Normative data for the Spanish versions of the CVLT, WMS-Logical Memory, and RBMT from a sample of middle-aged and old participants.

Episodic memory (EM), one of the most commonly assessed cognitive domains in aging, is useful for identifying pathological processes such as mild cognitive impairment and dementia. However, EM tests must be culturally adapted, and the influence of sociodemographic variables analyzed, to provide cut-off points that enable correct diagnosis. The aim of this article is to report updated Spanish normative data for three EM tests: the California Verbal Learning Test, the Logical Memory subtest of the Wechsler Memory Test, and the Rivermead Behavioral Memory Test. Measures include immediate, short-, and long-delay free recall, intrusions, and global scores. The entire sample is comprised of 1,193 cognitively unimpaired participants aged +50, recruited from three cohort studies within the Spanish Consortium for Ageing Normative Data. Participants who subsequently developed cognitive impairment, detected at follow-up, were removed from the total sample. Data analysis included transformation of percentile ranges into scalar scores, tests for the effects of education level, age, and sex on performance, and linear regression to calculate scalar adjustments. Tables with percentile ranges and scalar scores for each measure are provided, with adjustments for age, education level, and sex, as required. The normative scores provide robust data for assessing EM in Spanish middle-aged and old populations. Effects of sex, age, and education level in each measure are discussed.

Social Loneliness in Older Adults with Mild Cognitive Impairment: Predictive Factors and Associated Clinical Characteristics.

BACKGROUND: Loneliness and social isolation are considered public health problems among older individuals. In addition, both increase the risk of developing cognitive impairment and dementia. The Social Loneliness construct has been proposed to refer to these harmful social interaction-related factors. OBJECTIVE: To define the risk factors of Social Loneliness in individuals with mild cognitive impairment (MCI) and to analyze cognitive, emotional, and functional differences according to the participant's degree of Social Loneliness. METHODS: Through convenience sampling, 105 participants over 60 diagnosed with MCI were selected. The evaluation consisted of anamnesis and a comprehensive neuropsychological examination. The ESTE-II questionnaire was used to assess Social Loneliness and its three factors: perceived social support, social participation, and use of communication technologies. Personality was measured with the NEO-FFI questionnaire. RESULTS: The predictors of the Social Loneliness factors were as follows; 1) perceived social support (R2 = 0.33): Neuroticism (ß= 0.353), depression (ß= 0.205), and perceived health (ß= 0.133); 2) social participation (R2 = 0.24): Conscientiousness (ß= -0.344) and Extraversion (ß= -0.263); 3) use of communication technologies (R2 = 0.44): age (ß= 0.409), type of cohabitation (ß= 0.331), cognitive reserve (ß= -0.303), and Conscientiousness (ß= -0.247); all p < 0.05. The participants with a higher degree of Social Loneliness showed more depressive symptoms (R2 = 0.133), more memory complaints (R2 = 0.086), worse perceived health (R2 = 0.147), lower attentional performance/processing speed (R2 = 0.094), and more naming difficulties (R2 = 0.132); all p < 0.05. CONCLUSIONS: This research represents an advance in detecting individuals with MCI and an increased risk of developing Social Loneliness, which influences the configuration of the clinical profile of MCI.

Sex differences in the progression to Alzheimer's disease: a combination of functional and structural markers.

Mild cognitive impairment (MCI) has been frequently interpreted as a transitional phase between healthy cognitive aging and dementia, particularly of the Alzheimer's disease (AD) type. Of note, few studies explored that transition from a multifactorial perspective, taking into consideration the effect of basic factors such as biological sex. In the present study 96 subjects with MCI (37 males and 59 females) were followed-up and divided into two subgroups according to their clinical outcome: "progressive" MCI (pMCI = 41), if they fulfilled the diagnostic criteria for AD at the end of follow-up; and "stable" MCI (sMCI = 55), if they remained with the initial diagnosis. Different markers were combined to characterize sex differences between groups, including magnetoencephalography recordings, cognitive performance, and brain volumes derived from magnetic resonance imaging. Results indicated that the pMCI group exhibited higher low-frequency activity, lower scores in neuropsychological tests and reduced brain volumes than the sMCI group, being these measures significantly correlated. When sex was considered, results revealed that this pattern was mainly due to the influence of the females' sample. Overall, females exhibited lower cognitive scores and reduced brain volumes. More interestingly, females in the pMCI group showed an increased theta activity that correlated with a more abrupt reduction of cognitive and volumetric scores as compared with females in the sMCI group and with males in the pMCI group. These findings suggest that females' brains might be more vulnerable to the effects of AD pathology, since regardless of age, they showed signs of more pronounced deterioration than males.

Genetic Predictors of Change in Episodic Verbal Memory by Cognitive Intervention: ACT, PICALM, BDNF, NRG1, APOE Genes and Their Interactions in Situations of Cognitive Demand.

BACKGROUND: Cognitive interventions (CIs) in the elderly are activities that seek to improve cognitive performance and delay its deterioration. Our objectives were to study potential genetic predictors of how a CI program may influence immediate and delayed episodic verbal memory (EVM). METHODS: 162 participants were elderly individuals without dementia who were randomized into parallel control and experimental groups. Participants underwent genetic testing to analyze the PICALM, ACT, NRG1, BDNF and APOE genes. We performed a broad neuropsychological assessment before and 6 months after the CI. The CI involved multifactorial training (30 sessions). The control group undertook the centre's standard activities. The main outcome measures were the genotype studied as a predictor of post-intervention changes in EVM. RESULTS: We found the CI was associated with improvements in several cognitive functions, including immediate and delayed EVM. While no individual gene was associated with any such change, the interaction between PICALM/ACT (p = 0.008; Eta2 = 0.23) and PICALM/NRG1 (p = 0.029; Eta2 = 0.19) was associated with improved immediate EVM, and the NRG1/BDNF interaction was associated with improved delayed EVM (p = 0.009; Eta2 = 0.21). The APOEε4 genotype was not associated with any change in EVM. CONCLUSIONS: Our study shows that the participants' genotype can have an impact on the results of CIs. Cognitive stress may stimulate the interaction of various genes and as such, different types of CI should be established for distinct groups of people taking into account the individual's characteristics, like genotype, to improve the results of this type of health prevention and promotion activity.

Loneliness in the elderly: association with health variables, pain, and cognitive performance. A population-based study / La soledad en personas mayores: asociación con las variables de salud, el dolor y el rendimiento cognitivo. Estudio poblacional

The aim of this population-based study is to analyze the association of loneliness and physical health, pain, health-related quality of life, mental health, cognitive performance, morbidity, and use of health services. Based on the census, a stratified random sampling was chosen. A telephone interview was conducted with 2,060 people over 65 years old, using the GHQ-12 and the COOP-Wonca. An association of loneliness with General Mental Health (GHQ-12) was found, OR = 1.43 (1.34, 1.52) and depression, OR = 2.34 (1.54, 3.53). In cognitive performance the highest effect variable was “memory problems disturb your daily life”, OR = 3.11 (1.25, 7.72); illnesses-related variables: the highest effect variables were perception of health status, OR = 1.37 (1.13, 1. 67) and quality of life (COOP-Wonca), OR = 3.03 (2.32, 3.94); pain-related variables: the highest effect variables were non-localized pain, OR = 2.67 (1.87, 3.83) and arthritis/arthrosis, OR = 1.94 (1.38, 2.72); impaired vision, OR = 2. 62 (1.84, 3.73) and hearing, OR = 1.81 (1.21, 2.72). It is concluded that loneliness is a complex phenomenon associated with variables of different nature. This fact should be taken into account at the time of planning possible solutions. (AU)

El objetivo de este estudio poblacional es analizar la asociación de la soledad no deseada (SND) con salud física, dolor, calidad de vida relacionada con la salud, salud mental, rendimiento cognitivo, morbilidad y uso de servicios de salud. Recurriendo al censo, se realizó un muestreo aleatorio estratificado en Madrid. Se llevó a cabo una entrevista telefónica a 2,060 mayores de 65 años utilizando el GHQ-12 y el COOP-Wonca. Encontramos asociación de la SND y la salud mental general (GHQ-12), OR = 1.43 (1.34, 1.52) y depresión, OR = 2.34 (1.54, 3.53). En rendimiento cognitivo, la variable de mayor efecto fue “los problemas de memoria alteran su vida cotidiana”, OR = 3.11 (1.25, 7.72); variables relacionadas con enfermedad: las de mayor efecto fueron “percepción del estado de salud”, OR = 1.37 (1.13, 1.67) y calidad de vida (COOP-Wonca), OR = 3.03 (2.32, 3.94); variables de dolor: dolor general, OR = 2.67 (1.87, 3.83) y artritis/artrosis, OR = 1.94 (1.38, 2.72); dificultades para ver, OR = 2.62 (1.84, 3.73) y oír, OR = 1.81 (1.21, 2.72). Se concluye que la SND es una situación compleja, lo que debe considerarse al programar soluciones que sean efectivas. (AU)

Cognitive Training Modulates Brain Hypersynchrony in a Population at Risk for Alzheimer's Disease.

BACKGROUND: Recent studies demonstrated that brain hypersynchrony is an early sign of dysfunction in Alzheimer's disease (AD) that can represent a proxy for clinical progression. Conversely, non-pharmacological interventions, such as cognitive training (COGTR), are associated with cognitive gains that may be underpinned by a neuroprotective effect on brain synchrony. OBJECTIVE: To study the potential of COGTR to modulate brain synchrony and to eventually revert the hypersynchrony phenomenon that characterizes preclinical AD. METHODS: The effect of COGTR was examined in a sample of healthy controls (HC, n = 41, 22 trained) and individuals with subjective cognitive decline (SCD, n = 49, 24 trained). Magnetoencephalographic activity and neuropsychological scores were acquired before and after a ten-week COGTR intervention aimed at improving cognitive function and daily living performance. Functional connectivity (FC) was analyzed using the phase-locking value. A mixed-effects ANOVA model with factors time (pre-intervention/post-intervention), training (trained/non-trained), and diagnosis (HC/SCD) was used to investigate significant changes in FC. RESULTS: We found an average increase in alpha-band FC over time, but the effect was different in each group (trained and non-trained). In the trained group (HC and SCD), we report a reduction in the increase in FC within temporo-parietal and temporo-occipital connections. In the trained SCD group, this reduction was stronger and showed a tentative correlation with improved performance in different cognitive tests. CONCLUSION: COGTR interventions could mitigate aberrant increases in FC in preclinical AD, promoting brain synchrony normalization in groups at a higher risk of developing dementia.

Spanish Consortium for Ageing Normative Data (SCAND): Semantic Verbal Fluency Tests.

OBJECTIVE: Semantic verbal fluency constitutes a good candidate for identifying cognitive impairment. This paper offers normative data of different semantic verbal fluency tests for middle-aged and older adults natives from Spain considering sociodemographic factors, and different measures for each specific category (number of words produced, errors, and words evoked every 15 s). METHOD: Two thousand and eighty-eight cognitively unimpaired subjects aged between 50 and 89 years old, community dwelling, participated in the study. The statistical procedure includes the conversion of percentile ranges into scalar scores. Secondly, the effects of age, education and gender were verified. Linear regressions are used to calculate the scalar adjusted scores. RESULTS: Scalar scores and percentiles corresponding to all semantic verbal fluency tests across different measures are shown. Additional tables, which show the points that must be added or subtracted from direct scores, are provided for Education regarding the total number of "animals" and "clothes" evoked by participants, as well as for Age and Education in case of the total number of "clothes". Gender affects the number of "clothes" produced by participants in the first two 15-second segments. CONCLUSIONS: The current norms should provide clinically useful data for evaluating Spanish-speaking natives from Spain aged from 50 to 89 years.

Quejas de memoria: salud mental, enfermedades, dolor y soledad. Estudio poblacional en la ciudad de Madrid / Memory complaints: mental health, diseases, pain and loneliness. A population study in the city of Madrid

Introducción: Las quejas subjetivas de memoria (QSM) se consideran predictoras del deterioro cognitivo, pero se asocian también a otros factores; los sociales y los hábitos de vida han sido los menos estudiados. Objetivo: Valorar las QSM y su asociación con variables epidemiológicas, de salud, sociales y hábitos de vida. Sujetos y métodos: Estudio epidemiológico trasversal de la población de Madrid elegida aleatoriamente según censo. Entrevista telefónica. Población diana: 1.775 mayores de 55 años. Se preguntó sobre QSM, aspectos sociales, económicos, de salud y hábitos de vida. Se administraron el cuestionario de salud general de Goldberg (GHQ) y el cuestionario de calidad de vida COOP-Wonca. Resultados: Encontramos asociación estadísticamente significativa de las QSM con la edad, la orientación temporal, todas las variables relacionadas con la salud mental (depresión), la ansiedad, el sueño, la salud mental/GHQ y la calidad de vida. Se halló asociación con todas las variables que miden el dolor y con sentir soledad. No hubo asociación con enfermedades específicas, excepto con la alergia crónica y las ligadas al dolor. Los predictores de las QSM fueron la orientación temporal, la multimorbilidad, la salud mental/GHQ, la ansiedad, el dolor y el sentir soledad. Conclusiones: Las QSM son un síntoma con múltiples causas. Se asocian a menor rendimiento de la memoria, pero también a variables relacionadas con la salud, los aspectos sociales y el tipo de vida. Ante un paciente con QSM, que pueden deberse al deterioro cognitivo por enfermedad de Alzheimer, deben considerarse estas asociaciones para valorar dicho riesgo y saber cuándo es más necesario un seguimiento

Introduction: Subjective memory complaints (SMC) are considered predictor of cognitive impairment, but are also associated with other factors; social and lifestyle have been the least studied. Aim: To evaluate SMC and their association with epidemiological, health, social and lifestyle variables. Subjects and methods: Cross-sectional epidemiological study of the randomly selected population of Madrid. Telephone interview. Target population: 1,775 over 55 years of age. We asked about QSM, social, economic, health and lifestyle aspects. The Goldberg General Health Questionnaire (GHQ) and the COOP-Wonca Quality of Life Questionnaire were administered. Results: We found statistically significant association of SMC with age, temporal orientation, all variables related to mental health (depression), anxiety, sleep, mental health/GHQ, and quality of life. Association was found with all pain variables and with loneliness. There was no association with specific diseases, except chronic allergy and those linked to pain. The predictors of the SMC were temporal orientation, multimorbidity, mental health/GHQ, anxiety, pain and feeling lonely. Conclusions: SMC is a multi-caused symptom. They are associated with lower memory performance, but also with variables related to health, social aspects and lifestyle. When faced with a patient with SMC, which may be due to cognitive impairment because of Alzheimer’s disease, these associations should be taken into account to assess this risk and know when follow-up is most needed

BDNF Val66Met Polymorphism and Gamma Band Disruption in Resting State Brain Functional Connectivity: A Magnetoencephalography Study in Cognitively Intact Older Females.

The pathophysiological processes undermining brain functioning decades before the onset of the clinical symptoms associated with dementia are still not well understood. Several heritability studies have reported that the Brain Derived Neurotrophic Factor (BDNF) Val66Met genetic polymorphism could contribute to the acceleration of cognitive decline in aging. This mutation may affect brain functional connectivity (FC), especially in those who are carriers of the BDNF Met allele. The aim of this work was to explore the influence of the BDNF Val66Met polymorphism in whole brain eyes-closed, resting-state magnetoencephalography (MEG) FC in a sample of 36 cognitively intact (CI) older females. All of them were ε3ε3 homozygotes for the apolipoprotein E (APOE) gene and were divided into two subgroups according to the presence of the Met allele: Val/Met group (n = 16) and Val/Val group (n = 20). They did not differ in age, years of education, Mini-Mental State Examination scores, or normalized hippocampal volumes. Our results showed reduced antero-posterior gamma band FC within the Val/Met genetic risk group, which may be caused by a GABAergic network impairment. Despite the lack of cognitive decline, these results might suggest a selective brain network vulnerability due to the carriage of the BDNF Met allele, which is linked to a potential progression to dementia. This neurophysiological signature, as tracked with MEG FC, indicates that age-related brain functioning changes could be mediated by the influence of particular genetic risk factors.

Subjective Memory Complaints in healthy older adults: Fewer complaints associated with depression and perceived health, more complaints also associated with lower memory performance.

OBJECTIVES: (i) To analyze if general cognitive performance, perceived health and depression are predictors of Subjective Memory Complaints (SMC) contrasting their effect sizes; (ii) to analyze the relationship between SMC and objective memory by comparing a test that measures memory in daily life and a classical test of associated pairs; (iii) to examine if different subgroups, formed according to the MFE score, might have different behaviors regarding the studied variables. METHODS: Sample: 3921 community-dwelling people (mean age 70.41±4.70) without cognitive impairment. Consecutive non-probabilistic recruitment. ASSESSMENT: Mini Cognitive Exam (MCE), daily memory Rivermead Behavioural Memory Test (RBMT), Paired Associates Learning (PAL), Geriatric Depression Scale (GDS), Nottingham Health Profile (NHP). Dependent variable: Memory Failures Everyday Questionnaire (MFE). RESULTS: Two different dimensions to explain SMC were found: One subjective (MFE, GDS, NHP) and other objective (RBMT, PAL, MCE), the first more strongly associated with SMC. SMC predictors were NHP, GDS, RBMT and PAL, in this order according to effect size. Considering MFE scores we subdivided the sample into three groups (low, medium, higher scores): low MFE group was associated with GDS; medium, with GDS, NPH and RBMT, and higher, with age as well. Effect size for every variable tended to grow as the MFE score was higher. CONCLUSION: SMC were associated with both health profile and depressive symptoms and, in a lesser degree, with memory and overall cognitive performance. In people with fewer SMC, these are only associated with depressive symptomatology. More SMC are associated with depression, poor health perception and lower memory.

Quejas subjetivas de memoria en adultos jóvenes y su relación con rendimiento de memoria, depresión, calidad de vida y rasgos de personalidad / Subjective memory complaints in young adults and their relationship to memory performance, depression, quality of life and personality traits

Introducción y objetivos: Hay enfermedades degenerativas que pueden presentarse en adultos jóvenes y que afectan a la memoria; para ellas es importante un diagnóstico precoz. Las quejas subjetivas de memoria (QSM) son cada vez más frecuentes en adultos jóvenes, pero han sido o bjeto de pocos estudios. Nuestro objetivo es analizar la relación entre las QSM y el rendimiento objetivo de memoria, y determinar la asociación de las QSM con variables relacionadas con el estado de ánimo, los rasgos de personalidad y la percepción de la calidad de vida relacionada con la salud. Material y métodos: Estudiamos a 102 sujetos, de entre 23-64 años y sin deterioro cognitivo. Evaluación: Cuestionario de Fallos de Memoria, Escala de Memoria de Wechsler, Escala de Depresión-Ansiedad de Goldberg, Escala de Resiliencia y Cuestionario de Salud SF-12. Se realizaron correlaciones y regresión lineal jerárquica en tres bloques: variables sociodemográficas, de salud y de rendimiento de memoria. El tamaño del efecto se estudió con R2. Resultados: No hay correlación significativa entre QSM y edad, estudios, memoria auditiva y visual, ansiedad y resiliencia. Existe una correlación estadísticamente significativa con sintomatología depresiva (r=0,35; p<0,01) y percepción de salud (r=0,37; p<0,01). Varios factores del SF-12 y de personalidad se asociaron a las QSM. Entre todas las variables, la única con valor predictivo en la regresión fue Salud mental (F=3,561; p=0,004; R2=0,23). Conclusión: Nuestro estudio destaca el aspecto subjetivo de las QSM frente al objetivo. En adultos jóvenes que acuden a la consulta con QSM hay que valorar factores como la ansiedad la depresión, la falta de confianza en uno mismo y la calidad de vida, y no sólo el rendimiento de memoria(AU)

Introduction and aims: There are degenerative diseases in young adults that can affect memory; for these diseases an early diagnosis is important. Subjective memory complaints (SMC) are becoming more common in young adults but there are few studies on this topic. Our aim is to analyze the relationship between SMC and objective memory performance and to establish the association between SMC and mood, personality traits or perception of quality of life related to health. Methods: We studied 102 subjects, between 23-64 years without cognitive impairment. Assessment: Questionnaire of Memory Failures of Everyday, Wechsler Memory Scale, Goldberg Anxiety and Depression Scale, Resilience Scale and Health Survey (SF-12). Statistical analysis: Correlations and hierarchical linear regression in three blocks: sociodemographic factors, health factors and memory performance. The effect size was studied using R2. Results: No significant correlation between SMC and age, education, auditory and visual memory, anxiety and resilience, was found. There is a statistically significant correlation with depressive symptoms ('r' = 0.35, p<0.01) and health perception ('r' = 0.37, p<0.01). Several SF-12 and personality factors were associated with SMC. Among all variables, the only one with predictive value in the regression was 'Mental Health' (F=3.561, P=0.004, R2=0.23). Conclusion: Our study highlights the subjective aspect of the SMC against the objective one. Attending young adults with SMC we must evaluate factors such as anxiety, depression, lack of self-confidence and quality of life and not only memory performance(AU)

The Memory Failures of Everyday (MFE) test: normative data in adults.

UNLABELLED: One approach to the study of everyday memory failures is to use multiple-item questionnaires. The Memory Failures of Everyday (MFE) test is one of the most frequently used in Spain. Our objective is to provide normative data from the MFE in a sample of healthy, Spanish, adult participants for use in clinical practice. The sample consists of 647 employees at a large company ranging in age from 19-64 years-old. Everyday memory failures were evaluated by means of the MFE with the following response format: 0-2 (0 = never or rarely; 1 = occasionally, sometimes; 2 = frequently, often). RESULTS: Mean MFE = 15.25 (SD = 7.50), range 0-40. Correlation with age: .133 (p = .001); and with years of education: - .059 (n.s.). A constant increase in MFE was not observed across age groups (F = 4, 59; p = .003, eta2 = .02), but differences were revealed between the 19-29 and 40-49 age groups; no differences were observed between the remaining age groups. Only slight differences between men and women occurred, the women's mean being slightly higher than the men's, but the confidence intervals overlapped (F = 5, 71; p = .017, eta2 = .01). These results indicate that age, years of education, and sex had no significant effects. In light of the above, the sample was viewed as a whole when computing the percentiles reported here.

Un modo de abordar el estudio de los fallos de memoria de la vida diaria es utilizar cuestionarios de múltiples ítems. Uno de los más utilizados en nuestro medio es el Cuestionario de Fallos de Memoria de la Vida Cotidiana (MFE). Nuestro objetivo es presentar datos normativos para población adulta española del MFE para su utilización en la práctica clínica. La muestra está formada por 647 sujetos (19-64 años), trabajadores de una gran empresa. Se han evaluado los olvidos cotidianos mediante el MFE con la valoración 0-2 (0 = nunca, raras veces; 1 = pocas veces, algunas veces; 2 = con frecuencia, muchas veces). Resultados: La media del MFE es 15.25 (DT = 7.50), rango 0-40; correlación con la edad = .133 (p = .001); con años de estudios: - .059 (n.s.). Entre los grupos de edad no se observa un incremento constante en MFE (F = 4, 59; p = .003, η2 = .02), las diferencias se encuentran entre el grupo de 19-29 años y el de 40-49; no hay diferencias significativas entre las demás comparaciones. Respecto al sexo, hay pocas diferencias y los intervalos de confianza se solapan (F = 5, 71; p = .017 ; η2 = .01). Concluimos que no hay variaciones importantes por edad, sexo ni años de estudios. Teniendo esto en cuenta se considera al grupo como un todo para obtener los percentiles que se presentan (AU)

Nueva versión reducida del test de denominación de Boston para mayores de 65 años: aproximación desde la teoría de respuesta al ítem / A new shortened version of the Boston Naming Test for those aged over 65: an approach from item response theory

Introducción. Uno de los tests más utilizados para la evaluación de la afasia en la práctica clínica es el test de denominación de Boston (BNT), una prueba clásica en la que se presentan 60 láminas con dibujos en blanco y negro que valoran la capacidad de los sujetos para denominar dichos dibujos. Pese a su bondad psicométrica, resulta necesario reducir el número de ítems de la prueba con el fin de disminuir su tiempo de aplicación. Sujetos y métodos. Se reclutó una muestra de 547 sujetos mayores de 65 años a los que se les aplicó un protocolo de evaluación neuropsicológica, que incluía el BNT, para determinar sus estados cognitivos; 405 sujetos no presentaron alteraciones cognitivas relevantes, frente a 142 sujetos que fueron diagnosticados de deterioro cognitivo leve. Resultados. La reducción del número de ítems se realizó de acuerdo con los supuestos de la teoría de respuesta al ítem. Puesto que tanto la edad como el nivel educativo mostraron un efecto significativo en el rendimiento de la prueba, ambas variables fueron utilizadas para hallar los puntos de corte de la nueva versión reducida. Ésta presentó una adecuada fiabilidad (alfa = 0,765) y una elevada correlación con la prueba original (r = 0,876). Conclusiones. La nueva versión reducida consta de 15 ítems ordenados en función de su dificultad. Se trata de una tarea con un elevado poder discriminativo de utilidad en la clínica diaria para la detección de alteraciones del lenguaje en personas mayores (AU)

Introduction. One of the tests that is mostly widely used to evaluate aphasia in clinical practice is the Boston Naming Test (BNT), a classic test in which 60 black and white pictures are presented to subjects in order to evaluate their capacity to put a name to such pictures. Despite its psychometric goodness, the number of items in the test has to be reduced in order to lower the time required to apply it. Subjects and methods. Researchers recruited a sample of 547 subjects over the age of 65, who were then administered a neuropsychological evaluation protocol, including the BNT, to determine their cognitive statuses. No relevant cognitive alterations were observed in 405 subjects versus 142 who were diagnosed with mild cognitive impairment. Results. The number of items was reduced in accordance with the premises of the item response theory. Since both age and level of schooling were found to have a significant effect on performance in the test, the two variables were used to find the cut-off points of the shortened version. This new version presented an adequate degree of reliability (alpha = 0.765) and a high correlation with the original test (r = 0.876). Conclusions. The new shortened version consists of 15 items that are ordered according to the degree of difficulty. It is a task with a high level of discriminating power that is useful in day-to-day clinical practice for detecting alterations in the anguage of the elderly (AU)

INTRODUCTION: One of the tests that is mostly widely used to evaluate aphasia in clinical practice is the Boston Naming Test (BNT), a classic test in which 60 black and white pictures are presented to subjects in order to evaluate their capacity to put a name to such pictures. Despite its psychometric goodness, the number of items in the test has to be reduced in order to lower the time required to apply it. SUBJECTS AND METHODS: Researchers recruited a sample of 547 subjects over the age of 65, who were then administered a neuropsychological evaluation protocol, including the BNT, to determine their cognitive statuses. No relevant cognitive alterations were observed in 405 subjects versus 142 who were diagnosed with mild cognitive impairment. RESULTS: The number of items was reduced in accordance with the premises of the item response theory. Since both age and level of schooling were found to have a significant effect on performance in the test, the two variables were used to find the cut-off points of the shortened version. This new version presented an adequate degree of reliability (alpha = 0.765) and a high correlation with the original test (r = 0.876). CONCLUSIONS: The new shortened version consists of 15 items that are ordered according to the degree of difficulty. It is a task with a high level of discriminating power that is useful in day-to-day clinical practice for detecting alterations in the language of the elderly.

The memory failures of everyday questionnaire (MFE): internal consistency and reliability.

The Memory Failures of Everyday Questionnaire (MFE) is one of the most widely-used instruments to assess memory failures in daily life. The original scale has nine response options, making it difficult to apply; we created a three-point scale (0-1-2) with response choices that make it easier to administer. We examined the two versions' equivalence in a sample of 193 participants between 19 and 64 years of age. The test-retest reliability and internal consistency of the version we propose were also computed in a sample of 113 people. Several indicators attest to the two forms' equivalence: the correlation between the items' means (r = .94; p < .001) and the order of the items' frequencies (r = .92; p < .001). However, the correlation between global scores on the two forms was not very high (r = .67; p < .001). The results indicate this new version has adequate reliability and internal consistency (r(xx) = .83; p < .001; alpha = .83; p < .001) equivalent to those of the MFE 1-9. The MFE 0-2 provides a brief, simple evaluation, so we recommend it for use in clinical practice as well as research.
