Callahan LF et al. - Fifteen percent of the sample used one or more CAM providers. Medical skepticism was positively associated with CAM provider use. A one point increase in skepticism increased the probability of CAM provider use by approximately 70%. Individuals, who were younger, had better perceived health, and had a diagnosis of osteoarthritis or fibromyalgia had greater skepticism. By knowing more about medical skepticism and other determinants of CAM provider use, conventional practitioners can target patients to improve their uptake of appropriate conventional care, while also monitoring patients alternative therapy use.
