summary
The MacArthur-Bates Communicative Development Inventories (MB-CDIs) are instruments that can be used to measure a child’s early language development across a variety of abilities including vocabulary comprehension, production, gestures, and grammar.
3 Age-Based Versions Available:
-
- Infant: 6-18 months
-
- Receptive vocabulary
- Expressive vocabulary
- Communicative gestures
- Symbolic gestures
-
- Toddler (18-30 months):
-
- Productive vocabulary
- Early phases of grammar
-
- Children (30-37 months)
-
- Vocabulary production
- Grammar
-
- Infant: 6-18 months
Norms Across All Groups Accessible By:
-
- Total group
- Age of identification
- By degree of hearing loss
- By cognitive level
- By age of identification and cognitive level
Administration Format: parent report; web-based database available for scoring and interpretation
Administration: 20-40 minutes | Scoring: 10-15 minutes | Total Time: 30-55 minutes
Reliability (Dale 1989):
-
- Internal Consistency: good (alphas ranged from 0.67-0.96)
- Test-Retest: good (alphas ranged from 0.86-0.95)
Validity (Dale 1989): tests using Bayley Scales of Infant Development suggested correlations across MDI vocabulary measures, consistent with a four month delay between parent report and standardized test.
