Abstract
Men and women differ in the manifestation of depression. At the same time, there is a
lack of gender-sensitive depression questionnaires in Germany. This study investigated
the Gender-specific binary depression screening version (GIDS-15) in a further validation
step. In a two-armed, pragmatic single-blind randomised controlled clinical trial, we first
investigated the psychometric properties and the sensitivity to change in the GIDS-15 in a
sample with subclinical depression (N = 203). In addition, we then analysed sex differences
between the intervention and waiting control group over time. We were able to demonstrate
adequate to acceptable internal consistency as well as convergent construct validity of the
GIDS-15. Additionally, we were able to demonstrate the sensitivity to change in the GIDS-
15. Using a linear mixed model, we calculated a three-way interaction between intervention
group, sex, and time (p = 0.017). We found an increase in the intervention effect for men
over time. Conclusions: The GIDS-15 proves to be a solid and practical screening tool for
the gender-sensitive assessment of depression in Germany. It can be used for progression
and intervention diagnostics, although the intervention effect that was found can only be
interpreted to a limited extent due to significant sample size differences between men and
women. Limitations of our study and practical implications are discussed.
