Trial Outcomes & Findings for Efficacy of AMALS in Treating Language Impairment in Children (NCT NCT00840060)

NCT ID: NCT00840060

Last Updated: 2012-05-15

Results Overview

Samples were transcribed and segmented by utterance. Each was coded categorically. Reported measures include percentage of utterances at the interpretive/inferential label, percentage of utterances with one or more t-unit (i.e., noun phrase + verb phrase), percentage of utterances that required copula (is/are) or auxiliary (is/are) that were produced.

Participant Flow

Children were recruited at three public school sites. From January 2009 to May 2010, 50 participants were successfully recruited. Of the 50, 40 met inclusion criteria and were randomly assigned to one of the two treatments.

No participants were excluded from the treatment following enrollment.

Addressing Multiple Aspects of Language Simultaneously
Children assigned to this treatment group participated in language treatment that followed a scaffolded-language structure. Linguistic content and structures were not explicitly targeted.
Discrete Trial Approach
Children assigned to this treatment group participated in a language treatment following an additive structure. Linguistic content and structure were explicitly targeted.

PRIMARY outcome

Timeframe: Language samples were obtained pre-treatment, post-treatment, and at one-month follow-up.

Population: Language samples were collected for all children participating in either treatment condition.

Samples were transcribed and segmented by utterance. Each was coded categorically. Reported measures include percentage of utterances at the interpretive/inferential label, percentage of utterances with one or more t-unit (i.e., noun phrase + verb phrase), percentage of utterances that required copula (is/are) or auxiliary (is/are) that were produced.

PRIMARY outcome

Timeframe: Pre-treatment, post-treatment, 1-month follow-up

Samples were transcribed and segmented by utterance. Utterances were analyzed for novel verb structures. Structures were included if they were produced more than one time.
