A time-series perspective on effectiveness of a health teaching program on chronic obstructive pulmonary disease.

The purpose of this research was to study the long-term effects of attendance at "Help Yourself to Better Breathing" classes on knowledge attainment, coping strategies, and anxiety, depression, and hostility in individuals with chronic obstructive pulmonary disease. Data were gathered immediately and six months following completion of the program. The results were then compared to those obtained before program attendance. The data showed a significant difference between the pretest, immediate post-test, and the six-month knowledge scores. Coping scores remained the same, which may indicate that not enough emphasis is placed on the development of these skills. There was a significant lowering of the depression scores at the six-month post-testing, and anxiety and hostility scores were lower, but not significantly so. In addition, some participants after the classes were completed chose to enroll in the Better Breathers Program support group and in a pulmonary rehabilitation program. Overall, this study indicates that beneficial effects are evidenced six months following attendance at "Help Yourself to Better Breathing" classes.
