Translation and cross-cultural adaptation into Spanish of the Rapid Clinical Assessment of Modes Mario Arnaiz González Irene Pérez-Díaz Estíbaliz Jiménez Arberas Spanish translation cross-cultural adaptation therapeutic relationship use of self occupational therapy therapeutic communication construct validity inter-rater reliability observer perspective Introduction: The therapeutic relationship and the use of self are essential components of Occupational Therapy practice, yet few validated instruments assess these constructs across therapist, client, and observer perspectives, particularly in Spanish-speaking contexts. This study aimed to translate and culturally adapt the Rapid Clinical Assessment of Modes into Spanish and to examine its preliminary psychometric properties. Method: The translation and adaptation process followed standardized guidelines, including forward–backward translation, expert panel review, and iterative revision. The Spanish Rapid Clinical Assessment of Modes was administered to 41 clients receiving occupational therapy, 6 therapists, and 7 observers. Construct validity was evaluated using exploratory factor analysis with Unweighted Least Squares estimation. Inter-version relationships were examined using Spearman correlations, Bland–Altman analyses, and Krippendorff’s alpha. Results: No missing data were observed in the Rapid Clinical Assessment of Modes item responses used for psychometric analyses. Sampling adequacy was good (KMO = 0.79–0.82; Bartlett’s test p < 0.001). Parallel analysis supported a unidimensional structure for all three versions, jointly explaining 51%–61% of variance. Moderate to strong correlations were found among versions ( r = 0.48–0.65, p < 0.01). Agreement between raters was substantial (Krippendorff’s α = 0.74). Conclusion: The Spanish Rapid Clinical Assessment of Modes provided preliminary evidence of structural validity, reliability, and cross-perspective consistency, suggesting its potential utility as a brief tool to assess therapeutic communication and the use of self in Occupational Therapy. 2026 en info:eu-repo/semantics/article journal-article https://doi.org/10.1177/03080226261484047 British Journal of Occupational Therapy British Journal of Occupational Therapy urn:issn:0308-0226 urn:issn:1477-6006 British Journal of Occupational Therapy, 2026 info:eu-repo/semantics/openAccess openAccess https://journals.sagepub.com/doi/pdf/10.1177/03080226261484047?download=true Q2 Good health and well-being Instituto Universitario de Investigación Padre Ossó https://www.facultadpadreosso.es/investigacion/portal Effects of an mHealth Occupational Therapy Intervention on Functional Performance: A Pilot Study Irene Pérez-Díaz Mario Arnáiz-González Estíbaliz Jiménez Arberas mobile health occupational therapy neurodevelopmental disorders children activities of daily living telerehabilitation mobile health apps app usability family-centered care functional performance PEDI-CAT Neurodevelopmental disorders are one of the most prevalent conditions today, and among the limitations in activity and restrictions in the participation of children and their families, we find intervention in activities of daily living; therefore, research focused on outcome measurement is one of the most active lines, and after COVID-19, telerehabilitation has garnered special interest. BACKGROUND/OBJECTIVES: The study objective was to evaluate the effectiveness of a mobile health (mHealth) application in improving the performance of activities of daily living in children with neurodevelopmental disorders. METHODS: The study employed a quasi-experimental design with a control group, using a fully remote mHealth-based intervention. The instruments used were a sociodemographic ad hoc, Pediatric Evaluation of Disability Inventory Computer, Family Outcomes Survey, Family Confidence Scale, and System Usability Scale. The final sample consisted of 13 participants. RESULTS: The mHealth intervention showed significant improvements in occupational performance in the experimental group, especially in the global score and in the Responsibility dimension of the PEDI-CAT. No relevant differences were observed in the CON-FAN and FOS scales between groups, although the latter showed improvements over time. The usability of the app was rated positively (SUS = 69.75). CONCLUSIONS: The developed application presents good usability for families of children with neurodevelopmental disorders, but to obtain better outcome measures, the intervention should combine face-to-face sessions and the use of mHealth, as well as employing the family-centered model. 2025 en info:eu-repo/semantics/article journal-article https://doi.org/10.3390/healthcare13162015 Healthcare Healthcare urn:issn:2227-9032 Healthcare, 2025, vol. 13, n. 16, p. 2015 info:eu-repo/semantics/openAccess openAccess cc-by https://www.mdpi.com/2227-9032/13/16/2015/pdf?version=1755259629 Q1 pubmed Good health and well-being Instituto Universitario de Investigación Padre Ossó https://www.facultadpadreosso.es/investigacion/portal INFORME SOBRE EXCLUSIÓN Y DESARROLLO SOCIAL EN ASTURIAS 2025 info:eu-repo/semantics/book book cris:cris-d0926771 FUNDACIÓN FOESSA FUNDACIÓN FOESSA FUNDACIÓN FOESSA, 2025 Instituto Universitario de Investigación Padre Ossó https://www.facultadpadreosso.es/investigacion/portal
