Spanish Adaptation and Validation of the Outcome Questionnaire OQ-30.2
2017
This study assessed the psychometric properties of a Spanish version of the Shortened Outcome Questionnaire (OQ-30.2, Lambert et al., 2004) validated with a sample of 546 patients in an outpatient mental health clinic and 100 non-clinical adults in Chile. Our results show that this measure has similar normative data to the original measure, with a cutoff score for the Chilean population set at 43.36, and the reliable change index at 14. This Spanish OQ-30.2 has good internal consistency (α = 0.90), has concurrent validity with the Depressive, Anxious, and Somatoform disorders measuring scale (Alvarado and Vera, 1991), and is sensitive to change during psychotherapy. Consistent with previous…
Development and Validation of the Test of Orthorexia Nervosa (TON-17)
2021
This study aims to develop and validate a new self-report questionnaire to measure orthorexia nervosa (ON). Based on a current review of the scientific literature and interviews with people at risk of orthorexia, 40 items were selected to test orthorexia nervosa (TON-40). A total sample of 767 individuals (M = 26.49, SD = 9.66, 56.98% women) participated in the study. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and composite construct analysis (CCA) were performed to find an appropriate model of sufficient reliability and validity and stable construction. Convergent validation was performed regarding the correlation of the TON-17 with another measure of ON (OR…
Validation of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents
2021
Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of signifi…
El fenómeno del sexting entre los adolescentes españoles: prevalencia, actitudes, motivaciones y variables explicativas
2020
El sexting es un fenómeno que consiste en el envío y la recepción de fotos, videos y/o mensajes de texto de naturaleza sexual a través de smartphones. Como en todos los demás países desarrollados, se está convirtiendo en una práctica cada vez más popular entre los adolescentes de España. Al tratarse de un fenómeno muy reciente todavía no existen muchos trabajos que hayan estudiado con profundidad su entidad y sus factores implicados. Por tanto, los dos objetivos de este estudio fueron determinar la prevalencia y analizar las variables explicativas del inicio y del mantenimiento de las conductas de sexting. La muestra estuvo formada por 784 adolescentes españoles (52% chicos y 48% chicas) co…
La satisfacción sexual en parejas con estilos de apego seguro y ansioso
2018
Debido a la fuerte vinculación entre la satisfacción sexual, de pareja y el apego de ambos miembros de la diada, el objetivo de esta investigación fue examinar la satisfacción de pareja y sexual en las diferentes combinaciones de estilos de apego. Para ello se analizó la satisfacción sexual y de pareja en los diferentes estilos de apego de cada participante y de su pareja. En el estudio participaron 86 parejas heterosexuales, con edades entre los 20 y 60 años. Los resultados muestran que las personas seguras tienen una mayor satisfacción sexual y de pareja. Las diadas constituidas por un hombre seguro y una mujer segura son las que más satisfechas están, las mujeres seguras están menos sati…

The role of executive function in social competence and behavioural problems in childhood education
2018
Diversos estudios han encontrado una relación entre la función ejecutiva, los problemas de conducta y la competencia social. Sin embargo, hasta este momento, pocos estudios han investigado el papel de los distintos componentes de la función ejecutiva en la competencia social, o en los problemas de comportamiento más frecuentes en la educación infantil. Por esta razón, el objetivo principal de este artículo es evaluar la relación de las funciones ejecutivas con los problemas de conducta y la competencia social en la infancia. El estudio incluyó 260 estudiantes, de 5 años. Los resultados del análisis de ruta demostraron que todos los componentes de las funciones ejecutivas predicen, al menos,…
Multiple job holding, societal change, and individual careers: Contributions to the chaos theory of careers
2020
The chaos theory of careers was applied to identify the connections between multiple jobholders’ careers and societal change. Multiple job holding is a form of employment that consists of two or more overlapping jobs. Six interviews with men born in the 1960s in Finnish North Karelia, whose multiple job holding included agricultural and forestry work, were analyzed. Our results showed that multiple job holding career development has societal connections and that the experiences of multiple job holding varied across individuals. Moreover, multiple job holding experiences and further career development endeavors were influenced by whether the multiple job holding career developed in line wit…

What represents a face? A computational approach for the integration of physiological and psychological data.
1997
Empirical studies of face recognition suggest that faces might be stored in memory by means of a few canonical representations. The nature of these canonical representations is, however, unclear. Although psychological data show a three-quarter-view advantage, physiological studies suggest profile and frontal views are stored in memory. A computational approach to reconcile these findings is proposed. The pattern of results obtained when different views, or combinations of views, are used as the internal representation of a two-stage identification network consisting of an autoassociative memory followed by a radial-basis-function network are compared. Results show that (i) a frontal and a…
