Psychopathology and response styles in the SCL-90 responses of acutely distressed persons

Using the responses of 197 suicidal and nonsuicidal patients of a crisis and short-term intervention unit, the item factor structure of the SCL-90 was examined. Results suggested a reduced dimensionality for the checklist rather than supporting the nine scales associated with the instrument's scoring key. The influence of various response styles on the SCL-90's dimensionality was also explored. Although a social desirability response style was strongly related to all SCL-90 subscales and factors, it did not offer a complete explanation for the checklist's apparent unidimensionality. Other explanations relating to methods of test construction and to patients' inability to differentiate symptoms were also preferred. Finally, although subscale scores may facilitate clinical interpretation, it was suggested that the SCL-90 might best be scored as a single index of general symptomatology.We wish to thank G. C.

Perspectives on international collaboration in sales research

Abstract

International research collaboration and co-authorship among scholars is always encouraged, yet it comes with its share of difficulties. While globalization brings its own challenges in sales, this special issue focuses on the challenges of fostering international collaboration in sales research. Such perspective is important in today’s academic context for three main reasons. First, international collaboration in research forces scholars to take an international perspective on research problems and thus consider fields of study that may transcend cultural boundaries. Second, with international research collaboration indubitably comes broader exchanges of ideas. Having a breadth of perspectives is at the very essence of scholastic work. Third, international research collaborations can drive intellectual communities to embrace important global challenges confronting modern sales organizations.     

我国关于实证主义与现代西方心理学研究的综述

实证主义问题是影响我国心理学全局发展的重大理论问题。文章从现代西方心理学的实证主义内涵、积极作用和消极影响等3个方面,对我国心理学界20余年有关实证主义的课题研究进行了系统地梳理和概括,并对该研究领域的未来发展谈了作者的几点认识和看法。     

发展性阅读障碍的理论及眼动研究

关于发展性阅读障碍,国外研究者,基于认知和生物因素,先后提出了语音缺陷论、小脑缺陷论、一般性大细胞功能障碍论等对发展性阅读障碍进行解释,并考察了患者的眼动特征,提出了有效的诊治方法。目前,汉语发展性阅读障碍研究主要局限在语音和正字法领域,也涉及局部脑区的功能缺陷,但还未从多角度测查其成因,如眼动。这里,在理论梳理的基础上,系统探讨了发展性阅读障碍者的眼动特征,如注视时间、注视次数、眼跳、回视等,及视觉加工的眼动机制     

The influence of just-world beliefs on driving anger and aggressive driving intentions

Decades of research demonstrate that the extent to which one believes the world is just can have important interpersonal consequences. Unfortunately, most of the commonly studied consequences are negative in nature. Guided by previous research demonstrating the buffering effect of just‐world beliefs and anger, the present research explores how belief in a just world (BJW) may mitigate anger in the domain of driving anger and examines the limiting conditions of this effect. Study 1 demonstrated the expected negative relation between common measures of BJW and anger expression in a driving context. Study 2 found that the buffering effects of just‐world beliefs and driver aggression were greater when BJW was violated (vs. not). Study 3 replicated the effects on aggression and anger and established a mediational role of anger on the buffering effects of just‐world beliefs on thoughts and driver aggression. Aggr.

Genetic and environmental influences on executive functions and intelligence in middle childhood

Executive functions (EFs) and intelligence (IQ) are phenotypically correlated. In twin studies, latent variables for EFs and IQ display moderate to high heritability estimates; however, they show variable genetic correlations in twin studies spanning childhood to middle age. We analyzed data from over 11,000 children (9- to 10-year-olds, including 749 twin pairs) in the Adolescent Brain Cognitive Development (ABCD) Study to examine the phenotypic and genetic relations between EFs and IQ in childhood. We identified two EF factors—Common EF and Updating-Specific—which were both related to IQ (rs = 0.64–0.81). Common EF and IQ were heritable (53%–67%), and their genetic correlation (rG = 0.86) was not significantly different than 1. These results suggest that EFs and IQ are phenotypically but not genetically separable in middle childhood, meaning that this phenotypic separability may be influenced by environmental factors.     

The Job Insecurity Scale: A psychometric evaluation across five European countries

Multiple instruments have been developed and used to measure quantitative job insecurity (i.e., insecurity to lose the job as such), often without systematic evaluation of their psychometric characteristics across countries and language barriers. This may hamper consistent and reliable cross-study and cross-country comparisons. This study's aim was to introduce and validate the four-item Job Insecurity Scale (JIS) developed by De Witte across five European countries (i.e., Belgium, The Netherlands, Spain, Sweden, and the UK). Overall, the results demonstrated the construct validity (i.e., configural invariance and invariance of the measurement model parameters), the reliability (internal consistency of the items), and the criterion validity (with respect to affective organizational commitment, perceived general health, and self-reported performance) of the JIS. The different translations of the JIS can thus be considered as valid and reliable instruments to measure job insecurity and can be used to make meaningful comparisons across countries. Furthermore, the JIS translations may be utilized to assess how job insecurity is related to outcomes.     

Hacia una estructuración teórica de la Psicología Diferencial

RESUMEN

Los autores enmarcan en sus coordenadas temporales y teóricas la obra de Royce y Powell, analizando en profundidad sus implicaciones. Consideran que el análisis estadístico multivariado, especialmente factorial, que la psicología diferencial ha adoptado desde hace algunos años resulta particularmente adecuado a la hora de desglosar inductivamente los contenidos y datos de la realidad. Sugieren que Royce y Powell presentan la esencia del nuevo enfoque, recogiendo aportaciones de la Teoría de la Información y de la Teoría General de Sistemas. Destacan, entre otras cuestiones, que la Teoría multifactorial-sistemática incluya el concepto de tipo, enfatice tanto las derivaciones cognitivas como afectivas y posibilite una evaluación comprehensiva de la persona en función de los perfiles en cada uno de los subsistemas. Sin embargo, encuentran susceptible de discusión el recurrir a un modelo jerárquico para estructurar el supra-sistema (la personalidad) y cada sub-sistema. Los autores consideran que la psicología diferencial, a través de estructuraciones como la de Royce y Powell, muestra que la validez ecológica nunca ha estado al margen de sus objetivos y presupuestos, y terminan afirmando que esta disciplina sintoniza con los nuevos paradigmas en psicología fiel a sus métodos y herramientas, pero abierta a desafíos tanto teóricos como empíricos.     

Indicadores aislados versus patrón general expresivo en la detección de la mentira

Resumen

Frente a planteamientos teóricos clásicos, en relación con el fenómeno de la detección de la mentira, que postulan que la existencia de indicadores no verbales aislados facilitan el reconocimiento de mensajes falsos, este trabajo plantea la existencia de un patrón general de configuración que varía cualitativamente para mensajes verdaderos y falsos. Las condiciones experimentales ideadas para este trabajo (presentación de mensajes falsos, precedidos o no de mensajes verdaderos) permitieron a los sujetos experimentales contrastar las diferencias entre estos patrones, facilitando el reconocimiento de mensajes fraudulentos, siendo las mujeres las que mejor aprovecharon las condiciones facilitadoras.     

Reinterpretación atencional,con base empírica,del factor general de inteligencia

Resumen

En este trabajo se propone la reconceptualizaáón del factor general de inteligencia en fundón de la capacidad atencional de uso general. Partiendo de un experimento anterior en el que se apoya la existencia de la capacidad de procesamiento de uso general, se elabora un diseño que pretende demostrar que ésta es el soporte de la formación del factor G. A su vez, se pone de relieve el interés de usar la correlación en conjunción con determinados tipos de manipulación experimental de la tarea o de la interacción sujeto-tarea, para la investigación de las capacidades de procesamiento comprometidas en las tareas.
