Primary use / Purpose: 

The Sexual Desire Inventory- 2 (SDI-2) is a brief 14-item scale that aims to measure the multidimensional construct of sexual desire in a dyadic context. Four items are scored on an 8-item response scale from '0' (= 'not at all') to '7' (= 'more than once a day') concerning frequency of desire. The remaining items were answered on a 9-point Likert scale ranging from '0' (= 'no desire') to '8' (= 'strong desire'). Possible score range from 0 to 112.


The SDI-2 was created by Spector, Carey and Steinberg to develop a measure that quantified sexual desire in cognitive terms as opposed to previous measures that used predominantly behavioural methods.


Psychometric analysis is reported in Spector, Carey and Steinberg (1996).
