Abstract
BACKGROUND: To date, neither the original English nor any of the translated versions of the Sexual Complaints Screener for Women (SCS-W) have been tested for their psychometric properties. AIM: To evaluate the validity and utility of the German version of the SCS-W by assessing content, convergent, and discriminant validity.Entities:

FSFI = Female Sexual Function Index; SCS = Sexual Complaints Screener.
Items 1 to 4 correspond to individual FSFI items for each subscale in the specific order that they are presented in the original FSFI questionnaire.
P value is significant at less than 0.005; all other P values are significant at less than 0.0001.
Highest domain item correlations.

| Some women experience lack of or low sexual interest or desire in sex. | Over the past 4 weeks, how |
| Some women do not feel sexually turned on or do not have pleasurable sexual feelings when engaging in sexual activity. | Over the past 4 weeks, how |
