The aim of this study was to examine the preliminary evidence of validity of the Research Self-Efficacy Scale (RSE) through the analysis of item contents. A sample of ten research psychologists (70% male; Mage = 47.2 years old), and 34 Peruvian college students (> 70% female), both undergraduate (n = 19) and graduate (n = 15) was assessed. The researchers evaluated the relevance and clarity of the items, and the students, the clarity of the RSE statements. The answers given by the judges were systematized through Aiken’s V with confidence intervals, obtaining favorable results. In conclusion, the RSE exhibits favorable evidence regarding the representativity of the items. The practical implications of the findings are discussed here.

The purpose of this study is to report evidence of construct validity and reliability of a new self-report instrument that measures mindfulness and equanimity in a Spanish speaking population. An initial pool of 26 items was evaluated by 17 experts from Spain and Latin America and modified on the basis of their comments. The resulting list of 21 items was administered to 746 university students in Mexico and Peru. Their responses were analyzed using Unweighted Least Squares (ULS) with promin rotations. Two factors were identified, mindless and mindful, with factor loadings ranging from .36 to .65. The reliability coefficients for the first and second factors were .78, and .82 respectively. The inter-factors correlation was -.51. The results indicate clear evidence of convergent and discriminative validity.

This study describes epistemological beliefs from students in the Degree of Pedagogy at the University of Barcelona (Spain), and analyzes differences inthese beliefs according to their year of study, gender, and age. To do so, the psychometric properties (construct validity and internal consistency) of SchommerEpistemological Questionnaire (1990) were estimated. 229 students participated.Results show that the reliability of the instrument is moderate (a = .653), and the factorial structure revealed validates the epistemological model proposed by Schommer. Furthermore, the results indicate that final year student beliefs aremore sophisticated than first year student beliefs in respect to learning ability andto the structure and certainty of knowledge. Differences were also found owningto the student’s gender, but not to age.

El objetivo del estudio fue obtener evidencias de validez de la estructura interna del Cuestionario de Autorregulación del Aprendizaje (Learning Self Regulation Questionnaire; LSRQ) y verificar la invarianza métrica comparada con un estudio previo. Los participantes fueron 237 estudiantes universitarios de los tres primeros ciclos académicos de una universidad privada, procedentes de tres ciudades del Perú (dos del norte y una de Lima). El análisis se realizó mediante un análisis factorial semiconfirmatorio, especificando como matriz de comparación (a) la configuración derivada de un estudio previo, y (b) la estimación libre de las cargas factoriales. Los resultados indican que dos dimensiones representan satisfactoriamente la estructura del instrumento; pero la invarianza métrica respecto a un estudio previo no fue satisfactoria. La reespecificación del modelo, medi...

Design of a measurement instrument is a multidisciplinary task. To measure some trait without major implications - depending on the application you are given- it will be needed specialists in construct, statistical analysts, test designers, and language specialists. In fact, specialized knowledge is required for the design or adaptation of instruments that have broad repercussions, such as, validating a medical diagnostic instrument. Metric characteristics of an instrument are its validity and reliability. Validity refers to the accuracy of physical instruments and the reliability of measurement precision. In addition, validities that are representative of this characteristic are content, construct and criterion validity, while reliability of the instrument increases when errors are identified and these can be controlled.

Julcani es una de las principales minas de Huancavelica - Perú, fue trabajada desde el tiempo de la colonia, habiendo sido abandonada varias veces por distintas empresas. En 1953 se funda la Compañía de Minas Buenaventura SAA con la adquisición de mina Julcani, la misma que viene operando actualmente. La mineralización de Julcani está emplazada en rocas volcánicas a manera de vetas angostas entre 5cm a 2m, y actualmente se explotan vetas con achos entre 5cm y 50cm. Este yacimiento es un ejemplo típico de un depósito con mineralización íntimamente relacionada a la actividad volcánica y es explotado de manera convencional por el método de corte y relleno ascendente. El zoneamiento de la mineralización se ubica en una franja metalogenética de plata-plomo, los fluidos mineralizantes fueron posiblemente alimentados por el domo de Acchilla, hacia su extremo Norte y en profundida...

It aimed to gather evidence psychometrics of the Family Resiliency Assessment Scale (FRAS). Two studies were carried out with participants from different states in Brazil. In the first (n = 314), the majority female (56.4%), with an exploratory factor analysis being performed, which suggested a three-factorial structure, with adequate precision. The study 2 (n = 336), the majority female, who undergoing hemodialysis (46.4%). Confirmatory factor analysis corroborated the structure tetra-factorial (family communication and problem solving, maintaining a positive outlook, using social resources and economics, and family spirituality). Therefore, the results showed that the reduced version of FRAS can be an alternative to assess family resilience and its correlates.

The purpose of this study was to provide evidence of validity and reliability for the Barnes and Olson’s (1982) Parent-Adolescent Communication Scale among university students from Lima, aged 16 to 25. Participants were 255 students (162 females) from two universities. An exploratory factor analysis was performed to assess the viability of bi-factor and tri-factor structures. This exploratory factor analysis supported the two-factor structure originally proposed for this instrument (open communication and problem communication). Both in the father-adolescent and in the mother-adolescent version, obtained Cronbach’s alpha values were high (ranging between .80 and .90). The structural model also showed good fit indexes. This confirms the reliability and validity of this instrument in the sample under study.
