Interpersonal facilitation and job dedication as separate facets of contextual performance.

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 rated each aspect of performance), and 515 of these mechanics also completed self-report individual difference measures. Correlations between performance ratings and individual difference variables support distinguishing task performance from interpersonal facilitation but not from job dedication. Thus this study suggests the need to redefine task performance to include motivational elements of job dedication. Then task performance would include task proficiency and motivation to perform one's own tasks effectively, and contextual performance would include interpersonal skills, the motivation to maintain good working relationships and help others perform their tasks.
