CALDERON-CARRILLO, Melissa et al. Parents as promoters of language development in premature babies: a proposal for early intervention. Act.Psi [online]. 2018, vol.32, n.124, pp.52-64. ISSN 2215-3535.  http://dx.doi.org/10.15517/ap.v32i124.30449.

Objective: Two scoring systems for a verbal fluency test were compared using the Rasch Rating Scale Model. Method: The analysis was carried out on 289 participants, 92 of whom had had a Parkinson’s disease diagnosis. Scores were calculated with two different category systems: a conventional procedure and a percentile-based one. Results: The percentile-based Rasch scores produce adequate categories and reliable measures, while the correlation with the Mini Mental State Examination evinces concurrent validity. After statistically controlling for age, percentile-based Rasch measures discriminated between both groups, demonstrating predictive validity. Conclusions: The analysis of the two procedures allows for the recommendation of the use of percentile-based categories.

Keywords : Neuropsychological assessment; parkinson’s disease; verbal fluency; Rasch Rating Scale Model.
