Development and Initial Validation of the PROMIS(®) Sexual Function and Satisfaction Measures Version 2.0.

Area of Science:

• Sexual health research
• Psychometrics
• Patient-reported outcomes

Background:

• The PROMIS Sexual Function and Satisfaction measure (SexFS) v1.0 was developed for cancer patients.
• There is a need for expanded validity evidence in diverse populations.

Purpose of the Study:

• To develop the SexFS v2.0.
• To provide preliminary evidence of its validity in a broad population sample.

Main Methods:

• Built upon SexFS v1.0, incorporating expert review, patient focus groups (diverse conditions/identities), cognitive interviews, and psychometric evaluation.
• Evaluated psychometric properties in 2281 men and 1686 women, including an oversample for specific sexual problems.
• Examined differential item functioning (DIF) by gender and sexual activity, alongside convergent and known-groups validity.

Main Results:

• SexFS v2.0 includes 11 scored scales and 6 nonscored item pools, with improved domains from v1.0.
• Identified and addressed significant DIF in interest, orgasm, and satisfaction domains across gender and sexual activity.
• Convergent and known-groups validity were supported, with identified item subsets providing consistent measurement.

Conclusions:

• SexFS v2.0 offers enhancements over v1.0, including expanded validity, normative scores for sexually active adults, and new domains.
• The measure is applicable to men and women, sexually active with or without a partner.
• SexFS v2.0 is customizable, allowing users to select relevant domains and items for their specific research needs.
