PMID 39833657WHAT IT FOUND
Liver transplant recipients reported high uncertainty and poor sleep.
Younger age was linked to more uncertainty, and complications were linked to worse sleep. Prospective anxiety was linked to poor sleep, but it did not explain poor sleep by itself.
Key findings
0165% of liver transplant recipients scored above the Pittsburgh Sleep Quality Index cut-off of 5, indicating poor sleep quality.
02Mean intolerance of uncertainty was 41.04 of 60, and each 1-year increase in age was associated with a 0.266-unit decrease in intolerance of uncertainty, with age explaining 5.1% of the variance.
03Post-transplant complications explained 14.3% of variance in sleep quality and were associated with a 4.170-point higher mean PSQI score, while prospective anxiety was related to sleep quality but was not predictive.

What it does not show
The study was done in one transplant center, so results may not apply to all liver transplant recipients. It was cross-sectional, so it cannot show how uncertainty or sleep changed before and after transplantation. People with prior psychological or mental diagnoses were excluded, so findings may not apply to recipients with known anxiety, depression or psychosis. Data were self-reported at one time point, with no control group. The study examined only selected variables, so other psychological and lifestyle factors were not assessed.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not conclude that intolerance of uncertainty causes poor sleep or that counselling about uncertainty will improve sleep. The study was cross-sectional, total intolerance of uncertainty was not significantly related to sleep quality, and prospective anxiety was not predictive of sleep quality.
