Objectives: This study aimed to develop the Nursing Practice Scale for End-of-life Family conferences in critical care and to clarify the current status of nursing practice regarding family conferences.
Research methodology/design: We conducted a cross-sectional, self-administered questionnaire survey with 955 critical care unit nurses in 97 hospitals. Content validity, factor validity and criterion-related validity, known-group validity, internal consistency and test-retest reliability were evaluated. Data were then analysed statistically.
Setting: Adult intensive care units or high dependency units in Japan.
Results: Three factors with 39 items were extracted through item analysis and confirmatory factor analysis as hypothesised (Factor 1: Preparation, Factor 2: Discussion and Factor 3: Follow-up), and the mean score per item for each factor was 3.57, 3.73 and 3.75, respectively. Nurses who had any certification or had worked in critical care unit for >5 years had a significantly greater score than the others. The Cronbach's α were 0.86-0.96 and the intraclass correlation coefficients were 0.79-0.87.
Conclusion: The Nursing Practice Scale for End-of-life Family conferences in critical care is a valid and reliable scale. This study could effectively facilitate communication among patients, their families and healthcare providers.
