: For the present study, medical ethics approval was not necessary because particular treatments or interventions were not offered or withheld from respondents. Moreover, the integrity of respondents was not encroached upon as a consequence of participating in this study, which is the main criterion in medical–ethical procedures in the Netherlands [CitationRef removed]. This research was conducted according to the guidelines for good clinical practice [CitationRef removed]. The researchers did not make the questionnaire long so the burden on participants would be limited; the average time for completing the questionnaire was 20 min. In addition, the questionnaire contained measures that have already been used in many previous studies among older people, including the WHOQOL-BREF. Both researchers have a PhD; during the PhD trajectory, much attention was paid to ethical aspects of good research.
: Informed consent related to detailing the study (e.g., information about the purpose of the study) and maintaining confidentiality was observed.
