Methamphetamine is a synthetic psychostimulant that is showing a rising trend of usage among adolescents and youths. Its harmful side effects and high risk of developing addiction is a public health problem. Recognizing the knowledge, attitudes, and practices (KAP) on methamphetamine is critical in the planning of an intervention strategy. Currently there is a lack of KAP questionnaires on methamphetamine. The study aims to develop and validate a KAP questionnaire on methamphetamine-use for use among Malaysian adolescents. Following an extensive literature review, face and content validity were carried out among healthcare workers, the public, students, and local subject matter experts. A pilot study was conducted amongst 50 students to assess the test-retest reliability. The questionnaire was then distributed to two groups of 269 and 331 individuals for the Exploratory (EFA) and Confirmatory Factor Analysis (CFA), respectively. The internal reliability was also assessed among these groups. The content validation consisting of Item Content Validity Index (I-CVI, ranging from 0.875 to 1.00), and Scale Content Validity Index (S-CVI/Ave = 0.941) both showed good validation scores. Test-retest reliability showcased an Intraclass Correlation Coefficient (ICC) of > 0.7, indicating its reliability. The model was constructed via the EFA resulting in four constructs, and the model's goodness of fit was confirmed with CFA. An internal reliability was calculated with Cronbach's Alpha and showed acceptable reliability (α-values > 0.6) for all constructs. The KAP questionnaire of methamphetamine use is a valid and reliable tool that can be used among Malaysian adolescents. The model arising from this study, can also be used as a guide for future intervention models for adolescent methamphetamine-use disorder.
甲基苯丙胺是一种合成的精神兴奋剂，在青少年和青年中使用呈上升趋势。其有害的副作用和高度成瘾的风险是一个公共卫生问题。认识到青少年对甲基苯丙胺的知识、态度和行为（KAP）对于规划干预策略至关重要。目前，缺乏关于甲基苯丙胺的 KAP 问卷。本研究旨在为马来西亚青少年开发和验证一份关于甲基苯丙胺使用的 KAP 问卷。在进行了广泛的文献回顾之后，在医护人员、公众、学生和当地主题专家中进行了内容和表面效度测试。在 50 名学生中进行了一项试点研究，以评估重测信度。然后，将问卷分发给两组，每组 269 人和 331 人，分别进行探索性（EFA）和验证性因素分析（CFA）。这些组的内部可靠性也进行了评估。内容验证包括项目内容效度指数（I-CVI，范围从 0.875 到 1.00）和量表内容效度指数（S-CVI/Ave=0.941），均显示出良好的验证分数。重测信度显示出>0.7 的组内相关系数（ICC），表明其可靠性。通过 EFA 构建模型，得到四个结构，通过 CFA 验证模型的拟合度。使用 Cronbach 的 Alpha 计算内部可靠性，所有结构的可靠性均可接受（α值>0.6）。使用本研究得出的模型，可以作为青少年甲基苯丙胺使用障碍的未来干预模型的指南。
