Abstract
The present study aimed to determine whether alcohol consumption, alcohol use as a coping
strategy, extraversion, age, and gender would predict levels of sleep-wake activity and life
satisfaction in Irish individuals (N = 135). A quantitative correlational research design was
employed to assess how each predictor variable related to sleep-wake activity criterions
excessive daytime sleepiness (EDS) and nocturnal sleep (NS), as well as criterion satisfaction
with life. Standard multiple regression results indicated that the combined predictor variables
explained about 14% (p < .001) of the variance in satisfaction with life scores, with alcohol use
as a coping mechanism and extraversion level significantly predicting 10% (p < .001) and 8% (p
= .001) of the variance respectively. Participant age also significantly predicted EDS scores,
explaining 3% (p = 0.042) of the variance. The predictor variables did not significantly associate
with NS quality. Results suggest that avoidance-coping strategies such as alcohol consumption
decrease life satisfaction, and that personality trait extraversion positively moderates satisfaction
with life in individuals. Results also suggest that EDS decreases with age. Limitations of the
current study are also discussed. Author keywords: alcohol, coping, extraversion, sleep-wake activity, excessive daytime sleepiness, EDS, satisfaction with life, Ireland
