OBJECTIVES To assess the reliability, construct validity, and predictive (concurrent) validity of the Tilburg Frailty Indicator (TFI), a self-report questionnaire for measuring frailty in older persons. DESIGN Cross-sectional. SETTING Community-based. PARTICIPANTS Two representative samples of community-dwelling persons aged 75 years and older (n =(More)
In order to be able to identify frail community-dwelling older people, a reliable and valid definition of the concept of frailty is necessary. The aim of this study was to provide an overview of the literature on conceptual and operational definitions of frailty, and to determine which definitions are most appropriate for identifying frail(More)
PURPOSE To assess the predictive validity of frailty and its domains (physical, psychological, and social), as measured by the Tilburg Frailty Indicator (TFI), for the adverse outcomes disability, health care utilization, and quality of life. DESIGN AND METHODS The predictive validity of the TFI was tested in a representative sample of 484(More)

To gain more insight into nutritional care policies in Dutch health care organizations, this study investigated screening, treatment, and other quality indicators of nutritional care. METHODS In 2007 a cross-sectional(More)

SETTING Community-based. PARTICIPANTS A representative sample of 484 community-dwelling persons aged 75 years and older. MEASUREMENTS The Tilburg Frailty(More)

OBJECTIVES Most conceptual and operational definitions of frailty place heavy emphasis on the physical problems encountered by older people. The accompanying models are based largely on a medical model. An integral approach is almost never adopted. This study aims to develop both an integral operational definition of frailty and an integral conceptual model(More)
INTRODUCTION There are many different conceptual definitions of frailty in circulation. Most of these definitions focus mainly on physical problems affecting older people. Only a few also draw attention to other domains of human functioning such as the psychological domain. The authors of this article fear that this could lead to fragmentation of care for(More)
AIM This paper is a report of a study conducted to test three hypotheses derived from an integral conceptual model of frailty. BACKGROUND   The integral model of frailty describes the pathway from life-course determinants to frailty to adverse outcomes. The model assumes that life-course determinants and the three domains of frailty (physical,(More)
BACKGROUND & AIMS Consensus regarding definitions of malnutrition and methods to assess nutritional state is lacking. We propose a definition and its operationalization. METHODS A definition was formulated on the basis of the pathophysiology of malnutrition, while reviewing the metabolic and physiological characteristics of different populations,(More)
