The Development of Two New Computer Adaptive Tests To Evaluate Feelings of Loss in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Feelings of Loss-Self and Feelings of Loss-Person With Traumatic Brain Injury

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.

Understanding Health-Related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Fatigue and Sleep Disturbance Item Banks

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.

Psychometric characteristics of the mutuality scale in heart failure patients and caregivers

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.

Assessment of informal caregiver's needs by self-administered instruments: A literature review

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.

Assessment of Burden Among Family Caregivers of People With Parkinson's Disease Using the Zarit Burden Interview

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.

Psychometric evaluation and cultural adaptation of the Spanish version of the "Scale for End-of Life Caregiving Appraisal"

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.

How best to assess quality of life in informal carers of people with dementia; A systematic review of existing outcome measures

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.

Perseverance time of informal caregivers for people with dementia: construct validity, responsiveness and predictive validity

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.

Psychometric evaluation of the Caregiver Preparedness Scale in caregivers of adults with heart failure

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.

Measuring burden in dementia caregivers: Confirmatory factor analysis for short forms of the Zarit Burden Interview

Introduction: To examine the psychometric properties of different short versions of the Zarit Burden Interview (ZBI), and to find an efficient and valid short version for clinical use among dementia caregivers.; Materials and Methods: A total of 270 Taiwanese dementia caregivers filled out the full form of the ZBI, which contains 22 items. Using the 22-item ZBI, we used confirmatory factor analysis (CFA) to calculate the fit indices of all proposed short versions with various items to determine useful short versions.
