Developing Midlife Metacognitive Strategy Training (M-MCST) program: A feasibility study with middle-aged adults to evaluate the design, implementation, and impact of a novel program in fostering healthy cognitive aging.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMetacognitive skills mediate the role of cognitive reserves in aging and facilitate effective cognitive abilities. Metacognitive deficits may precede cognitive impairments, making it important to optimize metacognition as early as middle adulthood to promote cognitive communicative well-being. Thus, the present study aimed to develop and evaluate the feasibility of a novel metacognitive strategy training (MCST) program with neurotypical middle-aged adults (MAAs).
methodThis study aligns with the initial stage of the National Institutes of Health (NIH) Stage Model for Behavioral Intervention Development. A modified nominal group technique was employed, involving a panel of five healthcare professionals to draft the strategy and execution-related aspects of the M-MCST. The feasibility of the developed protocol was then tested with twenty neurotypical middle-aged adults (MAAs) (Experimental group (EG)- 10; Control group (CG)- 10), on parameters such as recruitment, retention, adherence, changes in their cognitive performance, absolute self-estimation, and self-perception of performance using the Contextual Memory Test (CMT). Additionally, the EG participants provided reflections on the program's design, implementation, and impact to gauge participant acceptability of intervention.
resultsThe MCST comprises seven sessions incorporating the adapted 'stop-think-plan-do-check' metacognitive strategy, client-centered personalized goal selection, and a daily diary method for tracking progress. Feasibility testing revealed 100% recruitment, retention, and protocol adherence along with significant improvements in CMT performance, absolute self-estimation discrepancy, and self-perception of performance among trained MAAs. The participants found the design and implementation aspects of the training program to be promising.
conclusionThe MCST program guides healthcare professionals in the use of metacognitive strategy training with neurotypical adults, embedding it within everyday tasks. It incorporates mechanisms for monitoring strategy use, error awareness, and self-reflection through daily diaries. The findings demonstrate that the program is feasible and acceptable to MAAs and shows potential benefits for improving performance on the CMT and related metacognitive functioning. These findings support further evaluation of the program in large-scale efficacy trials and future investigations examining its potential contribution to broader constructs, such as cognitive reserve and healthy cognitive aging.
