Development of the Valued Living Questionnaire – Comprehension Support version (VLQ-CS) and validation in adults with acquired brain injury

Abstract

Purpose Valued living (acting in accordance with personal values) is associated with better outcomes after acquired brain injury (ABI), but its measurement using the Valued Living Questionnaire (VLQ) may not be valid due to comprehension errors relating to structure and content. We aimed to modify the VLQ to improve its accessibility and evaluate construct validity and reliability in an ABI cohort. Materials and methods Adaptations made in the VLQ – Comprehension Support version (VLQ-CS) used established communication support methods and addressed common comprehension errors. 103 community-dwelling participants (34% female; mean age 52.17, range 19–79) with ABI (66% stroke, 16% TBI, 18% other) completed the VLQ-CS, and measures of convergent (valued living, mood, wellbeing, psychological inflexibility) and divergent validity (subjective memory). Test-retest reliability was evaluated with repeated administrations 6–8 weeks apart for a subset of participants (n = 44), using Intraclass Correlation Coefficients (ICCs). Results Convergent validity was supported; VLQ-CS scores were positively correlated with measures of valued living (r=.60–.65) and wellbeing (r=.64–.67), and negatively correlated with depression (r=-0.56–.58), anxiety (r=-0.35–.38) and psychological inflexibility (r=-0.37–.41). Divergent validity was marginal (r=-0.29). Test-retest reliability was good for the VLQ-CS Composite score (ICC=.80). Conclusions The VLQ-CS shows promise as a valid, reliable measure of valued living post-ABI. Future research should extend to neurotypical and other clinical populations.
