Construcción y validación de la Escala de Evaluación de Trastornos del Sueño en Embarazadas (EETSE)

Abstract

Objective: to construct and validate a scale to assess sleep disorders in pregnant women. Method: cross-sectional study, an instrument was constructed in Spanish with questions aimed at investigating sleep disorders that occur during pregnancy. A pilot test was applied to one hundred pregnant women, randomly selected, who attended the Family Medicine Unit no. 8, in El Marqués, Querétaro, from February to May 2021. The questionnaire was submitted to three rounds of expert judges and a reliability analysis was performed to obtain correlation coefficients. Results: a high degree of intelligibility and relevance per question was determined using Delphi methodology. A confirmatory factor analysis was performed for the correlation between variables with the Bartlett’s Test of Sphericity (p<0.001). A feasible degree of intercorrelation between variables was identified, Kaise-Meyer-Olkin = 0.840. The 20 factors of the instrument were distributed in four principal components that yielded the total variance explained. These items presented factor loading >0.30 and communalities >0.35. The item correlation was found between 0.844 and 0.309. Cronbach’s alpha reliability analysis for internal consistency was 0.927. Conclusion: The Pregnancy Sleep Disorders Assessment Scale fulfills the objective of measuring sleep disorders that occur during pregnancy in Mexican women.
