Data was collected by giving and filling out the Pittsburgh Sleep Quality Index (PSQI) questionnaire to assess sleep quality. Then proceed with attention checks using Attention Network Test (ANT).

Median epiction of orienting based on good sleep quality was 28.00 ms and poor sleep quality was 32.00 ms. Median depiction of executive attention based on good sleep quality was 142.29 ms and poor sleep quality was 170.00 ms. There was no correlation between sleep quality with alerting (p = 0.631 and r = 0.062), orienting (p = 0.892 and r = 0.018) and executive attention (p = 0.085 and r = 0.221) Conclusion: There is no relationship between sleep quality and attention (alerting, orienting and executive attention).]]>
