【Objective】 To explore the influencements on children's behavioral problems at the same period and two years later, and to explore the stability of behavioral problems, in order to provide effective rearing patterns to reduce behavioral problems. 【Methods】 Two children temperament questionnaires(TTS, BSQ) developed by Carey were administered to 2~3 year-old children taken at random in 5 districts of Beijing countryside whose development screening was normal, and the Child-rearing Practice was investigated to test the rearing pattern, Child Behavior Checklist(CBCL 2~3,4~16) were used to test the behavioral problems. 【Results】 1)Temperament was the most important risk factor to children's behavior problems, especially on internalizing behavior problems; parents' rearing pattern was another risk factor; the situation of pregnant of mothers could effect on externalizing behavior problems; 2)The rhythmicity of children's temperament and rejection of parents' rearing pattern could predict children's behavioral problems after two years; 3)There was significant stability in externalizing behaviors, but less stability in internalizing behaviors. 【Conclusions】 children's temperament and parents' rearing pattern can impact on children's behavioral problems at the same period and two years later, there were stability on children's behavioral problem.
