Differences in Medical Outcomes Study - Short Form-12 physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), mental health (ME), physical component summary (PCS), and mental component summary (MCS) scores among the anxiety and sleep disturbance latent classes. All values are plotted as means ± standard deviations. For the RP, BP, GH, VT, SF, RE, MH, and MCS domains, post hoc contrasts demonstrated that the differences among the classes followed the same pattern (i.e., No Anxiety and Low Sleep Disturbance class > Moderate Anxiety and High Sleep Disturbance class > High Anxiety and Very High Sleep Disturbance class (all, p < 0.00)). For the PF and PCS domains, post hoc contrasts demonstrated that that the differences among the classes were as follows: No anxiety and Low Sleep Disturbance class > Moderate Anxiety and High Sleep Disturbance and High Anxiety and Very High Sleep Disturbance classes (both, p < 0.001).
