TLDR
The main criteria and statistical tests used in the assessment of reliability (stability, internal consistency and equivalence) and validity (content, criterion and construct) of instruments are presented, discussed and exemplified.Abstract:
Resumo Instrumentos de medida desempenham um importante papel na pesquisa, na pratica clinica e na avaliacao de saude. Estudos sobre a qualidade desses instrumentos fornecem evidencias de como as propriedades de medida foram avaliadas, auxiliando o pesquisador na escolha da melhor ferramenta para utilizacao. A confiabilidade e a validade sao consideradas as principais propriedades de medida de tais instrumentos. Confiabilidade e a capacidade em reproduzir um resultado de forma consistente, no tempo e no espaco. Validade refere-se a propriedade de um instrumento medir exatamente o que se propoe. Neste artigo sao apresentados, discutidos e exemplificados os principais criterios e testes estatisticos empregados na avaliacao da confiabilidade (estabilidade, consistencia interna e equivalencia) e validade (conteudo, criterio e construto) de instrumentos. A avaliacao das propriedades de medida de instrumentos e util para subsidiar a selecao de instrumentos validos e confiaveis, de modo a assegurar a qualidade dos resultados dos estudos.read more

A Rapid Review of the Measurement of Intrinsic Capacity in Older Adults
TL;DR: The most commonly used tools for assessing intrinsic capacity were gait speed test and chair stand test (locomotion); handgrip-strength and mini-nutritional assessment (vitality); Mini-Mental State Examination (cognition); Geriatric depression scale (GDS) and Center for Epidemiological Studies Depression Scale (CES-D) (psychological), and self-reported vision and health questionnaires (sensory) as mentioned in this paper.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.
