Abstract—The study attempts to examine the psychometric properties of the job performance constructs by integrating the two subscales; task performance and contextual performance. Results from preliminary psychometric conclude that the nursing performance scale has good internal consistency and good criterion validity. A measure developed by Greenslade and Jimmieson was used as a reliable and valid tool in assessing nurses’ job performance. The results of exploratory factor analysis confirmed that the measurement scale used in this study satisfactorily met the standards of validity and reliability analyses. Exploratory factor analysis confirmed five dimensions of task performance namely: technical care, non-job specific behavior, provision of information, provision of support and coordination of care. Meanwhile, three dimensions of Contextual Performance namely: job-task support, interpersonal support and organizational support; as the dimensions that measure Job Performance constructs.

Index Terms—Job performance, task performance, contextual performance.
