Construct Validity of Instruments Assessing Clinical
Competence. Edition No. 1
VDM Publishing House, May 2009, Pages: 196
There is a need to evaluate the evidence for
construct validity of high stake assessment tools
used for assessing clinical competence of
physicians. The focus has been on reliability which
is a necessary but not sufficient condition for
validity. This monograph will discuss psychometric
evaluation of assessment instruments focussing on
validity. The research addressed in this monograph
has utilized the multitrait multimethod matrix
(MTMM) approach introduced by Campbell and Fisk and
deliberated on its historical background and
usefulness. Three traits, doctor-patient
relationship, clinical competence, and communication
skills were assessed in OSCEs, ITERs and clinical
assessments. There was evidence for both
convergent and divergent validity for clinical
competence, doctor-patient relationships, and
communications. There is evidence for the construct
validity of all three traits across three methods.
The MTMM approach,currently underutilized, could be
profitably employed to estimate the degree of
evidence for validating complex constructs like,
clinical competence.
