Condition(s) studied

Investigational drug(s) / intervention(s)

Psychological assessment: Psychological assessment of cognitive, linguistic and social-emotional functioning.

Study 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:

1. Is there a relationship between perinatal factors and risk of occurrence of developmental delay disorder?
2. Is there a specific pattern of cognitive functioning in preschool children with indicated developmental delay disorder?
3. Is there a specific pattern of social-emotional functioning in preschool children with indicated developmental delay disorder?
4. 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:

1. With perinatal risks factors
2. With developmental delay disorder:

1. children with early intervention
2. children with delayed speech development
3. Control group

Eligibility

Primary outcome measure(s)

• Cognitive Functioning Index as measured by the Battery of Methods for the Diagnosis of Psychomotor Development in Children aged 3-6 (B3/6) — 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) — 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) — 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).
