Study summary

The aim of the study is the examining responsiveness of the Object Permanence Scale. 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 3 months. 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.

What researchers measure

Primary outcomes

  1. Object Permanence Scale

    The minimum score of the Object Permanence Scale is 0, and the maximum score is 10. Higher scores indicate better outcome.

    Time frame: Baseline

  2. Object Permanence Scale

    The minimum score of the Object Permanence Scale is 0, and the maximum score is 10. Higher scores indicate better outcome.

    Time frame: 3rd month

  3. The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) motor and cognitive subscales

    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.
