Logotherapeutic Approach in Managing Substance Abuse among Secondary School Students in Borno State'. Seven objectives and seven null hypotheses were formulated. The objectives of the study include: to determine the efficacy of Modification of Attitude Technique of Logotherapy on subjects in experimental group one before and after treatment and to determine the efficacy of Socraic Dialogue Technique of Logotherapy on subjects in experimental group two before and after treatment among others. Other objectives were to find efficacy of Modification of Attitude and Socraic Dialogue Techniques on the levels of Substance abuse, to find differences in post test scores of subjects exposed to treatment by Modification of Attitude and Socraic Dialogue Techniques and to determine the efficacy of the two techniques on male and female. Some of the null hypotheses were: there is no significant effect of Modification of Attitude Technique of Logotherapy on subjects in experimental group one before and after treatment, there is no significant effect of Socraic Dialogue Technique of Logotherapy on subjects in experimental group two before and after treatment. Other hypotheses sought to find significant effects of Modification of Attitude and Socraic Dialogue Techniques based on levels of substance abuse and gender. The study was conducted using quasi experimental pre -test post-test group design. The population of the study was all secondary school 2 students in Biu Educational Zone who were involved in substance abuse. Thus, 483 students drawn by the use of Substance Abuse Checklist (SAC) from 12 secondary schools constituted the population of the study. Two secondary schools were selected based on percentage of students that were involved in substance abuse as experimental school one and experimental school two on which a different technique of Logotherapy was administered on 12 subjects each selected randomly from those involved in substance abuse. The xix schools were purposively assigned to experimental groups. A twenty one item questionnaire that is Substance Abuse questionnaire (SAQ) adapted from a guideline provided by the Centre for Substance Abuse Treatment on a five point likert scale was used for both pre-test and post-test exercises. The hypotheses were tested using t-test and Analysis of Variance at 0.05 level of significance. The major findings revealed that there was significant effect of modification of Attitude and Socratic Dialogue techniques of Logotherapy on mild and moderate levels of substance abuse behavior (F-52.053, P-0.000), Subjects exposed to socratic Dialoloque technique of Logotherapy had reduced substance abuse behavior after the post-test exercise compared to the pre-test result (t=4.245, P=0.001). There was no significant gender difference among subjects exposed to treatment by modification of Attitude technique of Logotherapy (t=0.062, p=0.095). School administrators and all teachers in secondary schools should be encouraged to learn and use Logotherapeutic techniques of Modfication of Attitude and Socratic Dialogue techniques to manage substance abuse in the schools and the society at large.
