Validating an aphasia-accessible ecological momentary assessment for daily depressive affect: A preliminary investigation.
Article in Journal of affective disorders, 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
backgroundUp to 60% of individuals with aphasia have post-stroke depression, resulting in worse quality of life. However, extant measures of depression in aphasia are insufficient, and people with aphasia are often excluded from studies of depression due to a lack of valid assessment tools. Ecological momentary assessment (EMA) involves brief, repeated surveys that capture fluctuations in the real world, and may be adapted for individuals with communication impairments. We created a novel, aphasia-accessible EMA of affective depressive symptoms and evaluated its feasibility and usability in a sample of people with aphasia.
methods27 people with aphasia (Western Aphasia Battery-Aphasia Quotient (WAB-AQ) range: 32.9-97.4) completed a six-item EMA survey assessing positive and negative affect through the app m-Path four times per day for 14 days (up to 56 assessments). We analyzed feasibility, validity, and user experience of the app and surveys.
resultsParticipants completed 89.6% of the EMA surveys, indicating strong compliance and feasibility. EMA items correlated strongly with the Center for Epidemiologic Scale-Revised and Patient-Reported Outcomes Measure Information System (PROMIS) Depression measures, reflecting high convergent validity. Participants gave positive feedback about their experience using the app and answering the survey questions.
conclusionsThese results suggest that EMA is a useful tool for identifying affective symptoms of depression in people with aphasia and could be a way to address the gap in mental health care for people with aphasia. Future research should include more diverse samples as well as add passive, ecologically valid measures of depression.
