Observational Tokat Gaziosmanpasa University · NCT05749718

This study is testing a new tool to see if it can help understand how babies with motor delays, who are between 7 to 16 months old, develop their understanding of object permanence in a way that fits Turkish culture.

What this trial studies

This study focuses on adapting the Object Permanence Scale for Turkish-speaking populations and assessing its reliability and validity. It targets infants aged 7 to 16 months who exhibit motor developmental delays, specifically those who can sit for at least 3 seconds but cannot transition independently between positions. Evaluations will be conducted at baseline and again after one week to ensure consistency in results. The study aims to provide a culturally relevant tool for assessing developmental delays in this age group.

Who should consider this trial

Good fit: Ideal candidates for this study are infants aged 7 to 16 months with specific motor developmental delays.

Not a fit: Patients with severe medical complications or diagnosed conditions such as autism or Down syndrome may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable assessment tool for identifying developmental delays in Turkish infants.

How similar studies have performed: While similar studies have been conducted in other cultural contexts, this specific adaptation for Turkish infants is novel.
