Abstract
QUEMBA-MESA, Mónica Paola et al. Face validity, reliability and comprehensibility of the main questionnaire used in the PLATINO study, Colombia. Hacia promoc. Salud [online]. 2023, vol.28, n.1, pp.98-116. Epub Nov 02, 2023. ISSN 0121-7577. https://doi.org/10.17151/hpsal.2023.28.1.8.
Introduction:
It is essential to guarantee that the measurement instruments, when used in contexts other than those in which they were developed, adjust in their language and comprehensibility. The main questionnaire used in the PLATINO study was developed to establish the prevalence of Chronic Obstructive Pulmonary Disease in metropolitan areas of Latin America by the Latin American Thorax Association, without including the Colombian population.
Objective:
To perform face validity, reliability and comprehensibility of the main questionnaire used in the PLATINO study for the identification of people without respiratory disease in Colombia, 2021.
Materials and methods:
Psychometric study that included face validity by expert judgment, compressibility and reliability test. The face validity valued the coherence, relevance and pertinence of each item. The application of the instrument was made in a preliminary compressibility test after which its reliability was calculated.
Results:
Face validity obtained high concordance requiring improvements in the writing of the document (Fleiss Kappa: 0,8569; p=0,000). Ofthe 88 participants, the majority were men (n: 75; 85%) with a mean age of 23 years (SD: 6.8), 25% with a history of lung disease and 21% with a history of smoking. The adjusted version of the questionnaire obtained a global comprehensibility of 94% and a Cronbach’s alpha of 0.82.
Conclusions:
An abbreviated and adapted version of the main questionnaire used in the PLATINO study for the identification of respiratory healthy people in the Colombian population was obtained with adequate psychometric properties in terms of its face validity, reliability and comprehensibility.
