The present study aims to investigate the relationship between Gardner’s multiple intelligences and academic self-efficacy and academic vitality, as well as to examine the predictive power of multiple intelligences in predicting academic self-efficacy and academic vitality among male first middle school students. This study is quantitative in nature and employs a descriptive-correlational research design. The statistical population consists of male first-cycle middle school students in District 3 of Tehran, from which a sample of 150 students will be selected using cluster random sampling. Data will be collected using the 80-item Gardner Multiple Intelligences Questionnaire, the 10-item McIlroy and Bunting Academic Self-Efficacy Questionnaire, and the 9-item Dehghanizadeh and Sarchahi Academic Vitality Questionnaire. Multiple intelligences will be examined across eight dimensions: linguistic, logical-mathematical, visual-spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic intelligence. The questionnaires will be completed through self-report, either in person or online. Following data collection and coding, the data will be entered into SPSS and analyzed using descriptive statistics, including the mean and standard deviation, as well as inferential statistical methods, including Pearson’s correlation coefficient and multiple regression analysis. Participation in the study will be entirely voluntary. Before completing the questionnaires, participants will be informed about the purpose of the study and how their information will be used. All collected information will be kept confidential and used solely for research purposes.
