Brief Summary

Our objectives are to determine whether the 4DSQ is valuable for Turkish-speaking patients living in Belgium who face language barriers-meaning they are not fluent in Dutch or French-and have psychological complaints, and to provide better support within the primary healthcare system for general practitioners (GPs). We will use individual semi-structured interviews with GPs who applied the Turkish 4DSQ to diagnose only Turkish-speaking patients with mental health issues.

Interventions

Turkish translation of the Four-Dimensional Symptom Questionnaire DIAGNOSTIC_TEST

A qualitative interview study will be conducted, where Belgian general practitioners (GPs) who do not speak Turkish will administer the Turkish version of the 4DSQ to Turkish-speaking patients with psychological complaints and language barriers. The study will primarily be conducted in the form of two interviews. In the first phase, Belgian general practitioners who do not speak Turkish and wish to participate in the study will be introduced to the study's purpose, plan, and the Turkish version of the 4DSQ. The participating general practitioners will administer the 4DSQ to patients who speak Turkish but do not understand Dutch or French. The participation of at least 10 general practitioners is planned. GPs who applied the 4DSQ to target patients and created the treatment follow-up scheme will be interviewed again. Interviews will be audio-recorded. The privacy of participants will be ensured by altering data that could identify individuals. After transcription, the recording
