Developing a brief cross-culturally validated screening tool for externalizing disorders in children.

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Behavioral Science

Background:

• Existing screening tools for externalizing disorders are primarily developed for Western populations.
• There is a need for culturally sensitive screening instruments applicable to diverse child populations.

Purpose of the Study:

• To develop and validate a brief teacher-based screening instrument for predicting externalizing disorders in both native Dutch and non-Dutch immigrant children.
• To assess the predictive accuracy of the instrument across different ethnic groups.

Main Methods:

• Teachers completed the Strengths and Difficulties Questionnaire for 2,185 children (ages 6-10).
• A subsample underwent detailed interviews for diagnostic assessment.
• Logistic regression analysis was used to derive a prediction score from specific questionnaire items.

Main Results:

• Four items (restless, obeys, lies, concentrates) effectively predicted externalizing disorders.
• The screening tool demonstrated good discriminatory power (AUC = 0.84).
• No significant differences in prediction accuracy were found between native Dutch and non-Dutch immigrant children.

Conclusions:

• A concise, teacher-assessed scoring rule can predict externalizing disorders in diverse child populations.
• The developed tool shows promise for early identification of externalizing disorders.
• External validation is required before clinical implementation.
