of pedestrian violations. The current behavioral classification on road user behavior suggest that skill-based, rule-based, and knowledge-based performance levels lead to violations, errors, and positive behaviors. These are distinct doma...
The path from traffic accident to posttraumatic stress, posttraumatic growth, and driver behavior change: an examination with rumination and transtheoretical model
Kaçan, Bilgesu; Özkan, Türker; Gençöz, Tülin; Department of Psychology (2017)
The traffic accident is one of the traumatic events with their high occurrence rates, deathful results and psychological consequences. While post-traumatic stress (PTS) is one of the negative psychological causes of traffic accidents, positive psychological experiences such as post-traumatic growth also can be experienced. These experiences with their vital effects have an impact on driver behavior change. In this thesis, the path from traffic accident to PTS, PTG, and driver behavior change was examined wi...
Job stress, burnout, and aberrant driving among professional drivers of old age
Fındık, Gizem; Lajunen, Timo; Department of Psychology (2016)
Commercial vehicles are involved in roughly 18% of all traffic accidents and 27% of all fatal traffic accidents in Turkey. These numbers highlight the need to investigate why professional drivers are involved in traffic accidents. Although the issue has often been on the agenda of the media, a similar impact occurred neither in scientific nor policy or applied domains yet. Therefore, the main purpose of this study is to investigate the relationship between job stress, burnout, and driving related outcomes (...
The role of driver behavior, skills, and personality traits in traffic accidents
Sümer, Nebi; Özkan, Türker (2002-12-01)
Traffic accidents area leading cause of death in Turkey. Past research on traffic psychology has clearly revealed that human factors play the chief role in road crashes, and driver behaviors, skills, risk-oriented personality traits, and psychological symptoms are the specific contributors of these factors. The present study was conducted to examine the role of driver behaviors, skills, some personality constructs, and psychological symptoms in predicting accidents and negative driver outcomes. A total of 3...

Keskin, Fatih; Yenilmez, Firdes; Colak, Mithat; Yavuzer, Ipek; Düzgün, Hafize Şebnem (2010-06-05)
In the recent years, traffic incidents sharply increase in Turkey. Although traffic regulations strictly applied in Middle East Technical University Campus (METU), Ankara, Turkey, this increasing trend also present in the campus. To prevent traffic incidents, it is crucial to understand where and how they take place, the relations among the incidents, and the locations. The aim of this study is to make a traffic pattern analysis concerning time and locations within METU Campus using spatial data analysis to...
