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

Area of Science:

• Psychometrics
• Rehabilitation Psychology

Background:

• The Valued Living Questionnaire-Comprehension Support (VLQ-CS) was adapted for individuals with cognitive and communication difficulties post-acquired brain injury (ABI).
• Its utility in neurotypical populations and comparative psychometric properties with the original VLQ were previously unestablished.

Purpose of the Study:

• To determine the validity and reliability of the VLQ-CS in neurotypical adults.
• To compare the psychometric properties of the VLQ-CS and original VLQ across ABI and neurotypical groups.

Main Methods:

• The VLQ-CS was administered to neurotypical adults via Zoom, with assessments repeated after 2-3 weeks for test-retest reliability.
• Convergent and discriminant validity were assessed using related psychological measures.
• Construct validity was evaluated using the multitrait multimethod approach.

Main Results:

• Test-retest reliability for the VLQ-CS ranged from good (.78) to excellent (.91).
• Construct validity was supported, indicating the measure accurately assesses valued living.
• The VLQ-CS demonstrated comparable performance to the original VLQ.

Conclusions:

• The VLQ-CS is a valid and reliable measure for assessing valued living in neurotypical adults.
• Given its previously established superior psychometrics in ABI populations, the VLQ-CS presents a more accessible and inclusive measurement option for diverse populations in research and clinical practice.
