RESUMO

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 efficiently 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. Hierarchical 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. WHAT THIS PAPER ADDS: What is already known on the subject VFT are widely used within the paediatric population due to its sensitivity to brain injury. Its score is based on the number of correct words produced; however, TS alone gives little information regarding underlying test performance. Several normative data for VFT TS in the paediatric population exist, but normative data for clustering and switching strategies are scarce. What this paper adds to existing knowledge The present study is the first to describe the Colombian adaptation of the scoring guidelines for clustering and switching strategies, and provided normative data for these strategies for children and adolescents between 6 and 17 years old. What are the potential or actual clinical implications of this work? Knowing VFT's performance, including strategy development and use in healthy children and adolescents, may be useful for clinical settings. We encourage clinicians to include not only TS, but also a careful analysis of strategies that may be more informative of the underlying cognitive processes failure than TS.

RESUMO

AIM: Neuropsychological normative data for Latin America have been recently published, and for Colombia, in particular, but longitudinal neuropsychological outcomes after stroke have not yet been examined in this global region. The purpose of the current study was to compare functioning of individuals with stroke in Colombia, South America during the first year post-stroke to healthy controls across neuropsychological assessments of memory, language, and visuoperceptual impairments. METHOD: A sample of 50 individuals with stroke (mean age = 51.58) and 50 matched healthy controls (mean age = 51.54) from Colombia were included in this study. Because of a lack of access to health services, individuals with stroke did not receive any inpatient or outpatient cognitive or behavioral rehabilitation. Participants were assessed on 10 visuoperceptual, language, and memory tasks at 3, 6, and 12 months. RESULTS: Trajectories of neuropsychological performance were significantly worse among individuals with stroke than healthy controls across every index. Further, hierarchical linear models suggested that although both individuals with stroke and controls generally improved over time on these assessments, the improvements among individuals with stroke were often of no greater magnitude than the improvements seen in controls, suggesting extremely low levels of rehabilitation gains in Colombia. Only three of the 10 neuropsychological assessments did a significant time*group interaction occur, suggesting greater gains for the stroke group than controls. CONCLUSION: These findings suggest profound disparities in post-stroke cognitive functioning in Colombia compared to other more developed global region and underscore the importance of comprehensive cognitive rehabilitation services for individuals with stroke in Colombia and other similar global regions. Implications for rehabilitation Because this study found only negligible cognitive improvements beyond practice effects over the first year after stroke in Colombia among individuals without access to acute rehabilitation, it is imperative that comprehensive cognitive rehabilitation services be implemented immediately during the acute rehabilitation period. Memory, language, and visuoperceptual training strategies can be implemented for people with stroke in underserved global regions as part of the standard of care for stroke rehabilitation. Cognitive rehabilitation strategies should be adapted into Spanish and pilot tested in Latin America to ensure cultural equivalence. Culturally competent cognitive rehabilitation strategies should be tailored based on varied educational and literacy levels.

RESUMO

BACKGROUND: Previous literature has shown disparities between developing and developed regions in executive functioning, attention, and processing speed performance following stroke. Research on post-stroke longitudinal outcomes in Latin America specifically is almost nonexistent. OBJECTIVES: To assess spontaneous recovery among individuals with stroke in the absence of cognitive rehabilitation services in Colombia, South America during the first year post-stroke by comparing their functioning to that of healthy controls across executive functioning, attention, and processing speed at 3, 6, and 12 months. DESIGN: Cohort. SETTING: Stroke rehabilitation center at the regional hospital. PARTICIPANTS: A sample of 50 individuals with stroke and 50 matched healthy controls from Colombia were included in this study. Consistent with the healthcare resources in this region, participants did not receive any inpatient or outpatient cognitive rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Executive functioning, attention, and processing speed. RESULTS: Hierarchical linear models suggested improvements over time for both individuals with stroke and controls, but trajectories of neuropsychological performance were significantly lower for individuals with stroke. Only on one of nine outcomes was there a significant time*group interaction, suggesting greater gains for the stroke group than controls. CONCLUSIONS: These data suggest extremely minor spontaneous recovery among individuals with stroke in Colombia relative to practice effects in controls, and that apparent improvements in executive functioning after stroke were likely just due to practice effects. These findings underscore the bleak outcomes in cognitive functioning after stroke that occur in regions without cognitive rehabilitation.

RESUMO

Pediatric traumatic brain injury (TBI) represents a serious public health concern. Family members are often caregivers for children with TBI, which can result in a significant strain on familial relationships. Research is needed to examine aspects of family functioning in the context of recovery post-TBI, especially in Latin America, where cultural norms may reinforce caregiving by family members, but where resources for these caregivers may be scarce. This study examined caregiver-reported family satisfaction, communication, cohesion, and flexibility at three time points in the year post-injury for 46 families of a child with TBI in comparison to healthy control families. Families experiencing pediatric TBI were recruited from a large hospital in Guadalajara, Mexico, while healthy controls were recruited from a local educational center. Results from multilevel growth curve models demonstrated that caregivers of children with a TBI reported significantly worse family functioning than controls at each assessment. Families experiencing pediatric TBI were unable to attain the level of functioning of controls during the time span studied, suggesting that these families are likely to experience long-term disruptions in family functioning. The current study highlights the need for family-level intervention programs to target functioning for families affected by pediatric TBI who are at risk for difficulties within a rehabilitation context.

RESUMO

PRIMARY OBJECTIVE: The Post-Concussion Syndrome Scale (PCSS) is a self-report questionnaire that measures post-concussive symptom severity and has been primarily normed on young Caucasian samples. This study aims to explore the factor structure models of a Spanish translation of the PCSS at a chronic post-traumatic brain injury (TBI) time point. RESEARCH DESIGN: Descriptive and exploratory research designs were utilized. METHODS AND PROCEDURES: The study consisted of a monolingual sample of Spanish-speaking adults from Colombia, with 100 subjects in the control group and 70 subjects in the TBI group. A t-test, chi-square, and MANOVA were calculated to compare group differences. Cronbach's alpha was calculated to investigate reliability. Confirmatory factor analysis compared item loadings onto an existing four-factor model. Exploratory factor analysis sought to identify a new factor model if the loadings did not fit. MAIN OUTCOMES AND RESULTS: There were no group differences in demographic variables. Internal consistency was acceptable. Model fit indices revealed a poor fit with the original four factors. Item loadings revealed a novel six-structure model. CONCLUSIONS: While the PCSS appears to capture general post-TBI sequelae, the underlying factors may differ due to cultural and linguistic differences in Spanish-speaking individuals. Clinical implications and future directions are further discussed.

RESUMO

OBJECTIVE: To determine the prevalence of low scores for two neuropsychological tests with five total scores that evaluate learning and memory functions. METHOD: N = 5402 healthy adults from 11 countries in Latin America and the commonwealth of Puerto Rico were administered the Rey-Osterrieth Complex Figure (ROCF) and the Hopkins Verbal Learning Test (HVLT-R). Two-thirds of the participants were women, and the average age was 53.5 ± 20.0 years. Z-scores were calculated for ROCF Copy and Memory scores and HVLT-R Total Recall, Delayed Recall, and Recognition scores, adjusting for age, age2, sex, education, and interaction variables if significant for the given country. Each Z-score was converted to a percentile for each of the five subtest scores. Each participant was categorized based on his/her number of low scoring tests in specific percentile cutoff groups (25th, 16th, 10th, 5th, and 2nd). RESULTS: Between 57.3% (El Salvador) and 64.6% (Bolivia) of the sample scored below the 25th percentile on at least one of the five scores. Between 27.1% (El Salvador) and 33.9% (Puerto Rico) scored below the 10th percentile on at least one of the five subtests. Between 5.9% (Chile, El Salvador, Peru) and 10.3% (Argentina) scored below the 2nd percentile on at least one of the five scores. CONCLUSIONS: Results are consistent with other studies that found that low scores are common when multiple neuropsychological outcomes are evaluated in healthy individuals. Clinicians should consider the higher probability of low scores when evaluating learning and memory using various sets of scores to reduce false-positive diagnoses of cognitive deficits.

RESUMO

OBJECTIVE: The Boston Naming Test (BNT) is a widely used measure of confrontation naming ability that has been criticized for its questionable construct validity for non-English speakers. This study investigated item difficulty and construct validity of the Spanish version of the BNT to assess cultural and linguistic impact on performance. METHODS: Subjects were 1298 healthy Spanish speaking adults from Colombia. They were administered the 60- and 15-item Spanish version of the BNT. A Rasch analysis was computed to assess dimensionality, item hierarchy, targeting, reliability, and item fit. RESULTS: Both versions of the BNT satisfied requirements for unidimensionality. Although internal consistency was excellent for the 60-item BNT, order of difficulty did not increase consistently with item number and there were a number of items that did not fit the Rasch model. For the 15-item BNT, a total of 5 items changed position on the item hierarchy with 7 poor fitting items. Internal consistency was acceptable. CONCLUSIONS: Construct validity of the BNT remains a concern when it is administered to non-English speaking populations. Similar to previous findings, the order of item presentation did not correspond with increasing item difficulty, and both versions were inadequate at assessing high naming ability.

RESUMO

BACKGROUND: Stroke is a primary cause of death and disability in upper-middle-income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region. OBJECTIVE: To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia. DESIGN: Cross-sectional study. SETTING: The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia. PARTICIPANTS: Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50). METHODS: Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnaires MAIN OUTCOME MEASUREMENTS: Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke. RESULTS: Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls. CONCLUSIONS: This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues. LEVEL OF EVIDENCE: I.

RESUMO

El objetivo de este estudio fue conocer las características de la práctica neuropsicológica en México, incluyendo la formación profesional, la situación laboral actual, el proceso de evaluación y diagnóstico, rehabilitación, docencia e investigación. Participaron 171 profesionales en México, quienes respondieron una encuesta electrónica entre el 1 de julio del 2013 y el 1 de enero del 2014. El 76% indicó haber obtenido su entrenamiento en neuropsicología durante el postgrado y, aunque indicaron estar muy satisfechos con su labor, su satisfacción con el salario fue menor. La mayoría trabajan con personas con problemas de aprendizaje (78%) y trastornos de atención e hiperactividad (74%). El 91% se dedica a evaluación y diagnóstico, 61% a rehabilitación, 67% a docencia y 60% a investigación. Los problemas más comunes fueron la falta de datos normativos (63%) y el alto coste de los test (58%). Las barreras más observadas en el desarrollo de la neuropsicología fueron la falta de colaboración entre los profesionales y la falta de programas de formación clínica. Durante las últimas décadas se han logrado importantes avances a nivel profesional en el campo de la neuropsicología en México. Sin embargo, aún quedan aspectos por mejorar como el establecimiento de criterios para la regulación de la práctica neuropsicológica en el país.

The objective of this study was to analyze the characteristics of the profession of neuropsychology in Mexico, including the background, professional training, current work situation, evaluation and diagnosis procedures, rehabilitation, teaching, and research. 171 professionals from Mexico completed an online survey between July 1, 2013 and January 1 of 2014. 76% indicated having obtained their training in neuropsychology in a postgraduate program, also to be very satisfied with their jobs, but less satisfied with their salary. The majority works with individuals with learning difficulties (78%) and attention and hyperactivity disorder (74%). 91% works in evaluation and diagnosis, 61% in rehabilitation, 67% in teaching, and 60% in research. Some of the most common problems with the instruments were the lack of normative data (63%) and their high cost (58%). The most common barriers for the development of neuropsychology in Mexico were the lack of collaboration between professionals and the lack of clinical training programs. Even though there have been important progresses in the field of professional neuropsychological practice during the last past decades in Mexico, there are still some aspects to improve, like the establishment of standards for the regulation in the country.

RESUMO

BACKGROUND: Despite the body of research on caregivers of individuals with various types of disabilities, SCI caregivers have received comparably less attention, especially in regions like Latin America. OBJECTIVE: The purpose of this study was to examine the association between HRQOL and mental health in SCI caregivers from Colombia. METHOD: A cross sectional study assessed SCI caregivers (n = 40) in Neiva, Colombia. Participants completed a measure of their HRQOL (SF-36 Health Questionnaire) and four measures of mental health (Satisfaction With Life Scale, Zarit Burden Interview, Patient Health Questionnaire-9, and State-Trait Anxiety Inventory). RESULTS: A canonical correlation between variables revealed that 64% of the variance was shared between mental health and HRQOL. The domains that loaded highest within the canonical correlation were social functioning, general health, and anxiety, indicating that SCI caregivers with higher anxiety experienced lower social functioning and lower general health. Furthermore, 15 of the 24 bivariate correlations between mental health and HRQOL were statistically significant, suggesting a strong connection between these two sets of variables. CONCLUSION: Rehabilitation professionals in Latin America should consider the development of caregiver interventions focusing on both physical and mental health, as the two constructs are closely connected through social functioning, general health, and anxiety.
