Abstract

CRESTANI, Anelise Henrich; MORAES, Anaelena Bragança de; SOUZA, Adriano Mendonça  and  SOUZA, Ana Paula Ramos de. Construct validation of enunciative signs of language acquisition for the first year of life. CoDAS [online]. 2020, vol.32, n.3, e20180279.  Epub June 15, 2020. ISSN 2317-1782.  http://dx.doi.org/10.1590/2317-1782/20202018279.

Purpose:

To perform the construct validation of enunciative signs of language acquisition for children aged 3 to 12 months.

Method:

The study sample consisted of 94 mother-infant dyads for the analysis of Phase 1 (3-6 months) signs and 61 dyads for the analysis of Phase 2 (7-12 months) signs. Data collection was performed through analysis of the interaction between mothers and infants in play situation recorded in 15-min videos in the predicted phases, with attribution of value types of present or absent to each sign analyzed. The collected data were organized on a spreadsheet and then converted to computer applications for factor analysis.

Results:

Factor analysis indicated the existence of two factors named “mother” and “infant” both for Phase 1 signs (explaining 71.9% of the variation) - with three signs relevant for the “infant” factor and one sign relevant for the “mother” factor, and for Phase 2 signs (explaining 74.4% of the variation) - with one sign relevant for the “infant” factor and one sign relevant for the “mother” factor.

Conclusion:

Construct validation showed that one “mother” factor and one “infant” factor were able to distinguish between at-risk and not-at-risk groups in both phases analyzed, which suggests that the absence of these signs may pose risks to language acquisition.
