Brief summary: The DIPS (Diagnostisches Interview bei psychischen Störungen) is a structured interview to assess a variety of the most frequent psychological disorders. Its reliability and validity has been studied in clinical samples. Since structured interviews are also used in non-clinical samples like epidemiological research the investigators would like to conduct a study in a community sample to test the interview's reliability, validity and acceptance.

Detailed description: The DIPS (Diagnostisches Interview bei psychischen Störungen) is a structured interview to assess a variety of the most frequent psychological disorders. Its reliability and validity has been demonstrated in clinical samples. Also, studies have tested patients' and therapist's acceptance of the interview. Since structured interviews are also used in non-clinical samples like epidemiological research the investigators would like to conduct a study in a community sample to test the interview's reliability, validity and acceptance in this population (study aim 1). The investigators also plan to compare positive mental health and affective styles of the subsample of participants with no current or lifetime mental health illness to patients from the local outpatient treatment center at the Ruhr-University Bochum, who all reported at least one current mental illness (study aim 2). If the researchers obtain enough participants with no current mental health problem, but a history of at least one mental health illness, they will be included in the analysis for study aim 2 as well.

Since the data collection takes place during the Corona pandemic, participants will also be asked to give information about how they are affected, about their living situation and their media use over the course of half a year to describe the sample and to determine the impact of these factors on the incidence and course of mental illness (study aim 3).
