Correction to: Quality of Life Research (2023) 32:3223–3234 https://doi.org/10.1007/s11136-023-03469-z
This correction addresses an error present in Table 3 within the manuscript. The error pertains to a formatting issue in the column documenting "Item fit (Q index)" values, in which one cell contains a missing value and selected other values are swapped. This discrepancy seems to have occurred due to format distortions.

Additionally, due to an omission of the editorial team in the publication process, the item content and Rasch Model parameters were not published in the final version of the manuscript. The following tables present the estimated model parameters and the translated content of the questionnaire. It is important to note that while this version has not undergone formal validation, it is a carefully reviewed translation of the validated German questionnaire (see also a full version including instructions presented at the end of this correction).
