“…Firstly, the majority of extant literature has focussed on measuring overall sleep quality; therefore, it is unclear whether specific types of problems sleeping might be more or less associated with IBD‐related outcomes. Given that different types of sleep disturbances have different screening methods (Devine, Hakim, & Green, 2005; Ibáñez, Silva, & Cauli, 2018; Marino et al ., 2013) and treatment strategies (Hansen, Höfling, Kröner‐Borowik, Stangier, & Steil, 2013; Harrison, Keating, & Morgan, 2019; Iftikhar et al ., 2017; Zachariae, Lyby, Ritterband, & O’Toole, 2016), understanding whether specific types of sleep disturbances are predictive of HRQoL in IBD could facilitate suggestions that health care services should be doing more to screen for and subsequently treat sleep disturbances as part of routine care (Almedimigh et al ., 2018; Green et al ., 2017; Kinnucan et al ., 2013; Sofia et al ., 2018). Secondly, no study has examined the temporal relationship between specific sleep disturbances and HRQoL in those with IBD over time.…”
