Development and psychometric evaluation of the DysPalKT for assessing nurses' knowledge of dyspnoea care in patients with cancer receiving palliative care.

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
backgroundDyspnoea is one of the most prevalent and distressing symptoms among patients with advanced cancer receiving palliative care. Nurses, particularly in non-specialist settings, often report insufficient preparedness in managing dyspnoea. Despite its clinical relevance, existing tests inadequately assess nurses’ knowledge of dyspnoea care. This study aimed to develop and evaluate the Knowledge of Dyspnoea Care in Patients with Cancer Receiving Palliative Care (DysPalKT) to address this gap.
methodsThe DysPalKT was developed through a multi method approach including literature synthesis, expert panel validation, and pilot testing. A cross-sectional psychometric evaluation was conducted with 84 registered nurses working in general inpatient wards across seven district hospitals in Finland. Psychometric properties were analysed using the Kuder-Richardson Formula 20 (KR-20) and Rasch modelling.
resultsThe final test comprised 16 items across three domains. Content validity was supported by expert evaluations (I-CVI ≥ 0.83). However, KR-20 (0.306) indicated weak internal consistency, and Rasch analysis revealed low person separation and multidimensionality. Most items were too easy, limiting the test’s ability to differentiate between knowledge levels.
conclusionsThe DysPalKT shows promise for assessing nurses’ knowledge of dyspnoea care in palliative care settings, but further refinement is needed. Increasing item difficulty and expanding the item pool may improve its reliability and discriminatory power. These improvements could enhance the knowledge test’s ability to identify learning needs, thereby supporting the design and targeting of future educational interventions in non-specialist palliative care.
