Purpose: The purpose of this study was to adapt the community version of the Self-Care Requisites Scale so as to be able to use it in a hospital context and to validate the new version in patients with schizophrenia.
Design and methods: An initial phase was conducted to develop the questionnaire by means of a panel of experts. The validation of the psychometric properties was conducted using a sample of 264 patients.
Findings: The new version showed good internal consistency and stability over time. The confirmatory factor analysis showed that the theoretical model fit the self-care requisites proposed in Orem's nursing theory from which it was drawn.
Practice implications: The new version is a valid and reliable instrument for use in clinical practice.
