OBJECTIVE: To identify behavioural and emotional problems in children and adolescents with T1DM.

METHODOLOGY: A cross-sectional study using the Child Behaviour Check List (CBCL) was conducted among all T1DM patients receiving treatment at the Paediatric Endocrine Unit, Hospital Tunku Azizah Kuala Lumpur, Malaysia.

RESULTS: Forty T1DM patients were included. The mean age of the participants was 12.4 years (SD = 2.69), with 52.5% males, and 75% Malay. The average duration of illness was 4.8 years, 9 were pre-pubertal, while mean HbA1c was 9.4%. Thirty-five percent of the respondents had parent-reported internalizing problems and 17.5% had parent-reported externalizing problems. Those >12 years old had more internalizing problems (p = 0.004) compared to those ≤12 years old. The differences were in the anxious/depressed syndrome subscale (p = 0.001) and withdrawn/depressed syndrome subscale (p = 0.015). There were no statistically significant differences in the 3 main global scores by gender, glycaemic control, duration of illness and pubertal status by univariate analysis.
