Abstract
A German version of the Sexual Behaviour Questionnaire (SBQ-G) is a short self-rating instrument covering the four domains of sexual function using colloquial words. Frequency of sexual dysfunction was counted and chance-corrected retest reliability was calculated. Eleven women and 12 men participated. Reception of the SBQ-G was favourable and more females than males reported at least moderate sexual dysfunction. Sexual arousal and ability to enjoy sex showed the lowest retest stability. The SBQ-G is a recommendable clinical instrument with high practicability and satisfactory retest reliability. However, gender differences and a high variability of sexual functioning in healthy subjects should be kept in mind.
