The use of codesign methods is becoming increasingly common practice to involve and engage research participants in health research. Through codesign, end-users and stakeholders can contribute their own perspectives and experiences to solve a common problem. This article describes how a 5-day codesign sprint can be used to find solutions to…

Prospective memory helps us to remember to perform tasks in the future. Prospective memory can be either time or event based. The goal of this study was to determine time- and event-based prospective memory in autistic adults across the life span. Autistic (n = 82) and non-autistic (n = 111) adults, aged between 30 and 86 years, performed the…

Normative studies are needed to obtain norms for comparing individuals with the reference population on relevant clinical or educational measures. Norms can be obtained in an efficient way by regressing the test score on relevant predictors, such as age and sex. When several measures are normed with the same sample, a multivariate regression-based…

Education is one sector being challenged by aging staff, as well as by increased pressure to innovate. In order to cope with these challenges, educational institutions require teaching staff members, who include teachers, support staff and managers, to show a high level of employability. In this survey-based study, the predictive value of…

Background: Information regarding the common-daily support needs of older people with intellectual disabilities remains scarce, despite the necessity of such knowledge to the provision of adequate support. This exploratory study aims to identify the most important support needs. Method: A mixed-method design was conducted, in which 11…

Autism spectrum conditions were once seen as a predominantly male condition. This has caused a paucity of information on common events in the lives of women, such as menstruation and menopause. Some smaller studies indicate that autistic women might suffer from increased difficulties surrounding these events. This study aims to investigate whether…

Participatory research actively engages participants in some or all stages of the research process -- from deciding on scope and problem statement to actively collecting data to disseminating results and effecting change. Considering the shifting roles of participants and researchers in participatory ageing research, to the academic, participatory…

The aim of the study is to illustrate a comprehensive approach to item bias in cross-cultural research by integrating quantitative and qualitative data in a mixed methods design. We studied responses and response processes of Dutch and Spanish participants to quality of life items from five international studies. Item bias was evaluated by…

Background: The ageing of people with intellectual disabilities, involving consequences like dementia, creates a need for methods to support care staff. One promising method is Dementia Care Mapping (DCM). This study examined the effect of DCM on job satisfaction and care skills of ID-care staff. Methods: We performed a quasi-experimental study in…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

Studies on aging and migration often note a 'language barrier' for older migrants when communicating in a (medical) second language (L2) context. Yet how a limited L2 proficiency impacts the aging process of migrant adults has, so far, not been systematically investigated. This question is important given that having a limited L2 proficiency may…

This article focuses on research ethics in highly intimate research with possible impact on life and death. In order to stimulate an open-ended dialogue about research ethics, we reflect on four ethical challenges that came up during our research into older people with a wish to die. Drawing on our experiences, we discuss (1) the possibly…

Whereas executive functions are known to be closely tied to successful language processing in children and younger adults, less is known about how age-related decline in these functions affects language processing in elderly adults. Because the abilities to use linguistic context and resolve potential ambiguities such as between an idiom's…

The purpose of this paper was to analyse the core of the quality of life, intended as a complex construct with specific and transversal features. The approach to this issue, by linking it to the great emergency of disability in adulthood, pushes the analysis into deep conceptual pedagogical reflections, which lead the authors' initial reflections…

Background: Adults with Down syndrome (DS) are at risk for age-related painful physical conditions, but also for under-reporting pain. Pictograms may facilitate self-report of pain, because they seem suitable for the global visual processing in DS and for iconic representation of abstract concepts. Method: Participants (N = 39, M age = 41.2)…
