Dicha adaptación se administró a una muestra de 535 niños (269 niños y 266 niñas) con un rango de edades de 8-16 años, pertenecientes a tres colegios del área metropolitana de Bucaramanga. Los resultados del análisis factorial confirmatorio indican un buen ajuste al modelo de cuatro factores que ha sido descrita para otros idiomas y adaptaciones. El test presentó una fiabilidad satisfactoria para la escala total (α = 0.82) y para la escala de agresividad física (α = 0.75), mientras que para las demás escalas varía en función de la edad, no siendo recomendable su aplicación en edades inferiores a los 12 años. Al analizar los efectos del sexo sobre la agresividad, se verificó que dicho efecto se debía exclusivamente a las diferencias en agresividad física. Finalmente, se pone de manifiest...

The novelty of the approach is its use of external information, in which multiple factor scores and general factor scores are related to relevant external variables or criteria. The unival package's implementation comes from a series of procedures put forward by Ferrando and Lorenzo-Seva (2019) and new methodological developments proposed in this article. We assess models fitted using unival by means of a simulation study extending the results obtained in the original proposal. Its usefulness is also assessed through a real-world data example. Based on these results, we conclude unival is a valuable tool for use in applications in which the dimensionality of an item set is to be assessed.

Currently, only English and Spanish versions of this questionnaire are available. The objective of this study is to validate a French version of the BMRQ.Methods.The original BMRQ was translated and adapted into an international French version. The questionnaire was then administered through an online survey aimed at adults aged over 18 years who were fluent in French. Statistical analyses were performed and compared to the original English and Spanish version for validation purposes.Results.A total of 1,027 participants completed the questionnaire. Most responses were obtained from France (89.4%). Analyses revealed that congruence values between the rotated loading matrix and the ideal loading matrix ranged between 0.88 and 0.96. Factor reliabilities of subscales (i.e...

For reasons discussed in the article, however, MSA is hardly used nowadays in this context. In our view, this is unfortunate. In the present proposal, we first discuss the foundation and rationale of MSA from a ‘modern’ FA view, as well as its usefulness in the item selection process. Second, we embed the index within a robust approach and propose improvements in the preliminary item selection process. Third, we implement the proposal in different statistical programs. Finally, we illustrate its use and advantages with an empirical example in personality measurement.

However little is known about individual differences in how people experience reward in music-related activities. The goal of the present study was to describe the main facets of music experience that could explain the variance observed in how people experience reward associated with music. To this end we developed the Barcelona Music Reward Questionnaire (BMRQ), which was administrated to three large samples. Our results showed that the musical reward experience can be decomposed into five reliable factors: Musical Seek-ing, Emotion Evocation, Mood Regulation, Social Reward, and Sensory-Motor. These factors were corre-lated with socio-demographic factors and measures of general sensitivity to reward and hedonic experience. We propose that the five-factor structure of musical reward experience might be very relevant in the study of psychological and neural bases of emotion and plea-sure associated to music.

However, many authors have mentioned that the differences in the prediction power of broad and narrow personality measures must be taken into account. We develop and validate a scale to assess the anxiety encountered when taking a statistics course. We designed the inventory as a set of 24 positive sentences that measure three subscales: Examination Anxiety , Asking for Help Anxiety and Interpretation Anxiety . In addition, as the three dimensions correlated with each other, they were considered related subscales from an overall scale, which measures statistical anxiety. Results show that these specific measures of anxiety about statistics have a significant relationship with academic performance in statistics whereas broader measures of anxiety or neuroticism do not.

The overall analysis should start with an exploratory factor analysis that explores the data and establishes a hypothesis for the factor model in the population. Then, the analysis process should be continued with a confirmatory factor analysis to assess whether the hypothesis proposed in the exploratory step is plausible in the population. To carry out the analysis, researchers usually collect a single sample, and then split it into two halves. As no specific splitting methods have been proposed to date in the context of factor analysis, researchers use a random split approach. In this paper we propose a method to split samples into equivalent subsamples similar to one that has already been proposed in the context of multivariate regression analysis. The method was tested in simulation studies and in real datasets.

The present study analyzes the impact of social desirability on measures of direct and indirect aggression and on the relationships between both kinds of aggression with impulsivity, using a method that enables the content factors of the measures to be isolated from social desirability. Results showed that aggression measures are highly affected by social desirability and that the relationships between the two forms of aggression and impulsivity are due to the content measured by the tests and not to a common social desirability factor.

Methods Prospective, observational, multicenter study for which 914 patients were recruited from 15 Spanish hospitals. Exploratory and confirmatory factor analyses, validity and reliability analyses were conducted. Results Factor-analytic results indicated a 4-factor structure of the Spanish version of the Mini-MAC. Three subscales have psychometric properties similar to those of Helplessness, Anxious preoccupation, and Cognitive avoidance of the original the Mini-MAC. The Fighting spirit and the Fatalism subscales were combined on the Positive attitude scale. The four factor-derived scale scores exhibited acceptable accuracy for individual measurement purposes, as well as stability over time in test-retest assessments at 6 months. V...

When full balance is achieved, ACQ is not expected to affect external validity. Otherwise, attenuated estimates are expected to appear if no control methods such as Lorenzo-Seva & Ferrando’s (2009) are used. Method: Expected results were derived analytically. Subsequently, a simulation was carried out to assess (a) how ACQ impacted external validity and (b) how validity estimates behaved when ACQ was corrected. Two illustrative examples are provided. RESULTS A sizable number of items and/or high content loadings tended to decrease ACQ’s impact on validity estimates, making the empirical coefficient closer to its structural value. Furthermore, when scales were well balanced, the controlled and uncorrected scores were close to each other, and led to unbiased validity estimates. When the sc...
