Overview
Brief Summary
The goal of this observational study is to investigate perinatal, cognitive, linguistic and social-emotional correlates of developmental delays of preschool children.
The study group consist of minimal 500 children between 3 and 6 years of age who will be examined by qualified diagnosticians. Participants will be evaluated with tasks related to the studied variables: cognitive functioning, linguistic skills and social-emotional functioning. Furthermore informations regarding social-emotional functioning of children, will be collected from parents.
The main questions it aims to answer are:
- Is there a relationship between perinatal factors and risk of occurrence of developmental delay disorder?
- Is there a specific pattern of cognitive functioning in preschool children with indicated developmental delay disorder?
- Is there a specific pattern of social-emotional functioning in preschool children with indicated developmental delay disorder?
- Do gender and age moderates specific patterns of cognitive and socialemotional functioning in the studied groups?
Researchers will compare the following groups of children between 3 and 6 years old:
-
With perinatal risks factors
-
With developmental delay disorder:
-
children with early intervention
-
children with delayed speech development
-
Control group

Outcomes
Primary Outcomes
Cognitive Functioning Index as measured by the Battery of Methods for the Diagnosis of Psychomotor Development in Children aged 3-6 (B3/6)
Time Frame: Baseline
The Cognitive Functioning Index is a composite score derived from the Cognitive Area of the B3/6 battery. It evaluates visual-spatial processing (Blocks, Puzzles), working memory (Frog recall tasks, Sentence repetition), planning (Mazes), and naming speed. Data will be reported as a standardized score (mean=100, SD=15).
Phonological Processing Index as measured by the Battery of Methods for the Diagnosis of Psychomotor Development in Children aged 3-6 (B3/6)
Time Frame: Baseline
Description: This index assesses linguistic skills through the Phonological Processing scale of the B3/6 battery. It includes tasks measuring syllabic and phonemic analysis and synthesis, as well as sound abstraction. Data will be reported as a standardized score (mean=100, SD=15).
Social-Emotional Development Score as measured by the Battery of Methods for the Diagnosis of Psychomotor Development in Children aged 3-6 (B3/6)
Time Frame: Baseline
Description: This score evaluates the child's social-emotional competence through the Social-Emotional Area of the B3/6 battery. The assessment covers three key components: naming emotions, recognizing emotions, and empathy. Data will be reported as a standardized score (mean=100, SD=15).
Secondary Outcomes
- Occurrence of perinatal complications(Baseline (retrospective data))
- General intellectual functioning measured by the Stanford-Binet 5 (SB5)(Baseline)
- Nonverbal Intelligence Quotient (NIQ) as measured by the Primary Test of Nonverbal Intelligence (PTONI)(Baseline)
- Early social-emotional development(Baseline)
- Birth weight(Baseline (retrospective data))
- Gestational age at birth(Baseline (retrospective data))
- Apgar score(Baseline (retrospective data))
- Socio-demographic data(Baseline)
