Multidimensional structure of the Groningen Frailty Indicator in community-dwelling older people.

ABSTRACT:

Background

Due to the rapidly increasing number of older people worldwide, the prevalence of frailty among older adults is expected to escalate in coming decades. It is crucial to recognize early onset symptoms to initiate specific preventive care. Therefore, early detection of frailty with appropriate screening instruments is needed. The aim of this study was to evaluate the underlying dimensionality of the Groningen Frailty Indicator (GFI), a widely used self-report screening instrument for identifying frail older adults. In addition, criterion validity of GFI subscales was examined and composition of GFI scores was evaluated.

Methods

A cross-sectional study design was used to evaluate the structural validity, internal consistency and criterion validity of the GFI questionnaire in older adults aged 65 years and older. All subjects completed the GFI questionnaire (n = 1508). To assess criterion validity, a smaller sample of 119 older adults completed additional questionnaires: De Jong Gierveld Loneliness Scale, Hospital Anxiety Depression Scale, RAND-36 physical functioning, and perceived general health item of the EuroQol-5D. Exploratory factor analysis and Mokken scale analysis were used to evaluate the structural validity of the GFI. A Venn diagram was constructed to show the composition of GFI subscale scores for frail subjects.

Results

The factor structure of the GFI supported a three-dimensional structure of the scale. The subscales Daily Activities and Psychosocial Functioning showed good internal consistency, scalability, and criterion validity (Daily Activities: Cronbach's ? = 0.81, H(s) = .84, r = -.62; Psychosocial Functioning: Cronbach's ? = 0.80, H(s) = .35, r = -.48). The subscale Health Problems showed less strong internal consistency but acceptable scalability and criterion validity (Cronbach's ? = .57, H(s) = .35, r = -.48). The present data suggest that 90% of the frail older adults experience problems in the Psychosocial Functioning domain.

Conclusions

The present findings support a three-dimensional factor structure of the GFI, suggesting that a multidimensional assessment of frailty with the GFI is possible. These GFI subscale scores produce a richer assessment of frailty than with a single overall sum GFI score, and likely their use will contribute to more directed and customized care for older adults.

Project description:Frail and pre-frail older people often need to take medications. However, factors related to medication adherence among this population remain unclear, warranting further research. This study aims to identify correlates of medication adherence among frail and pre-frail older adults. From November 2020 to December 2020; a total of 4218 community-dwelling residents aged ≥ 60 years were interviewed by a cross-sectional survey in China. Data on subjects' general information; medication adherence; and frailty status was obtained via the face-to-face structured questionnaire. Logistic regression models were fitted; separately; to examine these factors linked to medication adherence. We found that 36.2% (n = 1527) and 18.8% (n = 792) of respondents were classified as pre-frail and frail. According to the Morisky scale scores, 66.74% (n = 2815) were found to have adequate medication adherence, and 33.26% (n = 1403) were found to have inadequate medication adherence. Among the pre-frail respondents, age (adjusted odds ratio (AOR) = 1.64; 95% confidence interval (CI): 1.18-2.29, P = 0.003), marital status (AOR = 1.52; 95% CI: 1.04-2.21, P = 0.030), smoking status (AOR = 0.61; 95% CI: 0.37-0.99, P = 0.044), and functional ability (AOR = 0.72; 95% CI: 0.58-0.91, P = 0.006) were significantly related to medication adherence. Among them, advanced age and single were risk factors, which were positively related to the medication adherence of subjects in pre-frailty, while quitting smoking and limited functional ability contributed to improving their medication adherence. In contrast, only age (AOR = 1.77; 95% CI: 1.16-2.69, P = 0.008) was significantly associated with medication adherence among frail subjects. Influencing factors to medication adherence of old people in pre-frailty and frailty have been enriched, which provides a certain reference for promoting medication adherence in this population. Future adherence intervention methods should be designed based on these factors.

Project description:INTRODUCTION:An increasing number of investigations highlight the complex nature of frailty; therefore, the use of multidimensional assessment instruments could be useful in clinical decision-making. Frail people are found mainly in the community setting which is why this is the ideal environment for early screening and intervention. For this purpose, it is necessary to have valid, time-effective and easy-to-use frailty assessment instruments. The aim of this review is to critically appraise, compare and summarise the quality of the measurement properties of all multidimensional instruments with an integral approach to identify frailty in community-dwelling people. METHODS AND ANALYSIS:Medline, Psychological Information Database (PsycINFO) and Cumulative Index to Nursing and Allied Health Literature (CINAHL) will be searched from their inception dates. We will also conduct searches in databases of grey literature. No limits will be applied for language. A highly sensitive validated search filter will be used for finding studies on measurement properties. An additional search including the names of the instruments found in the initial search will also be undertaken. Studies aiming at the development of a measurement instrument, the evaluation of one or more measurement properties or the evaluation of its interpretability will be included. The instrument should have an integral approach (physical, psychological and social) and it should measure all three domains. The context of use should be a community setting. Two reviewers independently will screen the references and assess the risk of bias by consensus-based standards for the selection of health measurement instruments checklist. To assess the overall evidence for the measurement properties of the identified instruments, the results of the different studies, adjusted for their methodological quality, will be combined. ETHICS AND DISSEMINATION:Ethical approval and patient consent are not required as this is a psychometric review based on published studies. The results of this review will be disseminated at conferences and published in an international peer-reviewed journal. PROSPERO REGISTRATION NUMBER:CRD42019120212.

Project description:So far, it has not yet been studied whether socioeconomic status is associated with distinct frailty components and for which frailty component this association is the strongest. We aimed to examine the association between socioeconomic status and frailty and frailty components. In addition we assessed the mediating effect of the number of morbidities on the association between socioeconomic status and other frailty components.This is a cross-sectional study of pooled data of The Older Persons and Informal Caregivers Survey Minimum DataSet in the Netherlands among community-dwelling persons aged 55 years and older (n = 26,014). Frailty was measured with a validated Frailty Index that consisted of 45 items. The Frailty Index contained six components: morbidities, limitations in activities of daily living (ADL), limitations in instrumental ADL (IADL), health-related quality of life, psychosocial health and self-rated health. Socioeconomic indicators used were education level and neighbourhood socioeconomic status.Persons with primary or secondary education had higher overall frailty and frailty component scores compared to persons with tertiary education (P < .001). Lower education levels were most consistently associated with higher overall frailty, more morbidities and worse self-rated health (P < .05 in all age groups). The strongest association was found between primary education and low psychosocial health for persons aged 55-69 years and more IADL limitations for persons aged 80+ years. Associations between neighborhood socioeconomic status and frailty (components) also showed inequalities, although less strong. The number of morbidities moderately to strongly mediated the association between socioeconomic indicators and other frailty components.There are socioeconomic inequalities in frailty and frailty components. Inequalities in frailty, number of morbidities and self-rated health are most consistent across age groups. The number of morbidities a person has play an important role in explaining socioeconomic inequalities in frailty and should be taken into account in the management of frailty.
