No. of bitstreams: 1 DIS_ANA_BASSOA_DE_MORAES_PARCIAL.pdf: 936438 bytes, checksum: 5d58046075a23b25a285f8af5972b340 (MD5) Previous issue date: 2016-09-29 / Objectives: To develop and collect evidence of validity and reliability for a screening scale for reading and writing skills for children. Methods: 1) review of the literature; 2) evaluation by experts; 3) evaluation by teachers; 4) application of the instrument with 95 students and evaluation of the students with standard reading and writing tests. Data Analysis: We carried out factor analysis, Cronbach alpha r, Rash model, item response theory, Spearman correlation between scale scores and the reading and writing tasks, test-retest reliability coefficient. Results: the main results were (1) development of a 16-item Likert scale for 16 symptoms for reading and writing difficulties; (2) presence of one factor and high factor loads in the factor analysis of the scale; (3) strong internal consistency for the alpha r (0.968), and the item response theory showed greater precision in the evaluation of children with average or low performance; (4) moderate Spearman correlation for 11 of the 16 external variables; (5) temporal stability showed correlation of 0.80. Conclusion: The study shows evidence of validity and reliability for the scale, which indicates the scale is a reliable instrument for teachers and healthcare professionals involved with pediatric patients and interested in investigating language skills. / Objetivo: Construir e obter evid?ncias de validade e fidedignidade para uma escala de rastreio de leitura e escrita para crian?as. M?todo: 1) levantamento bibliogr?fico; 2) avalia??o da escala por ju?zes; 3) avalia??o dos itens por professores; 4) teste da escala com 95 alunos e testagem destes alunos com leitura e escrita. An?lise dos dados: an?lise fatorial; coeficiente alpha de Cronbach; modelo de Rash, pela Teoria de Resposta ao Item (TRI); correla??o de Spearman entre a pontua??o da escala e as tarefas de leitura e escrita; coeficiente de estabilidade para o reteste. Resultados: os principais resultados foram (1) elaborou- se uma escala de 16 itens que mensura a frequ?ncia da manifesta??o de 16 sintomas de dificuldades de leitura e escrita; (2) an?lise fatorial indicou a presen?a de um fator e altas cargas fatoriais na escala; (3) o coeficiente alpha apontou forte consist?ncia interna (0,968) e a an?lise da TRI, para este quesito, indicou maior precis?o na avalia??o de indiv?duos com desempenho m?dio ou baixo; (4) a correla??o de Spearman foi moderada para 11 das 16 vari?veis externas; (5) a estabilidade temporal apresentou valor de correla??o de 0,80. Conclus?o: O estudo mostra evid?ncias de validade e fidedignidade da escala, o que a torna uma ferramenta confi?vel para professores e profissionais envolvidos com pacientes pedi?tricos e preocupados com quest?es de linguagem.
