The relationship between impulsive behavior and alexithymia in pupils / 中华行为医学与脑科学杂志

ABSTRACT

ObjectiveTo 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 elder age group had only significantly higher total score of BIS than pupils in younger age group ( total62.36 ± 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 (total57.43 ± 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％.ConclusionThere 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.
