The global functioning evaluation: Kennedy Axis V compared with WHODAS 2.0

The study aims to compare psychometric properties and clinical utility of Kennedy Axis V (K Axis) and 12-items version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), a comparable version of the 36-items one included in DSM-5, comparing them with other significant instruments for the assessment of personality. A sample of 25 clinical inpatients of a therapeutic community in Northern Italy was assessed with different tools: K Axis, WHODAS 2.0, IPO, SCL-90-R and SIPP-118. K Axis showed low internal consistency, unlike WHODAS 2.0. Moreover, significant correlations were found between both WHODAS 2.0 and K Axis and IPO and SIPP-118. However, no significant correlations emerged between K Axis and WHODAS 2.0. Even if further investigation will be needed, such as the increase of the sample and the update of the WHODAS version, K Axis and WHODAS 2.0 has proven to be useful tools for the evaluation of global functioning; however, while WHODAS is more consistent from a psychometric point of view, K Axis presents a multidimensional view of the functioning of the patient.
