Design outcomes

Primary

Measure	Time frame
Severity of suicidal symptomatology. Assessed once at the time of study participation during a routine follow-up visit in the endocrinology outpatient clinic. Suicidal symptomatology will be assessed using a standardized questionnaire. The Skala Suizidales Erleben und Verhalten (SSEV) will be used for this purpose. The primary outcome parameter is the total SSEV score, reflecting the severity of suicidal symptomatology captured by the questionnaire.	—

Measure	Time frame
Concordance/discrepancy between questionnaire-based suicidality and retrospectively extracted clinical documentation of suicidality from the indication/recommendation letter and admission documentation. Exploratory associations between retrospectively collected routine blood parameters (total cholesterol, leukocyte count, TSH, estradiol, testosterone) and suicidal symptomatology assessed once by SSEV.	—
