Behavioural difficulties and quality of life in children with borderline intellectual functioning: A study of self- and parent-reported discrepancies in Thailand.

Background: Borderline intellectual functioning (BIF) involves cognitive and adaptive limitations affecting behaviour and quality of life (QoL). This study compared self- and parent-reported behavioural difficulties and QoL in Thai children with BIF and identified associated factors.

Method: Fifty children aged 8-15 years with BIF and their parents completed the Strengths and Difficulties Questionnaire and Pediatric Quality of Life Inventory. Differences between child and parent reports were analysed using paired t-tests. Predictors of QoL were analysed using hierarchical multiple regression.

Results: Parents reported fewer conduct problems, peer problems, and total difficulties than children, while rating prosocial behaviours higher. Self-reported QoL scores were higher, especially in social and school domains. Lower self-reported difficulties and lower paternal education predicted higher self-reported QoL, while higher maternal education and IQ predicted better parent-reported QoL.

Conclusion: Discrepancies between self- and parent-reported outcomes highlighted the importance of integrating both perspectives in care planning for children with BIF.
