Meta-analyses evaluated differences in effects on each sleep outcome between participants assigned to SHUTi versus online education control conditions and whether participant and study characteristics moderated effects.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Twenty-nine publications reported unique data from 25 studies testing SHUTi among diverse populations from around the world (total N=14,166). Participants who were provided SHUTi reported clinically significant improvements on all sleep metrics (average declines from baseline to follow-up timepoints were \u22658 points on ISI, \u226521 minutes SOL, \u226527 minutes WASO without EMA, and \u226535 minutes WASO including EMA), with 64% completing a full therapeutic dose of SHUTi. Of the 10 RCTs comparing SHUTi with online education, SHUTi participants reported greater improvements from baseline through post-assessment and 6- and 12-month follow-ups (ISI Standardized Mean Differences [SMD]= -1.03 \u2014 -0.85, ps&lt;.001; SOL SMD= -0.41 \u2014 -0.32, ps&lt;.024; and WASO SMD= -0.48 \u2014 -0.45, ps&lt;.001).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Individuals receiving SHUTi report clinically and statistically significant improvements in sleep, which are greater than those receiving online education. SHUTi demonstrates robust efficacy for treating insomnia across medically, psychiatrically, and demographically diverse samples.<\/jats:p>\n
