*2.3. Analysis Items*

The analysis items included in this study were the participants who answered 'Yes' to the question asking whether they had a child under the age of 19, during the TKM usage survey in 2017, as well as the questions regarding the satisfaction and awareness of their children. Additionally, based on the children's TKM use reported by parents, the relationships between the demographics, the experience of using TKM, their opinion on the use of TKM, and the perception of treatment effects on sixteen diseases, were analyzed. The demographics of the participants (mother or father) were used to examine the relationship between the answers about the children and the characteristics of participants. The answers about the children included the children's experience with TKM, the reason why their children used TKM, the kind of TKM treatment the children experienced, the degree of satisfaction with their children's TKM experience, and cause of dissatisfaction with using TKM. The basic demographic information of the participants included their sex, age group, area of residence, education, employment status, household income, type of healthcare coverage, and subscription status of private medical insurance. The experience of using TKM variables included TKM participation, the reason for choosing to use TKM, participants' experience with TKM, participants' satisfaction with TKM, participants' awareness of TKM, money invested to use TKM, their willingness to use TKM again in the future, and their willingness to recommend TKM to others. Regarding the perception of treatment effects on diseases, variables were used following sixteen diseases: (1) disc related disease (herniation of intervertebral disc, spinal stenosis); (2) osteoarthritis; (3) frozen shoulder shoulder pain;

(4) back pain; (5) sprain; (6) facial nerve paralysis; (7) stroke; (8) hypertension; (9) diabetes mellitus; (10) digestive disease; (11) common cold rhinitis; (12) dementia (13) cancer related pain; (14) infertility; (15) skin disease (atopic dermatitis); (16) genitourinary disease. Also, whether the characteristics of the participants (demographics, their opinion or ideas on TKM, etc.) had an impact on the children's use of TKM and the possible strategies to promote use of TKM in different target groups, were explored.
