Abstract: The concepts of self care of health (the goal of self care) are explored in relation to the self care nursing model. It is a basic premise of this model that the client be involved to the fullest possible extent in regarding or developing self care skills. It is proposed that individuals differ in respect to their readiness of such involvement and effort in their own health work and, hence, inability to benefit from the application of the self care nursing model. The study aimed at developing a means of identifying and predicting these differences. It was hypothesised that the individuals perceptions and beliefs about heath, his attribution about the location of blame for illness and the extent to which he perceives himself as having control over the contingencies of his behaviour, would all systematically influence his readiness to engage in self care. A health questionnaire designed to obtain data on individual health related beliefs and practices was constructed. This was mailed to a random sample of non-academic staff from one of the universities. A combination of univariate and multivariate analyses of the 86 completed questionnaires showed four major variables to be significantly interrelated. The pattern of relationships which emerge between responses to other items in the questionnaire cast further light on the complex determinants of health behaviour. Of particular interest is the suggestion that the way health is defined is a crucial factor. Use of the principal axes method of factor allowed a shortened version of the original questionnaire to be produced. The profile yielded by scores on this instrument, not only describes the client in terms of four major health related variables, but can also be used to predict readiness to benefit from a self care nursing approach
