[Kennedy V Axis assessment in an Italian outpatient and inpatient population]

Kennedy Axis V or K Axis acts is an alternative tool to the DSM-IVTR Global Assessment of Functioning (GAF) Scale, that many researchers describe as a scale with poor inter-rater reliability and clinical utility. Unlike the GAF scale, K Axis provides a multidimensional and multiaxial approach to measure personal, social and interpersonal functioning in psychiatric outpatients and inpatients. In this study, we examined K Axis's inter-raters reliability by using it with an Italian clinical population.

Clinicians used Kennedy Axis V to assess global functioning among 180 inpatients, in 9 psychiatric services in Lombardia and Piemonte. Patients were divided into 4 different diagnostic groups, according to the DSM-IV-TR criteria.

Intraclass correlations between two independent raters's scores reveal high level of interrater reliability for all K Axis scales (0,633 < ICC < 0,813). Highly significant results in the Kruskal-Wallis test demonstrate that the patient diagnosis influence all the scales scores. Significant differences in patients functioning profiles in all K Axis scales, apart from Violence one, were noted between different diagnosis groups.

In this study high level of raters agreement was noted, even if K Axis scales were used in different mental health services from different clinicians. K Axis scales provide a useful profile of patient global functioning, in line with the specific pathology.
