Psychometrics

Background: Dementia is prevalent among older adults and frequently causes dependence on family caregivers. Caregivers may experience a form of stigmatization called affiliate stigma that negatively affects their mental health. The current study sought to establish the psychometric properties of a tool to measure affiliate stigma among Iranian caregivers. Methods: Overall, 541 caregivers of older people with dementia were included in this cross sectional study.

Objective To develop new patient-reported outcome (PRO) measures to better understand feelings of loss in caregivers of individuals with traumatic brain injury (TBI). Design Cross-sectional survey study. Setting Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility. Participants Caregivers (N=560) of civilians with TBI (n=344) or service members/veterans (SMVs) with TBI (n=216). Interventions Not applicable.

Objective To examine the reliability and validity of Patient-Reported Outcomes Measurement Information System (PROMIS) measures of sleep disturbance and fatigue in traumatic brain injury (TBI) caregivers and to determine the severity of fatigue and sleep disturbance in these caregivers. Design Cross-sectional survey data collected through an online data capture platform. Setting A total of 4 rehabilitation hospitals and Walter Reed National Military Medical Center.

Background Higher patient-caregiver mutuality is associated with improved patient and caregiver outcomes, but no studies have tested the psychometric characteristics of the mutuality scale (MS) in heart failure (HF) patient and caregiver population. Objectives To test the validity and reliability of the MS. Methods A cross-sectional design. The MS validity and reliability were tested with confirmatory factor analysis (CFA) and hypothesis testing, and with Cronbach's alpha and model-based internal consistency index, respectively.

Background Clinicians, researchers and politicians are seeking to better assess caregiver's needs. Challenges exist in broadly implementing this so as to provide appropriate support. The aim of this review was to compile self-administered instruments for assessment of caregiver's needs that are deemed to be scientifically robust. Methods The Medline database was searched for publications reporting self-administered instruments assessing caregiver's needs with acceptable psychometric properties.

Context Previous studies have supported the psychometric properties of the 22-Item Zarit Burden Interview (ZBI-22) scale among family caregivers of people with various disorders, including Parkinson's disease (PD). However, its short forms have not been psychometrically tested among PD family caregivers, and available psychometric analyses have not accounted for the ordinal nature of item-level data.

Objective: To translate, culturally adapt, and psychometrically evaluate the Spanish version of the "Scale for End-of Life Caregiving Appraisal" (SEOLCAS).; Method: Observational cross-sectional study. Convenience sample of 201 informal end-of-life caregivers recruited in a southern Spanish hospital. The reliability of the questionnaire was assessed through its internal consistency (Cronbach's α) and temporal stability (Pearson's correlation coefficient [r] between test-retest). The content validity index of the items and the scale was calculated.

Background: In the UK, there are currently 800 000 people living with dementia. This number is expected to double in the next 20 years. Two-thirds of people with dementia live in the community supported by informal carers. Caring for a person with dementia has adverse effects on psychological, physical, social wellbeing and quality of life. The measurement of quality of life of carers of people with dementia is increasingly of interest to health and social care practitioners and commissioners, policymakers, and carers themselves.

Background: Informal care is essential for many people with dementia (PwD), but it often results in a considerable burden for the caregiver. The perseverance time instrument integrates the aspect of perceived burden with the caregiver's capacity to cope with the burden, in contrast to most available instruments, which measure solely the burden of caregiving.

Well-prepared informal caregivers play an important role in heart failure (HF) care, so an instrument to evaluate their preparedness to care is important. To date, HF caregiver preparedness has been rarely investigated quantitatively. The Caregiver Preparedness Scale (CPS) has been used in other chronic condition populations, but its psychometric characteristics have never been tested in HF caregivers. The purpose of this study was to test the validity and reliability of the 8-item CPS in HF caregivers.
