Abstract:Objective To explore the effects of psychological intervention on therapeutic pain in 70 cases of hospitalized 7~13yearsold children with different personality characteristics. Methods 70 cases of hospitalized noncritically ill children patients were randomly selected for the study. The pain assessment after venipuncture was conducted in the 1st day and 5th day by selfevaluation and preceptor evaluation; the personality traits were evaluated with Junior Eysenck Personality Questionnaire (JEPQ) in the 1st day after admission; with psychological intervention between the 2nd and 5th days. Therapeutic pain intensities of the children with introvert,extrovert,and ambivert personality traits and children with stable and unstable emotions in the 1st and 5th days after admission (before and after admission) were compared. Results Therapeutic pain intensities tended to alleviate with psychological intervention and ongoing hospitalization days; particularly in the introvert and ambivert children and the children with stable and unstable emotions,comparison of therapeutic pain intensities before and after psychological intervention were statistically significant (P<0.05). Conclusion Psychological intervention could alleviate therapeutic pain in children,particularly in introvert and extrovert children; and therapeutic pain intensities in children with stable and unstable emotions could be relieved by psychological intervention.
