Cognitive training at home for clinically defined insomnia: effects on sleep and psychological functioning.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Insomnia is widespread globally and is often maintained by dysfunctional cognitive-emotional processes. This open-label feasibility study examined whether participation in a home-based computerized cognitive training (CCT) program implemented via a commercial platform was associated with changes in sleep and related outcomes in adults from the general population reporting persistent sleep difficulties. Methods: Thirty-two adults completed a four-week CCT intervention delivered via the CogniFit platform. The program consisted of 20 self-guided training sessions (∼45 min each), combining cognitive tasks targeting attention, memory, and executive functioning. Standardized self-report questionnaires and a computerized cognitive battery were administered immediately before and after the intervention to assess sleep quality, mood, cognition, and quality of life. Changes over time were examined using repeated-measures analyses, with Gender included as an exploratory between-subjects factor. Results: Relative to baseline, post-intervention assessments showed statistically significant reductions in insomnia severity and sleep complaints, along with decreases in depressive symptoms and worry. Changes were also observed in executive functioning and global cognitive performance. No significant change was found in self-reported quality of life. Exploratory analyses indicated gender-related differences in depressive symptoms, worry, and executive functioning. Conclusions: In this community sample, participation in a cognitively oriented computerized training program was associated with changes in sleep-related, emotional, and cognitive measures over time. Given the single-group feasibility design and modest sample size, these findings should be interpreted as preliminary and do not allow conclusions regarding clinical efficacy. Larger randomized controlled trials are needed to determine whether such cognitively focused interventions provide benefits beyond non-specific effects and to clarify their role as adjuncts within multimodal approaches to insomnia.
