Avaliação da dependência de Internet e qualidade de vida em adolescentes Brasileiros de escolas públicas e particulares

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Este trabalho avaliou o perfil de estudantes em relação ao padrão de uso de Internet e qualidade de vida, tomando como sujeitos de pesquisa alunos do ensino médio (N = 254, M_idade = 15,1, DP = 1,3) de escolas públicas e particulares da cidade de São Paulo. Utilizou-se o Teste de Dependência em Internet e o Pediatric Quality of Life Inventory. Aproximadamente 70% dos estudantes apresentaram dependência média de Internet. Estudantes de escola pública apresentaram maiores níveis de dependência grave em relação aos da escola particular (p < 0,001). Em relação à qualidade de vida, estudantes da escola particular apresentaram melhores indicadores no aspecto social (p < 0,01), enquanto aqueles da escola pública apresentaram melhores indicadores no aspecto escolar (p < 0,05). Os dados indicaram uma forte associação entre dependência de Internet e menores indicadores de qualidade de vida, conforme observado em estudos de outros países.

What are the advantages of a virtual conversation as opposed to face-to-face^a a Descriptive levels of Chi-square or Fisher’s exact test for multiple choice responses. Public school (n = 159), Private school (n = 95). The effect size (Cramer’s V Test) was based on the following degrees of freedom: df = 1 (0 to 0.1 = small effect); (0.11 to 0.3 = medium effect); (0.31 to 1, high effect); df = 2 (0 to 0.07 = small effect); (0.08 to 0.21 = medium effect); (0.22 to 1, high effect). df = 3 (0 to 0.06 = small effect) (0.07 to 0.17 = medium effect) (0.18 to 1.0, high effect); df = 4 (0 to 0.05 = small effect) (0.06 to 0.13 = medium effect) (0.14 to 1.0, high effect).
