Validity and reliability of Malay version of the job content questionnaire among public hospital female nurses in Malaysia

Background: The Job Content Questionnaire (MJCQ) is an established self-reported instrument used across the world to measure the work dimensions based on the Karasek s demand-control-support model.

Except for psychological job demand (Cronbach s a 0.51), the remaining 3 a values for 3 subscales (job control, social support, and physical demand) were greater than 0.70, indicating acceptable internal consistency. However, an item was excluded due to poor item-total correlation (r
