Spiritual Intelligence and its Relationship with Happiness and Resilience among Undergraduate Muslim Students

University life is one of the most challenging stages individuals can face. Due to environmental changes, university students encounter various physical and emotional difficulties, which, if not managed properly, can negatively affect their physical and mental health. This study examines the relationship between spiritual intelligence, happiness, and resilience among undergraduate Muslim students at a public university in Malaysia. The sample comprised 287 respondents selected through convenience sampling. A survey was created using Google Forms and distributed randomly across various online and on-site platforms. The study employed three measurement tools: the 24-item Spiritual Intelligence Self Report Inventory (SISRI-24), the Subjective Happiness Scale (SHS), and the Brief Resilience Scale (BRS). The Pearson correlation coefficient between spiritual intelligence and happiness was 0.249, indicating a weak positive correlation. Similarly, the coefficient between spiritual intelligence and resilience was 0.201, also suggesting a weak positive correlation. Despite these weak correlations, the study reveals a significant positive relationship between spiritual intelligence and both happiness and resilience among undergraduate Muslim students. This research offers valuable insights for educational institutions, highlighting the need to develop more effective programmes to enhance students' spiritual intelligence. By doing so, universities can foster greater happiness and resilience, helping students navigate life’s challenges more effectively.
