In 1991 the Gallup Organization performed a nationwide demographic study to determine the attitudes, opinions, and behaviors of both users and nonusers of chiropractic services.
Overall, 90% felt that chiropractic health care was effective: more than 80% were satisfied with the treatment they received; nearly 75% felt that most of their expectations were met during the last visit or series of visits; 68% said they would likely see a doctor of chiropractic again for treatment of a similar condition, and 50% would likely be willing to see a doctor of chiropractic for some other problem chiropractors treat. Nearly 80% of the chiropractic users felt that the cost of chiropractic treatment was reasonable.
