A tese desenvolvida tem como foco fornecer os meios necessários para extrair conhecimento contidos no histórico académico da instituição transformando a informação em algo simples e de fácil leitura para qualquer utilizador. Com o progresso da sociedade, as escolas recebem milhares de alunos todos os anos que terão de ser orientados e monitorizados pelos dirigentes das instituições académicas de forma a garantir programas eficientes e adequados para o progresso educacional de todos os alunos. Atribuir a um docente a responsabilidade de actuar segundo o historial académico dos seus alunos não é plausível uma vez que um aluno consegue produzir milhares de registos para análise. O paradigma de mineração de dados na educação surge com a necessidade de otimizar os recursos disponíveis expondo conclusões que não se encontram visiveis sem uma análise acentuada e cuidada. Este paradigma expõe de forma clara e sucinta os dados estatísticos analisados por computador oferecendo a possibilidade de melhorar as lacunas na qualidade de ensino das instituições. Esta dissertação detalha o desenvolvimento de uma ferramente de inteligência de negócio capaz de, através de mineração de dados, analisar e apresentar conclusões pertinentes de forma legível ao utilizador.

Quality of Life Predictors and Normative Data

This study identifies predictors and normative data for quality of life (QOL) in a sample of Portuguese adults from general population. A cross-sectional correlational study was undertaken with two hundred and fifty-five (N = 255) individuals from Portuguese general population (mean age 43 years, range 25–84 years; 148 females, 107 males). Participants completed the European Portuguese version of the World Health Organization Quality of Life short-form instrument and the European Portuguese version of the Center for Epidemiologic Studies Depression Scale. Demographic information was also collected. Portuguese adults reported their QOL as good. The physical, psychological and environmental domains predicted 44 % of the variance of QOL. The strongest predictor was the physical domain and the weakest was social relationships. Age, educational level, socioeconomic status and emotional status were significantly correlated with QOL and explained 25 % of the variance of QOL. The strongest predictor of QOL was emotional status followed by education and age. QOL was significantly different according to: marital status; living place (mainland or islands); type of cohabitants; occupation; health. The sample of adults from general Portuguese population reported high levels of QOL. The life domain that better explained QOL was the physical domain. Among other variables, emotional status best predicted QOL. Further variables influenced overall QOL. These findings inform our understanding on adults from Portuguese general population QOL and can be helpful for researchers and practitioners using this assessment tool to compare their results with normative data

Purpose: Identify predictors and normative data for quality of life (QOL) in a sample of Portuguese adults from general population Methods: A cross-sectional correlational study was undertaken with two hundred and fifty-five (N=255) individuals from Portuguese general population (mean age 43yrs, range 25-84yrs; 148 females, 107 males). Participants completed the European Portuguese version of the World Health Organization Quality of Life short-form instrument (WHOQOL-Bref) and the European Portuguese version of the Center for Epidemiologic Studies Depression Scale (CES-D). Demographic information was also collected. Results: Portuguese adults reported their QOL as good. The physical, psychological and environmental domains predicted 44% of the variance of QOL. The strongest predictor was the physical domain and the weakest was social relationships. Age, educational level, socioeconomic status and emotional status were significantly correlated with QOL and explained 25% of the variance of QOL. The strongest predictor of QOL was emotional status followed by education and age.

Conclusions: The sample of adults from general Portuguese population reported high levels of QOL. The life domain that better explained QOL was the physical domain. Among other variables, emotional status best predicted QOL. Further variables influenced overall QOL. These findings inform our understanding on adults from Portuguese general population QOL
