One primary health issue that has significantly impacted a portion of society's youth is smoking. This study evaluates the influence of the theory of planned behavior (TPB) on male high school students' decision-making regarding smoking. This experimental study was conducted in 2022 on 300 teenage students in Jahrom, Iran (150 individuals in the experimental group and 150 in the control group). The data collection instrument included demographic information, knowledge, and TPB-related questions (attitude, subjective norms, perceived behavioral control, behavioral intention, and smoking prevention behavior). Questionnaires were completed by both groups before and after the conclusion of the program. The experimental group participated in five 60-min training sessions. Data analysis was performed using SPSS 25, employing descriptive tests such as the independent -test, paired -test, and chi-square test ( < 0.05). Prior to education, no distinction was witnessed in the components of the TPB between the groups ( > 0.05). Postintervention, the intervention group exhibited an increase in knowledge scores from 10.89 ± 1.21 to 13.49 ± 1.64, attitude scores from 33.85 ± 1.23 to 51.69 ± 4.69, subjective norms from 4.52 ± 1.81 to 6.38 ± 1.86, perceived behavioral control from 18.38 ± 3.32 to 31.13 ± 1.54, behavioral intention from 6.93 ± 2.75 to 8.33 ± 2.87, and behavior from 6.75 ± 2.74 to 8.53 ± 2.68 ( < 0.001). This study showed the impact of the TPB-based education on smoking avoidance behavior. Consequently, the program designed to avoid smoking can make advantage of this notion.
吸烟是一个对部分社会青年产生重大影响的主要健康问题。本研究评估计划行为理论（TPB）对男性高中生吸烟决策的影响。这项实验研究于2022年在伊朗贾赫罗姆的300名青少年学生中进行（实验组150人，对照组150人）。数据收集工具包括人口统计学信息、知识以及与TPB相关的问题（态度、主观规范、感知行为控制、行为意图和吸烟预防行为）。两组在项目结束前后都完成了问卷调查。实验组参加了五次60分钟的培训课程。使用SPSS 25进行数据分析，采用独立检验、配对检验和卡方检验等描述性检验（<0.05）。教育前，两组在TPB各成分上无差异（>0.05）。干预后，干预组的知识得分从10.89±1.21提高到13.49±1.64，态度得分从33.85±1.23提高到51.69±4.69，主观规范从4.52±1.81提高到6.38±1.86，感知行为控制从18.38±3.32提高到31.13±1.54，行为意图从6.93±2.75提高到8.33±2.87，行为从6.75±2.74提高到8.53±2.68（<0.001）。本研究显示了基于TPB的教育对避免吸烟行为的影响。因此，旨在避免吸烟的项目可以利用这一理念。
