As shown in Table 4, the predictors of morning fatigue at the time of the simulation visit (i.e., intercept) were: FCs’ baseline level of trait anxiety, baseline level of family support, and patients’ baseline level of morning fatigue. However, no predictors of the linear slope were identified in this analysis. Also noteworthy is the finding that the predictors of baseline levels of morning fatigue in FCs, differed completely from those that predicted baseline levels of morning fatigue in patients in this cohort (i.e., age, baseline level of sleep disturbance, and baseline level of depression) (Miaskowski et al., 2008). One potential reason for these differences may be that all of the FCs were women, while the patients were all men. However, this finding warrants additional investigation.
