“The Mental Health Recovery Star: Validation study and features of the Italian version” (Full article)
This study evaluated the acceptability and psychometric properties (convergent validity, test-retest reliability and inter-rater reliability) of the Italian version of the Mental Health Recovery Star (MHRS).Convergent validity was assessed by examining readings on MHRS scales and the relevant scales of other validated tools: the Health of the Nation Outcome Scales (HoNOS), World Health Organisation Quality of Life-BREF (WHOQoL-B) and Global Assessment of Functioning (GAF). Temporal stability was tested by 117 service users completing the MHRS two months apart. Finally, inter-rater reliability was examined by 42 keyworkers giving readings for a clinical case, which was described and discussed at the end of a training session.
Service users and keyworkers perceived the Recovery Star as acceptable and easy to use. Convergent validity was demonstrated and there was good test-retest reliability for all areas of the Star. Cohen's kappa coefficient was calculated as a measure of inter-rater reliability and all pairs reached acceptable levels of at least 0.70. The authors note that using a larger number of case studies would have made the finding more generalisable*.
* Placentino and colleagues refer to Killaspy et al. (2012), in which keyworkers assessed 85 service users, but since these readings were taken without collaboration with service users or using a written case study, we cannot know what information was being used by each keyworker and it is likely that they were missing important information upon which to base their readings. These and other limitations of Killapsy et al.’s method are discussed in letters published in the British Journal of Psychiatry (e.g. MacKeith, 2012).
