Development and Validation of the Operational Definitions of the Defining Characteristics of the Nursing Diagnosis of Insomnia in the Occupational Health Setting.

PURPOSE: To develop and validate the operational definition (ODs) for each defining characteristic (DC) contained in the Nursing Diagnosis (ND) "insomnia" (00095) in the occupational health context. METHODS: Methodological study carried out in two stages, including a consensus of experts to develop the ODs (Stage 1) and an online Delphi panel, performed in two rounds, to validate them (Stage 2). FINDINGS: The 15 ODs proposed in Stage 1 were narrowed down to six validated ODs in the first round (diagnostic content validity index [DCVI] = 0.80-0.89). In the second round, five ODs were validated (DCVI = 0.80-0.94). Finally, the remaining four ODs were validated by the general consensus of experts. CONCLUSIONS: The ODs were validated, although there remains some doubt as to whether some of the DCs can be applied to the field of occupational health. IMPLICATIONS FOR NURSING PRACTICE: The ODs developed and validated could improve the diagnostic accuracy of the ND "insomnia" (00095) in the context of occupational health.
