Protocol - Early Childhood Speech and Language Assessment - Speech and Language Assessment Scale

Add to My Toolkit
Description:

The Speech and Language Assessment Scale (SLAS) is a 19-item, parent-report questionnaire designed to identify children with delayed speech and language skills. The SLAS uses seven-point Likert-style questions to assess six subscales: assertiveness, responsiveness, semantics, syntax, articulation, and talkativeness. The protocol includes instructions to generate composite scale scores.

Scoring Instructions

Composite scale scores are calculated by adding together the ratings for the items in each subscale and dividing by the total number of items in that scale.

Assertiveness subscale: items 1, 11, 12
Responsiveness subscale: items 2, 13
Semantics subscale: items 5, 6, 10
Syntax subscale: items 14, 15
Articulation subscale: items 4, 7, 16

Assertiveness and responsiveness measure the use of language in social contexts. Semantics measures word learning. Syntax measures grammar. Articulation measures speech sound production and intelligibility.

Detailed instructions on scoring and interpretation can be found in Hadley and Rice (1993).

Life Stage:

Child

Participants:

Parents and caregivers of children ages 3-5

Specific Instructions:
In order for Speech and Language assessments to be considered valid, the investigator should make sure that the respondent speaks English well. The respondent should have hearing and cognitive ability adequate for understanding the items and evaluating the child's speech and language ability. For genetic studies, children should be assessed for hearing or nonverbal impairment as related factors that can contribute to low performance. Language impairment can appear without these factors but if these factors appear, the genetics of the language impairment may be confounded with the genetics of the related factors.
Selection Rationale

The Speech and Language Assessment Scale (SLAS) was selected because it is a short, well-established, validated, parent-report instrument that is easy to use and interpret.
