Assessment of adolescent optimism: Measurement invariance across gender and race/ethnicity

Optimism is viewed as an important resource for resilience and is associated with various wellbeing outcomes, yet few measures of optimism have been validated for use with adolescents. The aim of this study was to (a) test the factor structure invariance of the School Success Profile Success Orientation scale across gender and four racial/ethnic groups and (b) estimate group-level differences in optimism.

Data from a diverse sample of adolescents (N = 2063; mean 12.3 years; 52% female) from the southeastern United States were examined using multiple-group confirmatory factor analysis. Models for configural, metric, and scalar invariance were tested using WLSMV estimation in Mplus.

Confirmatory factor analysis supported the hypothesized one-factor model and indicated scalar invariance across gender and the four racial/ethnic (i.e., African American, Caucasian, Hispanic/Latino, Native American) groups. Cross-group comparisons of latent factor means indicated statistically significant differences in self-reported optimism. Female respondents reported higher optimism than males. Among the four racial/ethnic groups, African American youth reported the highest optimism levels. Native American youth reported higher optimism than Caucasian and Hispanic/Latino youth.

Results suggest the Success Orientation scale is appropriate for many assessment and evaluation purposes, including the assessment of optimism across gender and race/ethnicity and the investigation of substantive questions regarding cross-cultural differences in adolescents' expectations of the future.
