Abstract:Objective To study the clinical effect of psychological and behavioral intervention combined with biofeedback in the treatment of preschool children with attention deficit hyperactivity disorder (ADHD). Methods Sixty children each with inattentive, hyperactive/impulsive or combined type ADHD were enrolled. According to the intervention measure, they were randomly divided into 4 groups:control, psychological and behavioral intervention, biofeedback treatment and comprehensive treatment (psychological and behavioral intervention + biofeedback). Attention concentration time and impulse/hyperactivity and hyperactivity index scores of the Conners Parent Symptom Questionnaire (PSQ) were evaluated after 4 months of treatment. Results The attention concentration time increased in all types children with ADHD after psychological and behavioral intervention, biofeedback treatment or comprehensive treatment (P < 0.05). In children with inattentive ADHD, hyperactive/impulsive ADHD or combined-type ADHD, biofeedback or comprehensive treatment reduced the impulse/hyperactivity index score (P < 0.05). In children with inattentive or combined-type ADHD, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P < 0.05). In children with hyperactive/impulsive ADHD, biofeedback treatment, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P < 0.05). Conclusions In children with ADHD, psychological and behavioral intervention combined with biofeedback treatment can improve the attention concentration and impulsive/hyperactive and hyperactive symptoms. The treatment strategies are slightly different for children with different types of ADHD.
