Examined a version of the Substance Abuse and Mental Health Services Administration (SAMHSA) wellness model that was revised to include a ninth factor, sexual wellness: "understanding the human body, choosing the type and size of one's family, and experiencing satisfaction (alone or with consenting others) while maintaining autonomy, minimizing exposure to disease, and preserving safety." As expected, in a study of 216 college students, sexual wellness was found to be a memorable and valued factor--contributing incrementally to the model and bearing expected relationships with overall wellness, sexual satisfaction, mental health, and relevant psychosocial variables. Neglect of sexual wellness is liable to unduly limit SAMHSA's efforts to enhance outcomes for persons with mental illness and substance use disorders.
