The development of social values in childhood and early adolescence
Corruption erodes people's beliefs in morality and justice
In this research, we argue that corruption adversely affects individuals' perceived morality of politicians and their sense of justice, eroding some key values by which societies are guided. We further analyzed how the erosion of these key values might be negatively associated with people's well‐being. We found support for our contentions through multiple studies, including a cross‐national study comprising 82 countries surveyed over 32 years (St…
Leaders or Villains? The Role of Corruption in Shaping the Stereotypes of Politicians
The ways in which politicians are stereotyped contribute to perceptions of the legitimacy of their power, status and leadership. In this research, we examined how corruption impacts the stereotypes of politicians. By examining stereotype content, we posited that corruption should elicit morality‐related traits, while in contexts of no corruption, both morality and competence should emerge as key dimensions. With two experiments ( N combined = 272…

Too old for technology? Stereotype threat and technology use by older adults
Older adults are often stereotyped as having less technological ability than younger age groups. As a result, older individuals may avoid using technology due to stereotype threat, the fear of confirming negative stereotypes about their social group. The present research examined the role of stereotype threat within the Technology Acceptance Model (TAM). Across two studies, experiencing stereotype threat in the technological domain was indirectly…
Cognitive functioning mediates the relationship between self-perceptions of aging and computer use behavior in late adulthood
Although information and communication technologies have become an integral part of contemporary societies, substantial proportions of the older population remain distant from these digital tools. This stresses the importance of identifying age-specific factors that facilitate or prevent technology adoption among older age groups. Despite being powerful determinants of behavior and health in late adulthood, little is known about the role of stere…

Behavioural change box? Applying the COM-B model to understand behavioural triggers that support consumption of fruits and vegetable among subscribers of a fruit and vegetable box scheme
Objective: To understand the key mechanisms that support healthy dietary habits promoted by fruit and vegetable (F&V) box schemes, testing relevant behaviour change triggers identified under the COM-B model in an evaluation research study of a Portuguese F&V box scheme (PROVE). Design: Correlation study with a post-test-only non-equivalent group design based on survey data. The mechanisms underpinning the differences between subscribers and non-s…

Determinants of Ageism against Older Adults
Ageism is a widespread phenomenon and constitutes a significant threat to older people’s well-being. Identifying the factors contributing to ageism is critical to inform policies that minimise its societal impact. In this systematic review, we gathered and summarised empirical studies exploring the key determinants of ageism against older people for a period of over forty years (1970–2017). A comprehensive search using fourteen databases identifi…
How to Achieve a Healthier and More Sustainable Europe by 2040 According to the Public? Results of a Five-Country Questionnaire Survey
The aim of this paper is to understand public preferences for several future scenarios of achieving a healthier, more equitable and sustainable Europe, which differ in the way the society is organized (individualistically vs. collectively) and in the driving sector (public vs. private). To achieve this aim, we conducted a questionnaire survey using representative samples for five European countries in 2018. About three thousand respondents chose …
A casa dos avós
Existem evidências de que crianças a partir dos seis anos de idade já partilham a conceção paternalista das pessoas mais velhas como "simpáticas, mas incompetentes". De forma inovadora, o presente trabalho visa estudar este tema no contexto português procurando explorar o papel da frequência e qualidade do contacto com os avós como uma via para a diminuição destas representações negativas. Para tal, 145 crianças do ensino básico (M = 12.14; SD = …
Ten Lessons for Good Practice for the Inherit Triple Win
The world's challenges of climate change, damage to ecosystems, and social and health inequalities require changes in human behaviours at every level of organisation, among governments, business, communities, and individuals. An important question is how behaviour change can be enabled and supported at the scale and speed required. The research reported in this paper describes important lessons for good practice in changing contexts to modify beh…
Equity, Health, and Sustainability with PROVE
PROVE is a Portuguese program that empowers small-scale farmers organized into local networks to directly commercialize baskets of locally produced fruits and vegetables to consumers. This study applied a post-test-only non-equivalent group design to evaluate the resulting influence on the social empowerment of farmers and on consumer diets. The method included conducting a survey of PROVE farmers ( n = 36) and a survey of PROVE consumers ( n = 2…

The SeniorTec program was carried out in the framework of the European project Cordon Gris, its objective was to promote intergenerational relationships. The activity was hosted by the old persons who participate in the European project Cordon Gris and was attended by university students from Higher School of Health of Alcoitão and ISCTE-University Institute of Lisbon. Learning sessions were delivered in this action: a Nutrition Workshop and a Fi…
The Inherit Model
The need for analysis and action across the interrelated domains of human behaviors and lifestyles, environmental sustainability, health and inequality is increasingly apparent. Currently, these areas are often not considered in conjunction when developing policies or interventions, introducing the potential for suboptimal or conflicting outcomes. The INHERIT model has been developed within the EU-funded project INHERIT as a tool to guide thinkin…
Perceived age discrimination across age in Europe
Ageism is recognized as a significant obstacle to older people's well-being, but age discrimination against younger people has attracted less attention. We investigate levels of perceived age discrimination across early to late adulthood, using data from the European Social Survey (ESS), collected in 29 countries (N = 56,272). We test for approximate measurement invariance across countries. We use local structural equation modeling as well as mod…
Images of old age in YouTube
This article presents an analysis of the most viewed YouTube videos under the labels ‘old age’, ‘older age’ and ‘senior citizens’. As powerful sources that transmit cultural information which either perpetuates or undermines cultural stereotypes at a worldwide level, channels of information such as YouTube offer a valuable glimpse at those images of ageing and old age which are shared and consumed by nowadays viewers. This study offers an analysi…
Lisbon Street Campaign Against Ageism
Portugal currently has the fifth highest percentage of older people among countries: 27% of the population is aged 60 years or older and this proportion is expected to reach 41% by 2050 (United Nat
Perceived Age Discrimination as a Mediator of the Association Between Income Inequality and Older People’s Self-Rated Health in the European Region
Concrete instances of age discrimination in unequal societies are an important psychosocial stressor for older people. Awareness that the perception of ageism can be an important stressor and affect older patient's self-reported health has important implications for the way health practitioners understand and treat the sources of patient's health problems in later life
Subjective Social Status of Older People Across Countries
The proportion of older people who are employed is an important factor that is related to perceptions of the social status of older people in less modern societies. The individual and societal implications are discussed, specifically in relation to policies promoting active aging
Revisiting the Paradox of Well-being
The findings clarify the relationship between age and SWB by demonstrating that the paradox of well-being is conditional on the economic context. Implications for individual- and country-level strategies for successful aging are discussed
GerAções Lx
In Portugal, there has been increased interest in intergenerational activities with the potential to help promote a more inclusive society, especially in view of the expected aging of the populatio
Estou mais seguro na minha cidade do que os outros
Esta pesquisa pretendeu estudar o optimismo comparativo face aos riscos urbanos e explorar o papel que a identificação com a cidade de residência tem neste processo. O estudo foi realizado através de um inquérito a 156 estudantes universitários, residentes em Lisboa, Huelva e Lyon. Os resultados revelaram a existência de optimismo comparativo face a todos os riscos urbanos considerados (carteirismo, assalto da casa, terrorismo e queda de avião): …
Threat or Boost? Social Comparison Affects Older People's Performance Differently Depending on Task Domain
The research demonstrates that a threatening comparison can result in underperformance by older people both in negatively and positively self-stereotyped task domains. It also demonstrates that social comparison with younger people can enhance older people's performance in a positively stereotyped task domain. The implications for creating circumstances likely to enable older people to achieve their full potential are discussed

Towards successful social impact assessment follow-up
Since 1997, an extensive monitoring programme has been assessing the psychosocial impacts of the solid waste incinerator of the Oporto region of Portugal. This paper describes the theoretical psychosocial model that guided this process; this stresses the joint effect of mediating variables (environmental annoyance and risk perception) and moderating variables (attitudes towards the incinerator and local identity). The test of the model and some m…
