characteristics model on nurses' work motivation and involvement in intensive care units, at Mansoura University
Hospitals. Design: Descriptive correlational design was used. Methods: The study was conducted at all intensive care
units at three Mansoura University Hospitals. The total sample was 180 nurse. Three tools were utilized; Job
Diagnostic Survey, Work Extrinsic and Intrinsic Motivation Scale, and Job involvement Scale. Results: More than
half of nurses had average level perception of job characteristics and almost two thirds of them had modest level of job
satisfaction. More than half of nurses obligated high level of work motivation, and moderate level of work
involvement. Conclusion: Based on the study findings, it was concluded that there was statistically significant positive
relationship between levels of job characteristics and job satisfaction, and there was no statistically significant
