The aim of this
study was to analyze the reliability, factorial structure and validity indicators of the
Spanish version of the Index of Sexual Satisfaction (ISS). A total of 646 participants
filled in the ISS, Sexual Desire Inventory, Sexual Arousal Inventory, and Double Standard
Scale. Exploratory factorial analysis showed three factors which explained 45.56% of
total variance, nevertheless, this solution reflects a methodological artifact due to items
redaction. For this reason, original unifactorial structure of the scale was maintained,
which reaches an internal consistency reliability value equals .89. No statistically significant
differences between men and women were found on the total score, but were found on
11 items. Furthermore, sexual satisfaction positively correlates with dyadic sexual desire
and with sexual arousability, and negatively with sexual double standard. The Spanish
version of the Index of Sexual Satisfaction shows appropriate reliability and validity
indexes, nevertheless, more studies analyzing item 13, which was problematic on this
study, are needed.

Key words:

sexual satisfaction, sexual desire, sexual arousal, double standard.
