Clinical rating scales (POMS, BDI, BAI), lower scores reflect lower levels of clinical symptoms; BIS-11, lower scores indicate lower levels of self-reported impulsivity; PSQI, lower scores reflect improved sleep quality; SF-36, higher scores indicate higher quality of life. adf = 1,21; bdf = 1,18; ∗bolded results are significant at p ≤ 0.05; ˆ italicized results approach significance at p ≤ 0.10.
