Girl students were also inferior to boys concerning the total scores of MHT, learning anxiety, interpersonal anxiety, self-accusation, sensitivity, physical symptoms and impulsive behavior (P < 0.05). The students in Grade 7 scored lower than those of the upperclassmen on MHT (P < 0.05), and the subjects from township were superior to those of rural areas regarding interpersonal anxiety and loneliness (P < 0.05). Children with siblings appeared worse than their counterparts on the total scores of MHT, including the items of interpersonal anxiety, learning anxiety, self-accusation, sensitivity, physical symptoms, strong fear and impulsive behavior (P < 0.05).
