In general, we discourage the use of the datasets for new research without contacting the developers of the datasets first. If you require more recent data or want to discuss your research ideas, please do not hesitate to contact us↗.
General Description
The insomnia-psyctr dataset is a meta-analytic research domain (MARD; see the MARD framework paper) within the Metapsy project. It includes study information and effect sizes from randomized trials of psychological treatments versus control conditions in adults with chronic insomnia. The date of the last search is available here.
Treatments cover cognitive behavioural therapy for insomnia (CBT-I) and related approaches, coded as CBT-I (cbt), behavioural therapy (bt), cognitive or third-wave therapy (ct), and relaxation (re), in any delivery format. Controls are waitlist (wl), no treatment (nt), placebo or attention control (plb), and psychoeducation or sleep hygiene (pe). Outcomes include insomnia severity (e.g. ISI, PSQI) at post-treatment and long-term follow-up (3–12 months), sleep diary measures (sleep efficiency, total sleep time, sleep onset latency, wake after sleep onset), and remission.
The dataset follows the Metapsy data standard.
