Researchers report that depression and anxiety may impact a patient’s report of sleep quality, as reported by HCP Live.

The goal was to see how accurately patients remembered and reported their sleep quality on the PSQI.
They found the patients who didn’t have psychiatric symptoms reported their actual sleep quality fairly accurately when compared to the diary entries they kept (P < 0.001 between PSQI and SDSQ). Those with anxiety or depression, meanwhile, reported worse sleep quality on the PSQI than they did in their diary entries (P = 0.47).
“These findings confirm the notion that psychiatric patients may be more biased in their retrospective ratings than individuals without psychiatric symptoms,” the authors wrote.
