PMID: 16959664 To examine the predictive potential of relationship variables on sexual functioning in women with fibromyalgia, we instructed 63 women (age 21-54 years) to fill out several questionnaires. Low relationship satisfaction was the strongest and most-frequent predictor of problematic sexual functioning. In addition, more fatigue and-only after taking account of relationship satisfaction-more active engagement (i.e., involvement) of the spouse were associated with reduced sexual functioning and satisfaction. Our study suggests that for women with Fibromyalgia, relationship satisfaction is good for sexual functioning. Although having an involved spouse is good for the relationship, it may be bad for sexual functioning.
