This study examined the differences between nurses' (N = 3,337) scores on organizational support, workload, satisfaction, and intent to stay between Magnet, Magnet-aspiring, and non-Magnet hospitals. The study was conducted using the Individual Workload Perception Scale, a valid and reliable tool with 32 Likert scale items, with nurses from 11 states, 15 institutions, and 292 diverse units. Results indicate that nurses at Magnet hospitals had significantly better scores on all subscales. Furthermore, nurses from Magnet-aspiring hospitals had better scores than did nurses from non-Magnet facilities. Conclusions of the study indicate that the Magnet program is meeting its intended goal: to provide a professional practice environment for staff nurses. Nurse executives may consider using the Individual Workload Perception Scale as a way to assess their organization's culture as it relates to professional practice of the registered nurse.
