The Effect of an Anti-Smoking Mobile Application on Self-Efficacy, Decision Making and Breath Carbon Monoxide Levels

Purpose:This research aims to examine the effect of a mobile application developed against smoking behavior on teachers' self-efficacy, decision-making and carbon monoxide levels in breath.The research was planned as a randomized controlled experimental type.Working in public schools in Izmir/Narlıdere District teachers constitute the universe of the research. According to the calculations made, it was decided to include 35 people in the experimental group and 35 people in the control group. After obtaining institutional permissions, teachers who meet the inclusion criteria will be determined.To ensure homogeneity, control and intervention groups will be stratified according to age, gender, and addiction levels.Assignment to intervention and control groups will be made by simple randomization method.The average scores of teachers' self-efficacy, breath carbon monoxide and decision-making levels are the dependent variables of the study.The status of using the mobile application is the independent variable. "Personal Information Form", "Fagerstrom Nicotine Dependency Test (FNBT)", "Self-Efficacy Scale", "Classification of Stages of Change Scale", "Decision Making Scale" and "Carbon Monoxide Measurement Values Tracking Form" will be used in this research. SPSS 26.0 Package program will be used to analyze the data in the study. It will be evaluated statistically at a 95% confidence interval and a significance level of p\<0.05. Number and percentage distributions for sociodemographic characteristics will be used in the analysis of the data.In comparisons between groups, parametric or nonparametric tests will be used after evaluating the normal distribution feature of the scale scores.

Hypotheses 1 H1:There is a difference between the breath CO level scores of intervention and control group teachers according to time (pre-test - 1st month, 3rd month and 6th month).

Hypotheses 2 H1:There is a difference between the self-efficacy scale scores of intervention and control group teachers according to time (pre-test, 1st month, 3rd month, 6th month).

Hypotheses 3 H1: There is a difference between the decision-making level scores of teachers in the intervention and control groups according to time (pretest-1st month, 3rd month and 6th month).
