Withdrawn and wired: Problematic internet use accounts for the link of neurotic withdrawal to sleep disturbances.

Although neuroticism is the strongest personality predictor of sleep disturbance, it is not clear whether dysphoric (Withdrawal) or angry (Volatility) aspect of neuroticism is more important and whether problematic technology use plays an intervening role. To this end, this study examined distinct contributions of neurotic withdrawal and volatility in predicting self-reported sleep disturbance while testing the mediating role of problematic internet use. One-hundred and fourty-three college students completed an online survey that included measures of neuroticism, sleep quality, and problematic internet use.
