The aim of the present study was to compare the relations between subtypes of social withdrawal and socio-emotional adjustment in Chinese children and early adolescents. Participants included 571 children (M
age = 9.62 years) and 345 adolescents M
age = 12.12 years) in mainland China. Social withdrawal subtypes (i.e., shyness, unsociability, social avoidance) and indices of socio-emotional adjustment were assessed via self-reports, peer nominations, and teacher ratings. Shyness tended to be more strongly associated with emotional maladjustment in early adolescence, whereas unsociability was more strongly associated with socio-emotional difficulties in childhood. For social avoidance, associations with indices of negative adjustment (i.e., social anxiety, emotional symptoms, peer problems) were stronger in childhood, however, associations with indices of positive adjustment (i.e., life satisfaction, well-being) were stronger in early adolescence.
