Drug addiction is a global social and health issue, with children being the most vulnerable group. This study aimed to validate the Addiction Potential Questionnaire for Iranian children aged 12 to 18 years using confirmatory factor analysis (CFA) and structural equation modeling (SEM).
This cross-sectional study was conducted in 2023 on 600 students from Shiraz, Iran, using multi-stage sampling (stratified-cluster-simple random sampling). The Addiction Potential Questionnaire used in this study was originally developed by the research team to assess addiction potential among Iranian children. Construct validity was assessed through CFA, along with convergent and discriminant validity, and SEM. The reliability of the tool was calculated using Cronbach's alpha, intra-class correlation coefficient, and composite reliability.
Results from CFA indicated a χ/df ratio of 2.80. Additional fit indices also confirmed a good fit for the final model, including goodness-of-fit index (GFI=0.9), parsimonious comparative fit index (PCFI=0.74), and comparative fit index (CFI=0.8). Assessing convergent and discriminant validity revealed that all dimensions met acceptable standards. SEM results showed strong positive relationships among latent variables, with correlations of 0.82 between environmental-social-spiritual (ESS) and physical-psychological, and 0.98 between ESS and Other (<0.001). The reliability indices for each factor were as follows: Other: Cronbach's alpha (α)=0.46, Omega (composite reliability, CR)=0.43, Maximal reliability (Max(R))=0.44, intraclass correlation coefficient (ICC) [95% confidence interval (CI)]=0.74 (0.64-0.81), Akaike information criterion (AIC)=0.12. Family: α=0.70, CR=0.72, Max(R)=0.73, ICC [95% CI]=0.72 (0.61-0.79), AIC=0.24. Physical-psychological: α=0.80, CR=0.82, Max(R)=0.83, ICC [95% CI]=0.84 (0.78-0.88), AIC=0.35. ESS: α=0.61, CR=0.60, Max(R)=0.66, ICC [95% CI]=0.69 (0.58-0.78), AIC=0.13. Total Questionnaire: α=0.89, CR=0.85, Max(R)=0.86, ICC [95% CI]=0.88 (0.83-0.91), AIC=0.39.
The results indicated that the tool possesses good validity and reliability, making it a credible instrument for assessing addiction potential in Iranian children and for developing preventive programs.
药物成瘾是一个全球性的社会和健康问题，儿童是最脆弱的群体。本研究旨在通过验证性因素分析（CFA）和结构方程模型（SEM）来验证针对12至18岁伊朗儿童的成瘾潜力问卷。
本横断面研究于2023年对来自伊朗设拉子的600名学生进行，采用多阶段抽样（分层整群简单随机抽样）。本研究中使用的成瘾潜力问卷最初由研究团队开发，用于评估伊朗儿童的成瘾潜力。通过CFA评估结构效度，同时评估收敛效度和区分效度以及SEM。使用克朗巴哈α系数、组内相关系数和组合信度来计算该工具的信度。
CFA结果表明χ/df比率为2.80。其他拟合指数也证实最终模型拟合良好，包括拟合优度指数（GFI = 0.9）、简约比较拟合指数（PCFI = 0.74）和比较拟合指数（CFI = 0.8）。评估收敛效度和区分效度表明所有维度均符合可接受标准。SEM结果显示潜在变量之间存在强正相关关系，环境 - 社会 - 精神（ESS）与身体 - 心理之间的相关性为0.82，ESS与其他因素之间的相关性为0.98（<0.001）。每个因素的信度指标如下：其他因素：克朗巴哈α系数（α）= 0.46，欧米伽（组合信度，CR）= 0.43，最大信度（Max(R)）= 0.44，组内相关系数（ICC）[95%置信区间（CI）]= 0.74（0.64 - 0.81），赤池信息准则（AIC）= 0.12。家庭因素：α = 0.70，CR = 0.72，Max(R)= 0.73，ICC [95% CI]= 0.72（0.61 - 0.79），AIC = 0.24。身体 - 心理因素：α = 0.80，CR = 0.82，Max(R)= 0.83，ICC [95% CI]= 0.84（0.78 - 0.88），AIC = 0.35。ESS因素：α = 0.61，CR = 0.60，Max(R)= 0.66，ICC [95% CI]= 0.69（0.58 - 0.78），AIC = 0.13。问卷总分：α = 0.89，CR = 0.85，Max(R)= 0.86，ICC [95% CI]= 0.88（0.83 - 0.91），AIC = 0.39。
结果表明该工具具有良好的效度和信度，使其成为评估伊朗儿童成瘾潜力和制定预防计划的可靠工具。
