EspañolEl objetivo de esta investigación fue analizar la adecuación psicométrica del Test d2 para su uso en Costa Rica. Una muestra de 445 individuos con edades entre 18 y 47 años, 58% mujeres y 42% hombres, contestaron la prueba d2; 50 de ellos completaron la prueba una segunda vez y 40 respondieron también las pruebas Test del Trazo, Test de Colores y Palabras de Stroop, Span de Dígitos, Búsqueda de Símbolos, Claves y Cancelación. Fueron evaluadas la consistencia interna, la estabilidad temporal y las evidencias de validez basadas en relaciones con otras variables y en la estructura interna. Los puntajes más fiables fueron los siguientes: total de respuestas (TR), total de aciertos (TA), índice de efectividad en la prueba (TOT) e índice de concentración (CON), con resultados del alfa de Cronbach y de fiabilidad test-retest en el rango de .90 a .97. Las correlaciones con pruebas que evalúan atención sostenida y selectiva, velocidad de procesamiento, precisión y control inhibitorio sugieren evidencias de validez para los puntajes CON, TR, TA y O (errores de omisión). Además, el aumento de edad está relacionado a la disminución de los puntajes TA y CON, en especial. Se discuten los hallazgos respecto a la estructura factorial de la prueba. Los resultados corroboran estudios previos e indican puntajes válidos del d2 para evaluar individuos de nivel universitario de Costa Rica.EnglishIn this research, some psychometric properties of the d2 test were analyzed for its use in Costa Rica. A total of 445 participants aged between 18 and 47 years, 58% women and 42% men, completed the d2 test; a subset of 50 participants completed the test a second time, and 40 participants answered the additional tests: Trail Making Test, Stroop Test, Digit Span, Symbol Search, Coding and Cancellation. Internal consistency, temporal stability and validity evidences based on relations to other variables and based on the internal structure were evaluated. The most reliable scores were total number of responses (TR), total number of correct characters canceled (TA), effectiveness index (TOT) and concentration index (CON), with Cronbach’s Alpha results and test-retest reliability ranged from .90 to .97. Correlations with tests that evaluate sustained and selective attention, processing speed, accuracy, and inhibitory control suggest validity evidence for the CON, TR, TA, and O (omission errors) scores. In addition, aging is especially related to the decrease in TA and CON scores. The findings regarding the factorial structure of the test are discussed. The results corroborate previous studies and indicate validity evidence for d2 test scores for evaluating Costa Rican university students and graduates.

Oxford Happiness Questionnaire

The Oxford Happiness Questionnaire short-form (Hills & Argyle, 2002) is an 8-item measure of happiness. This study evaluated the internal consistency reliability and test-retest reliability of the Oxford Happiness Questionnaire short-form among 55 Northern Irish undergraduate university students who completed the measure on two occasions separated by two weeks. Internal consistency of the measure was satisfactory at both Time 1 (alpha = .62) and Time 2 (alpha = .58). Stability across the two administrations was satisfactory (r = .69), and there was no significant change between Time 1 (M = 34.5, SD = 5.4) and Time 2 (M = 34.6, SD = 5.2). These data support the internal consistency reliability and short-term test-retest reliability of the Oxford Happiness Questionnaire short-form.

Test Retest Reliability

Previous research has shown that scores on private self-consciousness were related to increased test-retest reliability and internal consistency of responses. To extend these findings to other measures, split-half reliability and Cronbach alpha 84 women and 27 men completed the Self-consciousness Scale and the NEO-Five Factor Inventory. It was hypothesized that subjects scoring high in private self-consciousness would show greater split-half reliability and homogeneity. The results did not support the hypotheses as scores for private self-consciousness were not significantly related to split-half reliability or homogeneity on the NEO-Five Factor Inventory. The present results, combined with previous findings, suggest that private self-consciousness is related to temporal stability of test scores but not to estimates of reliability associated with parallel forms of a test or to internal consistency.

Reliability Coefficients

The reliability of event-related brain potential (ERP) scores depends on study context and how those scores will be used, and reliability must be routinely evaluated. Many factors can influence ERP score reliability, and generalizability (G) theory provides a multifaceted approach to estimating the internal consistency and temporal stability of scores that is well suited for ERPs. G-theory’s approach possesses a number of advantages over classical test theory that make it ideal for pinpointing sources of error in scores. The current primer outlines the G-theory approach to estimating internal consistency (coefficients of equivalence) and test-retest reliability (coefficients of stability). This approach is used to evaluate the reliability of ERP measurements. The primer outlines how to estimate reliability coefficients that consider the impact of the number of trials, events, occasion, and group. The uses of two different G-theory reliability coefficients (i.e., generalizability and dependability) in ERP research are elaborated, and a dataset from the companion manuscript, which examines N2 amplitudes to Go/NoGo stimuli, is used as an example of the application of these coefficients to ERPs. The developed algorithms are implemented in the ERP Reliability Analysis (ERA) Toolbox, which is open-source software designed for estimating score reliability using G theory. The toolbox facilitates the application of G theory in an effort to simplify the study-by-study evaluation of ERP score reliability. The formulas provided in this primer should enable researchers to pinpoint the sources of measurement error in ERP scores from multiple recording sessions and subsequently plan studies that optimize score reliability.

The study was designed to investigate the effects of an acute naturalistic stressor, namely, examination of stress on memory, attention and cognition in healthy human volunteers. Fifty-three students participated in this study. All the volunteers were assessed for their neuropsychological states, which are memory, attention and cognition, during non-examination and examination period. The neuropsychological tests used in this study were- logical memory test, digit span test, letter cancellation test, trail making test and Stroop test. It was revealed that there was significant difference (p<0.05) in the score of logical memory II, backward and total score of digit span, time taken to complete letter cancellation test and score in part C of Stroop test in the exam period. The present study thus demonstrated that acute naturalistic stress improves attention while impairs delayed memory retrieval and cognition.Bangladesh Pharmaceutical Journal 20(1): 14-19, 2017

In the past two decades, there has been a growing theoretical and empirical interest on the role of shame, namely internal shame, on the conceptualization of human functioning and several interpersonal and emotional problems. The current study explores the psychometric properties of the Portuguese version of the Internalized Shame Scale (ISS), a self-report measure which assesses trait shame, composed by an Internal Shame subscale, measuring internalized shame, and a Self-Esteem subscale. The factor structure, internal consistency, test-retest reliability and convergent and discriminant validity for both subscales, are presented, in a sample of 385 college students. The Principal Components Analyses reveal that both Internal Shame and Self-Esteem subscales present a one-dimensional structure which explains, respectively, 48.54% and 57.7% of the variance. The subscales present high internal consistency, with high Cronbach'alphas (.95 and .85) and moderate to high item-total correlations. The two subscales present an excellent temporal stability. Convergent and discriminant validity of the subscales was corroborated through the moderate correlations with a measure of shame and of social comparison, and through the low and moderate correlations with the subscales depression, anxiety, and stress. The Portuguese version of the ISS is a valid and reliable instrument to measure internalized shame.

AbstractInterest in cosmetic surgery is increasing, with rhinoplasty being one of the most popular surgical procedures. It is essential that surgeons identify patients with existing psychological conditions before any procedure. This study aimed to develop and validate the Interest in Aesthetic Rhinoplasty Scale (IARS). Four studies were conducted to develop the IARS and to evaluate different indices of validity (face, content, construct, criterion, and concurrent validities) and reliability (internal consistency, split-half coefficient, and temporal stability) of the scale. The four study samples included a total of 463 participants. Statistical analysis revealed satisfactory psychometric properties in all samples. Scores on the IARS were negatively correlated with self-esteem scores (r = –0.296; p < 0.01) and positively associated with scores for psychopathologic symptoms (r = 0.164; p < 0.05), social dysfunction (r = 0.268; p < 0.01), and depression (r = 0.308; p < 0.01). The internal and test–retest coefficients of consistency were found to be high (α = 0.93; intraclass coefficient = 0.94). Rhinoplasty patients were found to have significantly higher IARS scores than nonpatients (p < 0.001). Findings of the present studies provided evidence for face, content, construct, criterion, and concurrent validities and internal and test–retest reliability of the IARS. This evidence supports the use of the scale in clinical and research settings.

Memory, attention, and cognitive dysfunction are psychopathological conditions which most commonly occur after menopause. Different clinical studies revealed a shred of substantial evidence that oxidative stress and estrogen are interlinked in various cognitive dysfunction, including memory impairment, age-related dementia, and Alzheimer's disease. There is a higher chance of developing cardiovascular disease after menopause. Sharp declines in concentrations of circulating estradiol and estrone are associated with menopause. Estrogen replacement therapy (ERT) enhances the blood circulation to the hippocampus and cortex, providing the optimum environment for the growth and survival of cholinergic neurons. Hence, it improves hippocampal neuron density and ultimately contributes to synaptic plasticity in the hippocampus enhances short and long-term memory. In this study, we assessed memory, attention, and cognition function between pre- and post-menopausal groups. After preliminary screening and applying exclusion criteria, fifteen premenopausal women and fifteen postmenopausal women were finally selected. Different neuropsychological tests such as logical memory test, digit span test, letter cancellation test, trail making test and Stroop test were performed to evaluate the memory, attention, and cognition status. Blood estradiol level was also assessed by using commercial kits. Significant difference (p<0.05) was found in LM-II in logical memory test, digit span test (backward), letter cancelation test, TMT-B in trail making test, the score of part C in stroop test between premenopausal and postmenopausal women. Serum oestradiol concentration (pg/ml) was significantly lower (p<0.001) in postmenopausal women (44.18±10.52) than premenopausal women (175.48 ± 43.20). The current study demonstrates the memory decline and cognitive dysfunction in postmenopausal women and there is a significant difference in estradiol level between pre and postmenopausal women. Estrogen has many neurotrophic actions in the brain and helps to improve memory and cognition. Therefore, estrogen replacement therapy, dietary supplements or a drug having an agonistic effect on estrogen receptors might improve the status of memory, attention, and cognitive function in postmenopausal women.

The Raven Standard Progressive Matrices was administered to a sample of 6,529 children in Kuwait ranging in age from 8 to 15 years. Test-retest reliability ( N = 968) ranged between .69 and .85, while Cronbach coefficients alpha ranged from .88 to .93, showing from acceptable to good temporal stability and from good to high internal consistency. The loadings of the five sets of matrices on the only salient factor ranged from .73 to .89 indicating the good factorial validity of the scale. The test seems useful in the Kuwaiti context.

Intensive Care Unit delirium, insomnia, anxiety, and frontal/dysexecutive disorders have been described following COVID-19 infection. The aim of this case study was to re-evaluate the neuropsychological pattern in a series of patients with COVID-19 outcomes. We retrospectively evaluated 294 patients admitted to the Istituti Clinici Scientifici Maugeri of Lumezzane (Brescia) (May–September 2020). Neuropsychological assessment was available for 12 patients. We extracted clinical, functional data (FIM and Barthel Index score) and neuropsychological tests (MMSE, Trail making a-b, verbal fluency test, digit span, prose memory test, Frontal Assessment Battery, clock drawing test, Rey–Osterrieth complex figure, Tower of London test). The results were analyzed by Spearman (rho) correlation. Six patients presented dysexecutive alterations even in the presence of normal overall cognitive functioning. Forward digit span score was directly correlated to FIM value at admission (p = 0.015) and inversely correlated to delta FIM (p = 0.030) and delta Barthel Index (p = 0.025). In our experience, subclinical cognitive alterations were present in 4% of patients recovering from COVID-19 pneumonia. The possible correlation between verbal memory and frontal functions, and the degree of functional impairment at admission and its subsequent improvement, underscores the importance of an adequate cognitive evaluation and rehabilitation.

In this study the Eating Disorder Inventory-3 was adapted to Spanish and analyzed the internal psychometric properties of the test in a clinical sample of females with eating disorders. The results showed a high internal consistency of the scores as well as high temporal stability. The factor structure of the scale composites was analyzed using confirmatory factor analysis. The results supported the existence of a second-order structure beyond the psychological composites. The second-order factor showed high correlation with the factor related to eating disorders. Overall, the Spanish version of the EDI-3 showed good psychometric qualities in terms of internal consistency, temporal stability and internal structure.
