People driving under the influence of alcohol are commonly referred to as drunk drivers, or drink-drivers. When charged with this as a crime, it may either be referred to as a DUI (Driving Under the Influence) or a DWI (Driving While Intoxicated), where a DUI is generally considered to be a lesser crime. Studies have been performed to identify commonalities between severe drunk drivers. Laws are also in place to protect citizens from the consequences incurred by drunk drivers. == Common personality traits == Although situations differ and each person is unique, some common traits have been identified among drunk drivers. In the study "personality traits and mental health of severe drunk drivers in Sweden", 162 Swedish DUI offenders of all ages were studied to find links in psychological factors and characteristics. There are a wide variety of characteristics common among DUI offenders which are discussed, including: "anxiety, depression, inhibition, low assertiveness, neuroticism and introversion".〔Hubicka, Beata. "Personality traits and mental health of severe drunk drivers in Sweden."〕 There is also a more specific personality type found, typically more antisocial, among repeat DUI offenders. It is not uncommon for them to actually be diagnosed with antisocial personality disorder (ASPD) and exhibit some of the following personality traits: "low social responsiveness, lack of self-control, hostility, poor decision-making lifestyle, low emotional adjustment, aggression, sensation seeking and impulsivity".〔 It is also common for offenders to use drinking as a coping mechanism, not necessarily for social or enjoyment reasons, when they are antisocial in nature and have a father with a history of alcoholism. Offenders who begin drinking at an earlier age for thrills and "fun" are more likely to be antisocial later in their lives. The majority of the sample, 72%, came from what is considered more "normal" circumstances. This group was older when they began drinking, came from families without a history of alcoholism, were relatively well-behaved as children, were not as physically and emotionally affected by alcohol when compared with the rest of the study, and had the less emotional complications, such as anxiety and depression. The smaller portion of the sample, 28%, comes from what is generally considered less than desirable circumstances, or "not normal". They tended to start drinking heavily earlier in life and "exhibited more premorbid risk factors, had a more severe substance abuse and psychosocial impairment."〔 Various characteristics associated with drunk drivers were found more often in one gender than another. Females were more likely to be affected by both mental and physical health problems, have family and social problems, have a greater drug use, and were frequently unemployed. However, the females tended to have less legal issues than the typical male offender. Some specific issues females dealt with were that "almost half of the female alcoholics had previously attempted to commit suicide, and almost one-third had suffered from anxiety disorder." In contrast with females, males were more likely to have in-depth problems and more involved complications, such as "a more complex problem profile, i.e. more legal, psychological, and work-related problems when compared with female alcoholics."〔 In general the sample, when paralleled with control groups, was tested to be much more impulsive in general. Another commonality among the whole group was that the DUI offenders were more underprivileged when compared with the general population of drivers. A correlation has been found between lack of conscientiousness and accidents, meaning that "low conscientiousness drivers were more often involved in driving accidents than other drivers." When tested the drivers scored very high in the areas of "depression, vulnerability (to stress), gregariousness, modesty, tender mindedness", but significantly lower in the areas of "ideas (intellectual curiosity), competence, achievement striving and self-discipline."〔 The sample also tested considerably higher than the norm in "somatization, obsessions-compulsions, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoia, psychoticism", especially in the area of depression. Through this testing a previously overlooked character trait of DUI offenders was uncovered by the "low scores on the openness to experience domain."〔 This area "includes intellectual curiosity, receptivity to the inner world of fantasy and imagination, appreciation of art and beauty, openness to inner emotions, values, and active experiences." In all these various factors, there is only one which indicates relapses for driving under the influence: depression.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Drunk drivers」の詳細全文を読む スポンサード リンク
