This online survey study of 141 university students examined the impact of sense of belonging, resilience, time management skills, and academic performance on their psychological wellbeing. Results showed that resilience significantly predicted psychological well-being. Resilience and time management predicted environmental mastery. Both resilience and time management skills also predicted autonomy, but time management seemed to be more important than resilience in predicting autonomy. Sense of belonging and academic performance added a minimal significant amount of variance to self-acceptance, but neither were significant predictors for the measure. The inconsistency between some of our findings and the current literature may be attributed to the use of more senior tertiary students who experienced high pressure to perform well academically and displayed less variability in their academic achievement. This study is correlational and cannot imply any causality. It would be beneficial to carry out experimental studies to see how training on resilience, time management, sense of belonging and academic performance affect one's psychological well-being.
