and its effect in these aspects has received less attention. One of the nursing models used in improving sexual
function and adaptive behaviors after surgeries is Roy's adaptation model. Aim: The present research aimed to
evaluate the effect of the nursing approach based on Roy's adaptation model on sexual function and health-promoting
behaviors of women after hysterectomy. Design: A quasi-experimental research design (Two-Groups, Time series
pre /post-test quasi-experimental design) was used. Sample: A purposive sample of 90 women after hysterectomy
operations. Setting: The present research was conducted at Obstetrics and Gynecology department and the outpatient
clinics at Benha university hospital. Tools: four tools utilized included: self-administered questionnaire, Female

with highly statistical difference. Additionally, nearly two-thirds of the research group satisfied of Roy's adaption
model for hysterectomy. Conclusion: the implementation of the nursing approach based on Roy's adaptation model
had a highly significant improvements in women' sexual function, the women became highly adapted with
