Change in the Life Values Questionnaire (VLQ)
The Life Values Questionnaire relates to 10 domains of different life values, which include: family, marriage/intimate partner relationships, parenthood, friendship, work, education, leisure, spirituality, citizenship, and physical self-care. Participants are asked to evaluate on a Likert scale from 0 to 10 the degree of importance they give to these values, where 0 is of little importance and 10 is of great importance. Additionally, they are asked to rate the degree of consistency with which they engage in actions committed to these values, ranging from 0 to 10. Scores are obtained for different sub-scales: importance, consistency, and discrepancy. As a global score for the questionnaire, the composite score is obtained by subtracting the consistency score from the importance score. Higher scores in discrepancy indicates lower levels of value consistency living and worse outcome.
