The Why Have Sex Short-Form Questionnaire (YSEX?-SF)

Meston, C. M., Kilimnik, C. D., Freihart, B. K., & Buss, D.M

Although the YSEX? has impressive psychometric properties, the required completion time is a barrier to its use in time-constrained contexts. We developed and validated a short-form version of the instrument. The new 28-item, 14 subscale YSEX?-SF demonstrates acceptable model fit and good internal-reliability, with evidence for cross-form and construct validity. The YSEX?-SF maintains the original instrument’s sound psychometric properties with a significantly shorter completion time, which may facilitate the study of sexual motivation.
