Objective and subjective sleep quality in adolescence : relations With pubertal stage, affect, and functional brain connectivity
Abstract/Contents
- Abstract
- Sleep quality decreases dramatically during adolescence. Part of this reduction is due to pubertal-related changes, which in combination with social and psychological factors can lead to long-lasting impairments in sleep quality and affective functioning, particularly during a developmental period when the brain is maturing. In this dissertation, I measure a diverse set of objective and subjective sleep parameters using ecological momentary assessment and actigraphy in a community sample of mid- to post-pubertal adolescents. Given relatively few reports of subjective and objective sleep quality in relation to pubertal stage in a single sample, my first aim is to characterize associations of pubertal stage with subjective sleep satisfaction, objective sleep efficiency, objective and subjective sleep duration, and circadian preference. We found that, regardless of age, pubertal stage was associated with subjective sleep satisfaction, but not with any of the other sleep measures. Based on these findings, in my second aim, I investigate whether positive and negative affect (PA and NA, respectively) are associated with subjective sleep satisfaction, as opposed to sleep duration, and whether pubertal stage is related to PA and NA. We found that 1) higher NA and lower PA were related to poorer sleep satisfaction, but were not related to subjective sleep duration; and 2) advanced pubertal stage was associated with NA, but not with PA. Finally, given brain-based explanations for the association between puberty and affective difficulties, and because sleep is controlled by the brain, in my third aim I test whether measures of sleep are correlated with patterns of resting-state functional connectivity (FC) that have been previously found to be associated with impairments in sleep. I expand on previous reports linking experimentally-induced sleep restriction and FC by examining the relation between naturalistically-assessed objective and subjective sleep quality and intrinsic brain networks in this sample of mid- to post-pubertal adolescents. We found that higher FC within the anterior default mode network was associated with a circadian preference towards morningness. These findings are consistent with previous reports that objective and subjective sleep quality, including circadian preference, have different psychological and biological correlates. Longitudinal data are needed to test a mechanism by which sleep and the brain interact to explain the association between pubertal stage and affective difficulties. The findings from this project may help researchers generate testable hypotheses for understanding how intervention might best be possible during this vulnerable developmental period.
