Sexual Desire Scale (SDI-2)
Sexual desire measured across two separate dimensions

What Is the Sexual Desire Inventory-2 (SDI-2)?
The SDI-2 assesses sexual desire across two distinct dimensions: dyadic (partner-focused) and solitary (self-focused) desire. Spector, Carey & Steinberg developed this 14-item measure in 1996.
Two Dimensions
1. Dyadic Sexual Desire (9 items): Interest in or desire for sexual activity with a partner — including initiation, receptivity, and preferred frequency 2. Solitary Sexual Desire (5 items): Interest in engaging in sexual behavior by oneself, including masturbation and sexual fantasy
Scoring
Items use various response scales. Dyadic desire items include both frequency and intensity ratings. Solitary desire items focus on frequency and strength of desire. Each dimension produces a separate score.
