The reliability and validity of the TBI-CareQOL system in four diverse caregiver groups.

ABSTRACT:

Purpose

Establishing the psychometric reliability and validity of new measures is an ongoing process. More work is needed in to confirm the clinical utility of the TBI-CareQOL measurement development system in both an independent cohort of caregivers of traumatic brain injury (TBI), as well as in additional caregiver groups.

Methods

An independent cohort of caregivers of people with TBI (n = 139), as well as three new diverse caregiver cohorts (n = 19 caregivers of persons with spinal cord injury, n = 21 caregivers for persons with Huntington disease, and n = 30 caregivers for persons with cancer), completed 11 TBI-CareQOL measures (caregiver strain; caregiver-specific anxiety; anxiety; depression; anger; self-efficacy; positive affect and well-being; perceived stress; satisfaction with social roles and activities; fatigue; sleep-related impairment), as well as two additional measures to examine convergent and discriminant validity (PROMIS Global Health; the Caregiver Appraisal Scale).

Results

Findings support the internal consistency reliability (all alphas > 0.70 with the vast majority being > 0.80 across the different cohorts) of the TBI-CareQOL measures. All measures were free of ceiling effects, and the vast majority were also free of floor effects. Convergent validity was supported by moderate to high correlations between the TBI-CareQOL and related measures, while discriminant validity was supported by low correlations between the TBI-CareQOL measures and unrelated constructs.

Conclusion

Findings indicate that the TBI-CareQOL measures have clinical utility in caregivers of people with TBI, as well as in other caregiver groups. As such, these measures should be considered as important outcome measures for clinical trials aiming to improve caregiver outcomes.

Project description:BackgroundIn responding to the potential challenges in the transition from childhood to adulthood for individuals with autism spectrum disorders (ASD) in China, a novel conception of "ALSO" was proposed to bridge the transitional needs and early intervention. To facilitate the application of ALSO in early intervention, ALSOLIFE skills assessment system (ALSOLIFE Assessment) was developed to enable caregivers to evaluate their children's skills guided by the ALSO conception. Given that the critical shortage of qualified professionals in China, many caregivers of children with ASD must function as home therapists. To address the practical needs of Chinese families of children with ASD, ALSOLIFE Assessment is designed as a free, online, technology-assisted, self-operated and behavioral intervention approaches supported system. The assessment report then further served as the basis for caregivers to deliver the tailored educational intervention to their children. Although ALSOLIFE Assessment provides caregivers a home-based intervention program, it is still unclear whether its evaluation is reliable and accurate. Therefore, we conduct this study to investigate the reliability and validity of the ALSOLIFE Assessment.MethodsA total of 1,050 children with ASD (1 to 10 years old) were recruited from 31 provinces of mainland China. Their caregivers participated simultaneously as ALSOLIFE Assessment evaluators. The testing results of Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) and Psychoeducational Profile-3 (PEP-3) were also collected for a portion of the child participants (VB-MAPP, N=34; PEP-3, N=31) to check criterion-related validity.ResultsThe reliability and validity of the ALSOLIFE Assessment satisfied psychometric requirements after the reduction from 511 to 464 items. Exploratory factor analysis (EFA) of ALSOLIFE Assessment scoring data yielded six factors, and confirmatory factor analysis (CFA) verified the best fitting construct model is a bifactorial model with one general factor and six group factors. Compared to the VB-MAPP and PEP-3, the ALSOLIFE Assessment exhibited good criterion-related validity across three levels: total scores, 6 skill domains, and 22 skill subdomains. The reliability tests indicated its strong internal consistency, test-retest reliability, and inter-rater reliability.ConclusionsThe reliability and validity of the revised ALSOLIFE Assessment (464-items) satisfied psychometric requirements. It is essential to develop validated and comprehensive evaluation tools, embedded on the needs of Chinese families of children with ASD.

Project description:BackgroundIn-shoe pressure measurement systems are used in research and clinical practice to quantify areas and levels of pressure underfoot whilst shod. Their validity and reliability across different pressures, durations of load and contact areas determine their appropriateness to address different research questions or clinical assessments. XSENSOR is a relatively new pressure measurement device and warrants assessment.Research questionDoes the XSENSOR in-shoe pressure measurement device have sufficient validity and reliability for clinical assessments in diabetes?MethodsTwo XSENSOR insoles were examined across two days with two lab-based protocols to assess regional and whole insole loading. The whole insole protocol applied 50-600 kPa of pressure across the insole surface for 30 seconds and measured at 0, 2, 10 and 30 seconds. The regional protocol used two (3.14 and 15.9 cm2 surface area) cylinders to apply pressures of 50, 110 and 200 kPa to each insole. Three trials of all conditions were averaged. The validity (% difference and Root Mean Square Error: RMSE) and repeatability (Bland Altman, Intra-Class Correlation Coefficient: ICC) of the target pressures (whole insole) and contact area (regional) were outcome variables.ResultsRegional results demonstrated mean contact area errors of less than 1 cm2 for both insoles and high repeatability (≥0.939). Whole insole measurement error was higher at higher pressures but resulted in average peak and mean pressures error < 10%. Reliability error was 3-10% for peak pressure, within the 15% defined as an analytical goal.SignificanceErrors associated with the quantification of pressure are low enough that they are unlikely to influence the assessments of interventions or screening of the at-risk-foot considering clinically relevant thresholds. Contact area is accurate due to a high spatial resolution and the repeatability of the XSENSOR system likely makes it appropriate for clinical applications that require multiple assessments.

Project description:Background Universal Health coverage (UHC) is the mantra of the twenty-first century yet knowing when it has been achieved or how to best influence its progression remains elusive. An innovative framework for High Performing Healthcare (HPHC) attempts to address these issues. It focuses on measuring four constructs of Accountable, Affordable, Accessible, and Reliable (AAAR) healthcare that contribute to better health outcomes and impact. The HPHC tool collects information on the perceived functionality of health system processes and provides real-time data analysis on the AAAR constructs, and on processes for health system resilience, responsiveness, and quality, that include roles of community, private sector, as well as both demand, and supply factors affecting health system performance. The tool attempts to capture the multidimensionality of UHC measurement and evidence that links health system strengthening activities to outcomes. This paper provides evidence on the reliability and validity of the tool. Methods Internet survey with non-probability sampling was used for testing reliability and validity of the HPHC tool. The volunteers were recruited using international networks and listservs. Two hundred and thirteen people from public, private, civil society and international organizations volunteered from 35 low-and-middle-income countries. Analyses involved testing reliability and validity and validation from other international sources of information as well as applicability in different setting and contexts. Results The HPHC tool’s AAAR constructs, and their sub-domains showed high internal consistency (Cronbach alpha >.80) and construct validity. The tool scores normal distribution displayed variations among respondents. In addition, the tool demonstrated its precision and relevance in different contexts/countries. The triangulation of HPHC findings with other international data sources further confirmed the tool’s validity. Conclusions Besides being reliable and valid, the HPHC tool adds value to the state of health system measurement by focusing on linkages between AAAR processes and health outcomes. It ensures that health system stakeholders take responsibility and are accountable for better system performance, and the community is empowered to participate in decision-making process. The HPHC tool collects and analyzes data in real time with minimum costs, supports monitoring, and promotes adaptive management, policy, and program development for better health outcomes.

Project description:BackgroundThe four square step test (FSST) was first validated in healthy older adults to provide a measure of dynamic standing balance and mobility. The FSST has since been used in a variety of patient populations. The purpose of this systematic review is to determine the validity and reliability of the FSST in these different adult patient populations.MethodsThe literature search was conducted to highlight all the studies that measured validity and reliability of the FSST. Six electronic databases were searched including AMED, CINAHL, MEDLINE, PEDro, Web of Science and Google Scholar. Grey literature was also searched for any documents relevant to the review. Two independent reviewers carried out study selection and quality assessment. The methodological quality was assessed using the QUADAS-2 tool, which is a validated tool for the quality assessment of diagnostic accuracy studies, and the COSMIN four-point checklist, which contains standards for evaluating reliability studies on the measurement properties of health instruments.ResultsFifteen studies were reviewed studying community-dwelling older adults, Parkinson's disease, Huntington's disease, multiple sclerosis, vestibular disorders, post stroke, post unilateral transtibial amputation, knee pain and hip osteoarthritis. Three of the studies were of moderate methodological quality scoring low in risk of bias and applicability for all domains in the QUADAS-2 tool. Three studies scored "fair" on the COSMIN four-point checklist for the reliability components. The concurrent validity of the FSST was measured in nine of the studies with moderate to strong correlations being found. Excellent Intraclass Correlation Coefficients were found between physiotherapists carrying out the tests (ICC = .99) with good to excellent test-retest reliability shown in nine of the studies (ICC = .73-.98).ConclusionsThe FSST may be an effective and valid tool for measuring dynamic balance and a participants' falls risk. It has been shown to have strong correlations with other measures of balance and mobility with good reliability shown in a number of populations. However, the quality of the papers reviewed was variable with key factors, such as sample size and test set up, needing to be addressed before the tool can be confidently used in these specified populations.
