To evaluate the relationship between age at onset of cannabis use and cannabis abuse in a sample of Portuguese cannabis users, testing the mediating role of the number of friends using cannabis and comparing these relationships between male and female subsets.
A sample of 529 Portuguese cannabis users comprising 276 males and 244 females aged from 14 to 21 years completed a sociodemographic questionnaire, the Cannabis Abuse Screening Test (CAST), and answered four questions related to cannabis use. Data were analyzed using the PROCESS macro in SPSS version 26.0.
Age at onset of cannabis use was negatively related to the number of friends using cannabis, while the number of friends using cannabis had a positive relationship with cannabis abuse. As predicted, the number of friends using cannabis seems to have a mediating role in the relationship between cannabis onset age use and cannabis abuse, since the indirect effect was found to be significant. The pattern of the relationships among the variables observed was found to be similar for both male and female subsets of the sample. However, males reported higher cannabis abuse than females.
The results highlight the mediating role of friends' use of cannabis in the relationship between age at onset of cannabis use and users' abuse. These results highlight the importance of early intervention in cannabis use. In particular, the pattern of the relationships observed among the studied variables emphasizes the need to monitor and conduct peer training interventions or interventions to promote of social skills.
在葡萄牙大麻使用者样本中评估大麻使用起始年龄与大麻滥用之间的关系，检验朋友使用大麻数量的中介作用，并比较男性和女性亚组之间的这些关系。
一个由 529 名年龄在 14 至 21 岁之间的葡萄牙大麻使用者组成的样本，包括 276 名男性和 244 名女性，完成了一份社会人口学问卷、大麻滥用筛查测试（CAST），并回答了四个与大麻使用相关的问题。数据使用 SPSS 版本 26.0 中的 PROCESS 宏进行分析。
大麻使用起始年龄与使用大麻的朋友数量呈负相关，而使用大麻的朋友数量与大麻滥用呈正相关。正如预测的那样，朋友使用大麻的数量似乎在大麻使用起始年龄与大麻滥用之间的关系中具有中介作用，因为发现间接效应具有统计学意义。在所观察到的变量之间的关系模式在样本的男性和女性亚组中是相似的。然而，男性报告的大麻滥用程度高于女性。
研究结果强调了朋友使用大麻在大麻使用起始年龄与使用者滥用之间关系中的中介作用。这些结果强调了早期干预大麻使用的重要性。特别是，观察到的研究变量之间关系的模式强调了需要监测和进行同伴培训干预或促进社交技能的干预。
