Reliability and validity of the Sexual Interest and Desire Inventory-Female (SIDI-F), a scale designed to measure severity of female hypoactive sexual desire disorder.
The Sexual Interest and Desire Inventory-Female (SIDI-F) is a 13-item scale developed as a clinician-administered assessment tool to quantify the severity of symptoms in women diagnosed with hypoactive sexual desire disorder (HSDD). The present investigation assessed the reliability and validity of the SIDI-F as a measure of HSDD severity. Results show that the SIDI-F exhibits excellent internal consistency, with Cronbach's alpha of 0.9. The validity of the SIDI-F as a measure of HSDD severity was confirmed by a number of observations. Women with a clinical diagnosis (Diagnostic and Statistical Manual of Mental Disorders [DSM-IV-TR; American Psychiatric Association, 2000]) of HSDD had significantly lower SIDI-F scores than women not meeting diagnostic criteria for any subtype of female sexual dysfunction and women diagnosed with female orgasmic disorder. There was a high correlation between scores on the SIDI-F and scores on the Female Sexual Function Index (FSFI; Rosen et al., 2000) and an interactive voice response version of the Changes in Sexual Functioning Questionnaire (CSFQ; Clayton, McGarvey, & Clavet, 1997; Clayton, McGarvey, Clavet, & Piazza, 1997), two validated measures that assess general female sexual dysfunction. In contrast, there was a poor correlation between SIDI-F scores and scores on a slightly modified Marital Adjustment Scale (Locke, Wallace, 1959; MAS), an assessment of general (nonsexual) relationship satisfaction. Taken together, the results of the present investigation indicate that the SIDI-F is a reliable and valid measure of HSDD severity, independent of relationship issues.
