There is a growing body of evidence demonstrating the validity and reliability of the Outcomes Star.
For a summary of this evidence, download “The Outcomes Star: Unpacking the Evidence.”
The evidence and research assess two aspects of the Outcomes Star:
- The effectiveness of the Star as a keywork tool, assessing the extent to which:
- the Star measures the things that matter to service users
- the Star helps service users and practitioners to make sense of the situation and to make the changes they need to make.
- The validity of the Star as an outcomes tool – assessing the extent to which:
- The Star demonstrates change over time in a service (‘responsiveness’)
- The Star relates to the scores produced by other tools measuring the same construct (‘convergent validity’)
- The Star can be used consistently across workers (‘inter-rater reliability’)
- The Star can be used consistently over time (‘test-retest reliability’)
- The Star areas fit together coherently (‘internal consistency’ and ‘factor structure’)
