Polydrug use trajectories and differences in impulsivity among adolescentsTrayectorias de policonsumo y diferencias en impulsividad entre adolescentes

Background/Objective: Although alcohol, tobacco and cannabis are the most widely consumed drugs, sparse data exist regarding polydrug use in adolescents and its relationship with impulsivity. This study aims to identify trajectories of polydrug use and analyze differences in impulsivity between them. Method: A total of 1,565 adolescents (54.4% males; mean age = 13.02, SD = 0.57) were annually assessed over three years using the Barratt Impulsiveness Scale, the Zuckerman Impulsive Sensation Seeking Scale, a Stroop Test and a Delay Discounting Task. Frequency of alcohol, tobacco, and cannabis use, intoxication episodes and problem drinking were also assessed. Polydrug trajectories were identified using latent class mixed modelling. To examine differences in self-reported and behavioral impulsivity two mixed multivariate analyses of covariance were used. Results: Three trajectories of substance use were found. The ‘Experimental use’ and the ‘Early use’ trajectories presented the lowest and highest impulsivity, respectively. Substance use increases in the ‘Telescoped used’ trajectory were associated with parallel increases in impulsivity. Conclusions: individuals with divergent patterns of substance use during adolescence differ in their impulsiveness, primarily in general impulsivity and sensation seeking. Present findings suggest the relevance of these facets as possible targets for interventions preventing the onset and escalation of substance use.     

"A right to lead": The role of leader legitimacy on group reactions to transgressive leadership

Research on the transgression credit shows that groups may sometimes turn a blind eye to ingroup leaders who transgress moral norms. Although there is substantial research investigating the underlying criteria of what makes a “good” leader, research often neglects to investigate the role of followers in leader-group dynamics. In this paper, we offer a novel approach to transgressive leadership by proposing that leader legitimacy is a key factor that determines whether followers’ reactions to transgressive leaders are positive or negative. Across two experiments, participants ascribed transgression credit only to transgressive ingroup leaders perceived as legitimate (Studies 1–2, total n = 308). Transgressive illegitimate leaders were viewed as more threatening to the group, were targeted for formal punishment, received less validation for their behavior, triggered negative emotions (anger and shame), and raised higher consensus for their removal from the leadership position than did legitimate leaders. This effect also occurred irrespective of the absence of formal social control measures implemented toward the transgressive leader (Study 2). Mediation analysis showed that leader illegitimacy triggered stronger feelings of group threat and stronger negative emotions which, consequently, fuelled agreement with collective protest against the transgressive leader. Theoretical and practical implications of these findings are discussed.

Plagiarism Allegations Account for Most Retractions in Major Latin American/Caribbean Databases

This study focuses on retraction notices from two major Latin American/Caribbean indexing databases: SciELO and LILACS. SciELO includes open scientific journals published mostly in Latin America/the Caribbean, from which 10 % are also indexed by Thomson Reuters Web of Knowledge Journal of Citation Reports (JCR). LILACS has a similar geographical coverage and includes dissertations and conference/symposia proceedings, but it is limited to publications in the health sciences. A search for retraction notices was performed in these two databases using the keywords “retracted”, “retraction” “withdrawal”, “withdrawn”, “removed” and “redress”. Documents were manually checked to identify those that actually referred to retractions, which were then analyzed and categorized according to the reasons alleged in the notices. Dates of publication/retraction and time to retraction were also recorded. Searching procedures were performed between June and December 2014. Thirty-one retraction notices were identified, fifteen of which were in JCR-indexed journals. “Plagiarism” was alleged in six retractions of this group. Among the non-JCR journals, retraction reasons were alleged in fourteen cases, twelve of which were attributed to “plagiarism”. The proportion of retracted articles for the SciELO database was approximately 0.005 %. The reasons alleged in retraction notices may be used as signposts to inform discussions in Latin America on plagiarism and research integrity. At the international level, these results suggest that the correction of the literature is becoming global and is not limited to mainstream international publications.     

Appreciation of Beauty and Excellence: Relationship with Personality,Prosociality and Well-Being

Appreciation of beauty and excellence (ABE) is one of the least studied character strengths. Therefore, this study aims at advancing the knowledge in this area by (1) developing a scale that measures the three categories of appreciation (i.e., beauty, moral excellence, and non-moral excellence), (2) assessing many of its psychometric properties, and (3) examining the relationship of ABE with personality, prosociality, and well-being. In Study 1, we create and assess an initial set of items measuring ABE. In Study 2, we examine the dimensionality of ABE, and test the internal consistency and validity of the scale. Moreover, we assess the relationships between ABE and personality, prosociality and well-being. In Study 3, we test the temporal stability of the scale. Results revealed that a three-dimensional model of ABE showed the best fit to the data. The scale showed good validity (construct, factorial, incremental) and reliability (internal and temporal). Finally, ABE yielded positive associations with prosociality and well-being, and demonstrated to be more than a linear combination of the Big Five factors of personality.     

Divergent and Convergent Validation of the Complicated Grief Prototype Narrative

Although there is a prototype narrative for complicated grief (CG), there are neither divergent nor convergent validity studies of its clinical value. We evaluated the CG prototype narrative using a sociodemographic questionnaire and the Clinical Interview for Complicated Grief Diagnosis. We first conducted a convergent validation analysis followed by a divergent validation analysis. Results showed that participants with CG identified significantly more with the complicated grief prototype narrative than participants without CG.     

Profiles of emotional intelligence and demotivation to attend school in Chilean adolescents

The aim of this study was twofold: to identify different emotional intelligence (EI) profiles and to verify possible statistically significant differences in school refusal factors that result in a demotivation to attend school. Participants were 2362 Chilean adolescents aged from 13 to 17 (M?=?15.25; SD?=?1.33), who completed the Trait Meta-Mood Scale-24 (TMMS-24) and the School Refusal Assessment Scale-Revised (SRAS-R). Cluster analysis identified four EI profiles: high scores in repair and low in attention, high scores in attention and low in clarity and repair, low EI and high EI. Students with high scores in attention and low in repair scored higher in the first three factors of the SRAS-R, whereas in the fourth factor of the SRAS-R, students with high EI had significantly higher scores. Emotional regulation seems to be one of the determinant factors to prevent the appearance of school refusal. Based on these findings, we recommend that EI training be a part of future programs to overcome school attendance demotivation issues.     

Personality and health‐protective behaviour

Over the last decades much research has been devoted to the analysis of psychosocial factors associated with the development of health problems. However, less attention has been paid to mechanisms explaining why people keep engaging in risky behaviours and do not develop, instead, those habits that could increase their quality of life. To answer these questions, two lines of research have been followed: the main hypothesis of the first line is that there are personality characteristics that predispose the development of certain patterns of behaviour. The second line is focused on the analysis of the psychological processes that, together with situational factors, explain what behaviour is initiated and how it is maintained or changed. The main purpose of this paper is to review these two lines of research: what their main contributions are and what the problems they face are. Copyright © 1999 John Wiley & Sons, Ltd.
