The goal of this clinical trial is to learn whether motivational interviewing helps smokers with acute coronary syndrome (heart attack or unstable angina) quit smoking. It also looks at whether motivational interviewing changes patients' self-efficacy, anxiety, views about the pros and cons of smoking, and nicotine dependence.
The main question it aims to answer is: Does motivational interviewing increase the rate of quitting smoking at 6 months compared with routine follow-up?
Researchers compared patients who received motivational interviewing with patients who received routine outpatient follow-up only.
Participants in the intervention group received a face-to-face motivational interviewing session at the first visit and a telephone session at 3 months. Participants in both groups completed questionnaires at the first visit, at 3 months and at 6 months.
This single-center, randomized controlled trial was conducted at the cardiology outpatient clinic of Trakya University Hospital, Edirne, Türkiye, between April 2017 and May 2018 as part of a doctoral thesis at the Trakya University Institute of Health Sciences, Department of Nursing.
Smoking patients aged 18 years or older with a diagnosis of acute coronary syndrome were randomized to an intervention group or a control group using simple randomization (Research Randomizer). Participants were not informed of their group allocation.
Intervention group: Motivational interviewing sessions of approximately 15-20 minutes were delivered by a researcher trained in motivational interviewing, face-to-face at baseline and by telephone at the 3rd month, in accordance with the principles described by Miller and Rollnick.
Control group: Participants received routine outpatient follow-up and completed only the data collection instruments at the same time points.
Data were collected at baseline, 3 months and 6 months using a Patient Information Form, the Self-Efficacy Scale, the Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A), the Decisional Balance Scale and the Fagerström Test for Nicotine Dependence. Smoking cessation was based on self-report.
The trial was registered retrospectively after study completion.

Exclusion Criteria:
Psychiatric disorder
* Communication difficulties
Participants received a face-to-face motivational interviewing session (approximately 15-20 minutes) at baseline and a telephone motivational interviewing session (approximately 15-20 minutes) at the 3rd month, in addition to routine outpatient follow-up. Data collection instruments were administered at baseline, 3 months and 6 months.
Behavioral: Motivational Interviewing
Participants received routine outpatient follow-up only and completed the data collection instruments at baseline, 3 months and 6 months. No motivational interviewing was performed.
Client-centered counseling based on the principles described by Miller and Rollnick, delivered by a researcher trained in motivational interviewing. Sessions lasted approximately 15-20 minutes and were conducted face-to-face at baseline and by telephone at the 3rd month, focusing on exploring ambivalence about smoking and strengthening motivation to quit.
Smoking Cessation Rate
Proportion of participants who reported not smoking at the 6th-month interview (self-reported; not biochemically verified).
Time frame: 6 months
Self-Efficacy Score
Self-Efficacy Scale (23 items; total score range 23-115; higher scores indicate greater perceived self-efficacy), including four sub-dimensions: willingness to initiate behavior, willingness to maintain behavior, completing the behavior and struggling with obstacles.
Time frame: Baseline, 3 months and 6 months
Anxiety Score
Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A; score range 0-21; higher scores indicate greater anxiety).
Time frame: Baseline, 3 months and 6 months
Decisional Balance Score
Decisional Balance Scale with two sub-dimensions, perceived pros and perceived cons of smoking (each score range 12-60).
Time frame: Baseline, 3 months and 6 months
Nicotine Dependence Score
Fagerström Test for Nicotine Dependence (FTND; score range 0-10; higher scores indicate greater nicotine dependence).
Time frame: Baseline, 3 months and 6 months

Ran from Apr 2017 to primary completion in May 2018, 13 months.
Of 212 non-industry interventional studies with no phase under Acute Coronary Syndrome, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 46. This study's 13 months is below that.
Counting every sponsor, half of 227 studies reached it within 34 months; a quarter within 17 and three quarters within 46.
