Accordingly, the present study aimed to evaluate the psychometric features of the patient health engagement scale (phe s) in Iranian patients suffering from breast cancer.Methods: This is a cross-sectional study. The sample size was estimated by multiplying the total number of items by ten. The sample size was estimated for this 5-item scale 128 breast cancer patients who referred to a specialized clinic in 2020. Content validity and reliability analysis were performed, and the data were analyzed using IBM SPSS26 software and R content validity package.Results: The ordinal alpha of thesample was 0.626, indicating an acceptable internal consistency. The analysis of the rash model revealed an acceptable infit and outfit MNSQ (685-932). The polychoric correlation coefficient within the items was 46, representing a moderate correlation. All the factor loadings had a high value (0>60), thereby confirming the single dimensionality of the scale.Conclusion: The phe scale has favorable reliability and validity to assess the patients’ emotional adjustment and their engagement in their health and self-management before designing and implementing any intervention.
