Measuring older adults' abuse: evaluation of formative indicators to promote brevity

Some literature on elder abuse recommends, and practitioners claim, that there should be better assessment and screening tools. In order to improve the accuracy of measurement instruments, the purpose of this article is threefold: (a) describing the construction of an instrument with formative indicators and the survey design about the sensitive topic of elder abuse, (b) development of an analytic strategy to improve the precision of the measures by (c) evaluating the measurement instrument through quality criteria against outcomes of the instrument. We randomly selected 2,880 home-dwelling older women aged 60 and above from five European Union countries who participated in a survey on elder abuse. Prevalence data on abuse against older women was gathered using a postal (BE, FI, PT), face-to-face (BE, LT), and telephone survey (AT) but using an identical instrument. A table with outcome measures was calculated to evaluate the formative indicators of the measurement instrument, and a decision strategy for item reduction was developed. The results suggest that 12 (35%) of the original 34-indicators instrument can be omitted. The adapted version can provide the same elder abuse prevalence rates (reliability) with the same negative associations in terms of life quality (validity). The results indicate in an applied way how an elder abuse instrument can be evaluated and further developed using formative measures.

Item non-response when measuring elder abuse: influence of methodological choices

BACKGROUND Efficient actions to fight elder abuse are highly dependent on reliable dimensions of the phenomenon. Accurate measures are nevertheless difficult to achieve owing to the sensitivity of the topic. Different research endeavours indicate varying prevalence rates, which are explained by different research designs and definitions used, but little is known about measurement errors such as item non-responses and how outcomes are affected by modes of administration. METHODS A multi-national study was developed to measure domestic abuse against home-dwelling older women (aged >60 years) in Europe. The measurement instrument covered six forms of abuse, adapted from the Conflict Tactics Scale. 2880 individuals were interviewed by three different data collection methods (i.e. postal, face-to-face, telephone). RESULTS Principal component analysis of missing values of 34 indicators of abuse showed various patterns of item non-response. Moreover, principal component analysis indicated several response patterns across different types of data collection. A binary logistic regression explained that item non-response and abuse prevalence is influenced by individual characteristics (social status, vulnerability), method effects such as content (sensitivity), the order of the questions (forms of abuse), by type of data collection and the presence of assistance in survey completion. CONCLUSION The discussion revolves around how these findings could help improving measuring elder abuse. Advantages and disadvantages of the questionnaire and type of data collection methods are discussed in relation to three potential types of response errors: item positioning effect, acquiescence and social desirability.

Risk factors of severity of abuse against older women in the home setting: A multinational European study

ABSTRACT This article examines the ecological risk factors of abuse against older women. Data from 2,880 older women were randomly collected in five European countries (Austria, Belgium, Finland, Lithuania, and Portugal) using a standardized questionnaire. Results indicate that overall 30.1 % older women had at least one experience of abuse in the past year. The findings demonstrate that a single emphasis on personal risk factors (e.g., health, coping) is important but too simple: Abuse is multifaceted and is embedded in environmental (e.g., loneliness, household income) as well as macrocultural contexts (e.g., old age dependency ratio).

Prevalence of older adults' abuse and neglect in Portugal: an overview

Purpose – The purpose of this paper is to identify, describe and compare the studies of the prevalence of abuse and neglect of older adults developed in Portugal. Design/methodology/approach – A retrospective bibliographic search of seven descriptors in English and Portuguese, of academic and professional papers and university institutional repositories was performed. Findings – Of the nine studies selected, seven consisted of grey literature – research developed within the course of academic post-graduate studies. The studies were conducted on a small scale, more often than not, through a non-probabilistic convenience sampling method. From the nine studies, two instruments prevailed: the Questions to Elicit Elder Abuse aimed at older adults and the Caregiver Abuse Screen aimed at caregivers. Community-dwelling older adults self-reported a higher prevalence of abuse (between 66.7 and 86.7 per cent) than care professionals working with older adults suffering from dementia (between 26.7 and 47.4 per cent). Emotional abuse and neglect were the first and second most prevalent forms of abuse, followed by financial abuse, whereas physical abuse was the least prevalent type of abuse encountered. A poorer perception of health, not making/receiving visits and residing in an urban area were the more consistent variables associated with abuse of older adults. Originality/value – Overall, this paper provides a first consideration to the prevalence rates of older adult abuse and neglect from research studies in Portugal. The revised design studies and screening methods employed can help researchers improve future study design and move from the description to a more theoretically oriented research. Furthermore, it can help practitioners learn screening methods and discover the findings associated with abuse.

Ambient Assisted Living Technology: Comparative perspectives of users and caregivers

Developed societies are currently facing severe demographic changes: the world population is ageing at an unprecedented rate. This demographic trend will be also followed by an increase of people with physical limitations. New challenges are being raised to the traditional health care systems, not only in Portugal, but also in all other European states. There is an urgent need to find solutions that allow extending the time people can live in their preferred environment by increasing their autonomy, self-confidence and mobility. AAL4ALL is a project currently being developed in cooperation with 34 Portuguese interdisciplinary partners, from industry to academia, R&D and social disciplines, which employs a novel conceptual approach through the development of an ecosystem of products and services for Ambient Assisted Living (AAL) associated to a business model and validated through large scale trial. This paper presents a comparative perspective of the needs and attitudes towards technology of the AAL users and caregivers identified in the analysis of a set of three different surveys: a users survey targeted at the Portuguese seniors and pre-seniors; an informal caregivers survey targeted at the family, friends and neighbours who provide care without any financial compensation; and a formal caregivers survey targeted at physicians, nurses, psychologists, social workers, and direct-care workers providing care to elders. The first results indicate that AAL solutions must be affordable, user friendly and have a true perceived benefit to their users.

O luto em adultos idosos: natureza do desafio individual e das variáveis contextuais em diferentes modelos

The loss of a spouse in old age is one of the most significant, but least investigated events in the life cycle. With increasing life expectancy, widowhood in older adults occurs increasingly later in the life cycle. It is an expectable event and may be advantageously conceptualized as a major psychosocial transition that involves the reconfiguration of the meaning of life and its purpose. The present article discusses some of the main models of the grieving process and the effect of some individual and contextual variables on reactions regarding the loss of a spouse. It focuses mainly on Stroebe and Schut dual process model as well as on its theoretical and practical implications.The loss of a spouse in old age is one of the most significant, but least investigated events in the life cycle.

The Caregiver Perspective: An Assistive AAL Platform

The Ambient Assisted Living area has spawned several projects that aim to help the user on his/her daily activities. The AAL4ALL (ambient assisted living for all) project aims to develop a unified ecosystem using fully compatible devices and services. The UserAccess platform is part of the AAL4ALL and has as a goal to provide assistance to a type of actor that is commonly forgotten in the Ambient Assisted Living area, the caregiver. This paper presents the architecture, implementation, and interfaces, along with a brief analysis of caregiver’s needs and work related issues.

Book Review: We Are Unique When We Cry

Crying is an important human behavior, and we are all aware of the impact that our tears can have on others, and theirs on us. From an ethological perspective, the survival value of crying is clear, particularly in the case of infants and small children. However, much less is known about the evolutionary meaning of crying, in particular its relationship with other abilities developed over millions of years such as Theory of Mind, empathy, consciousness, morality, altruism, and love. These relationships are explored in a new book by Michael Trimble: Why humans like to cry: Tragedy, evolution and the brain.
