O aumento significativo da esperan?a m?dia de vida e o consequente aumento da popula??o envelhecida acentua a necessidade do recurso a m?todos fi?veis e v?lidos na avalia??o desta popula??o. Assim, a presente investiga??o tem como objetivo principal a adapta??o e valida??o da prova Positive and Negative Affect Schedule (PANAS; Watson, Clark e Tellegen, 1988) e a Satisfaction With Life Scale (SWLS, Diener, Emmons, Larsen e Griffin, 1985). S?o medidas de rastreio breve. A PANAS, constitu?da por 22 itens, destina-se a avaliar a afetividade e a SWLS, composta por cinco itens, pretende avaliar a satisfa??o com a vida e ambas medem o bem-estar subjetivo. O processo de adapta??o e valida??o das provas consistiu na administra??o de um protocolo de avalia??o a uma amostra de 555 idosos institucionalizados, entre os 65 e os 100 anos de idade (M ? DP = 80,7 ? 6,7). As an?lises revelam uma diminui??o significativa dos afetos positivos com a idade. As outras medidas n?o se alteraram com a idade. A PANAS revela uma consist?ncia interna adequada (? = 0,75), incluindo a dimens?o dos afetos positivos (? = 0,79) e negativos (? = 0,84). Os resultados da an?lise fatorial suportam a exist?ncia de dois fatores. A consist?ncia interna da escala SWLS ? tamb?m ela adequada (? = 0,76). A an?lise fatorial confirma a exist?ncia de um s? fator para esta escala. A estabilidade temporal teste-reteste foi calculada demonstrando a estabilidade da escala SWLS no intervalo de um ano. A PANAS n?o se revelou est?vel no mesmo intervalo. O estudo das inter-correla??es evidencia a associa??o negativa entre PANAS negativo e a SWLS e uma associa??o positiva entre PANAS positivo e SWLS. A associa??o entre as duas dimens?es da PANAS ? significativa e negativa. Estes resultados s?o semelhantes aos encontrados em outros estudos com a PANAS e SWLS: noutros tipos de popula??o. S?o instrumentos confi?veis e v?lidos como instrumentos de avalia??o para serem usados com a popula??o idosa institucionalizada. / The significant increase in life expectancy and the consequent increase in the aging population highlight the need to use reliable and valid methods in the evaluation of this population. Thus, the present investigation has as its main objective the adaptation and validation of Positive and Negative Affect Schedule (PANAS, Watson, Clark & Tellegen, 1988) and the Satisfaction With Life Scale (SWLS, Diener, Emmons, Larsen & Griffin, 1985). They are screening measures. PANAS consists of 22 items, designed to assess the affectivity, and SWLS, consisting of five items, to evaluate the satisfaction with life, both measuring the subjective well-being. The adaptation and validation consisted in the administration of an assessment protocol to a sample of 555 institutionalized elderly between 65 and 100 years. Analyzes revealed a significant decrease in positive affect with age, the others measures did not suffer any change with age. PANAS revealed an adequate internal consistency (? = 0.75), including the dimension of positive affect (? = 0.79), and negative affect (? = 0.84). The results of the factorial analysis support the existence of two factors. The internal consistency of SWLS is also adequate (? = 0.76). The factor analysis confirms the existence of a single factor for this scale. Test-retest reliability was calculated demonstrating that the scale SWLS was stable for one year interval. PANAS scale wasn?t stable for the same lapse of time. The study of inter-correlations shows the negative association between SWLS and PANAS negative and a positive association between positive PANAS and SWLS. The association between both PANAS dimensions is significantly negative. These results are similar to those found in other studies with the PANAS and SWLS: with other population these instruments are reliable and valid evaluation tools for use with the institutionalized.
