Area of Science:

Developmental Psychology
Speech-Language Pathology
Quantitative Research Methods

Background:

Generalizability and decision studies offer a mathematical framework for measurement stability.
Assessing communicative behavior in young children requires reliable and representative measures.
Existing debates question which assessment type yields the most representative scores.

Purpose of the Study:

To conduct a generalizability and decision study on toddlers with developmental delay.
To quantify the stability of communication and vocabulary measures over time and across contexts.
To evaluate the impact of an intervention targeting communication and vocabulary goals.

Main Methods:

A generalizability and decision study was performed on 63 toddlers with developmental delay.
Participants received a 6-month intervention focused on communication and vocabulary.
Two variables (rate of intentional communication acts, rate of different words) were measured across three contexts and four sampling periods.

Main Results:

Measurement stability for both intentional communication acts and different words increased over time.
Developmental progress positively influenced measurement stability.
The type of assessment procedure did not significantly affect measurement stability.

Conclusions:

Generalizability and decision studies provide a robust framework for evaluating measurement reliability in pediatric populations.
Measurement stability in young children's communicative behavior improves with time and development.
The findings support the use of these studies as an alternative to traditional assessment debates.
