This paper outlines a study, which provided a pilot for part of a larger research project, to investigate Nurses'conceptualizations of caring The report gives an overview of previous work related to defining the concept of care before outlining the study undertaken A sample of nine qualified nurses was used and Kelly's repertory grid technique employed to elicit constructs within the concepts of caring attitudes and caring behaviours Grid data were analysed using cluster analysis and nine common themes were identified These themes were largely supportive of previous research studies It is proposed that in developing a theory of care, a synthesis should occur between Nurses'conceptualizations of the concept and their professional practice
