Reliability and Validity of the Turkish Version of the Object Permanence Scale

Recruiting

• Conditions: Developmental Delay

• Registration Number: NCT05749718
• Lead Sponsor: Tokat Gaziosmanpasa University

Brief Summary

The aim of the study is the cultural adaptation of the Object Permanence Scale to Turkish and to examine its validity and reliability. The sample of the study will be 7-16 months old babies with motor developmental delay. Inclusion criteria: 7-16 months of age, sitting for at least 3 seconds but not being able to switch independently between sitting and other positions, and showing at least one developmental delay in the motor development subscale of the Bayley III Developmental Assessment. Evaluations will be done at baseline and after 1 week (retest). Exclusion criteria: Medical complications (eg, severe visual impairment) limiting participation in assessments; autism, down syndrome, or spinal cord injury; diagnosed uncontrolled seizure disorder; or a neurodegenerative disorder.

Primary Outcome Measures

Name	Time	Method
Object Permanence Scale	After 1 week (retest)	The minimum score of the Object Permanence Scale is 0, and the maximum score is 10. Higher scores indicate better outcome.
The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) motor and cognitive subscales	Baseline	Cognitive subscale consists of 91 items and Motor subscale consists of 138 items. Items are scored as 1 (done) and 0 (not able to). Higher scores indicate better outcome.
Gross motor function measure sitting subscale	Baseline	The sitting subscale consists of 20 items. Each item is scored on a 4-point ordinal scale (0-3). Higher scores indicate better outcome.
