Abstract

Sleep hygiene education (SHE) as a single therapy for insomnia still lacks sufficient evidence. This study aimed to quantify the effects of SHE on insomnia treatment. A literature search was conducted on seven databases from inception up to 30 September 2024 to retrieve randomized controlled trials. Meta-analyses were performed to estimate the mean difference (MD) of Insomnia Severity Index (ISI) (primary outcome) using a random-effects model. Risk of Bias 2 tool was applied to measure methodological quality. Forty-two RCTs encompassing 4245 adults (65.5 % female) were included. The pooled results showed significant pretreatment-to-posttreatment improvement in ISI score (MD = 3.4, 95 % confidence interval (CI) [2.08, 4.64]). However, SHE was inferior as a cognitive behavioral therapy for insomnia (CBT-I) (MD = 3.8, 95 % CI [2.92, 4.76]), partial CBT-I (MD = 4.5, 95 % CI [3.33, 5.60]), exercises (MD = 2.9, 95 % CI [0.81, 5.04]), and acupressure (MD = 1.9, 95 % CI [0.82, 3.00]) regarding the ISI score. The majority of included trials (85.71 %) had a high overall risk of bias, and the remaining had "some concerns." Future work is encouraged to generate robust evidence through the development of well-designed SHE as an examined intervention for insomnia that involves process evaluation and treatment fidelity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
