Honey-Alonso Learning Styles Questionnaire: New psychometric evidences in Argentinean population / Cuestionario Honey-Alonso de Estilos de Aprendizaje: Nuevas evidencias psicométricas en población argentina

Abstract The study is aimed at analyzing psychometric features of the local version of the Honey-Alonso Learning Styles Questionnaire. First, the inner structure of the scale is examined by means of a confirmatory factor analysis and an analysis of factorial invariance, splitting the sample by faculty. Second, internal consistency coefficients of the dimensions are analyzed and compared to previous results. Third, external convergent validity evidences are considered, regarding scores obtained from a learning approach scale which was used as an external criterion. Findings show an adequate model fit, even employing different estimation methods. Furthermore, the factorial invariance analysis verifies the metrical equivalence of the model. The internal consistency study finds acceptable values. The dimensions' stability reliability indices do not verify significant differences between test and retest. Finally, the convergent validity evidences analyses show positive associations between learning styles and the Deep learning approach on the one hand, and negative associations between the Surface approach and learning styles on the other, as reported in previous studies. Results are discussed on the grounds of the theoretical and empirical background.

Resumen En el presente trabajo se examinan las propiedades psicométricas de la versión argentina del Cuestionario Honey-Alonso de Estilos de Aprendizaje (CHAEA). Primero se analiza la estructura interna de la escala mediante un análisis factorial confirmatorio y de invarianza factorial, segmentando la muestra según facultad; luego se estudia la consistencia interna de las dimensiones confirmadas y se comparan los resultados con los obtenidos en estudios previos; posteriormente se examina la estabilidad temporal de las puntuaciones de cada dimensión; y, por último, se estudian las evidencias de validez concurrente con otra escala que evalúa enfoques de aprendizaje. Los resultados del análisis factorial confirmatorio muestran un adecuado ajuste del modelo testeado a partir de distintos métodos de estimación, mientras que con el análisis de invarianza factorial se comprueba la equivalencia métrica del modelo. Asimismo, los índices de consistencia interna son aceptables, aunque el análisis de estabilidad temporal de las dimensiones no comprueba diferencias significativas entre la primera y segunda administración del instrumento. Finalmente, en consonancia con hallazgos previos, las evidencias de validez concurrente exhiben asociaciones positivas entre los estilos de aprendizaje y el enfoque profundo, así como asociaciones negativas entre los estilos y el enfoque superficial. Al final se discuten los resultados a partir de antecedentes teóricos y empíricos.

Multi-joint rate of force development testing protocol affects reliability and the smallest detectible difference.

Isometric tests have been used to assess rate of force development (RFD), however variation in testing methodologies are known to affect performance outcomes. The aim of this study was to assess the RFD in the isometric squat (ISqT) using two test protocols and two testing angles. Eleven participants (age: 26.8 ± 4.5 years, strength training experience: 7.1 ± 3.03 years) completed test and retest sessions one week apart, whereby two test protocols with respect to duration and instructions were compared. Isometric peak force (ISqTpeak) and isometric explosive force (ISqTexp) tests were assessed at two joint angles (knee flexion angle 100° and 125°). Force-time traces were sampled and subsequently analysed for RFD measures. Average and instantaneous RFD variables did not meet reliability minimum criteria in ISqTpeak at 100° or 125°. The ISqTexp test at 100° met reliability criteria in the RFD 0-200 and 0-250ms variables. The ISqTexp test at 125° met reliability criteria in the RFD 0-150, 0-200 and 0-250ms variables. Force-time characteristics were optimized at the higher knee joint angle. Average and instantaneous RFD measures obtained using a traditional peak force test do not meet basic reliability criteria. Researchers assessing multi-joint RFD should employ the explosive RFD test protocol as opposed to the traditional isometric peak force protocol.

Familiarization, validity and smallest detectable difference of the isometric squat test in evaluating maximal strength.

Isometric multi-joint tests are considered reliable and have strong relationships with 1RM performance. However, limited evidence is available for the isometric squat in terms of effects of familiarization and reliability. This study aimed to assess, the effect of familiarization, stability reliability, determine the smallest detectible difference, and the correlation of the isometric squat test with 1RM squat performance. Thirty-six strength-trained participants volunteered to take part in this study. Following three familiarization sessions, test-retest reliability was evaluated with a 48-hour window between each time point. Isometric squat peak, net and relative force were assessed. Results showed three familiarizations were required, isometric squat had a high level of stability reliability and smallest detectible difference of 11% for peak and relative force. Isometric strength at a knee angle of ninety degrees had a strong significant relationship with 1RM squat performance. In conclusion, the isometric squat is a valid test to assess multi-joint strength and can discriminate between strong and weak 1RM squat performance. Changes greater than 11% in peak and relative isometric squat performance should be considered as meaningful in participants who are familiar with the test.

Stability of Usmeq-I In Measuring Emotional Intelligence In Medical Students

Objective: Emotional Intelligence (EI) is described as the ability to perceive, express, understand, motivate, control and regulate emotion. The USM Emotional Quotient Inventory (USMEQ-i) was designed to measure EI and it was found to be a reliable and valid tool in a sample of prospective medical students. The objective of this study is to determine stability of the USMEQ-i to measure EI at different time and occasions. Methods: A prospective cohort study was done on 196 first year medical students. It was administered to the medical students at four different intervals. The Cronbach’s alpha and intra-class correlation analysis were applied to measure the internal consistency and agreement level across the intervals. The analysis was done using Statistical Package for Social Sciences (SPSS) version 18. Results: A total of 196 first year medical students participated in this study. Its overall Cronbach’s alpha value across intervals ranged between 0.94 and 0.97. The Cronbach’s alpha values of emotional control, emotional maturity, emotional conscientiousness, emotional awareness, emotional commitment, emotional fortitude, and emotional expression scale ranged between 0.59 and 0.91. The Cronbach’s alpha value for the faking index scale ranged from 0.76 to 0.89. The ICC coefficient values for EI total score was 0.83, EI domain score ranged between 0.62 and 0.76 and the faking index score was 0.76. Conclusion: The USMEQ-i has demonstrated a good level of stability and internal consistency to measure EI at different time and occasions. It is a promising psychometric instrument that can be used to measure EI

Test-retest Reliability of Tetrax Posturographic Balance Assessment System in Elderly / 中国康复理论与实践

@#Objective To assess the test-retest reliability of Tetrax posturographic balance assessment system in determining the balance function in elderly individuals. Methods 22 elderly subjects (66~84 years old) were measured with the stability index (ST), the spectrum analysis of postural sway and the weight distribution harmony between two foots or heels and toe parts in standing on solid surface with eyes open using Tetrax balance system. All tests were repeated 1 week after the initial test and each subject underwent the test under the same instructions and conditions. The intraclass correlation coefficients (ICC) were used to determine the test-retest reliability. Results ICC of all balance functional parameters ranged from 0.797~0.882 (P<0.01). Conclusion The posturographic balance assessment system has good test-retest reliability for determining the balance function in elderly people.

Test-Retest Reliability of the Digijump Machine.

Repetitive jumping has been identified as a possible exercise modality able to provide sufficient stimulus to improve bone health. However, it is necessary to establish whether repetitive jumping can elicit a consistent physiological response with the ablity to monitor work rate. The purpose of this investigation was to determine the stability reliability of the Digijump device for the commonly used laboratory measures of oxygen uptake (VO2), heart rate (HR), and rate of perceived exertion (RPE). College-aged individuals (N = 17) completed two 3-min repetitive jumping bouts on the Digijump machine (120 jumps per minute, jump height = 1.27 cm) at least seven days apart. Stability reliability was calculated using the intraclass correlation coefficient derived from 1-way ANOVA. Absolute VO2 displayed the highest test-retest reliability (0.95), while the coefficient for relative VO2 was also acceptable (0.71). The test-retest reliability coefficients for HR (0.89), and RPE (0.75) were determined to be within acceptable limits. Coefficients for all variables compared well with the stability reliability reported for other ergometers such as the Stairmaster, treadmill, and cycle. This data represent an important step in determining the validity of the Digijump machine for physiological testing.
