: This study is part of the project “A new generation of Patient-Reported Quality Measurements in Mental health and Addiction Services (PRQMs-MAS)”, funded by the Norwegian Research Council (project number 331891). The study was conducted as a quality assurance project. According to the joint body of the Norwegian Regional Committees for Medical and Health Research Ethics, research approval is not required for quality assurance projects. Research Director Frederik Frøen of the NIPH Healthcare Services Division approved the Data Protection Impact Assessment (DPIA) for the project. The study was performed in accordance with relevant guidelines and regulations, including the Declaration of Helsinki. Written informed consent was obtained from all individual participants included in the study, and Health Data Service granted an exemption from confidentiality obligations (“dispensasjon fra taushetsplikten”), which permitted the collection of background data for both respondents and non-respondents.

: Informed consent was obtained from all participants. Returning the completed questionnaire constituted consent, which is the standard procedure in all patient-experience surveys conducted by the Norwegian Institute of Public Health. Patients were informed that participation was voluntary. Consent for participation in subsequent follow-up surveys was obtained through a separate opt-in question included in the baseline questionnaire, accompanied by a brief project description and a link to further information (see Supplementary Material ). Only data from the baseline survey were used in the present study.
