Behaviour change solutions driven by cognitive insights for improving TB health care seeking among vulnerable population: an exploratory multi-state qualitative study in India.
Article in BMC public health, 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
backgroundTuberculosis disproportionately affects vulnerable groups due to low health awareness and suboptimal care-seeking behaviour. Individualised person-centric approaches are scarce in India's national TB program. This study assessed the usefulness of behaviour change solutions (BCS) in improving TB case identification and treatment adherence among mining/industrial workers, migrants, tea-garden workers, tribals, and urban vulnerable.
methodsIn this qualitative study we conducted 147 in-depth interviews (IDI) with adult (78 men, 69 women) BCS beneficiaries, facilitators (auto drivers, community leaders) and healthcare providers between May-August, 2023 in Karnataka, Telangana, Assam, and Bihar. We explored the usefulness of four BCSs - health auto (addressing decision fatigue and healthcare costs), jaanch coupon (addressing the loss aversion bias), TB starter-kit (reducing ambiguity aversion), and TB mukt certificate (reinforcing positive perceptions), through user experience. Interviews were conducted in local language (Kannada, Telugu, Hindi and Assamese), audio recorded, transcribed, and analysed using a deductive approach. A thematic analysis was done, focusing on participants' knowledge of the solutions, their experiences using them, perceived benefits and challenges, and recommendations for improvement. Thematic saturation was reached through a process of collaborative analysis, where the research team iteratively reviewed and discussed emerging patterns. The study received ethics approval from the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore.
resultsThe initial codes were merged into major themes based on their similarity. Findings indicated that health auto and jaanch coupon enhanced TB related awareness at the community level, reduced diagnostic delay, and facilitated increased case finding. On the other hand, use of starter-kit and TB mukt certificate led to improved treatment adherence. BCSs also supported timely decision-making, promoted treatment adherence, and empowered persons with TB by fostering a sense of entitlement. Moreover, BCSs attempted to address multifaceted vulnerabilities: while case finding solutions were able to facilitate accessibility and affordability by addressing physical barriers, the case holding solutions reduced stigma and improved community acceptance. However, the data also indicated that the solutions had challenges related to acceptability, and scalability.
conclusionsFindings from this study underscored that BCS catalysed TB healthcare seeking by addressing cognitive barriers. It suggests that designing targeted cognitive interventions could potentially be a promising approach to alter cognitive biases, inculcate behavioural changes, and improve TB care-seeking and treatment outcomes.
