Predictors of Sexual Functioning in a Sample of U.S. Marines: An 11-Year Follow-Up Study

Abstract

ABSTRACT We examined predictors of sexual functioning in male and female U.S. Marines (n = 589) assessed longitudinally for approximately 11 years. Multiple domains of sexual functioning (dysfunctional sexual behaviors, sexual frequency, sexual problems, and sexual satisfaction) were assessed at the 11-year follow-up assessment (T5). T5 depressive symptoms emerged as the most robust predictor of all domains of sexual functioning. Different patterns of correlates were associated with the different domains of sexual functioning—a finding that highlights the importance of considering the multidimensional nature of human sexuality. In addition, several significant gender × predictor interactions indicated differential relationships between predictors and sexual functioning outcomes for men and women. In particular, concurrent physical health and mental health were more strongly related to sexual functioning for women compared with men. We discuss how findings of the current study can contribute to the development of theories that can better capture the complexity of human sexuality, and we suggest ways that the current findings can inform mental health practitioners working with veterans and military personnel.
