小学生冲动行为与述情障碍的关系研究

The relationship between impulsive behavior and alexithymia in pupils

目的研究小学生冲动行为与述情障碍之间的关系。方法采用Barratt冲动性量表（BIS－11）和多伦多述情障碍量表（TAS－20），对702名小学生进行测评，分别评估他们的冲动行为和述情障碍。结果（1）男生在无计划因子和冲动总分的得分上高于女生[（24．47±5．30）分，（23．40±5．59）分，P〈0．05；（62．25±9．46）分，（60．35±9．91）分，P〈0．05]。高年龄组仅在冲动总分上的得分均高于低年龄组[（62．36±9．69）分，（60．29±9．68）分，P〈0．01]。（2）高冲动者在述情障碍总分及各因子上的得分均高于低冲动者[述情障碍总分（57．43±10．16）分，（46．55±8．77）分，P〈0．01]；BIS总分与述情障碍量表总分存在正相关（r＝0．40，P〈0．01）；BIS总分与述情障碍各因子亦有正相关（r=0．25—0．33，均P〈0．01）；逐步回归分析显示，辨别情感障碍、外向性思维、描述情感障碍对冲动总分均有显著的回归效应，可以解释18％的冲动总分变异。结论8～13岁儿童的冲动行为存在一定的性别和年龄差异；儿童的冲动行为与述情障碍存在低至中序相关。

Objective To study the relationship between impulsive behavior and alexithymia in pupils in Changsha. Methods 702 pupils were tested with Barratt impulsivity scale （BIS-11） and Toronto alexithymia scale （TAS-20）. Results （ 1 ） Male pupils had significantly higher scores of total BIS and non-planning impulsiveness than female （ 24.47 ± 5.30 vs 23.40± 5.59, P 〈 0.05 ; 62.25 ± 9.46 vs 60.35 ± 9.91, P 〈 0.05 ）. Pupils in eider age group had only significantly higher total score of BIS than pupils in younger age group （total： 62.36 ± 9.69 vs 60.29 ± 9.68, P 〈 0.01 ）. （ 2 ）Pupils with high impulsivity had significantly higher scores of total and factor scores of alexithymia than pupils with low impulsivity （ total： 57.43 ± 10.16 vs 46.55 ± 8.77, P 〈 0.01 ）. The total scores of BIS were positively correlated with total scores of alexithymia （ r = 0.40, P 〈 0.01 ） and factor scores of alexithymia （ r = 0.25 ±0.33, P 〈 0.01 ）. Stepwise regression analysis revealed that total scores of BIS explained by DIF,DDF and EOT were 18%. Conclusion There are certain gender and age differences in impulsivity impulsive behavior of 8 to 13 years old pupils. There exist the low to moderate correlations between impulsivity and alexithymia in pupils.
