A validation study of the Multidimensional Life Satisfaction Scale for Children

Area of Science:

• Psychology
• Child Development
• Educational Psychology

Background:

• Life satisfaction in children is linked to vulnerability, discrimination, school environment, relationships, and mental health.
• Growing research interest necessitates reliable psychometric instruments for assessing child well-being.

Purpose of the Study:

• To evaluate the psychometric properties of the Multidimensional Life Satisfaction Scale for Children (MLSS-C).

Main Methods:

• Confirmatory factor analysis (CFA) was used to assess the structural model of the MLSS-C.
• Internal consistency (Cronbach's alpha, composite reliability), test-retest reliability, and construct validity (convergent, divergent) were examined.
• The study involved 379 Brazilian schoolchildren aged 9-14.

Main Results:

• Confirmatory factor analysis supported a six-dimensional structure for the MLSS-C, with five dimensions showing good internal consistency (alpha > .70).
• Convergent validity was supported by positive correlations between life satisfaction, self-concept, and social skills.
• Divergent validity was indicated by a negative correlation between life satisfaction and childhood stress.

Conclusions:

• The MLSS-C demonstrates preliminary evidence of reliability and validity in Brazilian schoolchildren.
• The scale is suitable for research and practical applications involving children in Brazil.
