Notes: PROMIS items have a 30-day recall period (i.e., each question starts with “In the past 30 days…”).

PCSI items have a 4-week recall period (i.e., each question starts with “In the past 4 weeks…”).

PCSI Erectile Function is derived from the Sexual Dysfunction subscale (Clark, 2005).

PCSI MOS Sexual Problems is missing two items from its original subscale (Clark, 2005).

^┼Items from PROMIS SexFS-V1 (Flynn et al., 2013). The five underlined items are worded slightly differently than in PROMIS SexFS-V1.

^╪Items from PROMIS SexFS-V2 (Weinfurt et al., 2015).

^§Items in PROMIS SexFS-Preferred (best-fitting items in the current study; see Table 3 for model and item fit).
