eDiary and Female Sexual Distress Scale(©) in evaluating distress in hypoactive sexual desire disorder (HSDD)

Sex-related distress is integral to the diagnosis of hypoactive sexual desire disorder (HSDD). This article describes the results of three prospective, non-treatment validation studies (two North American and one European), each testing over 200 participants with HSDD, other types of female sexual dysfunction (FSD), or no FSD in which the 12-item Female Sexual Distress Scale(©) (FSDS(©)), the 13-item FSDS-Revised(©)(FSDS-R(©)), and a single question asked using a daily electronic diary (the eDiary For HSDD Trials(©); eDiary) were used to measure sex-related distress. FSDS results with 30- and seven-day recall were equivalent. The results observed with FSDS-R Item 13 (a single question assessing concern due to low sexual desire) were comparable to the FSDS. Mean eDiary monthly distress scores were closer to the minimum possible score (equivalent to "a little bit" of distress) and were about twice as variable as FSDS or FSDS-R Item 13 scores in participants with HSDD. All three measures confirmed that there is more distress in women with HSDD compared to women with no sexual dysfunction at all time points, demonstrating discriminant validity.
