Validation and Administration of the Spanish Questionnaire 'Humanisation of Pediatric Care in Pain Management with a Non-Pharmacological Approach (HUPEDCARE-Q)'.

: The pain associated with invasive procedures is one of the most common experiences in the pediatric population. Its management remains insufficient due to gaps in healthcare training and knowledge. The aim of this study was to analyze the attitudes, beliefs, care practices, and training of healthcare professionals in relation to pediatric pain, through the development and application of the questionnaire 'Humanisation of Pediatric Care in Pain Management with a Non-Pharmacological Approach (HUPEDCARE-Q)'. : A cross-sectional, observational, and descriptive study with a quantitative approach was conducted to validate a questionnaire. The process was carried out in three phases: (1) design and initial development of the instrument; (2) evaluation of content validity through expert judgment, using the Content Validity Coefficient (CVC); (3) administration of the questionnaire to a large sample of healthcare professionals to assess its internal consistency and psychometric structure. : The evaluation involved five experts, and the items were assessed using the Content Validity Coefficient (CVC), with the overall CVC of the questionnaire exceeding 0.80. The average item scores given by the experts ranged from 0.88 to 0.95, indicating a high level of agreement in their evaluations. The results showed statistically significant positive correlations among most items ( < 0.001), indicating adequate internal consistency. : The content validation and pilot study confirmed the theoretical relevance and appropriateness of the HUPEDCARE-Q questionnaire items in the Spanish context. The results support its usefulness as a valid and reliable tool to identify attitudes, beliefs, knowledge, and training needs in the humanized management of pediatric pain.
