Development and Psychometric Testing of Scales of Knowledge, Attitude, and Practice of Self-Care for Patients With Arteriovenous Fistula.

Background and Purpose: To validate the scales of knowledge, attitude, and practice of self-care for arteriovenous fistulas in renal patients on hemodialysis. Methods: A methodological study verified the evidence of validity based on the content, response processes, and internal structure of the scales. The content was evaluated by six judges, and the response processes were verified with six patients. In the evaluation of the internal structure, the scales were applied to 220 patients for exploratory factor analysis with evaluation of McDonald's omega adjustment and calculation indexes. Results: The scales explained variance and McDonald's omega values of 40.4%/0.896, 60.7%/0.843, and 36.9%/0.702 for the knowledge (19 items), attitude (4 items), and practice (8 items), respectively. Conclusions: The scale of attitude was valid after the analysis of the content evidence, response processes, and internal structure. The arteriovenous fistula self-care knowledge and practice scales explained less than 50% of the constructs. Therefore, it is recommended that new studies be conducted to validate scales of knowledge and practice of fistula self-care.

Construction and validation of content of a video on self-care with arteriovenous fistula. / Construcción y validación del contenido de un video acerca del autocuidado de la fístula arteriovenosa.

OBJECTIVE: To validate the content of the script of an educational video to promote self-care with arteriovenous fistula in chronic renal patients with nurses and social communicators. METHOD: Methodological study that constructed and validated an educational video. Firstly, the demands of self-care were identified through a literature review on self-care with arteriovenous fistula. Then the construction of the video followed the steps of pre-production, production and post-production. The script's content validation occurred in the pre-production phase and counted on 22 nursing judges and media professionals. The study was approved by the Ethics Committee in Research, under opinion 61705516.0.0000.5208. RESULTS: The following items received a negative evaluation from the judges: "The scenes described reflect stereotypes or discrimination" (p = 0.008) and "The pace of the scenes is tiring" (p = 0.001/p = 0.034), "The characters/images are appealing to the audience (p = 0.006), "The illustrations reflect important aspects of subject under study" (p = 0.006), "The illustrations promote the understanding of the video message" (p = 0.001) and "The general structure is creative" (p = 0.001). CONCLUSION: The educational video was considered valid by the nursing judges and media professionals to promote self-care with arteriovenous fistula among renal patients.
