The Prevalence of Insomnia in Patients With Psychiatric Disorders

QUALITY ASSURANCE PLAN & SOURCE DATA VERIFICATION

For quality assurance the Ethics Committee may visit the research sites. For each study participant, a paper based case report form (CRF) will be maintained. CRFs will be kept current to reflect subject status at each phase during the course of study. Data for statistical analysis will be stored in an electronic database. Data will be transferred manually from the paper CRF to the electronic data base. As for the paper based CRF, the data stored electronically will not contain any personal information by which the participant can be identified. Only trained project personnel will be authorized for entries into the electronic database and authorized persons will be identifiable for every entry they made. Routinely collected data during daily clinical practice will be transferred to the participant CRF (e.g. diagnoses and medication).

STANDARD OPERATING PROCEDURE The recruitment of the study participants is consecutive. In all study sites, all newly admitted patients will be registered on a list each day. This list will be available for the study physicians. From this list, patients who are visibly not eligible (involuntary stay, under custody) will be deleted. Depending on the capacities of the study physicians, within three days after admission, 1-15 patients will be selected from the patients remaining on the list per day. The selected patients will be asked whether they agree to participate in the study.
