This type of sleep deficit may also be a risk factor for subsequent mood episodes; however, the long\u2010term impact of sleep deficit remains unclear. The current study is among few longitudinal studies to assess the prospective effect of sleep deficit on depression and mania.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> A subsample of 54 individuals from a longitudinal study of bipolar I disorder was selected. Participants entered the study during a mood episode. Baseline symptom data were collected at month 4 to allow for recovery from the initial episode, sleep was assessed at month 6, and follow\u2010up symptom data were obtained during months 7\u201312.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Sleep deficit predicted depressive symptoms across the 6\u2010month follow\u2010up but not mania.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> It is likely that the impact of sleep deficit on mania was probably missed because assessments covered a full month.
