Understanding Primary Care Dietitians' Experiences and Perspectives on Weight Management Practice Using the COM-B Model.
Article in Journal of human nutrition and dietetics : the official journal of the British Dietetic Association, 2025. 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
aimWeight management is a core area of dietetic primary practice. Understanding the behavioural drivers that influence dietitians' weight management practice is essential for gaining insight into how to better support dietitians in this area. This study used the Capability, Opportunity, Motivation-Behaviour (COM-B) model, a behavioural framework, to explore how dietitians' practice is influenced by their skills and knowledge (capability), environmental factors (opportunity) and professional desires and habits (motivation).
methodsThis qualitative descriptive study used an interpretivist approach guided by social constructionism. Primary care dietitians practising in Australia were recruited through purposive and snowball sampling for semi-structured interviews. Interviews were audio-recorded, transcribed verbatim, and analysed using content analysis. Constructed content categories were then mapped to the COM-B model to understand the behavioural factors shaping dietitians' weight management practice.
resultsFourteen primary care dietitians participated in the study; 13 were women, 11 were aged between 20 and 50 years, and 8 had over 9 years dietetic practice experience. Eight content categories were constructed and mapped against the COM-B components. Aligned with Capability, dietitians demonstrated comprehensive 'Understanding [of] Weight Management Complexity' and employed 'Holistic Practice Approaches' in their care delivery, though they found 'Navigating Clients' Psychosocial Needs' challenging. Opportunity was shaped by 'System Constraints' that influenced care provision, 'Multidisciplinary Care Environment[s]' that had varied impacts on collaborative care delivery, and 'Digital Solutions' that offered service delivery advantages. Motivation was characterised by dietitians exhibiting strong 'Professional Drive' and commitment to 'Client-centred Strategies'.
conclusionSupporting primary care dietitians requires targeted interventions across all COM-B components. Potential approaches include enhancing capability through behaviour change counselling training, improving opportunity with integration of digital technologies, and sustaining motivation through established clinical pathways that align with dietitians' client-centred values.
