Objective: To investigate the effects of Quran memorization on psychological and health well-being, particularly on intelligence quotient (IQ), quality of life (QOL) and hormone levels in students of selected secondary schools in Selangor, Malaysia.
Materials and Methods:A cross-sectional study was conducted on 159 Quran memorizers from five schools in Selangor. 36-item from Short Form Health Survey (SF-36) and Wechsler Abbreviated Scale of Intelligence Second Edition (WASI-II) for assessment of the QOL and IQ were completed. Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI) and Full-Scale IQ (FSIQ) were scored. Serum serotonin and cortisol levels were also determined.
Results: The results showed that mean score for FSIQ was 104.00±14.58 and there were significant differences (p<0.05) of physical component of QOL, serotonin level, VCI and PRI as well as FSIQ scores according to the level of Quran memorization. A moderate correlation was also found between the level of Quran memorization and VCI (r= 0.356, p<0.05).
Conclusion: In conclusion, this study suggests that practice of Quran memorization positively affects IQ, QOL and the serotonin level. The implication of this study shows that people who memorize Quran present with a better physical health status.
