This thesis investigates how people make judgements of their sleep quality and the emporal association between sleep and physical activity in people with and without chronic pain. In doing so, the thesis used a multi-methodological approach comprising qualitative (Chapter 3), experimental (Chapter 4) and daily process studies (Chapters 5 and 6). The qualitative study presented in Chapter 3 explored how people with and without chronic pain define their sleep quality and to what extent judgments of sleep quality differ with the presence of pain (n= 17). The experimental study presented in Chapter 4 quantitatively examined the relative importance of 17 parameters of sleep quality in good and poor sleepers (n= 100). This study conceptualised sleep quality as a decision-making process and used a choice-based conjoint analysis to identify parameters that shape people’s judgement of sleep quality. Then the thesis shifts its focus to the relationship between sleep and physical activity in Chapters 5 and 6. Using self-reported measures, the daily process study presented in Chapter 5 investigated the temporal within-person association between sleep and physical activity in healthy young adults (n= 118). Using both self-reported and objective measures of sleep and physical activity, a follow-up daily process study was conducted in people with chronic pain (n= 51, Chapter 6). In addition, the study presented in Chapter 6 also explored the roles of pain and other psychological variables (e.g., mood) that may interact with sleep to affect the regulation of physical activity. The results across studies converge to suggest that sleep quality judgement is a retrospective decision-making process dependent on both daytime and nighttime processes and that subsequently influence daytime functioning such as physical activity and mood in chronic pain patients. Therefore, future investigations and interventions should consider the possibility of broadening the focus to addressing chronic pain patient’s perception of sleep quality and the impact of poor sleep on daytime processes, for improving sleep quality, engagement in physical activity and the overall quality of life.
