Araújo, Lia; Ayala, Alba; Calderón-larranaga, Amaia; Fernández-Mayoralas, Gloria; Forjaz, Maria Joao; Ribeiro, Oscar; rodríguez-blázquez, Carmen; rojo-Pérez, Fermina; Teixeira, LaetitiaA melhoria das condições de vida e os avanços da medicina permitiram um aumento considerável da esperança de vida e, como consequência, um expressivo envelhecimento da população. em Portugal, as pessoas com 65 e mais anos representam hoje 22.3% da população residente, e prevê-se que este valor aumente significativamente nos próximos anos. enfrentar esta realidade demográfica é um dos principais desafios da sociedade. um dos desafios mais relevantes é a gestão do que já se designou de “epidemia da solidão”, ou seja, o impacto negativo que a solidão não desejada e o isolamento social têm na saúde mental e na qualidade de vida dos mais velhos. em Portugal, estudos comunitários indicam que entre 14% e 36% das pessoas com 65 e mais anos refere sentir sentimentos de solidão, e que cerca de 27% apresenta distress psicológico. a evidência científica dá-nos conta, também, que a abordagem a estas problemáticas deve considerar intervenções multidisciplinares e multidimensionais, sustentadas por recursos institucionais e comunitários apropriados, já que as mesmas têm um impacto positivo na qualidade de vida e na saúde mental das pessoas mais velhas. a solidão e os problemas de saúde mental requerem medidas urgentes destinadas à promoção da saúde e da qualidade de vida. este documento apresenta um conjunto de recomendações baseadas no Projeto QASP – quality of life and aging in spain, sweden and Portugal.
- Influence of Active and Healthy Ageing on Quality of Life Changes: Insights from the Comparison of Three European CountriesPublication . Ayala, Alba; Rodríguez-Blázquez, Carmen; Calderón-Larrañaga, Amaia; Beridze, Giorgi; Teixeira, Laetitia; Araújo, Lia; Rojo-Pérez, Fermina; Fernández-Mayoralas, Gloria; Rodríguez-Rodríguez, Vicente; Quirós-González, Víctor; Zorrilla-Muñoz, Vanessa; Agulló-Tomás, María Silveria; Ribeiro, Oscar; Forjaz, Maria JoãoThis study aimed to analyze the determinants of quality of life (QoL) in older people in three European countries (Portugal, Spain and Sweden). A sample of 7589 participants in waves 4 (2011) and 6 (2015) of the Survey on Health, Aging, and Retirement in Europe (SHARE) project, aged 50 and over and living in Portugal, Spain and Sweden, was included. The CASP-12 scale was used to measure QoL. A principal component analysis was performed to group preselected variables related to active and healthy ageing into the dimensions of health, social participation, and lifelong learning. A linear regression model was built using the change in CASP-12 scores over the 4-year follow-up as the dependent variable, including the interactions between country and each independent variable in the model. After four years, the average QoL increased in Portugal (difference = 0.8, p < 0.001), decreased in Spain (-0.8, p < 0.001), and remained constant in Sweden (0.1, p = 0.408). A significant country-participation component interaction (p = 0.039) was found. In Spain, a higher participation (β = 0.031, p = 0.002) was related to a higher QoL improvement at 4 years, but not in Sweden or Portugal. Physical health and emotional components (β = 0.099, p < 0.001), functional ability (β = 0.044, p = 0.023), and cognitive and sensory ability (β = 0.021, p = 0.026) were associated with QoL changes over time in all countries. The country-specific associations between health, social participation and QoL should be taken into account when developing public health policies to promote QoL among European older people.
- Psychometric Properties of the CASP-12 Scale in Portugal: An Analysis Using SHARE DataPublication . Rodríguez-Blázquez, Carmen; Ribeiro, Oscar; Ayala, Alba; Teixeira, Laetitia; Araújo, Lia; Forjaz, Maria JoãoThe purpose of this study is to assess the psychometric properties of the Portuguese version of the Control, Autonomy, Self-realization, and Pleasure (CASP)-12 scale used in the Survey of Health, Aging and Retirement in Europe (SHARE) project. Data were obtained from a representative sample of 1666 people aged ≥50 years living in Portugal and participating in the SHARE wave 6. In addition to the CASP-12 scale, sociodemographic data and health status, activity limitation (GALI), depression (Euro-D) and satisfaction with life scores were collected. Data quality and acceptability, construct and structural validity and internal consistency of the CASP-12 scale were analyzed. A Rasch analysis was also performed. CASP-12 total score (mean: 33.3; standard deviation: 5.8, range: 12–48) correlated with Euro-D (−0.57) and with life satisfaction (0.52). Mean scores were significantly lower for women, people aged ≥75 years and those with activity limitations and worse health status (p < 0.001). The confirmatory factor analysis showed good fit to the 4-factor model (root mean squared error of approximation (RMSEA): 0.07; comparative fit index (CFI): 0.90, χ2 (48) = 444.59, p < 0.001), which was confirmed by Rasch analysis (χ2 (36) = 10.089, p = 0.745, person separation index (PSI) = 0.722 for the 4-factor model). For domains, person separation index ranged 0.31–0.79 and Cronbach’s alpha, 0.37–0.73. In conclusion, the Portuguese version of the CASP-12 scale presents some inadequacies in acceptability, internal consistency and structural validity.
