A person's total perception of his or her value or worth is referred to as self-esteem. It may serve as a proxy for how much a person "values, approves of, appreciates, prizes, or likes [him or herself]". The study's major goals were to assess adolescents' levels of self-esteem and examine the impact assertiveness training had on those adolescents' self-esteem. The research design selected for the study was pre-experimental one group pre-test and post-test research design". Anon-probability convenience sampling technique was used to obtain a sample of 60 adolescents who fulfilled the inclusion criteria. Rosenberg Self-Esteem Scale was the study's primary instrument, a 10-item questionnaire that a person fills out and scores on a 0-3 scale, containing both positive and negative items, is used to measure one's degree of self-esteem. In this case, questions 2, 5, 6, 8, and 9 had lower scores than questions 1,3,4,7 and 10. The Likert scale looks like this: Strongly disagree, strongly agree, agree, and disagree. The mean Self-Esteem score prior to the test was 11.33 with a standard deviation of 1.28, whereas the mean Self-Esteem score after the test was 21.16 with a standard deviation of 1.94. The mean difference of 9.83 is significant at 0.001 levels. The 't' value of 33.4 was higher than the table value. This study provides evidence of adolescents' self-esteem has been improved through assertiveness training.
