AIM: To translate the MISSCARE Survey into Swedish and establish its validity and reliability by evaluating its psychometric properties.

BACKGROUND: Missed nursing care is defined as any aspect of required nursing care that is omitted or delayed. The consequence of missed nursing care is a threat to patient safety. The MISSCARE Survey is an American instrument measuring missed nursing care activities (part A) and its reasons (part B).

METHODS: The translation was accomplished according to World Health Organization guidelines, focusing on a culture adaptation. Acceptability, construct validity, test-retest reliability and internal consistency were analysed. The Revised Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0).

RESULTS: The translation and culture adaptation needed several revisions. A total of 126 nurses answered the test and retest which showed acceptability of missing data. The factor analysis revealed a lack of fit to data for the original factorial structure in part B, while further analysis provided results suggesting a modification based on omitting six items. The internal consistency for part B and its subscales showed good results.

CONCLUSIONS: The MISSCARE Survey-Swedish version is a reliable and valid instrument, with good psychometric properties.

RELEVANCE TO CLINICAL PRACTICE: More reliable language versions of the instrument enable national and international comparisons that could be valuable for nursing managers and/or directors of nursing who are responsible for quality of care and patient safety in the strategic care planning process.
