Development of the professional driver behavior questionnaire

Yılmaz, Şerife
The aim of the present study was to develop a comprehensive scale measuring professional drivers' driver behaviors. For this reason, a semi-structured interview form was prepared and applied to different professional driver groups in order to collect behavioral examples displayed in traffic context (Study 1). These examples were grouped based on Reason's taxonomy of human error and Professional Driver, Driver Behavior Scale (PDBQ) was developed. PDBQ along with some other behavior scales such as ODBQ and DBQ was applied to different professional drivers (Main Study). PDBQ items were factor analyzed, and 3-factor solution was found more appropriate. These factors were called as Incompliance Mobility (favor sustaining mobility over safe driving), Positive Professional Driver Behaviors (safe practices in traffic environment, such as caring about other road users, helping and/or warning others in need, supporting traffic flow etc.), and Inappropriate Benefits (gaining benefits in traffic by posing risk to other road users). Moreover, three different ANCOVA was conducted to compare a group of drivers in terms of the driver behaviors factors emerged in the PDBQ. Results revealed that the van and cargo drivers are more likely to want to gain benefits in traffic at the cost of performing lawless behaviors. Results of two studies were discussed in the light of literature, contributions and limitations of the study were mentioned in detail.


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...
Investigation and comparison of human factors in driving and attitudes towards disabled drivers: a study with disabled and non-disabled drivers
Bakır, Besime Anıl; Öz, Bahar; Department of Psychology (2016)
The current study firstly aimed to develop an attitude scale to measure attitudes towards disabled drivers in traffic environments (Study-1). During development of the scale process, to gain knowledge about disabled driving semi-structured interviews were conducted with 28 active drivers (12 disabled drivers, 16 non-disabled drivers). Interview results were analyzed and results provided a basis for the development of ‘Attitudes towards disabled drivers scale (ADDS). After that, in the main study, it was aim...
The Relationship between the health belief model constructs and driver behaviors: mediating role of driving skills
Özbay, İrem; Öz, Bahar; Özkan, Türker; Department of Psychology (2017)
The aim of the present study is to examine the relationship between driver behaviors (emphasized violations), the Health Belief Model (HBM) constructs, and driver skills. Although the HBM is a widely used model in health settings, there are very few studies investigating the model at traffic settings. In the present study a total of 505 drivers (217 female, 288 male) whose mean age was 27 participated. The Driver Behavior Questionnaire was used to measure driver behaviors; that is, violations within the sco...
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...
Assessment of computer-based and self-reported hazard perception skills among drivers : the role of personality and driving skills
Ünal, Ayça Berfu; Sümer, Nebi; Department of Psychology (2006)
The aim of the present study was to investigate the correlates and predictors of hazard perception skill among drivers. Specifically, it was examined whether novice and experienced drivers would differ from each other in terms of hazard perception skill. In addition, the role of personality factors and driving skills in predicting hazard perception among drivers was inspected. Drivers’ hazard perception skills were assessed by using both a computer-based hazard perception latency test (Turkish Hazard Percep...
