    Alzheimer’s disease is a type of dementia that progressively affects memory, thinking, and behavior. It can interfere with daily activities and lead to a decline in cognitive abilities over time. Exercise-based interventions can complement Alzheimer’s disease treatment. Exercise is a valuable tool in all healthcare settings and has shown promise as an effective cognitive improvement intervention for people with cognitive impairments. This systematic review and meta-analysis aimed to analyze the effect of physical exercise on the QoL of subjects with Alzheimer’s disease. A search was performed with the help of the electronic databases PubMed and Web of Science. Randomized controlled trials with exercise-based interventions were selected. Four studies met the inclusion criteria, which included interventions based on exercise. The effects were summarized using standardized mean differences (95% confidence intervals) using random-effect models. The results showed that exercise had no significant effect on the QoL of subjects with Alzheimer. Thus, the effect of exercise interventions on the QoL of patients with Alzheimer’s disease is not conclusive. More research is needed about this topic and the way in which the QoL is assessed; the necessity to conduct an objective way to assess the QoL in this population is mandatory.

    Publication . Couto, Nuno; Antunes, Raul; Monteiro, Diogo; MOUTÃO, JOÃO; Marinho, Daniel; Cid, Luis
    The aim of this study is the validation of the Portuguese version of the Basic Need Satisfaction General Scale (BNSG-S) in a sample of Portuguese elderly, and analyze through a structural equations model the effect of the Portuguese elderly individuals’ global perception about the satisfaction of basic psychological needs on subjective well-being. Two samples of Portuguese elderly people aged between 60 and 90 years old were considered in this study. Results revealed that they Model 3 of the BNSG-S (three factors, 11 items) adjusted to the data a (χ² = 103.16, df = 41, SRMR = .05, TLI = .90, CFI = .93, RMSEA = .07, 90% CI = .05-.08). Additionally, structural model analysis, showed a positive and significante ffect between satisfaction of basic psychological needs and subjective well-being. In sum we concluded that the Portuguese version of the BNSG-S can be used as a means to evaluate the satisfaction of the basic psychological needs of the older population and, their satisfaction, has a positive effect on subjective well-being in the Portuguese older population.
  • Physical activity and satisfaction with the life of the elderly: contribution to the validation of the satisfaction with life scale (swls) in the portuguese population

    The concept of satisfaction with life is about the process of cognitive judgment that someone does in every moment of life. The main goal of this study consists on the validation of the measurement model by Satisfaction With Life Scale, translated to portuguese) for a sample of portuguese elderly (n=311), older than 60 years old (M = 68.53; DP = 6.69) that practice physical activity, using a confirmatory factor analysis. About the results, we can conclude that the measurement model of the Portuguese version of Satisfaction With Life Scale (one fator/five items) has qualities to evaluate the satisfaction with life in Portuguese elderly. It was also concluded elderly who practice more physical activity perceive higher levels of satisfaction with life.
  • Physical activity and affect of the elderly: Contribution to the validation of the Positive and Negative Affect Shedule (PANAS) in the Portuguese population
    Publication . Antunes, Raul; Couto, Nuno; Vitorino, Anabela; Monteiro, Diogo; Marinho, Daniel
    The concept of affect corresponds to the emotional dimension of subjective well-being (Diener, Emmons, Larsen, & Griffin, 1985). It is represented by two dimensions (negative affect and positive affect), which were the basis of the development of the Positive and Negative Affect Schedule - PANAS (Watson, Clark, & Tellegen, 1988). It was translated and validated for the Portuguese population by Galinha and Pais-Ribeiro (2005b). Nevertheless, because the Portuguese version was not validated in a sample of Portuguese elderly, the goals of this study consisted in the translation of the scale (PANAS) from the original version of 20 items and the validation of its measurement model (including a shortened version) for a sample of Portuguese elderly (n = 311), aged 60 years or older (M = 68.53; DP = 6.69); it was then tested by a confirmatory factorial analysis. The results demonstrated that the measurement model (two factors and 10 items) of the shortened Portuguese version of the PANAS presented acceptable psychometric qualities, which adjusted to the data in a satisfactory way (factorial weights ranging between .57 and .70 in positive affect and between .52 and .68 in negative affect). We also concluded that older adults who practice more physical activity perceive higher levels of positive affect F(2, 297) = 3,78, p < .05; η2 = .025, and lower levels of negative affect F (2, 297) = 6,24, p < .001; η2 = .040).
