The development and evidence of psychometric properties of the Self-Care Activities Scale focusing on the Daily Life Advanced Activities

Abstract Objective: To develop the Self-Care Activities Scale focusing on the Daily Life Advanced Activities (SCCAS-DLAAs) and to analyze its psychometric properties. Method: This was a methodological, descriptive, and analytical study. The sample consisted of 1200 interviewees of both sexes, aged 70 years or older, residents in cities in southern Minas Gerais state, Brazil. The instruments used were as follows: an instrument to classify the baseline conditioning factors of elderly people, the SCCAS-DLAAs, and the Self-Care Skills Assessment Scale. Results: The SCCAS-DLAAs consisted of 20 items and four domains, namely: Social (α Cronbach = 0.768), Leisure (α Cronbach = 0.643), Intellectual (α Cronbach = 0.708), and Religious (α Cronbach = 0.704). Convergent validity was satisfactory as it showed a positive and significant correlation (p≤0.001). For discriminant validation, the comparative analyses of the sociodemographic variables with the SCCAS-DLAAs were used, presenting a significance level between them, which demonstrated discriminative power. Conclusion: The developed scale showed adequate reliability and validity for the Brazilian context.
