Background Only a few anxiety assessment tools that nurses may administer are validated forthe Portuguese population exist in the literature. Thus, this study aimed to translate and culturally adapt the Hamilton Anxiety Scale for the Portuguese population and assess its psychometric properties in a sample of adult people with mental health disorders. Methods This psychometric study uses a convenience sample of adult patients with mental health disorders. Results The confrmatory factor analysis confrmed the two factors of the original version of the tool. The internal consistency (Cronbach’s alpha) was high, at .92, as well as the inter-rater reliability (intraclass correlation coefcient) (.91). Conclusions The validity and reliability of the instrument are supported. However, the Hamilton Anxiety Scale should be used cautiously in the Portuguese population because the correlation with the “Anxiety State” subscale of the State-Trait Anxiety Inventory is not statistically signifcant.
