Preliminary evaluation of a tailored difficulty index for long-distance family caregivers of older adults with dementia.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe bulk of research focused on family caregiving for persons with Alzheimer's Disease and Related Dementias (ADRD) has been limited to those in close proximity to their care-recipient. The unique needs of the growing number of long-distance caregivers (LDCs) remain understudied and unaddressed. Existing measures of caregiver strain, which were primarily developed for and with geographically proximate caregivers, do not adequately capture the unique challenges faced by LDCs (e.g., difficulties with ensuring and monitoring care from afar). Thus, the current study aims to evaluate the suitability and psychometric properties of a caregiving difficulty index tailored for LDCs.
methodsData were from 40 participants enrolled in a pilot feasibility trial of a psycho-educational intervention for burdened LDCs of older adults with ADRD. Participants completed several measures assessing sociodemographic characteristics, caregiver burden, strain (i.e., family and work conflict, role captivity), and the 9-item difficulty index. An exploratory factor analysis (EFA) was conducted to examine the index's underlying factor structure. Pearson's correlations were used to assess the relationship among the final items and other validated measures of burden and strain. Cronbach's alphas were calculated for the total index and each subscale to evaluate internal consistency.
resultsEFA findings revealed that retention of eight out of the original nine items yielded the best model fit, with items loading onto two distinct components capturing general caregiving and distance-specific challenges. Cronbach's alphas were 0.79 for the total measure and between 0.67-0.80 for its subscales. Overall difficulty scores were also significantly positively related to caregiver burden (r = 0.42) and strain (rs = 0.31-0.44). Results provide initial evidence supporting the index's reliability and validity.
conclusionFindings provide preliminary support for the potential suitability of the 8-item index for use with LDCs and underscore the importance of tailored assessments to adequately measure the unique challenges associated with the long-distance caregiving experience.
