A longitudinal study on dysgraphic handwriting in primary school

Area of Science:

• Developmental Psychology
• Educational Psychology
• Epidemiology

Background:

• Handwriting is a crucial skill for primary school children.
• Identifying factors contributing to dysgraphic handwriting is important for early intervention.
• Previous research has explored various aspects of handwriting development.

Purpose of the Study:

• To investigate the characteristics associated with dysgraphic handwriting in primary school children.
• To identify developmental trajectories of handwriting skills over five years.
• To explore the relationship between fine-motor ability, structural performance, stylistic preference, and dysgraphia.

Main Methods:

• An epidemiological study followed 121 Dutch primary school children for 5 years, starting in Grade 2.
• Handwriting scripts were evaluated annually using the BHK scale, assessing 13 characteristics and writing speed.
• Principal component analysis was applied to identify underlying factors in handwriting performance.

Main Results:

• Dysgraphic handwriting (top 10% on BHK quality) was associated with lower fine-motor ability.
• Children with dysgraphia showed poorer structural performance and less stylistic preference in higher grades.
• No significant differences in writing speed were found between children with and without dysgraphic handwriting.

Conclusions:

• Fine-motor ability and stylistic preference are key factors differentiating dysgraphic from typical handwriting.
• The findings suggest specific areas for targeted handwriting instruction.
• Early identification and intervention focusing on motor skills and style may benefit children at risk for dysgraphia.
