Purpose:
To evaluate the psychometric properties of the naming and imitation tasks of the Digital Speech Assessment Instrument.
Methods:
Forty-five Brazilian Portuguese (BP)-speaking children aged 4 to 9 years, with and without Phonological Disorder (PD) participated in the study. Construct validity was verified by convergent validity, criterion validity was analyzed using Student's t-test for independent samples, and inter-rater reliability was assessed.
Results:
The naming task demonstrated satisfactory construct validity. In the imitation task, correlations ranged from moderate to nearly perfect. Both tasks discriminated well between groups, with children with PD presenting consistently lower scores. Inter-rater agreement was substantial to nearly perfect.
Conclusion:
The results indicate that the naming and imitation tasks of the Digital Speech Assessment Instrument are valid and reliable.

Common Names of Aldehydes and Ketones
Common names of aldehydes are derived from the names of their corresponding acid. For instance, the two-carbon aldehyde–acetaldehyde derives its name from the corresponding acid–acetic acid. Similarly, formaldehyde derives its name from formic acid and benzaldehyde from benzoic acid.
