Individuals/Students/ in those selected schools will be allocated as intervention and control group purposively. The study will include 748 students from two secondary schools for the intervention group and another 748 students for the control group from other two secondary schools. The per-educational intervention will be planned based on results of the elicitation and TPB constructs and will be implemented on the experimental group for three months. Both experimental and control groups will be followed up after three months of educational intervention using the same tools and methods on same participants interviewed in pretest survey. Primary outcomes are substance(Cigarette,alcohol and Khat) use intention and behavior. Secondary outcome are attitudes, subjective norms, and perceived behavioral control over substance(Cigarette,alcohol and Khat) use. Self-administered questionnaire based on TPB constructs will be used to collect the baseline and follow up data. In-depth interviews will be employed to explore the salient beliefs about substance use. The data will be analyzed using SPSS statistical software package version 20 using appropriate statistical tests including paired t-test, independent t-tests, McNemar and multivariate logistic regression analysis. All statistical tests will be carried out using two tailed tests with alpha set at 0.05. Information from the interviews will be transcribed verbatim, analyzed, and coded thematically.
