Investigation on behavior problems and influencing factors of urban left behind and non left behind children in Harbin

Objective To determine the differences and influencing factors of the behavior problem among left-behind children and non-left-behind children aged 4-5 years and to provide a theoretical basis for prevention intervention in Harbin.Methods In November-December 2016, a case-control study was conducted to select 208 left-behind children aged 4-5 years from 12 kindergartens in Harbin and 208 non-left-behind control subjects frequency were matched by class, gender and birth date (within 3 months), the selected 416 child guardians conducted a questionnaire survey.The questionnaire includes: general information about children, Achenbach, Child Behavior Checklist, Family Assessment Device and so on.Results The detection rates of behavioral problems of children in left-behind group and non-left-behind group were respectively 20.2% and 15.9% (χ2= 1.32, P = 0.25); but in left-behind group girls' behavior problem detection rate (26.7%) was higher than the boys ' behavioral problems detection rate (13.6%) (χ2= 5.515, P = 0.019).There was no significant difference in behavior problem scores between left-behind group (26.78±30.22) and non-left-behind group: (26.78±30.22) (t = 1.73, P = 0.085); but the differences in thinking problem and aggressive behavior scores were statistically significant (Thinking Problem: t = 2.23, P = 0.023; Aggressive Behavior: t = 2.30, P = 0.02).There was a significant positive correlation between the dimensions of the family function and the children's thinking and aggressive behavior in the left-behind group; the role function had a significant positive correlation with the aggressive behavior.The regression coefficients of communication dimension and role dimension on left-behind children 's thinking problems were respectively 0.203 and0.238.The regression coefficients of the family function role dimension and the behavior control dimension on the aggressive behavior of left-behind children were respectively 0.269 and 0.175; The regression coefficient of the family function role dimension on aggressive behavior of non-left-behind children were 0.172.Conclusion Left-behind group of child thinking problem and aggressive behavior problems are more serious than non-left-behind, the behavior problems occur between left-behind and non-left-behind children is related to family dysfunction.
