Factors associated with eating behavior in pre-adolescents

The goals of this study are the preliminary Spanish adaptation and validation of the following questionnaires: the Children's Eating Attitudes Test (ChEAT), the Lawrence Self-Esteem Questionnaire (LAWSEQ) and the Body Esteem Scale (BES). In addition, we studied bodily self-esteem in pre-adolescent children, and their possible relation to certain eating attitudes and general self-esteem. This study is cross-sectional, analytical and observational. The sample was made up of 457 participants, 55.14% boys and 44.86% girls aged between 8 and 12 (M = 10.14, SD = 1.30). A multivariate analysis of variance (Age x Sex) was carried out with the total scores of LAWSEQ, ChEAT, BES, BIA and BMI. Cronbach's alpha reliability coefficient was .76, .80, and .67 for ChEAT, BES, and LAWSEQ, respectively. The boys presented significantly higher total scores in the ChEAT than the girls. Of the sample, 10.4% (n = 45) scored over the cut-off point of the ChEAT: These subjects presented lower general and bodily self-esteem, a slimmer ideal image and a greater discrepancy between their real self and their social self.     

Validation scheme and procedures to analyze consequential validity

The argument-based validation scheme guides assessment of the consequences of testing. The distinction between semantic inference and political inference allows us to combine the validation of the consequences in a single validation scheme. The validation process should produce evidence about the assumptions that support both types of inference. After presenting the validation scheme, we provide examples of its use in the assessment of the testing of two applications: the use of high-stake tests in educational contexts and the validation of adjustments made in standardized tests for people with disabilities. Finally, we propose procedures for the validation of consequences and we discuss the suitability of the argument-based validation scheme for the validation of the consequences of testing in Spain.     

Scene-Based Psychodramatic Family Therapy With Troubled Adolescents and Parents: A Pilot Study

Scene-Based Psychodramatic Family Therapy (SB-PFT) is an innovative treatment used with troubled adolescents and their parents to improve family relationships and reduce adolescents’ problematic behavior. It integrates the principles of family therapy, psychodrama, and multiple-family group methodology. This research is a pilot study to obtain empirical evidence on the SB-PFT therapeutic process by gauging the perception of change of troubled adolescents and their parents, and assess the perceived helpfulness of its methodology and techniques. Ten multiple-family intervention groups were drawn up, with 110 participants (63 adolescents and 47 parents), and we adopted a qualitative methodology with focus groups, using an inductive analysis of 290 active constructions of participant narratives. Concerning perception of change, the adolescents reported mainly gaining in social support, prosocial attitudes, keys to problem solving, and expression of emotions due to the treatment. The parents perceived improvement in social support, keys for educational practices, emotional well-being, and expression of emotions due to the treatment. Regarding the perceived helpfulness of methodology and techniques, both adolescents and parents highlighted the usefulness of the group methodology for gaining social support, relativizing the problem, and expressing emotions. Additionally, participants referred to role-playing and mirror techniques as the most useful techniques. In conclusion, this first study on SB-PFT presents and describes its treatment for troubled adolescents and their parents. The participants’ positive perception of their personal and relational change after treatment should serve to promote further studies with quantitative methodology in order to verify the effectiveness of SB-PFT treatment.     

Use of multilevel logistic regression to identify the causes of differential item functioning

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups.     

Prediction of Burnout in Volunteers

This work studies the personal experience of volunteering and several antecedent and consequent variables. We studied the effect of the amount of time dedicated to the organization, motivation, social support, integration in the organization, self‐efficacy, and characteristics of the work on a consequent variable of the volunteering experience; that is, burnout, with its 3 components of efficacy, cynicism, and exhaustion. The statistical analysis shows that the time dedicated to volunteering and the extrinsic motivations (i.e., social and career) predicts higher levels of burnout, whereas intrinsic motivations (i.e., values and understanding), life satisfaction, and integration in the organization are negatively related to burnout.     

Expectations of efficacy,social influence and age as predictors of helmet-use in a sample of Spanish adolescents

Despite the proven effectiveness of helmets in avoiding or reducing the severity of brain injuries and the law requiring their compulsory use, both by drivers and passengers of motorcycles, approximately 20% of Spanish adolescent motorcycle users do not wear them. This study analysed the pattern of motorcycle and helmet-use in a sample of Spanish adolescents (age range 14–17; n = 874) and the relationship this safety measure has with belief in its effectiveness and its use by friends and relatives. Overall more males than females ride motorcycles and this difference increased with age. Motorcycle drivers and passengers who always wear helmets consider them to be more effective than those who do not use a helmet all of the time. The best predictors of helmet-use among motorcycle drivers were their beliefs regarding the helmet-use of their friends and relatives. In the case of passengers, knowing that their friends always wear them and age were the best predictors of helmet-use. Programmes and campaigns promoting helmet-use must take into account the modelling effect of close referents or other role models in order to increase their effectiveness.     

Rationality and Value: The Epistemological Role of Indeterminate and Agent-dependent Values

An important trend in contemporary epistemology centers on elaborating an old idea of pragmatist pedigree: theory selection (and in general the process of changing view and fixing beliefs) presupposes epistemic values. This article focuses on analyzing the case where epistemic values are indeterminate or when the sources of valuation are multiple (epistemic values like coherence and simplicity need not order options in compatible ways). According to the theory that thus arises epistemic alternatives need not be fully ordered by an underlying notion of information-value and therefore the usual economic techniques of optimization cannot be applied in order to compute optimal contractions. But in cases of this sort it is still rational to maximize, i.e. to deem an option as choosable when it is not known to be worse that any other. We present here basic results about a notion of liberal contraction based on maximizing quasi-orderings. This requires the previous solution of some open problems in the theory of rational choice functions, namely a full characterization of choice functions rationalizable in terms of maximization of quasi-transitive relations. We conclude by discussing the problem of what is the adequate feasible set for calculating maximizing solutions for contraction problems and by considering the epistemological roots of some counterexamples against the most fundamental axioms on choice functions (like α). While the first part of the paper shows how economic insights can be used to improve our understanding of the principles of belief formation and change, this final section reverses this strategy by showing the utility of epistemological insights and techniques for providing invariance conditions capable of regulating the applicability of the pure principles of choice.     

Non-Adjunctive Inference and Classical Modalities

The article focuses on representing different forms of non-adjunctive inference as sub-Kripkean systems of classical modal logic, where the inference from □A and □B to □A∧B fails. In particular we prove a completeness result showing that the modal system that Schotch and Jennings derive from a form of non-adjunctive inference in (Schotch and Jennings, 1980) is a classical system strictly stronger than EMN and weaker than K (following the notation for classical modalities presented in Chellas, 1980). The unified semantical characterization in terms of neighborhoods permits comparisons between different forms of non-adjunctive inference. For example, we show that the non-adjunctive logic proposed in (Schotch and Jennings, 1980) is not adequate in general for representing the logic of high probability operators. An alternative interpretation of the forcing relation of Schotch and Jennings is derived from the proposed unified semantics and utilized in order to propose a more fine-grained measure of epistemic coherence than the one presented in (Schotch and Jennings, 1980). Finally we propose a syntactic translation of the purely implicative part of Jaśkowski's system D₂ into a classical system preserving all the theorems (and non-theorems) explicilty mentioned in (Jaśkowski, 1969). The translation method can be used in order to develop epistemic semantics for a larger class of non-adjunctive (discursive) logics than the ones historically investigated by Jaśkowski.
