Examining the structure of ideas of reference in clinical and community samples

Aims: This study addresses the psychometric properties of a Spanish validation of the REF scale of ideas of reference (IRs) in detecting and following at-risk mental states and psychosis. Methods: A total of 9447 participants were distributed in three groups: 676 patients with various diagnoses-154 with psychotic disorders, 6291 youths aged 11 to 20, and 2480 adult participants aged 21 to 84. Results: Youths had higher scores than adults on IRs, observing a progressive decrease and stabilization in the twenties. Exploratory factor analysis provided a structure for the overall IRs score, with five first-order dimensions and one second-order dimension. Confirmatory factor analysis supported the structure with excellent fit. The REF scale was invariant across sex and samples. The internal consistency of the complete scale was excellent and acceptable across the five first-order factors. Strong relationships were found with the positive dimension of the community assessment of psychic experience-42, as well as with aberrant salience. Low and moderate relationships were found with public self-consciousness, anxiety, and depression. Youths and patients diagnosed with schizophrenia and other psychotic disorders had a high mean IRs frequency. Male sex, greater age (among the adults), and the "causal explanations", "Songs, newspapers, books" and laughing and commenting" REF subscales showed predictive power in the diagnostic categories of schizophrenia and other psychotic disorders

Vulnerability to Psychosis, Ideas of Reference and Evaluation with an Implicit Test

Background: Ideas of reference (IRs) are observed in the general population on the continuum of the psychotic phenotype (as a type of psychotic-like experiences, PLE). The instruments usually used to evaluate IRs show some problems: They depend on the cooperation of the participant, comprehension of items, social desirability, etc. Aims: The Testal emotional counting Stroop (TECS) was developed for the purpose of improving evaluation of individuals vulnerable to psychosis and its relationship with ideas of reference. The TECS (two versions) was applied as an implicit evaluation instrument for IRs and related processes for early identification of persons vulnerable to psychosis and to test the possible influence of emotional symptomatology. Method: A total of 160 participants (67.5% women) from the general population were selected (Mean (M) = 24.12 years, standard deviation (SD) = 5.28), 48 vulnerable and 112 non-vulnerable. Results: Vulnerability to psychosis was related to greater latency in response to referential stimuli. Version 4 of the TECS showed a slight advantage in identifying more latency in response to referential stimuli among participants with vulnerability to psychosis (Cohen's d = 1.08). Emotional symptomatology (especially stress), and IQ (premorbid) mediated the relationship between vulnerability and IR response latency. Conclusions: The application of the implicit Testal emotional counting Stroop test (TECS) is useful for evaluating processes related to vulnerability to psychosis, as demonstrated by the increased latency of response to referential stimuli

Sprint performance and mechanical outputs computed with an iPhone app: Comparison with existing reference methods

The purpose of this study was to assess validity and reliability of sprint performance outcomes measured with an iPhone application (named: MySprint) and existing field methods (i.e. timing photocells and radar gun). To do this, 12 highly trained male sprinters performed 6 maximal 40-m sprints during a single session which were simultaneously timed using 7 pairs of timing photocells, a radar gun and a newly developed iPhone app based on high-speed video recording. Several split times as well as mechanical outputs computed from the model proposed by Samozino et al. [(2015). A simple method for measuring power, force, velocity properties, and mechanical effectiveness in sprint running. Scandinavian Journal of Medicine & Science in Sports. https://doi-org.ezproxy.universidadeuropea.es/10.1111/sms.12490] were then measured by each system, and values were compared for validity and reliability purposes. First, there was an almost perfect correlation between the values of time for each split of the 40-m sprint measured with MySprint and the timing photocells (r = 0.989–0.999, standard error of estimate = 0.007–0.015 s, intraclass correlation coefficient (ICC) = 1.0). Second, almost perfect associations were observed for the maximal theoretical horizontal force (F0), the maximal theoretical velocity (V0), the maximal power (Pmax) and the mechanical effectiveness (DRF–decrease in the ratio of force over acceleration) measured with the app and the radar gun (r = 0.974–0.999, ICC = 0.987–1.00). Finally, when analysing the performance outputs of the six different sprints of each athlete, almost identical levels of reliability were observed as revealed by the coefficient of variation (MySprint: CV = 0.027–0.14%; reference systems: CV = 0.028–0.11%). Results on the present study showed that sprint performance can be evaluated in a valid and reliable way using a novel iPhone app.Sin financiación2.576 JCR (2017) Q2, 22/81 Sport Sciences1.122 SJR (2017) Q1, 480/2878 Medicine (miscellaneous), 44/285 Orthopedics and Sports Medicine, 24/201 Physical Therapy, Sports Therapy and Rehabilitation; Q2, 34/127 Sports ScienceNo data IDR 2017UE

Small Towns, una realidad urbana en la Hispania romana (II)

Congreso Internacional MARQ Museo Arqueológico de Alicante: 26-28 de Octubre de 2021.Las ciudades pequeñas/Small Towns de la Península Ibérica son la abrumadora mayoría de las aproximadamente 400 ciudades que en época romana existieron en Hispania, es decir casi una quinta parte de las aprox. 2000 ciudades del Imperio Romano entero. De ahí que resulta de interés como punto de partida y base de estudio para la investigación, a pesar de las dificultades de definición. Mientras que los intentos anteriores buscaban utilizar el término en su calidad de clasificador para poder elaborar una jerarquía de asentamientos, y así asignar a cada uno de ellos su lugar en la clasificación y de esa manera describir sus propiedades correspondientes, aqui se propone la utilización del término Small Towns solo en su calidad de aspecto diferenciador con vistas a las capitales de provincia y de conventus, manteniendo toda su imprecisión para asentamientos con o sin trama urbana extendida, en un sentido amplio y genérico sin condicionantes ni jurídicos ni políticos. Las Small Towns suelen y pueden tener, con alguna variedad, características urbanas como edificios sacros y públicos, una muralla defensiva y casas urbanas. Sin embargo, suele observarse una desproporción entre la edificación pública y sacra por un lado y la privada por el otro en el sentido, de que la primera tenga una clara predominancia sobre la segunda tanto en calidad como en cantidad. Por otro lado les suelen faltar a las Small Towns otros criterios importantes habituales de los centros mayores como son la alta densidad de población, altos estándares de calidad, un cierto grado de diversificación económica, un plan urbanístico de circulación. Esas características ausentes son compensadas, por el otro lado, con un elemento del que se nutre a través de la carga generada por la (excesiva) edificación sacra y pública, y que le proporciona aquel atributo, que resume en sí la esencia de los centros mayores, que es la más típica y la que más los destaca: un exceso de significado.Esta publicación ha sido posible gracias a la financiación de la subvención global de la Junta de Extremadura, a través de la Consejería de Ciencia, Economía y Agenda Digital al Instituto de Arqueología de Mérida (Referencia 20164499).Peer reviewe
