RESUMO

A Diabetes Tipo 1 é uma doença crónica complexa e de difícil controlo. Esta dificuldade é mais notória na adolescência, período em que a problemática que envolve a transição da dependência parental para uma vida mais autónoma. A adolescência caracteriza-se também por alterações nas características psicossociais que se podem repercutir na adesão ao tratamento, no controlo metabólico da Diabetes e na qualidade de vida.

O objectivo da presente investigação é adaptar um questionário de avaliação da qualidade de vida para adolescentes.

A amostra que constituiu o presente estudo foi composta por 256 adolescentes, com idades compreendidas entre os dez e os dezoito anos. O diagnóstico foi efectuado pelo menos um ano antes da colheita de dados. A versão portuguesa do DQOL apresenta-se com um número total de itens mais reduzido que a versão original os quais se agrupam em três factores que avaliam o IMPACTO da diabetes na vida actual do adolescente, a SATISFAÇÃO com o tratamento e a vida e a PREOCUPAÇÃO quanto ao futuro. Revela uma consistência interna excelente. A intercorrelação entre as sub-escalas que a compõem é também boa. Duas das subescalas revelam um poder discriminante heterogéneo quanto ao género e nas diversas faixas etárias da adolescência. Por fim apresenta uma elevada validade convergente, correlacionando-se de forma significativa com um questionário de ansiedade face à Diabetes.

Palavras-chave: Qualidade de vida, adolescentes, Diabetes Tipo 1.

 

ABSTRACT

Diabetes Type 1 is a complex chronic disease that is difficult to control specially during adolescence. This is due in part to the developmental transition of adolescence from dependency on parents to a more autonomous lifestyle. Adolescence is also marked by a change in psychosocial characteristics that have an impact on adherence to treatment, metabolic control and quality of life in diabetics.

The purpose of this study is to adapt a questionnaire of quality of life for adolescents with diabetes Type 1. The research included 256 adolescents, aged 10 to 18 years from the Pediatric Department of Hospital S. João – Porto. Diabetes was diagnosed at least a year prior to data collection.

The Portuguese version of DQOL has a smaller number of items than the original version gathered in 3 factors that assess IMPACT of Diabetes in the adolescent day to day life (13 itens), SATISFACTION with treatment and life (17 itens) and WORRY towards the future (6 itens). The scale shows an excellente internal consistency. The intercorrelation between the subscales is also good. The scale is able to descriminate between gender and age according to three phases of adolescence in two of the subscales. It also shows an excellent convergent validity being highly correlated with a questionnaire of anxiety towards diabetes.

Key words: Life quality, adolescents, Diabetes Type 1.
