The effectiveness of the Motivational Interviewing (MI) program for smokers at the Phutei Sub-District Health Promotion Hospital, Phutei Sub-District, Wichian Buri District, Phetchabun Province

Abstract

This experimental research aims to compare the knowledge, attitudes, and practices of smokers before the implementation of a program between the experimental group and the control group. It also seeks to compare the knowledge, attitudes, and practices of smokers before and after the trial of the program in the experimental group, as well as to compare the knowledge, attitudes, and practices of smokers after the trial of the program between the experimental group and the control group.
The sample group consisted of 60 smokers, selected through a case selection method that aligned closely with the research objectives, more than usual. They were randomly assigned to an experimental group of 30 people and a control group of 30 people using simple random sampling. The tools used for data collection included an interview questionnaire, which comprised a knowledge assessment, an attitude assessment, and a behavior assessment for smokers, as well as an interview record to create motivation. These tools were validated for content quality by three experts and reliability was measured using the Kuder-Richardson method (KR-20) and Cronbach's alpha. Descriptive statistics were used, and the Wilcoxon W test was applied to analyze the mean scores within the experimental group, while the MannWhitney U test was used to compare the mean scores between groups.
The study results of the motivational interviewing program for smokers found that before the use of the program, there were no significant differences in the average scores of knowledge, attitudes, and practices between the experimental group and the control group (p>0.05). After using the program, the experimental group showed a statistically significant increase in average scores for knowledge, attitudes, and practices (p<0.05). Furthermore, after the trial of the program, the average scores for knowledge, attitudes, and practices in the experimental group were significantly higher than those in the control group (p<0.05). The results of this study show that the motivational interviewing program for smokers is effective and can be used in counseling to help smokers quit smoking.
