Purpose: To present evidence of intra- and inter-rater reliability and internal consistency of the Phonological Assessment Instrument scores, so that it can be considered reliable and valid for use in clinical practice.
Methods: 179 audio recordings of the instrument's speech samples were analyzed. The collection was carried out from its application in the period of 5 months in children aged from five to eight years and 11 months.
Purpose: To investigate evidence of construct validity for a Phonological Assessment Instrument for Brazilian Portuguese, based on the diagnostic data generated by its application from contrastive analysis and speech severity.
Methods: The sample consisted of 176 children, aged between five to nine years old. They were evaluated with the Phonological Assessment Instrument and then classified as having Speech Sound Disorder or in typical phonological development, comparing these results to the criteria described for the disorder in the DSM-5.
Purpose: to demonstrate the validity of content and the validity of response processes of an instrument intended for the phonological assessment of children.
Methods: validation was carried out in two stages by two different groups of judges, a group of specialists and a group of non-specialists. The first group, composed of three expert judges, evaluated the 123 lexical items after creating the instrument, judging the applicability of the figures in the context of child assessment, and suggesting adjustments to compose the content.
