Interoceptive mechanisms of a mobile heart rate variability biofeedback app for eating disorder symptoms: Proof-of-concept findings.
Article in Eating behaviors, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionRecent US-based datasets (Ns > 1000) show over 1-in-4 adults suffer from clinically significant eating disorder (ED) symptoms. Methods for preventing subthreshold problems from becoming full-threshold EDs are needed. An 8-week, single-arm feasibility study of a mobile heart rate variability biofeedback (HRVB) app supported strong acceptability and preliminary efficacy for reducing ED symptoms. The present study investigated potential mechanisms of change from pre- to post-intervention.
methodParticipants were 24 healthcare workers recruited during the COVID-19 pandemic who scored in the clinically significant range on the Loss of Control Eating Scale-Brief (LOCES-Brief) (92 % female, 83 % non-Hispanic white, Mean age = 42; SD = 11.8). Measures included the eight subscales from the Multidimensional Assessment of Interoceptive Awareness-2 (MAIA-2) for interoceptive sensibility, and the Eating Disorder Examination-Questionnaire 7-item Short (EDE-Q7) and LOCES-Brief for ED symptoms. Mediation analyses were conducted using the MEMORE macro for repeated measures, with indirect effects evaluated via 95 % Monte Carlo confidence intervals.
resultsSignificant indirect effects on EDE-Q7 scores were found for MAIA-2 'noticing', 'attention-regulation', 'emotional-awareness', 'self-regulation', and 'body-listening' subscales. 'Not-worrying', 'not-distracting', and 'trusting' did not significantly mediate EDE-Q7 changes. For LOCES-Brief, significant indirect effects were found for 'trusting'. No other MAIA-2 subscales showed statistically significant indirect effects for LOCES-Brief.
conclusionFindings suggest HRV biofeedback may reduce ED symptoms by enhancing interoceptive skills. These results support further investigation into biofeedback as a low-cost, scalable intervention for populations at risk for EDs. Future studies should evaluate fully powered controlled efficacy trials of mobile HRVB as a preventive strategy for eating and body-related mental health concerns.
