Opioid use disorder (OUD) is a large, growing, and difficult-to-treat problem. It has been associated with poor sleep, which has a relationship of mutual exacerbation with pain. These interrelationships have prompted interest in how pain catastrophizing (pain-related distortions of cognition), interacts with pain and sleep quality and quantity in those with OUD. ⋯ Pain catastrophizing is a significant mediator of the relationship between the mutually exacerbating factors of sleep quality and pain intensity, and is, therefore, an important treatment target in this population. In addition, objective TST and self-reported TST were only moderately correlated and behaved differently in mediation models, suggesting that more research is needed to understand the relationship between perceived sleep quality and sleep quantity.
