    Factorial analysis and gender invariance of GPIUS2 scale and evaluation of Caplan’s cognitive-behavioral model of problematic Internet use in adolescents
    (Universidad de Murcia. Servicio de Publicaciones, 2022) Marzo, Juan; García Oliva, Carlos; Piqueras, Jose A
    Caplan's (2010) revised cognitive-behavioral model of Problem-atic Internet Use (PIU) has become one of the most promising theoretical frameworks on such behavior in the last decade. The Generalized Prob-lematic Internet Use Scale (GPIUS2) (Caplan, 2010) has been adapted and validated for use with Spanish adolescents, but gender invariance has not been tested yet in this country. The present study focuses on three objec-tives: to confirm the factorial structure of GPIUS2, to analyze gender in-variance, and to test Caplan’s theoretical model, in a sample of Spanish ad-olescents. A cross-sectional study was carried out. The sample was com-posed of 909 participants from Spain, aged between 12 and 18 years (Mean age = 14.2, SD = 1.6). The results indicated a good fit of the GPIUS2 fac-tor structure and gender factorial invariance. Moreover, the cognitive-behavioral model fit the data. GPIUS2 has a very good structure and pre-sents gender factorial invariance, which favors its application in Spanish adolescent population. This study supports the cognitive-behavioral model of PIU.

    Propiedades psicométricas de la escala de calidad percibida y satisfacción del deporte municipal
    (Universidad de Murcia. Servicio de publicaciones, 2022) Reyes Robles, Marina; Ceballos Gurrola, Oswaldo; Medina Rodríguez, Rosa Elena; Rojo Villa, Jesús Alfredo; López Esquerra, Luis Ernesto
    El objetivo de este estudio fue determinar la validez y fiabilidad del instrumento de calidad percibida y satisfacción del servicio deportivo (EPOD2) en el contexto mexicano, así como invarianza de medición en función del sexo y de institutos del deporte. Participaron 1510 usuarios de servicios deportivos (Medad = 20.40, DT= 7.47). El valor de la medida de adecuación muestral del Análisis Factorial Exploratorio (AFE) fue óptimo, la prueba de Bartlett resultó estadísticamente significativa, por lo que el AFE es pertinente. El Análisis Factorial Confirmatorio (AFC) corroboró la estructura factorial de las escalas, el ajuste de los índices fue adecuado. La invarianza factorial indicó que la estructura es estable tanto para sexo como por instituto del deporte. Se concluye que el instrumento EPOD2 es válido y fiable para el estudio de la calidad percibida y satisfacción de servicios deportivos en población mexicana, además de ser un instrumento de fácil aplicación e interpretación

    Validity and reliability of an instrument to evaluate the digital competence of teachers in relation to online tutorials in the stages of Early Childhood Education and Primary Education
    (Universidad de Murcia, Servicio de Publicaciones, 2021) Guillén-Gámez, Francisco D.; Mayorga-Fernández, María J.; Contreras-Rosado, José A.
    This article demonstrates the validity and reliability of an instrument to evaluate the level of digital competence of Early Childhood Education and Primary Education teachers to carry out online tutorials using ICT resources as part of the educational process during the COVID-19 pandemic. The instrument consists of 35 items classified into five dimensions (A – functions of the tutor with the students; B – functions of the tutor with the teaching staff; C – functions of the tutor with the family; D – training in ICT and transfer; E – use of ICT resources). The instrument was applied to a sample of 1,098 active teachers from 14 autonomous communities located in Spain. Reliability was measured using Cronbach’s Alpha, the Spearman-Brown Coefficient, Guttman Two Halves, Omega McDonald, and for composite reliability. To check the validity of the instrument, we analysed the validity of understanding, and exploration of dimensionality using Factorial-Exploratory Analysis (EFA), and the instrument was adjusted for the different models through Confirmatory Factor Analysis (CFA). In addition, factorial invariance was evaluated based on the variables sex (male/female), type of centre (public/charter school), and type of teaching staff (Early Childhood Education/Primary Education), as well as external validity. The results of the reliability analyses were highly satisfactory and, in relation to the construct validity, the results found a good fit of the model, both in the internal validity and in the factorial invariance. The final version of the instrument consists of 25 items
