Background
The Infant-Toddler Checklist (ITC) is an early developmental screening questionnaire designed to identify communication and social-developmental differences in infants and toddlers.
The questionnaire focuses on important early developmental areas such as eye contact, emotional interaction, gestures, sounds, language development, understanding, and play behaviors.
The ITC is commonly used by parents, caregivers, pediatric professionals, and early childhood specialists to monitor developmental milestones and identify children who may benefit from additional developmental evaluation or support.
The questionnaire explores several important developmental areas:
- Emotion and Eye Gaze
- Communication
- Gestures
- Sounds
- Words
- Understanding
- Object Use
Emotion and Eye Gaze measures social attention, emotional connection, eye contact, and shared interaction.
Communication measures the child's ability to seek help, gain attention, and socially interact with others.
Gestures measure nonverbal communication skills such as pointing, showing, waving, and shared interaction.
Sounds and Words measure speech development, vocalization, and early language growth.
Understanding measures receptive language and the ability to respond to spoken words and phrases.
Object Use measures play skills, pretend play, object understanding, and developmental interaction with toys and everyday objects.
The ITC is designed as an early developmental screening tool and should not be used as a standalone diagnostic instrument.
Procedure
Instructions:
This questionnaire is designed to be completed by parents, caregivers, teachers, or professionals who regularly observe the child.
Please answer each question based on the child's usual communication, social interaction, gestures, sounds, understanding, and play behaviors.
Participants rate each statement using response options that best describe the child's current developmental behaviors and abilities.
Participation
This assessment is designed for infants and toddlers and is intended for educational, research, and developmental screening purposes only.
Results should not be considered a clinical diagnosis or substitute for a professional developmental, medical, or psychological evaluation.
Scoring & Interpretation
Responses are scored based on developmental frequency and ability levels. Higher scores generally indicate stronger developmental communication, social interaction, gesture use, and language-related abilities.
The ITC is commonly used as an early developmental screening instrument to help identify children who may benefit from additional developmental evaluation or early intervention support.
