Publication Open Access Network analysis of neurobehavioral symptom patterns in an international sample of spanish-speakers with a history of COVID-19 and controls(MDPI, 2023) Perrin, Paul B.; Ramos Usuga, Daniela; West, Samuel J.; Merced, Kritzia; Klyce, Daniel W.; Lequerica, Anthony H.; Olabarrieta Landa, Laiene; Alzueta, Elisabet; Baker, Fiona C.; Iacovides, Stella; Cortes, Mar; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaBackground: Psychometric network analysis provides a novel statistical approach allowing researchers to model clusters of related symptoms as a dynamic system. This study applied network analysis to investigate the patterns of somatic, cognitive, and affective neurobehavioral symptoms in an international sample of Spanish-speaking individuals with a history of COVID-19 positivity and non-COVID controls; (2) methods: the sample (n = 1093) included 650 adults from 26 countries who reported having previously tested positive for COVID-19 (COVID+) through a viral and/or antigen test (average of 147 days since diagnosis). The control group (COVID−) was comprised of 443 adults from 20 countries who had completed the survey prior to the COVID19 pandemic; (3) results: relative to the COVID− network, the COVID+ network was very wellconnected, such that each neurobehavioral symptom was positively connected to the network. The organize-to-headache and dizzy-to-balance connections in the COVID+ network were stronger than in the COVID− network. The hearing, numbness, and tense symptoms were more central to the COVID+ network with the latter connected to the sleep, fatigue, and frustrated symptoms. The COVID− network was largely disjointed, with most of the somatosensory symptoms forming their own cluster with no connections to other symptom groups and fatigue not being connected to any other symptom. The cognitive and affective symptoms in the COVID− network were also largely connected to symptoms from within their own groups; (4) conclusions: These findings suggest that many of the long-term neurobehavioral symptoms of COVID-19 form a discernable network and that headaches, frustration, hearing problems, forgetfulness, and tension are the most central symptoms. Cognitive and behavioral rehabilitation strategies targeting these central symptom network features may hold promise to help fracture the lingering symptom network of COVID-19.Publication Open Access 15-item version of the Boston naming test: normative data for the Latin American spanish-speaking adult population.(American Psychological Association, 2023) Del Cacho Tena, Ana María; Merced, Kritzia; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Olabarrieta Landa, Laiene; Rivera, Diego; Ciencias de la Salud; Osasun ZientziakObjective: Naming is commonly impaired in people with neurodegenerative diseases and brain injury, and as a result, its accurate assessment is essential. The aim of this study was to provide normative data for the 15-item Spanish version of the Boston Naming Test (BNT) for an adult population from eight Latin American countries/regions. Method: The total sample consisted of 2,828 participants from Argentina, Chile, Cuba, El Salvador, Mexico, Honduras, Paraguay, and Puerto Rico. Multiple regressions were used to generate normative data following a four-step process. Results: Regression models showed a linear effect of age on the 15-item BNT total score for Argentina, Chile, Mexico, and Puerto Rico. In contrast, Paraguay showed a quadratic age effect. Almost all countries showed a positive linear effect of education, except Cuba which had a quadratic effect. Sex was a significant predictor in Argentina, Chile, Cuba, and Mexico, where in women scored lower than men. Conclusions: This study generates normative data for the 15-item Spanish version of the BNT and offers a free open-source calculator that will assist in the efficacious use of this neuropsychological test in clinical practice and research.
