This study examined the associations among neuroticism (N), conscientiousness (C), and sleep quality in the context of a life transition. The interactive effects of N and C on the association between sleep quality and mental and physical well-being were also examined. Seventy-seven college freshmen (mean age = 19.5) completed personality measures at the beginning of the academic year, and measures of sleep quality, daily hassles, functional status, depression, and self-assessed health approximately 2 months later. N was negatively and C was positively related to sleep quality, and daily hassles mediated these associations. Poor sleep predicted greater depressive symptoms and poorer functional status for high-N/low-C participants, but not for other N and C profiles. Results suggest that conscientiousness moderates the extent to which high-N individuals are vulnerable to the adverse effects of poor sleep. (C) 2008 Elsevier Ltd. All rights reserved.
