The assessment of children's quality of life presents specific methodological aspects. The objective of this study was to examine the psychometric properties of the Portuguese version of the Child Quality of Life Systemic Inventory (CQLSI). It is based on an innovative conceptual and methodological approach to quality of life self-assessment. It is interactive and playful, has a psychometry which operates several scores, and allows the analysis of each domain of life. One hundred twenty Portuguese children, from 8 to 12 years old, participated in the study. Results show that internal consistency of the four scores of the CQLSI (State, Goal, Rank and Gap) is satisfactory and all scores have their own specificity. Findings reveal the feasibility of this self-assessment instrument for children's quality of life, demonstrating psychometric adequacy of the Portuguese version.
