Social network addiction in young people has been extensively studied and associated with multiple factors. Among the scales designed to measure this, the 24-item version of the Social Network Addiction Questionnaire (SNAQ) is one of the most widely used. This study analyses the psychometric properties of the Spanish version adapted to undergraduates. The content and construct validity of the scale was explored using the Rasch model and a confirmatory factor analysis. The data categorisation structure, construct dimensionality, model fit, subject and item reliability, Wright Map structure, and differential item functioning (DIF) were specifically analysed. 1,809 students from 24 Spanish universities participated. The results indicate that the SNAQ presents good reliability and dimensionality, and a good model fit; however, elements in need of improvement are appreciated mainly in the proposed Likert scale, in the development of new items that measure the extremes of addiction to social network sites and in the wording of one item. With respect to factor analysis, three factors were obtained thatcoincide with the original construct. With the improvements that have been observed through validation, the questionnaire could confidently be used to measure the construct in the university population. The instrument fills an important gap in the identification of addictive behaviours in the use of social networks, which could lead to a subsequent intervention involving undergraduates.
Physical examination is essential in diagnosing tendinous lesions. This is particularly true of the flexor digitorum superficialis of the little finger (FDS5), which is functionally absent in approximately 30% of the population. The objective of our study was to determine the diagnostic value of 3 clinical tests commonly used to assess the function of this tendon. Methods Patients with wounds of the FDS5 were included in this study. Under local or regional anesthesia, 3 described clinical tests were performed to assess the function of the FDS5: (i) the classic test; (ii) Stein's modified test, and (iii) Mecott's modified test. We determined sensitivity, specificity, and predictive values of all such tests. The integrity of the tendon was assessed surgically. Correlation among blinded observers was also established. Results A total of 28 subjects with a mean age of 28 years (ranging from 5 to 56) participated in this study. The classic test obtained a sensitivity of 100% and a specificity of 72%; Stein's test resulted in a sensitivity of 83% and a specificity of 95%, whereas Mecott's test reached a sensitivity of 100% and a specificity of 95%. Conclusions Among the 3 tests described and used in our study, Mecott's modified test proved to be more sensitive and specific than the other two; therefore, we consider this to be the test that should be used in determining the integrity of the FDS5.
El estrés laboral y el burnout son enfermedades psicosociales que influyen negativamente en la salud. Una de las variables que puede estar relacionada con el estrés laboral es el género. Precisamente, este trabajo presenta un análisis para determinar en qué medida las profesoras universitarias manifiestan mayor nivel de estrés en el ámbito laboral. A través de una metodología cuantitativa no experimental se implementó un cuestionario construido ad hoc. El instrumento contiene treinta ítems estructurados en cinco subdimensiones (estrés de rol, estrés en profesores universitarios, agotamiento emocional, despersonalización y falta de realización personal). Se realizaron análisis estadísticos descriptivos, inferenciales, de fiabilidad y validez de la escala y se utilizó la Teoría de la Medición de Rasch (TMR) para el análisis de perfiles. Los resultados revelan la presencia de niveles moderados de estrés en 564 docentes universitarios, principalmente, relacionado con tareas específicas del ámbito laboral. Además, se confirmó que las mujeres en sus primeros años de desarrollo profesional, con una elevada carga docente y sin cargos de responsabilidad en la gestión universitaria son quienes tienden a experimentar mayor grado de estrés. Estos resultados justifican la necesidad de atender a factores psicosociales y la gestión del estrés que afectan al profesorado desde una vertiente social, psicológica y educativa para el afrontamiento correcto de sus funciones.
