STUDY OBJECTIVES: We sought to
evaluate the construct validity and factor structure of the Spanish-language
version of the Pittsburgh Sleep Quality Index (PSQI) among pregnant Peruvian
women. METHODS: A cohort of 642 women were interviewed at ≤ 16 weeks of
gestation. During interview, we ascertained information about lifestyles,
demographics, sleep characteristics, and mood symptoms. Stress induced sleep
disturbance, depressive symptoms, and anxiety symptoms were evaluated using the
Ford Insomnia Response to Stress Test (FIRST), Patient Health Questionnaire-9
(PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) assessment scales,
respectively. Consistency indices, exploratory and confirmatory factor analyses,
correlations, and logistic regressions were used. RESULTS: Both exploratory and
confirmatory factor analyses indicated a three-factor solution: sleep quality,
sleep efficiency, and sleep medication. We observed significantly positive
correlations of the PSQI with the FIRST (0.42), the PHQ-9 (0.49), and the GAD-7
(0.46). Poor sleepers (PSQI global score > 5) had significantly increased
odds of experiencing stress-induced sleep disturbance (odds ratio, OR = 3.57;
95% CI: 2.40, 5.31), depression (OR = 5.48; 95% CI: 3.58, 8.37), and
generalized anxiety disorder (OR = 4.57; 95% CI: 3.08, 6.76). CONCLUSION: The
Spanish-language version of the PSQI instrument was found to have good
construct validity among pregnant Peruvian women. Consistent with some other
studies, the PSQI was found to have a three-factor structure. Further
assessment and validation studies are needed to determine whether the three,
factor-specific scoring of the PSQI is favored over the PSQI global score in
diverse populations.
