Exploring the feasibility and effectiveness of a naturalistic family centered intervention to enhance early interactions in toddlers with Down syndrome
(2025) Mendoza-García, Ana; Aparicio, Andrés; Arango, Paulina Sofía; Tenorio, Marcela
This study analyses the feasibility and effectiveness of BabyMICARE, a manualised intervention programme aimed at improving the interactions between caregivers and infants and toddlers with Down syndrome. The programme’s goal is to enhance caregivers’ sensitivity and reduce directivity during early interactions, particularly during play and daily routines. A pre-test and post-test design was used with 40 dyads of infants with Down syndrome and their caregivers, who were divided into a control group (n = 20) and an intervention group (n = 20), based on baseline scores in key interaction subscales. Sessions were conducted over 10 weeks by trained psychologists. Parent-infant interaction was assessed using the MACI coding system, which measures aspects such as sensitive responsiveness, directivity and the level of reciprocity between the parent and the child. The programme showed high feasibility, with a 100% attendance rate but some rescheduling. Caregivers evaluated it positively. The intervention group demonstrated significant improvements in five of eight MACI scales, particularly in sensitive responsiveness and nondirectiveness, while no changes were observed in the control group. The results suggest that BabyMICARE is a feasible and effective intervention for promoting more responsive, less directive interactions, which may be crucial in fostering children’s development.
Standardization and diagnostic utility of the Frontal Assessment Battery for healthy people and patients with dementia in the Chilean population
(2022) Grandi, Fabrissio; Martínez, David; Parra, Mario; Olavarria, Loreto; Huepe, David; Alegría, Patricia; Aliaga, Álvaro; Lillo, Patricia; Delgado, Carolina; Tenorio, Marcela; Rosas, Ricardo; López, Oscar; Becker, James; Slachevsky Chonchol, Andrea
The Frontal Assessment Battery (FAB) is a screening test that measures executive functions. Although this instrument has been validated in several countries, its diagnostic utility in a Chilean population has not been studied yet. Objectives: This study aimed to (1) adapt FAB in a Chilean population; (2) study the psychometric properties of the FAB in a Chilean population; (3) assess the sociodemographic influence in the performance of the FAB in a sample of healthy controls (HC); and (4) develop normative data for this healthy group. Methods: A HC (n=344) and a group of patients with dementia (n=156) were assessed with the Chilean version of FAB. Results: FAB showed good internal consistency (Cronbach's alpha=0.79) and acceptable validity based on the relationship with other variables. Factor analysis showed the unidimensionality of the instrument. Significant differences were found in the total FAB value between the HC and dementia groups. With the matched sample, the established cutoff point was 13.5, showing a sensitivity of 80.8% and a specificity of 90.4%. Regression analysis showed that education and age significantly predicted FAB performance in the healthy group. Finally, normative data are provided. Conclusions: This study shows that FAB is a useful tool to discriminate between healthy people and people with dementia. However, further studies are needed to explore the capacity of the instrument to characterize the dysexecutive syndrome in people with dementia in the Chilean population.
Traditional Assessment or Invisible Assessment Using Games? New Frontiers in Cognitive Assessment.
(2015) Rosas, Ricardo; Ceric, Francisco; Aparicio, Andrés; Arango, Paulina; Arroyo, Rodrigo; Benavente, Catalina; Escobar, Pablo; Olguín, Polín; Pizarro, Marcelo; Ramírez, María Paz; Tenorio, Marcela
This paper addresses the problem of anxiety related to traditional assessment, which can affect assessment outcomes and underestimate the performance of subjects. Invisible assessment makes it possible to evaluate subjects without making them feel like they are being evaluated. Invisible evaluation tests were developed for touch screen tablets for 3 cognitive domains: intelligence, calculation, and reading. These tests were applied to 337 children from kindergarten through third grade, who attended 3 mixed-funding schools in Santiago, Chile. The schools were convenience sampled and all the children whose parents signed the informed consent form were included. The final sample was randomly distributed among the domains. Correlations between traditional assessment tests and invisible assessment tests were observed. Children reported a preference for invisible assessment over traditional assessment. Subjects with low academic performance obtained better scores on invisible assessment tests than on traditional tests, according to a mixed factors analysis of variance. These findings suggest that it is possible to assess cognitive domains with nontraditional instruments and that they can reveal the real academic performance of subjects.
Your baby has down syndrome: a reflexive thematic analysis of breaking the news to parents
(2025) Tenorio, Marcela; Sagner-Tapia, Johanna; Garibaldi, Renata; Totsika, Vaso
The communication of a Down syndrome diagnosis to mothers is a pivotal moment that can impact their emotional well-being and the subsequent care for their child. This study aimed to explore maternal experiences with receiving a Down syndrome diagnosis. A total of 40 mothers participated, 42.5% received a prenatal diagnosis, 17.5% received the diagnosis during labor and delivery, and 40% received the information at the early postnatal period. Through reflexive thematic analysis, four key themes emerged: (1) About Who and How the News Was Delivered (2), About When the News Was Delivered (3), On Where the News Should Be Delivered (4), parents’ positive experiences emerging from this, predominantly, negative episode. Our findings emphasize the need for improved training for healthcare professionals in delivering sensitive diagnoses, with an emphasis on empathy, accurate information, and support resources for families.
