| Popis: | This longitudinal study was designed to examine the CDI-WORDS Short Form vocabulary checklist (Reznick & Goldsmith, 1989) as an index of language production. In particular, we were curious about: (1) the concurrent associations between the CDI-WORDS Short Form checklist measure and directly observed measures of lexical production; (2) the associations between Short Form checklists administered at different ages; and (3) the predictive associations between Short Form scores and subsequent measures of more general intellectual abilities (i.e. the Wechlser Preschool and Primary Scale of Intelligence; WPPSIR; Wechsler, 1989). In a sample of 32 children, significant correlations were found between CDI-WORDS Short Form scores and directly observed measures of lexical production at both 1;6 and 2;0. Further, both the Short Form checklist and the observed measure of lexical production were found to predict WPPSI-R Verbal IQ scores but not the Performance IQ scores at 4;0. Additional analyses demonstrated the predictive and convergent validity of the CDI-WORDS Short Form, and underscored the additional value of direct observational measures of lexical production during early lexical development. |
