Factor structure and behavioural correlates of the Psychopathy Checklist-Revised [PCL-R] in a Brazilian prisoner sample

The present study examines the reliability, factor structure, and criterion-related validity of Hare (2003) Revised Psychopathy Checklist [PCL-R] in a Latin American forensic context. Brazilian male inmates (124) were administered the PCL-R, along with relevant subscales of an inventory of normal personality [Personality Factorial Inventory], an intelligence scale [Standard Progressive Matrices], and a semi-structured interview based in DSM IV. Criminal offence records were obtained from prison files. Several theoretical factorial structures for the PCL-R were tested and compared. A bifactor model with three factors, one general factor reflecting the overlap across all items, and two independent subfactors reflecting the unique covariation among particular groups of items, shows the better fit. Overall scores on the PCL-R correlated with the number of criminal offenses committed by participants. No significant correlations were found between PCL-R scores and personality or intelligence measures. It was concluded that the PCL-R is a reliable and valid instrument for the assessment of psychopathy in the Brazilian male forensic population.     

How impulsiveness, trait anger, and extracurricular activities might affect aggression in school children

Individual differences in personality traits such as impulsivity and trait anger as well as environmental variables have an impact on aggressiveness. We tested a model incorporating the related variables of impulsiveness, trait anger, and aggression and incorporated the possible mediating influences of leisure-time activities. Regression analyses of data from 1129 pre-adolescents and 1093 adolescents (55.4% females) from a study evaluating the Spanish version of the Buss and Perry aggression questionnaire (AQ; Santisteban, Alvarado, & Recio, 2007) showed a relation between impulsiveness (Barratt Impulsiveness Scale) and aggression (AQ). Trait anger (Spielberger’s State-Trait Anger Expression Inventory), the time spent watching TV and playing video games, and the time spent doing homework (all related to impulsiveness) also are related to physical, as well as verbal aggression (with low to moderate coefficients). Multiple mediation analyses confirm that media violence exposure and homework, respectively, can have aggravating and attenuating effects on self-reported aggression. These results provide key variables for longitudinal studies which could reveal the causal nature of the results found with our cross-sectional design.     

Learning approaches, self-regulation and achievement in three European universities

The current study seeks to analyze the relationship between learning approaches, self-regulation and performance. Data are gathered from three public European universities, one from the UK (University of Wales Institute, Cardiff) and two from Spain (Universities of Almeria and Granada). Two self-report measurements were used to collect information, the R-SPQ-2F questionnaire and the IATLP Scales. Results indicate that learning approaches are related to self-regulation and to academic performance. Different relationships with learning approaches are obtained depending on the type of performance analyzed (conceptual, procedural, attitudinal), which may account for divergent conclusions in other research studies. New lines of research are proposed based on the conclusions.     

From residential care to school: peer relationships at school of minors in residential care

In this study, peer relationships of minors in residential care in a school context are analysed, both from the perspective of the peers and the teachers. Using a sociometric test and an evaluation protocol for teachers in 50 classrooms, a sample of 60 minors in care is compared to a normative sample of 843 minors. The results show that minors in residential care have a higher rate of rejection by their classmates in academic activities, but not for leisure ones. Furthermore, in comparison with the normative sample, they are more frequently described with negative adjectives. There is a high level of agreement between the peer evaluation and that of the teachers in the most visible aspects in the classroom. The implications of these results for the improvement of the adjustment of this group are discussed.     

If Internet credibility is so iffy, why the heavy use? The relationship between medium use and credibility

Just because we use the Internet extensively, does it mean we think it is very credible? Not necessarily. Results of a large survey (N = 1,089) reveal that Internet credibility is predicted by Internet use for information purposes but not by Internet use for entertainment purposes. Further, newspaper use appears to predict individuals' Internet use and perceptions of Internet credibility.     

Influence of articulation rate on two memory tasks in young and older adults

This study investigated the relation between phonological loop functioning and age. Phonological loop is a time-based subsystem of the Working Memory Model of Baddeley and Wilson, which uses rehearsal of information as an active process to avoid phonological decay. Performance differences were examined between young and older adults in two speech-based memory tasks, such as the immediate serial recall of words and the Digit Ordering Task. Analysis showed that performance on both tasks was lower for the older group. Articulation rate was also measured to test the hypothesis that the impairment of some cognitive functions in adults can be associated to their slowness or the greater time needed by older adults for the rehearsal process. A significant negative correlation was found for articulation rate with age. When the effect of articulation rate on Serial Recall and Digit Ordering Tasks was partialled out, the difference between the two groups was eliminated.     

Making Sense of Abuse: Case Studies in Sibling Incest

This case study focused on the process of making sense of abuse in two Latino families experiencing sibling incest. Participants included five male children ranging in age from 8 to 15 that were members of two families dealing with the issue of sibling incest. The purpose of this study was to build understanding of how families experience sibling incest and its role in their families. Clinical data from therapy sessions was analyzed to reveal that families made sense of the incest in different ways including abuse as normal and abuse as a mistake. Central concepts that explained how the families responded to the sibling incest included (1) level of family cohesion, (2) role of secrecy, and (3) view of outside systems. The findings suggest that treatment needs to include an in-depth assessment regarding these issues.     

Neurobehavioral functioning in children with fetal alcohol spectrum disorder.

Neurobehavioral functioning of 50 Canadian children diagnosed with Fetal Alcohol Spectrum Disorder (FASD) was evaluated. The aims of this study were to identify specific areas of weakness in neurobehavioral functioning, to examine whether neurobehavioral functioning was related to various predictor variables, and to determine which measures differentiated between children given a brain score of 2 (possible dysfunction) and 3 (probable dysfunction). Participants displayed difficulties with many aspects of intelligence, memory, executive functioning, and attention. Measures of Full scale and Verbal IQ, as well as memory for faces and numbers differentiated between children with a brain 2 and 3 ranking. An interesting pattern of strengths and weaknesses emerged as well as significant differences related to ethnic background, gender, and age. Aboriginal children and Caucasian children with FASD do not appear to show the same pattern of strengths and weaknesses in neurobehavioral functioning.     

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.
