Abstract Research has documented 237 distinct reasons for engaging in sex, which have been clustered into the 141-item, 13 subscale YSEX? instrument. Although the YSEX? has impressive psychometric properties, the required completion time is a barrier to its use in time-constrained contexts. The current studies develop and validate 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…

On the sins of short-form development.

This "Mini-Marker" subset demonstrated unusually impressive features for an abbreviated inventory, consisting of five scales that show, in comparison to the original scales, less use of difficult items, lower interscale correlations, and somewhat higher mean inter-item correlations; alpha reliabilities are somewhat lower.
Beyond global sociosexual orientations: a more differentiated look at sociosexuality and its effects on courtship and romantic relationships.
3 theoretically meaningful components of sociosexuality are established: past behavioral experiences, the attitude toward uncommitted sex, and soci homosexual desire (all measured by a revised version of the Sociosexual Orientation Inventory): within couples, the 3 components showed distinct degrees of assortative mating and distinct effects on the romantic partner.

Response burden and questionnaire length: is shorter better? A review and meta-analysis.
Given the inherently problematic nature of comparing questionnaires of various lengths, it is preferable to base decisions on use of instruments on the content rather than the length per se.
Test length and validity revisited
Results from three different subject samples extend earlier findings that lengthening a scale beyond some point can actually weaken its validity. A near‐optimal algorithm selected the most valid
