Quality assessment instruments in nursing: towards validation.

The aim of this study was to explore the validity of the nursing quality assessment instruments, Monitor, Senior Monitor and Qualpacs. This follows recommendations in the literature for the need for more comprehensive validation of instruments than has been the case hitherto. A multiple triangulation research design was used which included observation of and interviews with nurses and patients as well as administration of the instruments with the same patients and a questionnaire completed by the nurses in charge on ward organisation and their approach to nursing care. Results reported here focus on our experiences of using the instruments, their inter-rater reliability and comparisons of instrument scores within medical, surgical and elderly care wards. Difficulties were encountered in using the instruments but most of these can be overcome given sufficient time for preliminary discussions. Inter-rater reliability of all three instruments taken as a whole reached acceptable levels, although some of the section score correlation coefficients were low, especially for Qualpacs. Convergent validity was achieved for the Senior Monitor-Qualpacs comparisons in four elderly care wards. The results were less clear for the Monitor-Qualpacs comparisons in seven medical and surgical wards. Explanations for the equivocal results are suggested and subsequent hypotheses were tested which supported these explanations.
