AB  - OBJECTIVE: Most research on personality development has employed self-report 
      questionnaires and concerned individuals older than 10 years. This is the first 
      study to examine mean-level age differences in personality traits from early 
      childhood to late adolescence in the non-Western cultural context. METHOD: 
      Personality was measured in two community samples of parent reports of 
      2-18-year-old children (N = 4,330) and self-reports of 10-19-year-old adolescents 
      (N = 4,663) from Russia by the Inventory of Child Individual Differences-Short 
      version (ICID-S) at the three levels of the hierarchy, the two higher order 
      traits, the Big Five, and lower order traits. RESULTS: Across childhood, the 
      Agreeableness, Conscientiousness, and Neuroticism traits increased, and the 
      Extraversion and Openness traits decreased. In adolescence, parent-reported 
      Conscientiousness traits increased and Neuroticism traits decreased, whereas 
      youth-rated Alpha and Agreeableness decreased in middle adolescence. There were 
      small gender differences in trait levels and age trends. Parents and youths did 
      not agree on gender differences in age trends for Neuroticism and Extraversion. 
      CONCLUSION: The findings support personality maturation from early childhood to 
      late adolescence, with the exception of increasing Neuroticism across childhood, 
      and provide some evidence for the disruption in personality maturation in 
      adolescence. Parents and adolescents may have different perspectives on 
      personality development.
