Translation and Psychometric Validation of the German Version of the Iceland-Family Perceived Support Questionnaire (ICE-FPSQ): A Cross-Sectional Study.

Only 77 family members were analysed, below the 200 completed questionnaires the researchers had aimed for and the sample size recommended for checking item grouping. The paper-based response rate was around 30%, and active recruitment by ICU nursing staff was limited by staff resources. The study was done in six ICUs of a Swiss university hospital, so local practices and pandemic visiting rules may affect results. COVID-19 restrictions may have shaped families' perceptions of support. Some questionnaire items were open to interpretation, and the German version did not group exactly like the original. There is no score cutoff that says what counts as good or insufficient family support.

The authors declared no potential conflicts of interest and received no financial support for the research, authorship, or publication.

Do not read the average score of 43.8 out of 70, or the quality rating of 8.5 out of 10, as proof that ICU family support was adequate or that the questionnaire improves care. It was tested in only 77 family members, some items did not group as in the original questionnaire, and there is no cutoff for good or poor support.
