Abstract
Objective: to assess the validity and reliability of the UCLA Loneliness Scale, version 3, in a sample of aged Brazilians.
Methods: a methodological study carried out with 136 older adults registered in family health units. Construct validity was verified by exploratory factor analysis and correlation with depression and social support measures. Reliability was assessed by means of Cronbach's alpha.
Results: in the exploratory factor analysis, a component was extracted, whose variance explained 43.6% of the instrument's composition. All items had a satisfactory factor load (≥ 0.30) distributed between 0.43 and 0.76. Construct validity was also supported by the positive correlation between loneliness and depression (r = 0.665; p≤0.001) and a negative correlation between loneliness and social support (r = -0.576; p≤0.001). It was also supported by the positive correlation between loneliness and depression (r = 0.665; p≤0.001) and a negative correlation between loneliness and social support (r = -0.576; p≤0.001). Cronbach's alpha for the sample was 0.88.
Conclusion and implications for the practice: the UCLA Loneliness Scale version 3, presents evidence of satisfactory validity and reliability, and can be used to assess loneliness among aged Brazilians.

Resumo
Objetivo: avaliar a validade e a confiabilidade da Escala de Solidão da UCLA versão 3 numa amostra de idosos brasileiros.
Métodos: estudo metodológico, realizado com 136 idosos cadastrados em unidades de saúde da família. A validade de construto foi verificada pela análise fatorial exploratória e correlação com medidas de depressão e apoio social. A confiabilidade foi avaliada pelo alfa de Cronbach.
Resultados: na análise fatorial exploratória foi extraído um componente cuja variância explicou 43,6% da composição do instrumento. Todos os itens apresentaram cargas fatoriais satisfatórias (≥0,30) distribuídas entre 0,43 e 0,76. A validade de construto também foi apoiada pela correlação positiva entre solidão e depressão (r= 0,665; p≤ 0,001) e correlação negativa entre solidão e apoio social (r= -0,576; p≤0,001). O alfa de Cronbach para a amostra foi de 0,88.
Conclusão e implicações para a prática: a Escala de Solidão da UCLA versão 3 apresenta evidências de validade e confiabilidade satisfatórias, podendo ser utilizada para avaliação da solidão entre idosos brasileiros.
