Jr. Vanscotter et Sj. Motowidlo, INTERPERSONAL FACILITATION AND JOB DEDICATION AS SEPARATE FACETS OF CONTEXTUAL PERFORMANCE, Journal of applied psychology, 81(5), 1996, pp. 525-531
This study attempts to refine the construct of contextual performance
by dividing it into 2 narrower constructs, interpersonal facilitation
and job dedication. Supervisors rated 975 U.S. Air Force mechanics on
at least 1 of 4 aspects of job performance (different supervisors rate
d each aspect of performance), and 515 of these mechanics also complet
ed self-report individual difference measures. Correlations between pe
rformance ratings and individual difference variables support distingu
ishing task performance from interpersonal facilitation but not from j
ob dedication. Thus this study suggests the need to redefine task perf
ormance to include motivational elements of job dedication. Then task
performance would include task proficiency and motivation to perform o
ne's own tasks effectively, and contextual performance would include i
nterpersonal skills, the motivation to maintain good working relations
hips and help others perform their tasks.
