to nurses and organizationAim: Investigate the relationship between nursing practice environment and counterproductive
work behavior among staff nurses at Gastroenterology Center Mansoura University. Method: Descriptive correlational
design was utilized, included 174 staff nurses working at Gastroenterology Center Mansoura University. Data was
collected by using two tools, nursing practice environment questionnaire, and counterproductive work behavior
questionnaire. Results: Revealed that the highest mean percentage (72.08%) was related to collegial nurse physician
relationships as a characteristic of nursing practice environment. While, the lowest mean percentage (63.94%) was
related to nurse participation in hospital affairs. As well as, the highest mean percentages of counterproductive work
behavior were related to abuse and withdrawal, while the lowest perception was related to sabotage. Also, there was a
highly statistically significant negative correlation between nursing practice environment and counterproductive work
behavior. Conclusion: Nursing practice environment was mainly characterized by good relationship and collaboration
between nurses and physicians, adequate policy and planning around patient care. Also, counterproductive work
behavior had low level of occurrence among staff nurses. This means good nursing practice environment decreased
counterproductive work behavior among staff nurses. Recommendations: Providing the chance for staff nurses to share
