Abstract

Research on sleep has proven that poor sleep quality leads to negative consequences academically, physiologically, and psychologically. Drawing from previous research surrounding sleep quality, academic performance and mental well-being this study aimed to expand on previous literature by exploring underrepresented demographic factors. The hypothesis presented that poor sleep quality would lead to poor academic performance and mental distress while attributing to demographic factors. Participants were recruited through social media using a snowball sampling technique (N=112) and completed an anonymous online survey containing demographic questions, The Pittsburgh Sleep Quality Index Scale (PSQI), Academic Performance Questionnaire (APQ), and the Depression, Anxiety, Stress Scale (DASS21). Results showed that age did not affect sleep quality, women reported poorer sleep quality and increased mental distress compared than men, however, these findings do not support the hypothesis that these results affect academic performance amongst female participants. And that Irish participants report poorer academic performance than non-Irish participants, despite their being no relationship between Irish participants and poor mental well-being compared to non-Irish participants. The results of the study suggest that a controlled sample may be a more effective approach when understanding the effects of demographic factors on sleep quality.
