The questionnaires are accompanied by scoring sheets that provide detailed instructions as to how to code each element of the respective OSI ^[1]. We have strived to make these instructions as standardized as possible, and as such, for most of the elements, automatic or computerized scoring can be done. However, there are a few circumstances for which the rater's judgment is required. In such cases, we describe in detail the items to be taken into consideration. Nevertheless, there could be some, albeit fairly minor, disagreement as to the score for a given element. Obviously, principles of good research, such as blinded rating, if possible by more than one observer, should be applied in these cases.

The process of revising the OSI model has been on-going over several years, and is the result of multi-facetted considerations. The development of the specific OSI's has been one of the most important of these, whereby new questions relevant to a certain occupation are found to reflect issues of general relevance. For example, in reviewing major stressors for physicians: the possibility of malpractice litigation, or the need to appear in court as an expert witness, it became clear that while the likelihood is perhaps less for many other occupations than for...
