Psychometric adaptation of the driving anger expression inventory in a Chinese sample

The purpose of this study was to assess the psychometric properties and the factorial structure of the Driving Anger Expression Inventory (DAX) in a Chinese sample. We also explored the relationships among driving anger expression, general anger expression, and driving outcomes. Three hundred and fifty-eight drivers completed the Chinese version of the DAX, the Anger Expression Scale (AX), the Dula Dangerous Driving Index (DDDI) and a questionnaire about several types of traffic violations. A confirmatory factor analysis of the Chinese DAX yielded a four-factor solution with 20 items. This solution showed the best goodness of fit of the data and acceptable reliability. The validity of the revised DAX was also verified. The aggressive expression forms were positively correlated with dangerous driving behaviors. Using the vehicle to express anger was associated with fines. The aggressive forms were also positively correlated with general anger expression-out and negatively correlated with general anger control. The adaptive expression of anger was positively correlated with anger control but negatively correlated with dangerous driving behaviors, penalty points and fines. Furthermore, young drivers (<30 years old) reported more personal and physical aggressive expressions of anger than other drivers. Gender differences were only found in some age groups. Thus, the revised DAX was confirmed to be a reliable and valuable instrument to measure forms of driving anger expression in traffic environments in China. As a new automobile consumption market, China has witnessed a dramatic increase in the number of vehicles and drivers on its roads over the past 10 years. of drivers increased from 42 million to 173 million. The rapid increase in the number of drivers has resulted in a large number of novice drivers whose driving style differs from that of US drivers. In particular, Chinese drivers concentrate on driving skills and capabilities, whereas US drivers concentrate on practical driving safety guidelines. For example, Chinese drivers seldom use running lights during rainy or snowy weather, and less than half of drivers use turn signals to indicate their intention to change lanes (Zhang, Huang, Roetting, Wang, & Wei, 2006). Therefore, the traffic environment in China differs from that in other countries. Chinese drivers are involved in a greater number of traffic accidents than drivers in the US and
