- Confirmatory Factor Analysis of Sleep Model’s QuestionnairesPublication . Pinto, Teresa Rebelo; Pinto, Joana Carneiro; Pinto, Helena Rebelo; Brito, Filipa; Paiva, TeresaObjectives: The present study aims to test the factor structure of two sleep questionnaires and their internal consistency in a sample of adolescents and their respective parents and to evaluate the validity and robustness of a three-dimensional model about sleep, addressing nine subcategories related to sleep habits, personal and environmental factors (Rebelo-Pinto, Pinto, Rebelo-Pinto, & Paiva, 2014). Methods: Participants were 654 adolescents from Portuguese schools, who completed “My Sleep and I” questionnaire, and 664 parents who completed “My child’s sleep” questionnaire; to them confirmatory factor analysis was applied. Results: Confirmatory factor analysis indicate that a nine-factor model has better fit indices compared with the others tested models for both samples (Adolescents: X2/df (chi-square/degrees of freedom)= 2.59, CFI (Comparative Fit Index)=.82, GFI (Goodness-of-Fit Index)=.92, RMSEA (Root Mean Square Error of Approximation)=.049, ECVI (Expected Cross-Validation Index)= 1.416; Parents: X2/df= 2.89, CFI=.85, GFI=.91, RMSEA=.053, ECVI= 1.528). Moreover, the comparison of the models through Δχ² index (chi-square difference between rival models) indicates a better fit for this model, Δχ² (24) = 186.5, p < .001 for adolescents and Δχ² (24) = 209, p < .001 for parents. Also, the three second-order factors have good internal consistency, convergent and discriminant validity for all factors in both samples. Conclusions: Results postulate that the three factors and their nine subcategories account for correlations between sleep habits, self-perceptions and knowledge about sleep.
- Evaluation of two projects on Sleep Education: “Sleep Schools Project” and “Sleep more to Read better”Publication . Pinto, Teresa Rebelo; Pinto, Joana Carneiro; Pinto, Helena Rebelo; Brito, Filipa; Cravo, Filomena; Luís, Paula; Paiva, TeresaObjectives: The present work aims to present the activities of sleep education and sleep awareness, whenever an educational model is assumed: a three-dimensional model about sleep, addressing sleep habits, personal and environmental factors with nine subcategories, together with the associated community projects around sleep and scientific research activities. Two projects are evaluated: Sleep Schools Project (SSP) and Sleep more to Read better (SMRB) Methods: In spite of somewhat different objectives both projects used similar methodologies and therefore are evaluated together. The program was developed in public and private Portuguese schools, from “kindergarden” to Secondary school???. The observation period is 5 years. The number of educational and awareness actions was computed along project evolution and trends measured. Idem for community projects around sleep, research presentations, education materials and media dissemination (direct and indirect impacts). Besides, a quantitative evaluation of the territorial areas covered and the number of target subjects involved was done. Furthermore the accuracy and efficiency of the model was assessed. Chi square, regression and trend analysis were applied. Results: The attendants, and project targets, were teachers, parents, students, health professionals. The number of sessions performed from 2009 to 2014 increased exponentially. ??? The same holds for the number of attendants and visited schools???. The total number of scientific communications was 37; while … questionnaires and 1 model were validated. The number of community projects also increased and is presently …. The number of communication in the media (TV, radio and news papers also increased significantly. The territorial distribution shows a higher density of actions in the littoral regions with significantly lower values in the interior and southern regions. Conclusions: The present data are clear indicators of significant awareness raising, but future work must deal with measurement of impacts upon children/ adolescents sleep behaviors
