| Summary: | This thesis investigates how people make judgements of their sleep quality and thetemporal association between sleep and physical activity in people with and withoutchronic pain. In doing so, the thesis used a multi-methodological approach comprisingqualitative (Chapter 3), experimental (Chapter 4) and daily process studies (Chapters 5and 6). The qualitative study presented in Chapter 3 explored how people with andwithout chronic pain define their sleep quality and to what extent judgments of sleepquality differ with the presence of pain (n= 17). The experimental study presented inChapter 4 quantitatively examined the relative importance of 17 parameters of sleepquality in good and poor sleepers (n= 100). This study conceptualised sleep quality as adecision-making process and used a choice-based conjoint analysis to identifyparameters that shape people's judgement of sleep quality. Then the thesis shifts itsfocus to the relationship between sleep and physical activity in Chapters 5 and 6. Usingself-reported measures, the daily process study presented in Chapter 5 investigated thetemporal within-person association between sleep and physical activity in healthy youngadults (n= 118). Using both self-reported and objective measures of sleep and physicalactivity, 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 ofpain and other psychological variables (e.g., mood) that may interact with sleep to affectthe regulation of physical activity. The results across studies converge to suggest thatsleep quality judgement is a retrospective decision-making process dependent on bothdaytime and nighttime processes and that subsequently influence daytime functioningsuch as physical activity and mood in chronic pain patients. Therefore, futureinvestigations and interventions should consider the possibility of broadening the focusto addressing chronic pain patient's perception of sleep quality and the impact of poorsleep on daytime processes, for improving sleep quality, engagement in physical activityand the overall quality of life. |
