The Children's Social Vulnerability Questionnaire (CSVQ): Validation,relationship with psychosocial functioning,and age-related differences

Background/Objective: Social vulnerability refers to difficulties detecting potentially harmful interpersonal situations. Although it is an important predictor of psychosocial and interpersonal difficulties in clinical samples, research investigating this construct is scarce. We aimed to (a) develop a brief measure for assessing social vulnerability in typically developing children, the Children's Social Vulnerability Questionnaire (CSVQ) (b) examine the relationship between social vulnerability and psychosocial functioning, (c) explore age-related differences, and (d) explore levels of social vulnerability amongst children with clinical needs. Method: Data were gathered on two samples. Participants were parents (n = 790) of elementary school-aged children (3-12 years), and parents and teachers of a second sample (n = 96). Results: Results provide strong reliability and validity evidence. Social vulnerability showed moderate relationships with emotional and behavioural problems, and only a weak relationship with social skills. Parents perceived greater social vulnerability in younger than older children, and amongst children with clinical needs. Parents’ and teachers’ scores were correlated. Conclusions: Social vulnerability is not simply a lack of social skill; rather, it is a valuable construct for understanding psychosocial risk, especially for young and clinical samples of children.

Factors Affecting Censorship by Canadian Librarians

This study investigated the risk propensity and self-actualization of public librarians with regard to censorship behavior. A sample of 169 librarians from the province of Ontario responded to a 124-item mail questionnaire that incorporated a number of previously validated instruments, including the Adorno F Scale (Adorno, Frenkel-Brunswick, Levinson, & Sanford, 1950), the Short Index of Self-Actualization (Jones & Crandall, 1986), and the Choice Dilemmas Questionnaire (Kogan & Wallach, 1964). Analyses indicated that the librarians were generally liberal in attitude but conservative in behavior with respect to censorship and book selection. Moreover, they appear to have been averse to taking risks and not selfactualized. These results are discussed in terms of cognitive dissonance theory and risk propensity theory.     

Factores psicosociales y cáncer: una revisión crítica

Resumen

Se presenta en este artículo una introducción al campo de estudio de las relaciones entre factores psicosociales y neoplasia, enmarcándolo dentro de la medicina conductual y desde un enfoque interdisciplinar. A continuación se discute el papel que pueden desempeñar las variables psicosociales (estrés) en la vulnerabilidad del ser humano a la enfermedad en general a través de su acción sobre el sistema inmune. En el apartado III se realiza una revisión crítica en la investigación en la que se ha intentado delimitar la influencia de factores psicosociales en la aparición y pronóstico del cáncer, en animales (cáncer experimental) y en el ser humano. Se discute por último el papel de los mediadores biológicos propuestos como más importantes hasta el momento en la literatura del área (sistemas neuroendocrino e inmune). De esta revisión se desprende que los resultados de la investigación, aunque su- gerentes no son definitivos, ni tampoco están claros los mecanismos biológicos a través de los cuales se puede producir la influencia. Después de analizar algunas de las deficiencias metodológicas más importantes de los trabajos realizados, creemos que en enfoque más adecuado para poner a prueba la hipótesis de que los factores psicosociales afectan al desarrollo del cáncer debería ser longitudinal, utilizando grandes muestras y estudiando variables psicosociales y biomédicas conjuntamente.     

Los efectos placebo en la psicología experimental y clínica

RESUMEN

Este trabajo comienza planteando que el término “placebo” se ha convertido en un cajón de sastre en el que los autores engloban diferentes, y a menudo opuestas y dispares, concepciones. Después de destacar la atención creciente a los efectos placebo en la psicología actual y la tendencia a la convergencia entre distintos enfoques en psicoterapia, la autora aborda las divergencias y dificultades para definir placebo aludiendo a concepciones de diferentes autores y centrándose en el planteamiento de Grünbaum (1985). Avia coincide con Brody (1985) en que el problema de nuestro desconocimiento sobre qué sea placebo afecta, recíprocamente, a nuestra falta de conocimiento sobre lo que debe considerarse terapia, ofreciendo algunas reflexiones en torno a posibles explicaciones de este fenómeno y destacando la débil frontera que separa éstas de las explicaciones sobre ciertas variables cognitivas. La autora concluye la presentación de este dossier afirmando que será a partir de la elaboración teórica y el trabajo de investigación como podremos profundizar en el conocimiento del fenómeno placebo.     

The instrumental use of group prototypicality judgments

Recently, Waldzus et al. [Waldzus, S., Mummendey, A., Wenzel, M., & Boettcher, F. (2004). Of bikers, teachers and Germans: Groups’ diverging views about their prototypicality. British Journal of Social Psychology, 43, 385-400] have shown that ingroup members often tend to judge the ingroup as more prototypical of the superordinate group than other subgroups. In this paper, we argue that, in addition to the motivational processes that have been posited to explain this phenomenon, prototypicality judgments may vary according to instrumental considerations. In particular, those who believe their ingroup interest to be undermined by remaining part of the common group will downplay ingroup’s prototypicality as a way to sustain their separatist position. In a first study (N = 63), we found that Scottish respondents who support Scottish independence judged the Scots to be less prototypical of Britain than the English, as compared with Scots who do not support independence. In a second study (N = 191), we manipulated the rhetorical context within which prototypicality judgments were made. Results showed that the pattern found in study 1 only applied when the issue of independence was made salient. When the issue of the importance of Scottish history in Britain was made salient, the opposite pattern appeared, i.e. supporters of independence judged the Scots more prototypical than the English compared to non-supporters. These results were also interpreted in instrumental terms.     

Accounting for sensation seeking in route choice behavior with travel time information

The purpose of this paper is to demonstrate that latent variables, with the focus on sensation seeking concepts, incorporated in new technique of route choice modeling, improve our analyzing of route choice behavior with pre-trip travel time information. The application of a hybrid discrete choice model framework integrates a latent variable model and a route choice model by combining their measurement and structural equations. The model is estimated based on data from a laboratory experiment and a field study of a simple network. The results show that certain sensation seeking domains (e.g., thrill and adventure seeking) alongside traditional variables (e.g., travel time information) enrich our understanding and provide more insight into route choice behavior. Furthermore, observed personal variables, such as gender and marital status, may serve as causal indicators to sensation seeking variables.     

TREATMENT INTEGRITY IN APPLIED BEHAVIOR ANALYSIS WITH CHILDREN

Functional analysis of behavior depends upon accurate measurement of both independent and dependent variables. Quantifiable and controllable operations that demonstrate these functional relationships are necessary for a science of human behavior. Failure to implement independent variables with integrity threatens the internal and external validity of experiments. A review of all applied behavior analysis studies with children as subjects that have been published in the Journal of Applied Behavior Analysis between 1980 and 1990 found that approximately 16% of these studies measured the accuracy of independent variable implementation. Two thirds of these studies did not operationally define the components of the independent variable. Specific recommendations for improving the accuracy of independent variable implementation and for defining independent variables are discussed.     

Maladaptive personality traits in adolescence: Psychometric properties of the Personality Diagnostic Questionnaire-4+

The Personality Diagnostic Questionnaire-4+ (PDQ-4+) is a self-report used for the assessment of personality disorder traits, however, its psychometric characteristics have yet to be tested in community samples of adolescents. The main goal was to analyze the psychometric properties of the PDQ-4+ scores in a large sample of non-clinical adolescents (N = 1,443; M = 15.9 years; SD = 1.2). The PDQ-4+ scores showed adequate psychometric properties. Reliability of the subscales, incorporating a Likert-type 5-point response format, ranged from .62 to .85. The study of the internal structure at item level revealed that the PDQ-4+ subscales were essentially one-dimensional. Analysis of the internal structure at the subscale level by means of exploratory factor analysis and exploratory structural equation modeling yielded a possible three-dimensional solution. The PDQ-4+ subscales correlated moderately with emotional and behavioural variables measured by the Strengths and Difficulties Questionnaire. The results have clear implications for the understanding of maladaptive personality traits in adolescents.     

Procedural Text Structure and Reader Perceptions and Performance

This research tested the relationship between text structural variables (on vs. off the causal chain, active vs. static information, and hierarchical structure) and reader perceptions, reading time, and true-false performance for procedural texts. Twenty-four college-age participants each read 3 procedural texts. As predicted, sentences that were (a) on the causal chain, (b) active, and (c) associated with task steps were read more slowly and judged to be more important (p < .05). The results were similar to those previously found with narratives, except for the hierarchical structure variable. Also as predicted, text differences were found such that as the variation in the type of information contained in the text increased, relationships with the structural variables increased.
