Development and validation of a Knowledge, Belief, and Behaviour Questionnaire on Sarcopenia for Older Adults (KBBQ-SOA): a study protocol based on the COSMIN guidelines.
Article in BMC geriatrics, 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
backgroundThe lack of a standardized and theoretically grounded instrument to assess psychosocial determinants of sarcopenia prevention represents a critical gap in public health. This protocol describes the development and validation of the Knowledge, Belief, and Behaviour Questionnaire on Sarcopenia for Older Adults (KBBQ-SOA).
methodsGuided by the Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) and informed by the Knowledge-Belief-Behaviour framework, the study will be conducted in four sequential stages: (1) item generation and construct clarification through literature review, expert consultation, and semi-structured interviews; (2) content validation using a Delphi expert panel and cognitive interviews; (3) psychometric evaluation in a multi-site sample of 300–500 community-dwelling older adults across four diverse regions of China; and (4) assessment of interpretability and feasibility, including a preliminary evaluation of cross-cultural applicability. OUTCOMES: This paper presents the study design and methodology; no results are reported.
conclusionThe KBBQ-SOA is expected to be a rigorously validated, multi-dimensional instrument for assessing sarcopenia-related knowledge, beliefs, and behaviours. It may support the development and evaluation of targeted health education and behavioural interventions in older adult populations.
