Happiness and Attention Deficit/Hyperactivity Disorder Symptoms as Mediated by Subjective Health Conditions: A Nationwide Cross-Sectional Internet Survey.
Article in Neuropsychopharmacology reports, 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
objectivesThere has been limited examination of happiness among individuals with attention-deficit/hyperactivity disorder (ADHD), despite growing interest in psychiatric comorbidities associated with this disorder. This study aims to fill this gap by exploring the relationship between ADHD symptoms and happiness on the basis of data from the Japan Society and New Tobacco Internet Survey (JASTIS).
methodA nationwide, cross-sectional internet survey was conducted in Japan between January and February 2024. The analytic sample comprised 29 268 individuals aged 16 years and above in Japan. Based on questionnaire responses of the 6-item short version of the Japanese version of the Adult ADHD Self-Report Scale (ASRS-J-6), the respondents were classified as possible ADHD or not. Information on happiness was collected via a single (10-point Likert scale) measure.
resultsMultivariable ordinal logistic regression analysis and a mediation analysis were performed to examine associations. Possible ADHD was associated with increased odds of feeling less happy. Very high somatic symptoms (41.1% mediation), confusion/difficulty to concentrate (37.2%), and depression (14.8%) were important mediators of the association between ADHD and happiness.
conclusionsAlthough the majority of individuals with possible ADHD were classified as having moderate happiness, more than one in four were classified as having low happiness. To increase the happiness of individuals with ADHD, screening and treating for both physical and psychiatric symptoms might be important.
