       This quasi-experimental research study aimed to investigate the effects of a program of inhaler application with knowledge related to health behavior on Perceived Self-Efficacy and health behavior in patients with asthma. A purposive sampling technique was used to recruit  of 56 patients diagnosed with asthma from an out-patient clinic of a primary care unit in Bangkok. The sample was divided into two groups. The experimental group consisted of 28 asthma patients while the control group consisted of another 28 patients. The experimental group received the program of inhaler application along with knowledge related to perceived self-efficacy and health behavior while the control group received the usual care for asthma.  The questionnaire consisted of demographic information, self-efficacy scale or SES (CVI=.8; alpha=.85) for asthma, and health practice scale or HPS (CVI=.9; alpha=.88). The data were obtained during three phases, including before receiving the program,  immediately after finishing the program, and 4 weeks after completion of the program. The data were analysed using descriptive statistics, Chi-square, One-way repeated measure ANOVA, and independent-t test.

        The results showed that the average scores of SES and HPS in the experimental group were significantly higher than those of the control group when receiving the program immediately after completion, and 4 weeks after completion (p<.01).  The average scores of SES and HPS in the experimental group when receiving the program immediately after completion and 4 weeks after completion, were significantly higher than those of the group before receiving the program (p<.01). This study suggests that nurses should promote and apply SES and HPS program in order to assist patients in achieving a good quality of life. This sutudy suggests that nurses should promote this programe to assist patients with appropriate health behaviors . As a result, good asthma control.
