In Brazil, a country of continental size, this process began in the 40s and happens with specific features in each of the different region s realities. This way, this thesis aimed to evaluate the psychometric properties of a elderly s quality of life (QOL) scale, the WHOQOL-old, in a population of the Northeast of Brazil. We sought to investigate the congruence between the content covered by the scale and the ones deemed as relevant by the participants. It aimed also study the validity evidences of the instrument s internal structure. To achieve the research objectives we adopted the design of multiple methods. The research was organized in two studies. For data collection, both studies used a sociodemographic questionnaire to obtain a profile of the participants and the Mini Mental State Exam (MMSE), used as exclusion criterion. A number of 18 elderly residents of the cities of Natal-RN and Campina Grande-PB, mean age of 73.3 years (SD = 5.9) took part od the study, They were organized into three focal groups (FG) in witch they discussed about the concept of QOL, what enhance and what hinders QOL. For Study II, a quantitative approach, 335 elderly from Campina Grande responded scale WHOQOL-old. They are between 65 and 99 years (M = 74.17, SD = 6.5). The FG data were analyzed by categorical thematic content. For the data analysis of the WHOQOL-old scale were used exploratory factor analysis and calculation of the Akaike and Bayesian information criteria. The results of both studies were triangulated. According to the discussions in the FG, health and social participation have central roles in quality of life. Social participation is related to all the other QOL s influences raised. The participants indicated the relevance of religiosity and were divided about the importance of sexual activity. Exploratory factor analysis (EFA) extracted a model of six factors. Two items (OLD_3 and OLD_9), not loaded on any factor and were excluded. The other items had factor loadings > 0.3. The response categories were reduced from five to three. After the scale changes, the empirical model showed better fit (-2loglikelihood = 8993.90, BIC and AIC = 9183.90 = 9546.24) than the theoretical model (-2loglikelihood = 18390.88, AIC = 18678.88 and BIC = 19228.11). Despite the best information criterion values, the RMESA remained above the ideal (0.06). We conclude that the WHOQOL-old presents psychometric parameters below the ideal when used with the Northeast population, but the improvements made the scale s use acceptable. The WHOQOL-old uses observable variables that matches with the participants' perceptions on quality of life. However, new strategies must be tested for a better sacale refinement / O envelhecimento populacional aumenta o n?mero de idosos em todo mundo. No Brasil, pa?s de tamanho continental, esse processo come?ou na d?cada de 40 e acontece com caracter?sticas espec?ficas em suas diferentes realidades. Dentro dessa perspectiva, a presente disserta??o teve o objetivo de avaliar as propriedades psicom?tricas da escala de avalia??o da qualidade de vida (QV) de idosos, WHOQOL-old, em uma popula??o de nordestinos. Buscou-se investigar a congru?ncia entre os conte?dos abordados pela escala e aqueles considerados relevantes pelos participantes; e estudar as evid?ncias de validade de estrutura interna do instrumento. Para atingir os objetivos da pesquisa foi adotado o desenho de m?todos m?ltiplos. A pesquisa foi organizada em dois estudos. Como instrumento de coleta de dados comum a ambos, foi utilizado question?rio sociodemogr?fico para tra?ar o perfil dos participantes e o Mini Exame do Estado Mental (MEEM), que serviu como crit?rio de exclus?o. O Estudo I, de abordagem qualitativa, contou com a participa??o de 18 idosos moradores das cidades de Natal-RN e Campina Grande-PB, m?dia de idade de 73,3 anos (DP = 5,9), divididos em tr?s grupos focais (GF) que discutiram o conceito de QV, o que ajuda e o que atrapalha a QV. Para o estudo II, de abordagem quantitativa, 335 idosos de Campina Grande, entre 65 e 99 anos (M = 74,17; DP = 6,5) responderam a escala WHOQOL-old. Os dados dos GF foram submetidos ? an?lise categorial tem?tica de conte?do; e para an?lise dos dados da escala WHOQOL-old foram utilizados an?lise fatorial explorat?ria e c?lculo dos crit?rios de informa??o de Akaike e Bayesiana. Os resultados dos dois estudos foram triangulados. De acordo com as discuss?es nos GF, sa?de e participa??o social t?m pap?is centrais na qualidade de vida. A ?ltima estabelece rela??o com todos os demais temas suscitados. Os participantes indicam a relev?ncia da religiosidade e ficam divididos sobre a import?ncia da atividade sexual. Analise fatorial explorat?ria (EFA) extraiu um modelo de seis fatores. Dois itens (OLD_3 e OLD_9), n?o carregaram em nenhum fator e foram exclu?dos. Os demais itens apresentaram carga fatorial >0,3. As categorias de resposta foram reduzidas de cinco para tr?s. Ap?s as mudan?as na escala, o modelo emp?rico apresentou melhor ajuste (- 2loglikelihood = 8993,90; AIC = 9183,90 e BIC = 9546,24) que o modelo te?rico (- 2loglikelihood = 18390,88; AIC = 18678,88 e BIC = 19228,11). Apesar dos melhores valores de crit?rio de informa??o, o RMESA permaneceu acima do ideal (0,06). Conclui-se que o WHOQOL-old apresenta par?metros psicom?tricos abaixo do ideal na popula??o nordestina, mas as melhorias o tornaram sua utiliza??o aceit?vel. O instrumento WHOQOL-old utiliza vari?veis observ?veis que condizem com a percep??o dos participantes sobre qualidade de vida. No entanto, novas estrat?gias merecem ser testadas para refinamento da escala
