Efficacy of an Intervention to Teach Zippering: A Two-Group Control Study

Not Applicable

Completed

• Conditions: Typical Preschoolers Who Can Not Zipper
• Interventions: Behavioral: Standard zippering vest; Behavioral: Modified zippering vest

• Registration Number: NCT04185324
• Lead Sponsor: Salus University

Brief Summary

Preschoolers are assigned to a control group or a comparison group to examine the efficacy of a new intervention to teach the skill of engaging and pulling up a zipper.

Detailed Description

Purpose: This pilot study compares the efficacy of a standard teaching zippering vest presented with general verbal prompts to a modified teaching zippering vest presented with a related story and vocabulary in the acquisition of zippering skills among typically developing preschoolers. Institutional Review Board approval and parent consent was obtained.

Design: An experimental two group pre-post test design was used. Setting: Research occurred in a local preschool. Participants: Participants were recruited from fifty 3.6-to 4.11-year-old preschoolers.

Intervention: Eligible children received 3 zippering practice sessions with either a standard zippering vest (control group) or a modified vest with added visual and language cues (comparison group).

The treatment protocol for both cohorts of participants was administered over a three-week time period to minimize the impact of normal development.

Arm && Interventions

Group	Intervention	Description
Standard zippering vest	Standard zippering vest	Children receive three supervised sessions for them to practice engaging and pull up a zipper, using a standard teaching zippering vest.
Modified zippering vest	Modified zippering vest	Children receive three sessions of specially designed zippering instruction using a modified zippering vest, where they can practice engaging and pulling up a zipper after being read a related story.

Primary Outcome Measures

Name	Time	Method
Zippering steps completed	all data was collected within three weeks for each child to minimize the impact of typical development	The task of engaging and pulling up a zipper was broken down to 7 steps. By examining video data, the number of zippering steps completed was analyzed for each zippering trial.
