U. Funke et H. Schuler, VALIDITY OF STIMULUS AND RESPONSE COMPONENTS IN A VIDEO TEST OF SOCIAL COMPETENCE, International journal of selection and assessment, 6(2), 1998, pp. 115-123
Various stimulus components (video, orally-presented questions) and re
sponse components (multiple-choice, written, orally-given replies) of
situational judgement tests of occupational social competency were inv
estigated as to their impact upon the validity for a behavior-oriented
role playing criterion while keeping test content constant. The stimu
lus component video alone had no impact upon validity. The response co
mponents contributed to validity. Validity increased with improved fid
elity of response components. Concerning stimulus-response-combination
s, the validity of two video tests (r = 0.17 and r = 0.36) was not hig
her than the validity of similar oral questioning (r = 0.13 and r = 0.
37) but was significantly lower than a situational interview (r = 0.59
). Response fidelity proved to be a bottleneck regarding validity of v
ideo tests. As a result, it is recommended that, in order to maximize
validity of video and multimedia efforts, the developers of video- and
multimedia tests focus special attention on response fidelity.
