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.

It has been acknowledged that the pedestrian environment in downtown Pittsburgh is inadequate, lacking connectivity and significant amounts of quality open space, and as a transportation system it is in direct conflict with vehicular traffic. This creative project examines the condition of the pedestrian environment relative to the other systems, places, and activities that are affected by pedestrian welfare. The intense activity within the CBD generates volumes of pedestrian and vehicular traffic that it can hardly support. The pedestrian environment lacks sufficient space, and, as a result, the pedestrian's mobility is constricted and there is excessive conflict with vehicles. Moreover, pedestrians in downtown Pittsburgh have very few opportunities to access the waterfront and spaces and buildings of particular significance within and adjacent to the CBD.The design solutions that are proposed herein include a variety of development guidelines, street adaptations and open space recommendations. Through the installation of these solutions the pedestrian environment becomes enhanced and downtown Pittsburgh is able to become a more cohesive place where history, architecture and nature are integrated into an urban environment that is truly livable. / Department of Landscape Architecture
