Gender differences in adolescents' life satisfaction: A replication study in Kazakhstan.

INTRODUCTION Whether adolescents' life satisfaction varies with gender is unclear. In a recently published study, Brisson et al. found unadjusted mean scores of life satisfaction to be higher in boys than in girls in Luxembourg, a country ranking high in gender-equality indexes. However, gender was no longer predictive of life satisfaction when well-identified predictors of life satisfaction were included in the model. The present work aimed to replicate Brisson et al.'s study in Kazakhstan, a less gender-equal country than Luxembourg, and test the gender-equality-paradox hypothesis. METHODS We used cross-sectional data from the Health-Behavior in School-aged Children study conducted in 2022 to mirror Brisson et al.'s study design. We relied on a nationally representative sample of 7369 school attendees in Kazakhstan (MAGE = 13.4; SDAGE = 1.7; 52.3% female). We performed general linear modeling analyses to achieve our research goals. RESULTS AND CONCLUSIONS In keeping with Brisson et al.'s study, we found unadjusted mean scores of life satisfaction to be higher in boys than in girls. The magnitude of the gender gap was lower in Kazakhstan than in Luxembourg. In contrast to Brisson et al.'s study, controlling for well-identified predictors of life satisfaction did not annul the gap in question but changed its sign. This result suggests that, ceteris paribus, girls were more satisfied with their life than boys. Overall, our replication study supports the gender-equality-paradox hypothesis. Future studies may investigate whether this paradox stems from gendered criteria of life satisfaction assessment and/or sociobiological differences in health profiles.
