Psychosocial risk assessment among families receiving assistance from the social services

This study analyses the psychosocial risk profiles that better discriminate between three levels of risk: low, middle and high. We also examine to what extent the assessments of the level of risk made by professionals of social services are consistent with their decision of initiate a "risk declaration" expedient. For this purpose, 468 cases of families (245 two-parents and 223 one-parent) were examined through the Psychosocial Risk Profile of the Family. Discriminant analysis showed that social exclusion and family violence profiles discriminate between high and middle-low levels of risk in two-parent families. Negligence and family violence plus maternal inadequacy and children maladjustment discriminate between high and middle-low levels of risk in one-parent families. There is a high consistence between the assessment of psychosocial risk and the decision to initate a procedure of a "risk declaration" in both families, with a tendency to overestimate the middle risk in one-parent families.     

A Latent Class Multidimensional Scaling Model for Two-Way One-Mode Continuous Rating Dissimilarity Data

In this paper, we propose a cluster-MDS model for two-way one-mode continuous rating dissimilarity data. The model aims at partitioning the objects into classes and simultaneously representing the cluster centers in a low-dimensional space. Under the normal distribution assumption, a latent class model is developed in terms of the set of dissimilarities in a maximum likelihood framework. In each iteration, the probability that a dissimilarity belongs to each of the blocks conforming to a partition of the original dissimilarity matrix, and the rest of parameters, are estimated in a simulated annealing based algorithm. A model selection strategy is used to test the number of latent classes and the dimensionality of the problem. Both simulated and classical dissimilarity data are analyzed to illustrate the model.

Q-Coh: A tool to screen the methodological quality of cohort studies in systematic reviews and meta-analyses

The evaluation of the methodological quality of primary studies in a systematic review is a key process to enhance the likelihood of achieving valid results. When considering non-randomized designs as cohort studies, this process becomes even more critical, since these designs are more susceptible to bias than randomized controlled trials are. Taking this into account, a tool, named Q-Coh, was designed with the aim to screen the methodological quality of the primary studies with a cohort design priming specificity over sensitivity in a reasonable application time. After applying it to 21 prospective cohort studies by three raters, all domains had a moderate to good agreement, with all except one of them having statistically significant kappa values. Despite there is no gold standard for the methodological quality, arguments supporting its validity are given. Future research should assess the psychometric properties of Q-Coh in the context of real meta-analyses, evaluate the influence of the raters’ substantive and methodological expertise on these properties, and explore different ways of including the domains-based ratings of the quality provided by Q-Coh into meta-analyses.     

Updating spatial layouts mediated by pointing and labelling under physical and imaginary rotation

The present experiments manipulated the modality in which participants communicated object directions (by pointing or verbal labelling) in a learned layout, and the mode in which they were required to rotate (physically or imaginary). The results showed that the pointing modality was strongly influenced by the mode of rotation (Experiment 1). Pointing was faster and more accurate in the physical than in the imaginary rotation. In addition, a different pattern of dimension accessibility was observed: equi-accessibility in physical rotation (front-back = right-left) and standard in imaginary rotation (front-back < right-left). By contrast, the verbal modality was less influenced by the mode of rotation. The same standard pattern of dimension accessibility and similar speed was obtained in physical and imaginary rotation. These results are explained by proposing a first-order embodiment, typical of ordinary pointing, which involves a low-cost sensory-motor updating of object positions and a second-order embodiment, most typical of language, which involves a represented (rather than physical) self and an object-to-frame high-cost updating.     

Assessment of a sexual coercion prevention program for adolescents

This study's focus is to evaluate a sexual coercion prevention program in adolescents. Using a before-and-after design with both a treatment group (n = 93) and a control group (n = 76), an intervention of seven sessions was completed. Said sessions included such content as conceptualizing sexual freedom, sexual coercion and voluntary consent, analyzing different sexual coercion tactics and the contexts in which they occur, empathy toward the victim, and developing abilities to avoid risky situations. Other risk factors for coercive behavior and sexual victimization are explored as well, such as alcohol use, sexist attitudes and inadequate communication, among others. The intervention's results include a decrease in stereotypical beliefs about the opposite sex and increased empathy toward victims of sexual coercion. These changes were maintained with the passage of time. Also, in the treatment group, a more acute decline was observed in the proportion of young people engaging in sexually coercive behaviors, This article emphasizes the importance, necessity and efficacy of such interventions, and discusses and analyzes possible improvements to the program for its future implementation.
