“…CHAID is a type of decision tree technique. This technique can both be used as prediction (like logistic regression) and for detection of interaction between variables (Kass, 1980). The algorithm recursively splits up the dataset by detecting the best predictor of PTSD among the five sociodemographic characteristics, creating associated subgroups of high and low risk.…”

In this study, the lifetime prevalence of stressful events and current posttraumatic stress disorder (PTSD) Epidemiological studies on posttraumatic stress disorder (PTSD) in the United States show a lifetime prevalence rate of 5-10% and a current prevalence of 1-5% in adult populations (Breslau et al., 1998;Kessler, Chiu, Demler, Merikangas, & Walters, 2005;Kessler, Sonnega, Bromet, Hughes, & Nelson, 1995;Resnick, Kilpatrick, Dansky, Saunders, & Best, 1993). Large national surveys are relatively scarce, and only a few studies describe prevalence rates of PTSD in Europe. Lifetime (2-6%) and currentThe authors wish to thank TNS NIPO and especially Ralitza ILieva for data collection and data entry.

“…The best results were obtained with the 'chi-squared automatic interaction detector' (CHAID) growing method (Kass, 1980). The CHAID algorithm evalu- ates each one of the independent variables to find the categories that best split each node, starting from the root.…”

Source of head injury for pedestrians and pedal cyclists: Striking vehicle or road?

The potential effectiveness of vehicle-based secondary safety systems for the protection of pedestrians and pedal cyclists is related to the proportion of cases where injury arises by contact with the road or ground rather than with the striking vehicle. A detailed case review of 205 accidents from the UK On-the-Spot study involving vulnerable road users with head injuries or impacts indicated that contact with the road was responsible in 110 cases. The vehicle however was associated with a majority of more serious casualties: 31 (vehicle) compared with 26 (road) at AIS 2+ head injury level and 20 (vehicle) compared with 13 (road) at AIS 3+ level. Further analysis using a multivariate classification model identified several factors that correlated with the source of injury, namely the type of interaction between the striking vehicle and vulnerable road user, the age of the vulnerable road user and the nature of injury.
