Urban Turkish children's performance on the Denver Developmental Screening Test

Area of Science:

• Pediatric developmental assessment
• Child psychology
• Cross-cultural developmental studies

Background:

• The Denver Developmental Screening Test (DDST) is widely used to assess child development.
• Previous studies indicate minor sex differences in DDST performance.
• Limited research exists on socioeconomic influences on DDST in diverse cultural contexts.

Purpose of the Study:

• To analyze sex and social-class differences in DDST performance among healthy, urban Turkish children.
• To investigate potential cultural variations in developmental trajectories.
• To evaluate the appropriateness of standardized DDST norms for the Turkish population.

Main Methods:

• Analysis of normative data from 1176 healthy, urban Turkish children.
• Comparison of DDST performance based on sex and socioeconomic status.
• Statistical evaluation of developmental differences across age groups.

Main Results:

• Minor sex differences in DDST performance were observed, consistent with international findings.
• Significant social-class differences emerged, favoring more advantaged children from 10 months onward.
• These disparities were most pronounced in language and fine-motor skills with increasing age.

Conclusions:

• Socioeconomic factors create substantial cultural differences in child development within urban Turkey.
• A single set of DDST norms may lead to misdiagnosis in this population.
• The predictive validity of the DDST is questionable for lower-class urban Turkish children, especially for language and fine-motor tasks.
