The aim of this study is to examine the level of
sleep quality and quality of life, and to investigate the
relationship between sleep quality, mindfulness and
quality of life among undergraduate students. Crosssectional study design was implemented. The Pittsburgh
Sleep Quality Index (PSQI), the Mindful Attention
Awareness Scale (MAAS) and the Quality-of-Life
Enjoyment and Satisfaction Questionnaire (Q-LES-Q)
were used in this study. A total of 139 undergraduate
students from a public university in Malaysia have
participated in this study. Correlation analysis was used to
analyse the data. Results showed that there was a
significant relationship between mindfulness and all
domains of quality of life particularly satisfaction with
feelings, social relations and physical health. Meanwhile,
sleep quality was also found to be significantly related with
quality of physical health and feelings. Nonetheless, no
significant relationship was found between sleep quality
and satisfaction with social relations. The obtained
findings implied that practising mindfulness significantly
increases undergraduate students’ quality of life especially
for the aspects of physical health, emotions and social
relations. Implications of the findings were discussed.
