The shortened version of the Adolescent Stress Questionnaire (ASQ-S; Sweden): a validation study in United Kingdom adolescents

stressors in adolescence (e.g. 4-6). Specifically, the structural validity of ASQ scores has been substantiated by confirmatory factor analysis (CFA), intercorrelations that indicated related but distinctly different constructs, and convergent validity analyses. Nevertheless, on-going inquiries into psychometric properties of ASQ scores warrant our attention. Byrne et al. (4) developed the 56-item Adolescent Stress Questionnaire as an index of stress consisting of items forming 10 different stress

Determine the safe transport of dangerous goods route

The methods of conflict situations assessment were analyzed, and it was established that the main shortcoming is the disregard of the probability of occurrence of the RTA involving an individual road user. Based on the factor analysis conducted, the non-linear model of the probability of the RTA occurrence in the transport network segments was developed. Also, the model of the probability of the RTA occurrence in transport junctions was improved. It will enable, if using respective optimization
