Effectiveness of School-based Substance abuse Prevention Programme (SSPP) on awareness, attitude, peer pressure, and life skills among adolescents in selected public schools of Pokhara, Nepal–A cluster randomized trial protocol

Objective: Early substance use has been linked to various adverse outcomes and escalates quickly during adolescence. Delaying the onset of substance use among adolescents is a primary public priority as it is associated with severe effects. The objective of the study is to develop and determine the effectiveness of a School-based Substance Abuse Prevention Programme (SSPP) on awareness, attitude, peer pressure, and life skills towards preventing substance abuse among adolescents. Method: Phase I of the study is a qualitative approach, where a focus group discussion (FGD) will be conducted among different stakeholders to explore their perceptions regarding the prevention of substance use among adolescents. The anticipated sample size is 38. Thematic analysis will be done by using ATLAS.ti software. The inputs given by the stakeholders will be incorporated in developing the intervention (SSPP). Phase II is a cluster randomized controlled trial. A minimum of 210 adolescents (105 each in the intervention and control groups) between the age group of 13 to 15 years from 8^th and 9^th grade will be recruited for the study. In this study, the school will be the cluster and will be randomly assigned either to an intervention or control arm. The data will be collected at pre, post, 3-month, and 6-month intervals. The ethical approval was obtained from the Nepal Health Research Council Committee, Nepal (NHRC 276/2023). The trial was also registered under the Clinical Trial Registry of USA-Clinical Trials.gov (CTRI 06004726/2023/08/22/). Descriptive and inferential statistics will be used to analyze the data. Expected results: Implementation of the SSPP module will improve the awareness, attitude, peer pressure, and life skills of adolescents toward preventing substance use behavior. Overall, the study aims to achieve Sustainable Development Goal (SDG) 3.5- ‘Good Health and Well-being; strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol.’ Conclusion: The present study protocol will help to develop a unique training module (SSPP) focused on preventing substance use behaviour among adolescents in Nepal.
