The content of this study is about a survey comparing the health behaviour and the lifestyle of students in occupational therapy and in civil engineering and construction management at the college Campus Wien. First, in order to clarify the expressions of health behaviour and lifestyle, they are defined precisely. As a next step, each of the five different health models namely the Health Belief Modell (HBM), the Protection Motivation Theory (PMT), the Theory of Reasoned Action (TRA), the Theory of Planned Behaviour (TBP) and the Health Action Process Approach (HAPA) is described. These models are illustrated by means of four international surveys similar in respect of content. The second part explains the development and the transfer of the questionnaire which is the basis for the further data collection. 27 of these were filled out by students of both courses of studies and afterwards analysed. The results of both programs of studies were compared, discussed and contrasted with further surveys. According to the executed survey, in contrast to students of occupational therapy, civil engineering and construction management students are feeling pain more often, but are less overstrained. Furthermore, students who study occupational therapy are more likely to call upon psychotherapeutic and psychiatric services and have a stronger believe in their influence on their personal health. In respect of the health behaviour, a significant difference of a change in attitudes, manners of drinking, alcohol consumption, drug consumption and weekly time scheduling occurred in the last three years. According to the survey, students of occupational therapy show a positive trend to a healthier behaviour. In contrast, students of civil engineering and construction management have better results in sports. Moreover, the survey illustrates slight differences between food, smoking habits, and weekly scheduling. In conclusion, the results of the survey show that a study focusing on health generally influences the personal health behaviour in a positive way.
