ObjectiveTo explore the effect of mental toughness level on positive and negative emotion and mental health in children with epilepsy.MethodsIn accordance with the International League against epilepsy and epilepsy syndrome in 1989 International Classification of young children with epilepsy,160 cases were sampled.Based on the Adolescent Resilience Scale ( HKRA ) score,according to the 27％ principles of delimitation,the patients were divided into high HKRA score group and low HKRA score group,43 cases in each group.Then positive emotions and negative affect scale (PANAS),mental health test (MHT) were applied to two groups.Results,Except family support dimension,the others HKRA dimension and total score were higher in female children with epilepsy than those in male patients,there was significant difference (P＜ 0.01 ).The positive affect score were higher in high HKRA score group than that of low HKRA group ; and negative emotion was significantly lower than that in low HKRA group (P＜ 0.01 ).Except physical symptom dimension,other dimensions and total score of HKRA in high HKRA score group were higher than those in low HKRA group,there was significant difference (P＜ 0.01 ).Children with epilepsy HKRA score was positive correlation with positive emotion score but negative correlation with negative affect scores (P ＜ 0.01 ) ; in addition to physical symptom,HKRA score and MHT score,and all the other dimensions were negatively related (P＜0.01 or 0.015).ConclusionThe mental toughness level are significantly related to children's epilepsy patients with positive and negative emotion and mental health status.A high level of mental toughness can increase positive emotional experience,and reduce the negative emotional experience of children with epilepsy.
