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-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.
研究记录了 237 个进行性行为的不同原因,并将其聚类为 141 项 13 分量表的 YSEX?工具。尽管 YSEX?具有令人印象深刻的心理测量特性,但所需的完成时间是其在时间受限的情况下使用的障碍。本研究开发并验证了该工具的简短版本。新的 28 项 14 分量表 YSEX?-SF 表现出可接受的模型拟合度和良好的内部可靠性,具有跨形式和构念效度的证据。YSEX?-SF 保持了原始工具的良好心理测量特性,完成时间明显缩短,这可能有助于研究性动机。
