This study evaluated the universality of the TOMM 2 and provided a reference sample of cognitively intact adults living in Spain whose native language was Spanish. A total of 203 adults completed the TOMM 2 from June 2019 to January 2020. When using the original TOMM cutoff scores derived from English speakers, all participants scored in a range that would suggest that they passed the TOMM. When using a cut score less than 40 on Trial 1, only one participant in this study would be mistakenly classified as providing an invalid performance. Spanish-speaking adults in Spain from this study achieved a perfect score on Trial 1 at a rate more than double that of English-speaking individuals on the original TOMM. At the item level, all but one item met the minimum standard for performance validity; this item fell only marginally below the standard at 89%. This study found a very low failure rate for the TOMM 2, suggesting that the second edition has at least as high specificity as the original in Spanish adults.

(SAGE, 2024-09-20) Rivera, Diego; Forte, Anabel; Olabarrieta Landa, Laiene; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
Objective: To present the methodology for a study generating normative neuropsychological test data for healthy Spanish-speaking adults (18-80 years old) living in the U.S. using Bayesian inference as a novel approach. Method: The study sample consisted of 253 healthy adults from eight U.S. regions (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin), with individuals originating from a diverse array of Latin American countries. To participate in the study, individuals must have met the following criteria: were between 18 and 80 years of age, had lived in the U.S. for at least 1 year (12 continuous months), self-identified Spanish as their dominant language, had at least one year of formal education, were able to read and write in Spanish at the time of evaluation, scored ¿23 on the Mini-Mental State Examination, scored <10 on the Patient Health Questionnaire¿9, and scored <10 on the Generalized Anxiety Disorder scale. Participants completed 12 neuropsychological tests. Reliability statistics and norms were calculated for all tests. Conclusions: This was the first normative study for Spanish-speaking adults in the U.S. to implement demographic, acculturation, and bilingual dominance measures as possible controls. Additionally, it was the first study to use Bayesian linear or generalized linear regression models for generating normative data in neuropsychology.

Normative data for tests of visuo-spatial, visuo-constructional skills, and visual memory for Spanish-speaking adults in the United States
(SAGE, 2024-09-17) Morel Valdés, Gloria M.; Rivera, Diego; Olabarrieta Landa, Laiene; Carrión, Carmen I.; Lequerica, Anthony H.; Maltez, Fatima Iyarit; Rodríguez, Miriam J.; Dini, Mia E.; Munoz, Geovani; Ramos Usuga, Daniela; Drago, Christin I.; García, Patricia; Rivera, Patricia M.; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
Background: The Rey-Osterrieth Complex Figure Test (ROCFT) and the Clock Drawing Test (CDT) are commonly used in clinical practice. The ROCFT measures constructional praxis, visual perception, and visuospatial learning and memory and the CDT assesses for visuospatial, constructional, and executive difficulties. Several neurological disorders are associated with visuospatial and visuoconstructional impairments, yet reliable normative data accounting for sociodemographic aspects of identity and acculturative variables are scarce for Hispanics living in the U.S. Objective: To generate normative data for the ROCF and CDT in a Spanish-speaking adult population living in the U.S. Methods: The sample consisted of 245 participants' cognitively normal adults, recruited from several states in the U.S. Each participant was administered the ROCFT and CDT as part of a larger cognitive battery. The ROCFT and CDT were normed using a Bayesian approach. Age, age, education, sex, acculturation, and language competence, were included as predictors in the analyses. Results: ROCFT was associated with education and age, particularly as they interact with Spanish language competency, and time spent in the U.S. Education was significantly associated with recall abilities and a lower memory recall on the ROCFT. Age was found to vary depending on a person¿s bilingual abilities. Sex did not emerge as a predictor of performance, and it was not moderated by other variables. Conclusions: This is the first study to include acculturation and language proficiency variables in the creation of norms for the assessment of visuoconstruction abilities. This study will have a large impact on the practice of neuropsychology in the U.S.

Phonological and semantic verbal fluency test: Scoring criteria and normative data for clustering and switching strategies for Colombian children and adolescents
(Wiley, 2023) Álvarez Medina, María Nazareth; Vergara Moragues, Esperanza; Arango Lasprilla, Juan Carlos; Restrepo Moreno, Juan Carlos; Calderón Chagualá, José Amilkar; Rivera, Diego; Olabarrieta Landa, Laiene; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Background: Verbal fluency tests (VFT) are highly sensitive to cognitive deficits. Usually, the score on VFT is based on the number of correct words produced, yet it alone gives little information regarding underlying test performance. The implementation of different strategies (cluster and switching) to perform effi-ciently during the tasks provide more valuable information. However, normative data for clustering and switching strategies are scarce. Moreover, scoring criteria adapted to Colombian Spanish are missing. Aims: (1) To describe the Colombian adaptation of the scoring system guidelines for clustering and switching strategies in VFT; (2) to determine its reliability; and (3) to provide normative data for Colombian children and adolescents aged 6–17 years. Methods & Procedures: A total of 691 children and adolescents from Colombia completed phonological (/f/, /a/, /s/, /m/, /r/ and /p/) and semantic (animals and fruits) VFT, and five scores were calculated: total score (TS), number of clusters (NC), cluster size (CS), mean cluster size (MCS) and number of switches (NS). The intraclass correlation coefficient was used for interrater reliability. Hierarhical multiple regressions were conducted to investigate which strategies were associated with VFT TS. Multiple regressions were conducted for each strategy, including as predictors age, age2, sex, mean parents’ education (MPE), MPE2 and type of school, to generate normative data. Outcomes & Results: Reliability indexes were excellent. Age was associated with VFT TS, but weakly compared with strategies. For both VFT TS, NS was the strongest variable, followed by CS and NC. Regarding norms, age was the strongest predictor for all measures, while age2 was relevant for NC (/f/phoneme) and NS (/m/ phoneme). Participants with higher MPE obtained more NC, and NS, and larger CS in several phonemes and categories. Children and adolescents from private school generated more NC, NS and larger CS in /s/phoneme. Conclusions & Implications: This study provides new scoring guidelines and normative data for clustering and switching strategies for Colombian children and adolescents between 6 and 17 years old. Clinical neuropsychologists should include these measures as part of their everyday practice.

Spain, the land of diversity
(Routledge, 2022) Olabarrieta Landa, Laiene; Goméz López, María Jesús; González Wongvalle, Isabel; Rivera, Diego; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
The aim of this chapter is to present relevant cultural aspects that a neuropsychologist should take into account in order to provide adequate service to Spanish patients and their families. In the first section, there is an introduction to the Spanish culture, which is linked to small case studies that reflect its relevance from a neuropsychological point of view. Spain is culturally complex, with different regions that maintain their own traditions and languages. For Spaniards, social relationships and family are so important that patients may prioritize some rehabilitation goals against others in order to recover their social functioning. Likewise, the complex relationship between languages and education is presented, as well as the educational and socioeconomic level of the country. In the second section, the importance of social relationships and the role of the family in the neuropsychological assessment and rehabilitation, as well as the context in which the patient lives, are explored closely through RJ case. Finally, the chapter ends with a summary of the most relevant ideas to consider when assessing a Spanish patient.

Multivariate base rates of low scores on tests of executive functions in a multi-country Latin American sample
(Routledge, 2021) Rivera, Diego; Mascialino, Guido; Brooks, Brian L.; Olabarrieta Landa, Laiene; Longoni, Melina; Galarza-Del-Ángel, Javier; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
The objective of the study was to determine the prevalence of low scores in a diverse Latin American population for two neuropsychological commonly used tests to evaluate executive functions and to compare the number of low scores obtained using normative data from a Spanish-speaking population from Latin America versus an English-speaking population from U.S.A. Healthy adults (N = 5402) were administered the Modiﬁed Wisconsin Card Sorting Test and Stroop Color-Word. Low scores on measures of executive functioning are common. Clinicians working with Spanish-speaking adults should take into account the higher probability of low scores on these measures to reduce false-positive diagnoses of cognitive deficits in an individual.

Comparability of (post-concussion) symptoms across time in individuals after traumatic brain injury: results from the CENTER-TBI study
(MDPI, 2022) Rivera, Diego; Greving, Sven; Arango Lasprilla, Juan Carlos; Steinbuechel, Nicole von; Zeldovich, Marina; Ciencias de la Salud; Osasun Zientziak
Post-concussion symptoms often occur after TBI, persist and cause disabilities. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) is widely used in this population, but little is known about the comparability of the symptoms over time, i.e., longitudinal measurement invariance (MI). The objectives of this study were to analyze the longitudinal MI of RPQ symptoms from three to twelve months after TBI and to find factors related to RPQ symptoms. The study involved 1023 individuals after TBI who took part in the Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) study and completed the RPQ at three, six and twelve months postinjury. Longitudinal confirmatory factor analysis showed that the three-factor structure (somatic, emotional and cognitive) remains stable within one year after TBI. Linear mixed models revealed that sex, injury cause and prior psychiatric problems were related to the RPQ three-factor structure as well as to the RPQ total score. The study strengthens evidence for the RPQ’s factorial structure stability within one year after TBI and identifies sex, injury cause and prior psychiatric problems as important factors that may help clinicians to prevent future complications of symptomatology after TBI.

(Elsevier, 2022) Rivera, Diego; Ramos Usuga, Daniela; Fuentes Mendoza, Eliana María; Aguayo Arelis, Adriana; Rabago Barajas, Brenda Viridiana; Macías Islas, Miguel Ángel; Krch, Denise; Lequerica, Anthony H.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
Background. Between 50-60% of Multiple Sclerosis (MS) patients have cognitive alterations. There are several batteries to assess cognitive impairments in MS, however, few exist for Latin Americans. The objective of this study is to evaluate the neuropsychological profile of Mexican people with MS (PwMS) and assess the utility of Norma Latina, a new battery for cognitive assessment in Latin America, in differentiating cognitive test performance between PwMS and healthy controls (HC). Methods. 100 PwMS and 100 HC from Mexico were evaluated with the Norma Latina battery. The following analyses were conducted: 1) low-percentiles of each participant were calculated, 2) Area Under the Curve was used to determine whether the battery discriminated between PwMS and HC, 3) four composite scores were calculated, and student’s t-test was used to compare groups according to these domains. Results. PwMS obtained a greater number of impaired scores compared to HCs, principally in executive function. The battery successfully discriminated between PwMS and HCs, with the strongest capacity to discriminate in the executive functions, and the weakest in memory. Conclusion. Establishing validation of a neuropsychological battery for Mexican PwMS will help to more accurately detect cognitive alterations, which will guide the decisions of professionals in terms of cognitive rehabilitation.

Multivariate base rates of low score on neuropsychological tests of individuals with coca paste use disorder
(Oxford University Press, 2023) Vergara Moragues, Esperanza; Acosta Barreto, María Rocío; Rivera, Diego; Santiago Ramajo, Sandra; González-Saiz, Francisco; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
OBJECTIVE: The aim of this study was to determine the prevalence of low scores on eight commonly used neuropsychological tests to evaluate learning and memory, language, and executive functions in individuals with coca paste use disorders (CPUD) and to identify the differences with respect to a group of healthy nonconsuming subjects (HCs). METHODS: 162 Colombian adults with CPUD and a group of 162 Colombian adult HCs participated in this comparative study. Eight tests (eighteen test scores) were grouped into three categories: learning and memory, language, and executive functions. Each participant was categorized based on the number of low scoring tests in specific percentile cut-off groups (25th, 16th, 10th, 5th, and 2nd). RESULTS: In the learning and memory domain, 89.5% of individuals with CPUD and 55.6% of HCs scored below the 25th percentile on at least one of the five test scores, in the language domain, 80.7% of individuals with CPUD and 58% of HCs and in the executive function domain, 92% of individuals with CPUD and 67.3% of HCs. Having two or more scores below the 10th percentile or 10 or more at the 5th percentile shows an optimal cut-off for determining the sensitivity and specificity for discriminating between the two groups. CONCLUSIONS: The individuals with CPUD had a higher percentage of low scores than the HCs in the domains of learning and memory, language, and executive function. It is important for clinicians to be aware of low scores in individuals with CPUD to avoid false-positive diagnoses of cognitive impairment.

A preliminary examination of the TOMM2 in a sample of Spanish speakers in the United States
(SAGE, 2024-09-02) Ramos Usuga, Daniela; Ayearst, Lindsay E.; Rivera, Diego; Krch, Denise; Perrin, Paul B.; Carrión, Carmen I.; Morel Valdés, Gloria M.; Loro, Delly; Rodríguez, Miriam J.; Munoz, Geovani; Drago, Christin I.; García, Patricia; Rivera, Patricia M.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
BACKGROUND: The Test of Memory Malingering (TOMM) is a widely used performance validity measure that is available in both English and Spanish. The Spanish version, however, has historically lacked normative data from samples that are representative of the U.S. Hispanic/Spanish speaking population. OBJECTIVE: The aim of the current study was to collect normative data on the update TOMM 2 for Hispanic individuals residing in the U.S. METHODS: Normative data on the TOMM 2 was collected across 9 sites from different regions of the U.S. The total sample consisted of n=188 cognitively healthy adults aged 18 and over with no current or prior history of neurological or psychiatric disorder. Descriptive analyses were performed on total raw scores. RESULTS: Participants obtained a mean score of 48.15 (SD=2.81) on trial 1 of the TOMM 2, 49.86 (SD=0.487) on trial 2, and 49.84 (SD=0.509) on the recognition trial. Scores are provided for traditional cutoff scores as well as some popular cutoffs reported in the literature. Item level analyses were conducted as well as evaluation of performance based on a variety of demographics. CONCLUSION: When compared to the English-speaking normative sample used for the original TOMM, this sample demonstrated better performance on the TOMM 2 indicating better cultural appropriateness of the items. This is the first study conducted that provides culturally appropriate descriptive norms for use with Spanish speakers living in the U.S.
