The stress and coping process questionnaire ("UBV") is a new situation-reaction instrument aiming at the multidimensional assessment of components and processes of stress and coping behavior. The subject evaluates on different scales his/her situation appraisals, emotional reactions, coping objectives and coping behaviors in relation to prototypical stressful situations as presented in three stages (begin, continuation, and positive or negative outcome). The article gives a summary of theoretical foundations of the questionnaire, its structure and scales, and a number of reliability and validity studies. The results of the studies suggest a great variety of possible applications of the questionnaire (which offers also preliminary stanine-norms) as in the clinical domain (e.g. anxiety disorders) as in the domain of health psychology. The instrument provides also intervention-oriented informations and applies to the evaluation of stress and coping treatment programs. It is available in a german, english and french version.
