12-30% of children present handwriting difficulties, which has negative repercussions on their school career. For this reason, it is fundamental to bet on their prevention. The aim of present study is to examine the effects of a graphomotor intervention program on graphomotor competences in children in the last year of preschool education. This experimental study is a randomized controlled trial. The program will run for 8 weeks (2 sessions/week of 30 minutes), followed by 6 months of follow-up without intervention. Participants will be assessed 1) at baseline, 2) at the end of the program, and 3) after the follow-up. Participants will be randomly allocated to two groups: experimental group (graphomotor intervention program) and control group.

According to estimates, 12 to 30% of children have handwriting difficulties (1), which has negative consequences for school success (2). In addition, this is one of the main reasons for referral and consultation in psychomotricity in school-age (3), which reflects the urgency of acting in this field.

The need for prevention and early intervention is indisputable (4). Several studies indicate that both outweigh the benefits of late intervention, because as time goes on it is increasingly difficult to correct handwriting difficulties (5-6).

Graphomotor skills include the trait, the drawing and the formal handwriting and are related to long and complex learning, which requires several years of learning (7-9).

Today it is known that preschool education represents a very important period for the development of these skills (10). In preschool, children spend 42% of the day on paper and pencil tasks (11) and it is during this period that handwriting readiness skills are developed (12), being a predictor of future school success (12-15). For Beery (16) children are not apt to learn to handwrite without first copying the first nine figures of the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI).

It is based on this that intervention programs have been developed with the aim of promoting the development of handwriting readiness skills in preschool age and of preventing possible handwriting difficulties at school age (14, 17). These intervention programs have shown favourable results in improving the graphomotor skills of preschool children (12, 17-18).

In most cases only something is done, once the handwriting difficulties are installed. In addition, there are few studies dedicated to intervention in graphomotor skills at preschool age and to my knowledge, there is no study whose intervention is based on a psychomotor approach. Based on this, a graphomotor intervention program with a psychomotor approach was developed, by Matias and Vieira (19), who will apply in this study to children in the last year of preschool education.
