Mental health disorders among adolescents have risen significantly in recent years, particularly following the COVID-19 pandemic, highlighting the need for effective preventive and supportive interventions. Nurses play a key role in the promotion, early detection, and management of mental health issues in adolescents, both in school and community settings. This study aimed to synthesize quantitative and qualitative evidence on the role, effectiveness, and implementation of nursing interventions for adolescent mental health. A systematic mixed-methods review was conducted in accordance with the PRISMA 2020 guidelines. It was registered in PROSPERO (CRD42024502076). Databases including PubMed, Scopus, SciELO, Dialnet, BVS, and Cuiden were searched for studies published between 2014 and 2024. Twelve studies met the inclusion criteria, comprising randomized and non-randomized quantitative studies, qualitative studies, and previous reviews. The interventions identified included cognitive-behavioral therapy programs, resilience and life skills training, physical activity initiatives, digital interventions, and mental health literacy strategies. Overall, the findings suggest improvements in symptoms of anxiety and depression, coping skills, resilience, and knowledge about mental health, particularly in structured school-based programs. Qualitative evidence highlighted the importance of accessibility, multidisciplinary collaboration, cultural sensitivity, and sustained commitment for successful implementation. However, considerable heterogeneity was observed in study designs, interventions, and outcome measures. In conclusion, nursing interventions can make a positive contribution to adolescents’ mental health, particularly in school and community settings. However, further rigorous, long-term studies are needed to strengthen the evidence base.

Background: Adequate nutritional knowledge among intensive care nurses is essential for early identification of nutritional risk and prevention of complications in critically ill patients. The questionnaire “Nurses’ perceptions of responsibility, knowledge and documentation focusing on enteral nutrition and nursing practice regarding enteral feeding in the intensive care unit”, developed by Persenius et al., is used internationally, yet no culturally adapted Spanish version has been available. Objectives: This study aimed to translate and culturally adapt Persenius et al.’s questionnaire and evaluate its content for use among Spanish-speaking intensive care unit (ICU) nurses. Materials and methods: A multistep process was conducted, including forward–backward translation, expert review by an expert panel of ICU nurses (N = 26) with at least 2 years of critical care experience, and content validity analysis. Experts rated item relevance and comprehensibility. Item Content Validity Index (I-CVI), Scale CVI, and Aiken’s V were calculated using predefined thresholds. Linguistic clarity/comprehensibility was assessed on a 5-point Likert scale (1–5). To assess the questionnaire’s reliability, Cronbach’s alpha was also analysed in a pilot study (N = 99). Results: The Spanish version retained all 47 original items after minor linguistic adjustments. All items met the minimum content validity threshold; most showed I-CVI values > 0.78 and acceptable Aiken’s V coefficients. The mean comprehensibility score for all items exceeded 4.0, indicating high clarity. No item required significant semantic modification after expert review. Cronbach’s alpha coefficient of 0.85 reflected its reliability. Conclusions: The Spanish version of Persenius et al.’s questionnaire demonstrated adequate content and linguistic validity and internal consistency in a pilot sample of ICU nurses.

The increasing digitalization of health systems has transformed the ways in which individuals and communities interact with information, health services, and decisions related to their wellbeing. In this context, health literacy, media health literacy, and the digital divide in health have emerged as critical determinants of informed and equitable participation in digital environments. The aim of this conceptual review is to examine the interconnections between health literacy, media health literacy, and the digital divide, and to propose an integrated conceptual framework to inform equitable public health practice, policy, and research in the digital era. The article provides a critical and integrated analysis of these constructs, highlighting their conceptual relationships, key methodological challenges, and implications for clinical practice, health policy development, and public health research. The findings indicate that approaches focused exclusively on individual skill development are insufficient to address digital health inequities. Without attention to structural and organizational determinants, the expansion of health technologies may reproduce or exacerbate pre-existing social and health inequalities. Accordingly, the review underscores the need for multilevel approaches that align literacy development, digital inclusion, and health system design to strengthen equity in the digital era.

The COVID-19 pandemic placed unprecedented pressure on healthcare systems and frontline professionals, particularly nurses, highlighting the importance of understanding their emotional experiences and coping strategies. This study aimed to explore the emotional experiences and coping strategies of nursing professionals during the first wave of the COVID-19 pandemic in a Spanish regional healthcare setting. A qualitative descriptive phenomenological study was conducted in 2020. Data were collected through semi-structured interviews and written narratives from 36 nursing professionals working in the Riojan Health Service. Three main themes emerged: perceived emotions, stressors, and coping strategies. Nurses reported intense feelings of fear, uncertainty, and frustration, which negatively impacted their mental health and hindered emotional regulation and decision-making. Key stressors included high workload, lack of resources, constant exposure to risk, and rapidly changing clinical situations. Despite these challenges, participants described various coping strategies, such as peer support, professional commitment, and adaptive emotional responses, which helped them manage the situation. The findings describe the emotional impact experienced by nursing professionals during the first months of the COVID-19 pandemic and identify coping strategies used in a specific regional healthcare context in Spain.

Background: The digital divide constitutes a growing form of social inequality, influencing access to, use of, and benefit from digital health technologies. Accurate assessment of this phenomenon requires psychometrically sound measurement instruments, especially in health care contexts. Objective: This systematic review aimed to identify and evaluate the psychometric properties of instruments developed to measure the digital divide, with a particular focus on their application in health-related settings. Methods: A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 and COSMIN (Consensus-Based Standards for the Selection of Health Measurement Instruments) guidelines. Literature searches were performed in PubMed, Scopus, Dialnet, and Web of Science for studies published between 2015 and 2025. Inclusion criteria required studies to report a psychometric evaluation of instruments measuring the digital divide. Results: Four studies met the inclusion criteria (ranging from 875 to 1337 participants). The identified scales primarily measured digital skills and capital. All studies reported adequate internal consistency, with Cronbach α coefficients ranging from 0.70 to 0.94. Structural validity was confirmed through factor analysis in all studies. However, data on temporal stability and responsiveness were absent. Conclusions: Existing instruments show potential for assessing digital inequality in health, but further psychometric validation and cultural adaptation are required. Nursing professionals are encouraged to lead efforts in developing and validating context-sensitive instruments to promote digital health equity.

Background: Pregnancy is a period of major brain adaptation, involving structural and functional changes that help women adjust to motherhood and support caregiving. Objective: To review current evidence on neuroplasticity during pregnancy and the postpartum period, focusing on brain changes, their biological basis, and their relevance for maternal mental health and nursing care. Methods: A systematic review with narrative synthesis was conducted in accordance with the PRISMA 2020 statement. The protocol was prospectively registered in PROSPERO (CRD420261376422). Searches were performed in PubMed, BVS, IBECS, CINAHL, and the Cochrane Library for studies published between 2016 and 2026 in English or Spanish. Results: Of the 1722 records initially identified, 15 studies were included in the narrative synthesis after screening and quality assessment using the CASP checklists and SANRA scale. The evidence showed that pregnancy is associated with changes in grey and white matter, as well as in brain connectivity, particularly in regions involved in social cognition, emotional regulation, and maternal behavior. These changes, largely driven by hormonal fluctuations, may persist after childbirth and are associated with greater maternal sensitivity, stronger mother–infant bonding, and more effective caregiving. However, they may also increase vulnerability to perinatal mental health disorders. Conclusions: Pregnancy represents a critical period of neuroplasticity. A better understanding of these changes may improve perinatal care, support maternal mental health, and guide nursing interventions during the transition to motherhood.
