Type: article
Abstract: Introduction: The population of people with dementia (PWD) in Indonesia is increasing. Evaluating nurses' confidence in caring for PWD is crucial as it impacts the delivery of health services to PWD. In Indonesia, no instrument is available to measure a nurse's confidence in caring for PWD. This study aimed to report the translation process, validity, and reliability of the Confidence in Dementia (CODE) instrument for nurses. Materials and methods: This psychometric testing study was conducted from September to October 2021. The CODE instrument was translated using the Beaton Method in the first step. The second step was testing the content validity involving six experts using the Scale-Content Validity Index (S-CVI). After that, the researchers conducted a construct validity test using Pearson Product Moment and a reliability test using Cronbach’s Alpha that involved 115 nurses at a hospital in Yogyakarta, Indonesia. Results: S-CVI results of 1.00 indicate that the content of CODE is valid. All CODE items are also valid in construct validity as the Pearson Product Moment test results show a calculated r of 0.526 to 0.633. Moreover, the CODE reliability test revealed a Cronbach’s Alpha score of 0.770 (acceptable). Conclusion: The Indonesian language CODE is considered valid and reliable for measuring nurses' confidence in caring for PWD.
