Text Box: PRELIMINARY RESEARCH OF THE CHARACTERISTICS OF IN-HOSPITAL CHILDREN’S PSYCHOLOGY AND BEHAVIOUR Gu Ying Children’s Hospital of Fudan University, Shanghai, China Objective: To explore the characteristics of in-hospital patients’ psychology & behaviour, as well as the affecting factors. Methods: 49 in-hospital patients aged between 4-14 were interviewed, using Achenbach Children Behaviour Instrument (CBCL) and Family Assessment Device Instrument (FAD). At the same time, in-depth interviews were conducted toward 13 patients’ caregivers. The in-depth interview topics covered patient’s hospital experience, emotion & behaviour change. Chi-square test & multiple factors Anova were used to analysis the data. Results: Internal Consistency Reliability of this instrument was 0.94. Based on this instrument’s screening criteria, 30.5% of the in-hospital patients scored higher than standard value. The behaviour of attack & violate were significantly affected by the factors of Congenital Heart Disease (CHD), Age Group & Gender. These 3 factors also significantly correlated with some test- items in the instrument. The CHD patients’ family have more communication problem than other families. Conclusions: Compared with healthy children, in-hospital patients show more behavioural problems. Male patients performed worse than female patients on the behaviour of violate & attack. Due to the development of cognisance, patients after 7 years old seemed to have more psychological & behaviour problems than the younger ones. 2371
