Brief Summary

Smoking is one of the leading preventable public health problems worldwide, particularly among young adults who are at increased risk of nicotine dependence. Nursing students represent an important target population because, as future health professionals, they are expected to play a significant role in tobacco control and smoking cessation counseling. The Transtheoretical Model (TTM) is one of the most widely used theoretical frameworks for promoting health behavior change. The aim of this study will be to determine the effect of Transtheoretical Model-based motivational interviewing on changing smoking behavior among nursing students. This study will be planned as a single-group, quasi-experimental pretest-posttest intervention. Nursing students who smoke cigarettes and voluntarily agree to participate will be included in the study. At baseline, participants will complete a Demographic Information Form, the Fagerström Test for Nicotine Dependence, the Stages of Change questionnaire, the Self-Efficacy/Temptation Scale, the Processes of Change Scale, and the Decisional Balance Scale. Participants will receive Transtheoretical Model-based educational sessions and motivational interviewing interventions focusing on the health effects of smoking, reasons for smoking, the benefits of smoking cessation, identification of social support resources, relapse prevention strategies, and successful smoking cessation experiences. The Stages of Change questionnaire will be administered before each motivational interviewing session, and all outcome measures will be reassessed during follow-up evaluations. The study is expected to provide evidence regarding the effectiveness of Transtheoretical Model-based motivational interviewing in reducing smoking behavior, decreasing nicotine dependence, promoting progression through the stages of change, improving self-efficacy, enhancing the use of behavioral change processes, and supporting smoking cessation among nursing students.

Outcome Measures

Primary Outcomes (1)

• Change in Smoking Behavior

  The primary outcome is the change in smoking behavior following the Transtheoretical Model-based motivational interviewing intervention. Smoking behavior will be evaluated by the average number of cigarettes smoked per day and smoking cessation status.

  Baseline, Mid-intervention Assessment (1 month), Post-intervention Assessment (2 months)

Secondary Outcomes (4)

• Change in Nicotine Dependence

  Baseline, Mid-intervention Assessment (1 month later), Post-intervention Assessment (2 months later)

• Change in Processes of Change

  Baseline, Mid-intervention Assessment( 1 month later), Post-intervention Assessment (2 months later)

• Change in Self-Efficacy/Temptation for Smoking Cessation

  Baseline, Mid-intervention Assessment (1 month later), Post-intervention Assessment (2 months later)

• Change in Decisional Balance

  Baseline, Mid-intervention Assessment (1 month later), Post-intervention Assessment (2 months later)

Study Arms (1)

Motivational Interviewing

EXPERIMENTAL

Participants will receive a Transtheoretical Model-based motivational interviewing intervention designed to promote smoking behavior change and smoking cessation. The intervention will consist of structured face-to-face motivational interviewing sessions delivered in groups, supported by educational content on the health effects of smoking, benefits of smoking cessation, behavior change strategies, social support, relapse prevention, and self-efficacy enhancement. Outcomes will be evaluated using validated questionnaires administered at baseline and follow-up assessments.

Behavioral: Transtheoretical Model-Based Motivational Interviewing

Interventions

Transtheoretical Model-Based Motivational Interviewing BEHAVIORAL

Participants will receive a Transtheoretical Model-based motivational interviewing intervention to promote smoking behavior change and smoking cessation. Face-to-face motivational interviewing sessions will be conducted by a researcher trained in motivational interviewing. According to the intervention protocol, participants may receive between two and six sessions depending on their readiness to change, individual needs, and continued participation throughout the study. The intervention will include counseling and education on smoking-related health risks, smoking cessation, motivation enhancement, self-efficacy, behavior change strategies, social support, and relapse prevention. Participants' stage of change will be assessed before each session, and the intervention will be tailored accordingly. Outcomes will be evaluated using validated instruments measuring smoking behavior, nicotine dependence, stages of change, self-efficacy, and behavior change processes.
