Validation of the Valued Living Questionnaire-Comprehension Support Version (VLQ-CS) in a Neurotypical Adult Cohort

The Valued Living Questionnaire-Comprehension Support version (VLQ-CS) was previously adapted from the original VLQ to measure value-consistent actions in individuals with cognitive and communication difficulties following acquired brain injury (ABI). In this study, we aimed to determine if the VLQ-CS is also a valid and reliable measure of valued living in neurotypical adults, and to compare the psychometric properties of the original and adapted VLQ across ABI and neurotypical cohorts. The VLQ-CS was completed by adults without neurological or neurodevelopmental diagnoses with an assessor via Zoom, with an average completion time of 2 minutes. To measure test-retest reliability, participants completed the VLQ-CS again after 2-3 weeks, and the association was analyzed with Intraclass Correlation Coefficients. Convergent validity was assessed with related measures administered at Time 1, including the Valuing Questionnaire and measures of general health, well-being, depression, anxiety, and experiential avoidance. Discriminant validity was assessed with an everyday memory questionnaire. Participants completed measures independently, with the assessor providing support as required. Construct validity was analyzed using the multitrait multimethod (at least 75% of Pearson's correlation coefficients in the hypothesized direction). Seventy-four participants completed the initial assessment, and 70 completed the second. Test-retest reliability ranged from excellent (.91) to good (.78) across VLQ-CS scales. Construct validity was supported. As the VLQ-CS performed comparably to the VLQ and was previously found to have superior psychometrics for individuals with ABI, it may offer a more accessible and inclusive measure for use in research and clinical practice across clinical and nonclinical populations.
