The aim of the study is to investigate the effectiveness of the abdominal breathing training on reducing anxiety. Using an experimental randomized controlled trial approach. The experimental group receiving abdominal breathing training, and control group without training. The effectiveness assessment used the Beck anxiety inventory, required to be completed by both the experimental group and control group. This study performed the pre-and-post assessments. This study performed the pre-test before the implementation of abdominal breathing training, and performed the post-test at Week 4 and Week 8 the end of abdominal breathing training. During this period, they received the abdominal breathing training at the outpatient clinic (every day 30 minutes, can include every time during the day). When the subjects were at home, they received self-training using the abdominal breathing training video (once every day and 30 minutes every time).
The research purpose is to investigate the effectiveness of abdominal breathing training on reducing anxiety. This study is an experimental research design. Using a randomized controlled trial approach. The patients receiving the intervention of abdominal breathing training were in the experimental group, while those who did not receive it were in the control group.
