Research

interRAI systems are particularly useful for research. An assessment provides a comprehensive summary of the clinical, functional and psychosocial characteristics of an individual. These data can be used in a wide range of observational or intervention studies.

The advantage is that the measures are standardised, have strong psychometric properties and are in extensive use in practice. The measures can be used to compare the study population with other groups using a wide variety of characteristics.

The derivative summary scales are also useful for measuring the severity of a problem or monitoring progress over time. interRAI Australia is able to assist researchers to access systems, training and suitable software for data collection.
