Trial reportImplementation science : IS2025
A randomized trial of adapted versus standard versions the transdiagnostic intervention for sleep and circadian dysfunction (TSC) implemented via facilitation and delivered by community mental health providers using train-the-trainer.
Trial report in Implementation science : IS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05805657 (Implementing and Sustaining a Transdiagnostic Sleep and Circadian Treatment to Improve Severe Mental Illness Outcomes in Community Mental Health Part 2), which is not on this map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
backgroundGrounded in the Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, we investigated the Train-the-Trainer (TTT) to expand access to evidence-based psychological treatments (EBPTs) in community mental health centers (CMHCs), focusing on the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TSC).
methodsEight Californian counties were cluster-randomized to Standard TSC or an adapted version designed to improve the "fit" of TSC to CMHCs. University-based trainers trained CMHC providers ("Generation 1 providers") in either Adapted or Standard TSC. These trained providers were then trained to become local CMHC trainers ("Generation 1 trainers"), who then trained a new cohort of providers ("Generation 2 providers") in TSC. Within each county, patients diagnosed with serious mental illness (SMI) were randomized to receive either immediate TSC or usual care and delayed treatment with TSC (UC-DT) from the Generation 2 providers ("Generation 2 patients"). This study focused on 53 Generation 2 providers (Adapted TSC = 47; Standard TSC = 6), and 143 Generation 2 patients (Adapted TSC = 127; Standard TSC = 16) (the larger Adapted sample was driven by recruitment, perhaps reflecting preference for the "fitted" approach). Patient assessments were conducted pre-treatment, post-treatment, and six-month follow-up (6FU). Provider assessments occurred after completing TSC training and post-treatment for each patient treated.
resultsCombining Adapted and Standard, TSC was associated with improvements for Generation 2 patients from pre- to post-treatment in sleep disturbance (p < 0.001, d = -0.90), sleep-related impairment (p = 0.001, d = -0.69), psychiatric symptoms (p = 0.002, d = -0.48), and functional impairment (p = 0.002, d = -0.54), relative to UC-DT. The effects of sleep disturbance and impairment on the relationship between treatment condition (TSC vs. UC-DT) and psychiatric symptoms and functional impairment were significant. Higher provider perception of TSC fit predicted improvements in selected patient outcomes.
conclusionTSC can be delivered by CMHC providers trained by local CMHC trainers with strong outcomes. These data contribute to the dearth of evidence for TTT collected from locally trained providers and from patients treated by local CMHC trainers.
