Assess Drug Knowledge

Drug knowledge is assessed using a questionnaire developed by our team. The questionnaire consists of 12 true-or-false items adapted from the psychoeducational materials provided in the program. Participants will complete the questionnaire at baseline before the intervention, and again after the intervention ends. Drug knowledge scores will be calculated as the total number of true responses and reported as both numbers and percentages.

Measure attitudes towards drugs and alcohol

The Attitudes Toward Alcohol Use Scale and the Attitudes Toward Drug Use Scale each consist of four items. Intentions for use will be measured by asking participants to rate their intention to use various substances in the next six months on a 7-point Likert scale. Higher scores indicate greater intention to use. The scales evaluate participants' consideration of being under the influence of the respective substances. Participants complete the questionnaire at baseline, prior to the intervention, and again after the intervention has concluded. Attitudes toward drugs and alcohol will be reported using the mean and standard deviation.
