Although ward behaviour rating scales for use with long-stay psychiatric patients by nurses have been in existence for many years, their content tends to reflect the opinions of psychiatrists and psychologists rather than those of nurses. An analysis of five commonly used rating scales illustrates the lack of agreement on what should be included. The opinions of 76 nurses from four separate hospitals were sought, using a 34-item questionnaire, to establish what areas of content were considered important in nursing practice. Apart from agreement on general content, consideration should also be given to the presentation of individual items of ward rating scales.
