Purpose: Although the interest in Complementary and Alternative Therapies (CAT) has increased in recent years, the level of knowledge on this subject is unsettled. The opinions of future health professionals on this subject are very important. For this reason, the present study was carried out in order to examine the knowledge, attitude, and beliefs of health science students on CATs. Methods: The present study involved 821 students (mean age 20.68±0.43 years) from Physiotherapy and Rehabilitation, Nursing, and Midwifery disciplines. The CAT Survey, which was prepared by reviewing the literature, was conducted after recording the demographic data of participants. Results: It was determined that 28% of participants had knowledge about CATs and 92% believed in efficiency of CAT practices. The sources of information were environment (49%) and internet (29%) and it was found that 76% of participants want the CAT methods to be involved in curricula. The participants stated that diet (32.5%) and massage (32.5%) were the most effective methods. Examining the use of CAT methods, it was found that 52.4% has used massage, 40.8% used herbal therapy, 40.2% used SPA, and 38.7% used diet. Examining the benefits obtained, the results were found to be 42% for massage, 30% for herbal therapy, and 26% for SPA. Conclusion: It was determined that health science students have positive attitude and knowledge about diet and massage at most while there is a lack of knowledge on other CAT approaches although they have positive attitudes and beliefs. Examining the sources of information, it is thought that adding the CAT methods into curricula of health sciences would be useful in increasing the level of knowledge and preventing malpractices.
