Background and purpose: The prevalence of delirium during hospitalization is high in older patients and there is evidence of staff regarding them as unpopular or a burden. This study aims to develop an instrument examining nurses' attitudes toward patients with delirium.
Methods: Stages included (a) content identification, (b) content development, (c) content critique, (e) pilot study with a test-retest reliability, (f) field study consisting of psychometric testing of the internal consistency and construct validity.
Results: The Cronbach's alpha was 0.89 and the stability reliability was acceptable. The factor analysis resulted in three factors explaining a total of 56.5% of the variance. hese factors are "beliefs," "behavior," and "emotions," explaining 37.025%, 12.792%, and 5.652% of variance.
Conclusions: The Attitude Tool of Delirium (ATOD) is a reliable and valid instrument for the assessment of attitudes toward delirium.
