Abstract

Objective: To develop and verify the validity, reliability and interpretability of an assessment instrument of the Health Literacy regarding Diabetic Foot (HLDF).

Method: Methodological study among people with diabetes enrolled in Family Health Strategy (FHS) program, composed of eight phases: selection of participants; development of LSPD; verification of content validity by the committee of experts; pre-test (n=20); reliability estimation (n=62): Cronbach's alpha (CA), Kappa (K) and Intraclass Correlation Coefficient (ICC), satisfactory results (≥0.60); estimation of concurrent validity (n=62); interpretability of scores: range from 0-18, if ≤14 HLDF inadequate; hypothesis test (multiple logistic regression): OR/IC95% in a sample estimated for infinite population, using SPSS.

Results: The HLDF has adequate and fast application, being relevant as to its content and to the construct that proposes to evaluate. About the reliability CA=0.73, two items presented Kappa<0.60, ICC=0.79. About the concurrent validity, there was correlation between the HLDF and schooling (rs=0.647; p=0.000). Interpretability: 50.2% (n=112) presented inadequate HLDF. The younger ones presented lower levels of inadequate HLDF (0.96/0.93-0.99); as to those with lower scholarship (1.15/1.06-1.25) and lower family income (1.01/1.00-1.01) presented higher levels of inadequate HLDF.

Conclusion and implications for practice: The HLDF was considered as valid, reliable and interpretable. The HLDF can identify people with more effective educational strategies needs.

Resumen

Objetivo: Desarrollar y verificar la validad, fiabilidad e interpretabilidad de un instrumento de evaluación que propone evaluar la Literacia en Salud en lo que concierne al Pie Diabético (LSPD).

Método: Estudio metodológico entre personas con diabetes catastradas en Estrategias de Salud de la Familia, compuesto por ocho fases: selección de los participantes; desarrollo del LSPD; verificación de validad del contenido por el comité de expertos; pre-test (n=20); estimación de la confiabilidad (n=62); Alfa de Cronbach (AC), Kappa y Coeficiente de Correlación Intraclase (CCI); resultados satisfactorios (≥0,60); estimación de la validez concurrente (n=62); interpretabilidad de los scores: varían de 0-18 se ≥14 LSPD adecuado; prueba de hipótesis (regresión logística múltiple): OR/IC95% en una muestra estimada para población infinita, utilizando el SPSS.

Resultados: El LSPD tiene una aplicación adecuada y rápida, siendo relevante en relación con su contenido y al constructo que propone evaluar; en relación con su confiabilidad AC=0,73; dos de los elementos presentaron Kappa<0,60; CCI=0,79. En cuanto a la validez concurrente, hubo correlación del LSPD con la escolaridad (rs=0,647; p=0,000). Interpretabilidad: 50,2% (n=112) presentaron LSPD inadecuada. Los más jóvenes presentaron niveles más bajos de LSPD inadecuada (0,96/0,93-0,99); ya aquellos con menor nivel de educación (1,15/1,06-1,25) y menor renda familiar (1,01/1,00-1,01) presentaron niveles más altos de LSPD inadecuada.

Conclusión e Implicaciones para la práctica: El LSPD fue considerado válido, confiable e interpretable. El LSPD podrá identificar personas con necesidades de estrategias educativas más efectivas.
