Self-care in children and young people with complex chronic conditions instrument: development and content validation.
Article in International journal of nursing studies advances, 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
Introduction: The numbers of children and young people living with chronic conditions are rising, with many experiencing significant functional limitations and complex healthcare needs. As life expectancy improves, there is a growing need to support families in managing care at home and promoting age-appropriate self-care behaviors. Existing frameworks provide evidence that self-care is essential for maintaining health, monitoring and managing changes, as it evolves with the child's development. Few instruments comprehensively assess self-care in pediatric populations or consider the role of parents. Objectives: To develop and initially validate an instrument designed to assess self-care behaviors in children and young people with complex chronic conditions, and the contribution of their parents across different developmental stages. Methods: This initial validation study, conducted between 2022 and 2023, included four phases: 1) scale development based on theoretical evidence; 2) content and face validation through expert interviews; 3) calculation of Content Validity Indexes; and 4) cognitive interviews for face validity. Eleven variants of the instrument were developed to tailor it to five age groups and addressed three core dimensions of self-care: maintenance, monitoring, and management. Eighty-six expert participants (healthcare providers, parents, and patients) took part in phases 2 and 3, while cognitive interviews were conducted with 5 patients and 13 parents in phase 4. Statistical analyses included Item-Content Validity Indexes and Scale-Content Validity Indexes. Results: The final instrument, with an average of 37 items per variant, showed strong content validity, with Scale-Content Validity Indexes ranging from 0.91 to 0.98 and Item-Content Validity Indexes between 0.63 and 1. Minimal item revisions were made based on experts' feedback. The instrument demonstrated good face validity and feasibility for online administration, with completion times between 6 and 14 min. Discussion: A new comprehensive instrument that measures self-care behaviors in children and young people with complex chronic conditions and the contribution of parents was developed, considering the various developmental stages. Initial evidence supports its content and face validity. Study registration: The study was 'not registered' in any public registry.
