Description This study evaluates the psychometric properties of the Stirling Scale of Child Well-Being (SCWBS) and focuses on its ability to assess the well-being of children and preadolescents accurately. It examines the scale structure and item specifics, and highlights the need for a model based on existing research. Using a sample of 1701 fourth- and sixth-grade students, the study compares the unidimensional, two-factor, and bi-factor models of the SCWBS through item response multivariate theory, culminating in a thorough item analysis of the selected model. Findings indicate that the unidimensional model is the most appropriate for measuring well-being in the target age group, supporting the SCWBS for assessing overall, rather than subjective or psychological, well-being. The study confirms the robust psychometric validity of the unidimensional model and suggests a three-point Likert scale for younger respondents to increase the accuracy of responses.
