Psychosocial risk factors at work as predictors of mobbing

This work analyses the way in which various psychosocial risk indicators may predict mobbing. A sample of 638 workers, 168 men and 470 women, from the fruit-and-vegetable sector was evaluated. An anonymous questionnaire was administered to all employees who were present on the evaluation days in the companies comprising the study. After analysing the data obtained with the mobbing questionnaire NAQ-RE (Sáez, García-Izquierdo, and Llor, 2003) and with the psychosocial risk factors evaluation method of the INSHT (Martín and Pérez, 1997), using canonical regression, we found that several psychosocial factors such as role definition, mental workload, interest in the workers, and supervision / participation predict two types of mobbing: personal mobbing and work-performance-related mobbing.     

Job demands, job resources and individual innovation at work: going beyond Karasek's model?

The job demands-control model is one of the most recognized models in occupational stress research. It has, however, provided contradictory results, and the active learning hypothesis derived from this model has been under-researched in comparison with research on the stress hypothesis. The main aim of this study is to test the Job Demands Resources Model in the prediction of individual innovation at work as an active coping strategy. Results with hierarchical multiple regression analyses provide empirical support for this model. We found a positive relationship between job demands and individual innovation in situations characterized by high job resources. Finally, we discuss the limitations and practical implications of this study.     

Emotional lability, negative affect and emotional regulation in children of anxious mothers

This study examined the role of emotional lability and negative affect and emotional regulation in the relation between maternal trait anxiety and attentional and social problems, and internalizing and externalizing symptoms of 275 six- to eleven-year-old children. The results indicated a direct moderating effect of emotional regulation in the relation between maternal anxiety and externalizing behaviour and that lability and negative affect moderated the relation between maternal anxiety and attention and social problems and somatic complaints. The links between maternal anxiety and withdrawal and anxiety/depression symptoms were also mediated by lability and negative affect. This mediation was independent of emotional regulation in the first case, and it depended on emotional regulation with regard to anxiety/depression symptoms.     

The influence of psychological variables on sports performance: assessment with the Questionnaire of Sports Performance-related Psychological Characteristics

The purpose of this research was to observe the relationship among psychological variables and three important issues in sports competition: achieving success, long-term continuance and sustaining injuries. Three studies were carried out with three groups of athletes from the areas of judo, football and swimming, using the Questionnaire of Sports Performance-related Psychological Characteristics as the measuring instrument. The analyses carried out revealed significantly statistical associations between the perception of stress control and of self-confidence, and between achieving success, long-term continuance in competition sports and sustaining injuries. These results indicate the importance of psychological skills training to aid sports performance and prevent injuries, as well as the use of the above-mentioned questionnaire, which, with a limited number of items, measures a wide range of psychological variables in the specific context of sports.     

Internal structure and standardised scores of the Torrance Test of Creative Thinking

The present work sets out to study the internal structure of the Torrance Test of Creative Thinking (TTCT) and to establish standardised scores that will enable the test to be used in both a diagnostic and educational context. 649 students (319 girls and 330 boys), aged 5 to 12 years from various schools in Murcia and Alicante (SE Spain), took part in the study. The findings suggest that the psychometric characteristics of TTCT are satisfactory, and its internal structure can be attributed to three factors that are responsible for a high percentage of the variance (73.8%). The standardised score tables, which are provided for first time in this context, will be useful in the evaluation of creativity and the identification of students with high intellectual abilities.     

Quantitative numerical and lexical knowledge: evidence of double dissociation

The aim of this work was to explain the involvement of a specific brain injury in the numerical processing and calculation system. The method employed was > analysis and the administration of various cognitive neuropsychology tests. The results of this study revealed a double dissociation between quantitative numerical knowledge and qualitative or lexical numerical knowledge. Patient M.C. preserved quantitative numerical knowledge, as indicated by the results obtained in the numerical comprehension and calculation tasks. However, she showed a drastic deficit in qualitative numerical knowledge. On the other hand, patient M.L. preserved qualitative numerical knowledge, but she had serious problems in all the abilities that require internal manipulation of magnitude; that is, quantitative numerical knowledge. These results have two important implications, as conclusions: firstly, quantitative numerical knowledge may be made up of different elements susceptible to damage independently. And secondly, quantitative and qualitative numerical knowledge were functionally independent.     

Aging and strategic retrieval in a cued-recall test: the role of executive functions and fluid intelligence

Cued-recall in episodic memory was investigated in relation to low and high cognitive support at retrieval, executive function level and fluid intelligence level in 81 healthy adults divided first into two age groups (young and elderly adults). The first analyses showed that age-related differences were greater when a low cognitive support was provided to recall the words. An individual index of loss of performance when the number of cues was decreased was then calculated. Hierarchical regression analysis revealed that the executive functions measure (perseverative errors on the Wisconsin Card Sorting Test) was a better candidate than the fluid intelligence measure (Cattell's culture fair test) to account for the age-related variance of the size of performance loss. These findings suggest that age differences in implementing strategic retrieval may be mainly due to a decline in executive functions.     

Maintained attitudinal changes in nursing personnel after a brief training on suicide prevention

Nursing personnel (N = 317) working at a general hospital attended a 6-hour training program on suicide prevention. They answered anonymously pre- and post-training the Suicide Behavior Attitude Questionnaire (SBAQ), which comprises 21 visual analogue scale items divided in three factorial subscales. The results indicated there were positive changes in the attitudes and these gains were significantly maintained at the 6-month follow-up evaluation. Improvement was in the Feelings and Professional Capacity subscales (ANOVA; p = 0.0001 and 0.01, respectively). There was no change on the Right to Suicide subscale. Because attitudes influence the effectiveness of health care personnel interventions, our findings may have important implications for the development of suicide prevention programs.     

Adjudicative competence and comprehension of Miranda rights in adolescent defendants: a comparison of legal standards

Currently, there is considerable variability and ambiguity in legal standards pertaining to juveniles' comprehension of Miranda rights and their adjudicative competence. This study investigated rates of impairment under various proposed legal standards. One hundred and fifty-two young defendants aged 11-17 were assessed with Grisso's Miranda Instruments and the Fitness Interview Test-Revised. While over half of defendants aged 15 and under were classified as impaired in adjudicative capacities when adult norms were applied, significantly fewer adolescents were classified as impaired when adolescent norms were applied or a standard of "basic understanding and communication." Also, while over half of defendants aged 15 and under were classified as impaired in their comprehension of Miranda rights when both understanding and appreciation of Miranda rights were required, significantly fewer youth were classified as being impaired when only understanding was required. The implications of these findings are discussed.     

Thinking of things unseen: infants' use of language to update mental representations

One of the most distinctive characteristics of humans is the capacity to learn from what other people tell them. Often new information is provided about an entity that is not present, requiring incorporation of that information into one's mental representation of the absent object. Here we present evidence regarding the emergence of this vital ability. Nineteen- and 22-month-old infants first learned a name for a toy and later were told that the toy had undergone a change in state (it had become wet) while out of view. The 22-month-olds (but not the 19-month-olds) subsequently identified the toy solely on the basis of the property that they were told about but had never seen. Thus, before the end of their 2nd year, infants can use verbal information to update their representation of an absent object. This developmental advance inaugurates a uniquely human and immensely powerful form of learning about the world.
