Identifying Behavior Change Techniques for Digital Interventions Addressing Alcohol and Tobacco Co-Use: Findings From a Delphi Consensus Study.
Article in JMIR formative research, 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
backgroundAlcohol and tobacco use frequently co-occur and contribute significantly to the global burden of disease. Despite the well-established benefits of addressing both behaviors simultaneously, health care professionals often face substantial challenges in delivering integrated interventions, including limited time, training, and resources. Digital health interventions offer a promising avenue to directly support patients in reducing alcohol and tobacco use, while bypassing some of the barriers encountered in clinical settings. However, there is a lack of consensus on the key behavior change techniques (BCTs) that must be incorporated to ensure that interventions are evidence based and contextually appropriate, making them effective.
objectiveThe study aims to identify expert opinions on the most suitable and effective BCTs (reflecting both behavioral relevance and delivery feasibility) to be included in a 1-time, self-guided digital intervention intended to initiate behavior change and support alcohol reduction among people trying to quit smoking.
methodsWe conducted a 2-round modified Delphi study with 14 panelists with expertise in behavioral science, alcohol and tobacco treatment, and digital interventions. Panelists rated 20 BCTs identified in a previous rapid review using the acceptability, practicability, effectiveness, affordability, safety, and equity (APEASE) criteria. BCTs were deemed "appropriate" if at least 70% (n=10) of panelists agreed on all criteria.
resultsSix BCTs were identified as appropriate for implementation: goal setting, action planning (individualized change plan), action planning (reduction strategies), feedback on behavior, reattribution, and pros and cons. These BCTs were considered effective for promoting behavior change through structured planning and personalized strategies. The panel reached partial consensus on several BCTs, while 8 BCTs were deemed inappropriate for a 1-time, unsupervised digital intervention.
conclusionsThe results of this study offer a consensus-based view, reflecting expert opinion on the perceived appropriateness and feasibility of the BCTs that should be included in a 1-time digital intervention to address co-occurring alcohol and tobacco use.
