The present study aimed to determine the predictors of drug use among students based on the Extended Prototype willingness model (EPWM).
This cross-sectional study was performed at Hamadan universities. The participants were selected via multi-stage sampling. Finally, out of 721 students participated. The questionnaire consisted of four sections: (a) socio-demographic characteristics, (b) Questionnaire about the prototype willingness model constructs, (c) Questionnaire about the status of drug use behavior, (d) Substance Abuse Media Literacy (SAML) scale. Data were analyzed using a structural equations partial least squares confirmatory composite approach and SPSS-23.
The mean age of students was of 23.47 ± 4.14 years. Based on results, behavioral willingness (β = 0.420, t-value = 9.010, p < 0.001) and behavioral intention (β = 0.291, t-value = 6.957, p < 0.001) significantly predicted drug use. The presented results of analysis, 66% of the variance of the drug use, 62% of the variable of the behavioral willingness, and 56% of the behavioral intention could be explained by the EPWM.
The present study demonstrated that EPWM could predict drug use in students. Therefore, designing and implementing educational and promotional intervention programs to reduce behavioral willingness and increase students' skills in substance abuse media literacy is necessary to prevent drug use behavior.
本研究旨在根据扩展原型意愿模型（EPWM）确定学生药物使用的预测因素。
这是一项横断面研究，在哈马丹大学进行。参与者通过多阶段抽样选择。最终，有 721 名学生参与。问卷包括四个部分：（a）社会人口统计学特征，（b）原型意愿模型结构问卷，（c）药物使用行为状况问卷，（d）物质滥用媒体素养（SAML）量表。使用结构方程偏最小二乘验证综合方法和 SPSS-23 对数据进行分析。
学生的平均年龄为 23.47±4.14 岁。结果表明，行为意愿（β=0.420，t 值=9.010，p<0.001）和行为意向（β=0.291，t 值=6.957，p<0.001）显著预测药物使用。分析结果显示，66%的药物使用方差、62%的行为意愿变量和 56%的行为意向可以用 EPWM 来解释。
本研究表明，EPWM 可以预测学生的药物使用。因此，设计和实施教育和宣传干预计划，以降低行为意愿和提高学生的物质滥用媒体素养技能，对于预防药物使用行为是必要的。
