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 with rumination type and stages of Transtheoretical Model (TTM) mediation. To examine stages of TTM, two scales were translated and adapted to Turkish. The data of 409 adult traffic accident survivors was used for adaptation analysis; the data of 234 adult traffic accident survivors was used for other analysis. While factor analysis showed difference for one scale, other scale showed perfect fit with original version. Pre-contemplation stage, contemplation stage, and action-maintenance stage caused partial metiation in the relationship between perceived severity of event and PTS; and between severity of event and PTG; and between PTS and PTG; when rumination type was included analysis as mediator variable full mediation was found. In terms of relationship between PTS/PTG and positive driver behavior change, action-maintenance stage was found as a significant mediator variable. The detailed results were presented and discussed; the limitations, strengths, clinical implications of study; suggestions for future studies were presented.

The Relationship between traumatic life experiences, locus of control and driver behaviors
Öz, Cansu; Özkan, Türker; Öz, Bahar; Department of Psychology (2016)
The aim of the current study was to investigate effects of traumatic life experience on driver behaviors by measuring their world assumption and posttraumatic growth and to evaluate indirect effect of locus of control between world assumptions and driver behaviors. The total of 533 Turkish drivers participated to study and they were assigned to study groups in terms of reported traumatic experience. In traffic trauma group, there was 120 drivers who reported experiencing only traffic accident. 231 drivers w...
Self-regulatory driving practices of old and young drivers
Azık, Derya; Özkan, Türker; Department of Psychology (2015)
The aim of the current study was to investigate self-regulatory driving practices of old and young drivers by examining underlying factors and possible benefits on drivers’ aberrant behaviors. 258 active male drivers (120 older, 138 younger) participated in the study. Older drivers’ age range was determined as 60-75 and younger drivers’ age range was determined as 21-30. For testing motivator factors of self-regulatory driving practices, Health and Functional Abilities Scale (Molnar et al., 2013), Self-Rate...
The Relationship between traffic climate and driver behaviors: explicit and implicit measures with Turkish and Chinese samples
Üzümcüoğlu Zihni, Yeşim; Özkan, Türker; Department of Psychology (2018)
Traffic fatality rates and driver behaviors show regional differences. It is assumed that perceived traffic climate in a given context are closely related to driver behaviors. The first part of the present study aims to test this assumption crossculturally. Specifically, in this part, the aim was to investigate the relationships between traffic climate and driver behaviors in Turkey and China. The results revealed that this assumption was supported partially. Perceiving traffic climate as externally emandin...
The Effects of psychological inoculation on drivers’ speeding behavior
Simser, Berfin Serenat; Özkan, Türker; Department of Psychology (2019)
Speeding is a widespread problem which can cause life threatening outcomes in traffic settings. The present study was aimed at measuring whether psychological inoculation (PI) based on an integrated model of Theory of Planned Behavior (TPB) and Prototype Willingness Model (PWM) can be used to reduce speeding behaviors of drivers. 95 male drivers aging between 19 and 30 took part in the study. As part of the PI intervention, all participants were given challenging sentences as exaggerated forms of their atti...
The Effect of implementation intention on speeding behavior: a simulator study
Tekeş, Burcu; Özkan, Türker; Department of Psychology (2018)
Intention was accepted as the major contributor to driver behaviors in the literature. The present thesis aimed to systematically review the literature on the association between intention and speeding behavior. Based on the results of the review, intention was found as the main contributor of speeding. In the next chapter, intention was aimed to manipulate by implementation intention to reduce speeding. Implementation intentions are self-regulatory ‘if-then’ plans, which are the subordinate concept of goal...
