Driving under the influence of alcohol and substance use is an important traffic problem that caused many people in the world to lose their lieves. Many features that are important in terms of driving adversely affected under the influence of alcohol and substance and therefore impaired driving behavior arises in drivers. The most effective way to fight for prevent this impaired driver behavier is the restrictions and regulations imposed on drivers in traffic related to alcohol and drug use. Nevertheless, in the literature, some drivers continue to impaired driving function with a risky traffic behavior, in which the driver personality (risk-taking, thrill-seeking, self-control), psychopathological (substance abuse, personality disorders, mood disorders, attention deficit hyperactivity disorder, post-traumatic stress disorder, anxiety, anger and aggression), and many other neuropsychological features are considered to have a relationship with this situation. In this article psychological, psychopathological and neuropsychological studies have examined regarding drive under the influence of alcohol and drug.

Alkol ve Madde Etkisi Altında Araç Kullanımı ile İlişkili Psikolojik Faktörler

Öz

Alkol ve madde etkisi altında araç kullanımı, dünyada birçok insanın hayatını kaybetmesine neden olan önemli bir trafik sorunudur. Alkol ve madde etkisi altında sürücülerde sürüş açısından önemli olan birçok özellik olumsuz etkilenmekte ve bu nedenle sürücülerde bozulmuş sürücü davranışı ortaya çıkmaktadır. Bozulmuş sürücü davranışını engellemek için belirlenen en etkili mücadele yollarından birinin ise trafikte sürücülere alkol ve madde kullanımına ilişkin getirilen kısıtlamalar ve yasal düzenlemeler olduğu kabul edilmektedir. Buna rağmen literatürde, bazı sürücülerde riskli bir trafik davranışı olan bozulmuş sürücü davranışının devam ettiği; bu sürücülerde kişilik (risk alma, heyecan arayışı, özdenetim), psikopatolojik (madde bağımlılığı, kişilik bozuklukları, duygu durum bozuklukları, dikkat eksikliği hiperaktivite bozukluğu, travma sonrası stres bozukluğu, anksiyete, öfke ve saldırganlık) ve nöropsikolojik birçok özelliğin bozulmuş sürüşle ilişki ve etkisinin olduğu değerlendirilmiştir. Bu yazıda alkol ve madde etkisi altında araç kullanımına ilişkin yapılan psikolojik, psikopatolojik ve nöropsikolojik çalışmalar incelenmiştir.
