Is personality stable in adolescence? Disentangling time-invariant and time-varying factors of personality in a trait–state–occasion model

This study applied trait–state–occasion (TSO) modelling to investigate the extent to which inter-individual differences in personality were accounted for by time-invariant and time-varying factors during adolescence. The participants were 753 high school students, and only 661 students were followed for 4 years. The mean age in the first year was 15.23 years and 52.8% were females. The results showed that the full TSO model had the best representation of adolescent personality, and the means of the proportions of variance explained by trait factors for the Big Five ranged between 56% and 83%, suggesting that inter-individual differences in personality are mainly accounted for by stable trait variance over the course of adolescence. Furthermore, the five dimensions of personality differed not only in the amounts of trait variance but also in the stability of time-varying factors. These findings have significant implications for personality research.     

Making plans for future success: a timeline tool feasibility study

Many adolescents have hopes of college graduation, independent living, and satisfying careers. Career preparation is an important component that can facilitate these desires. However, many adolescents do not achieve these hopes in their desired timeframes due to interruptions, such as unplanned pregnancies. As illustrated by the Theory of Adolescent Sexual Decision-Making Influencing Teen Pregnancy (Weiss, 2012. Who will listen? Rural teen pregnancy reflections. The Journal for Nurse Practitioners, 8, 804–809. doi:10.1016/j.nurpra.2012.02.028), desiring future success can promote low-risk decision-making. Based on this theory, a Getting Plans Started (GPS) Timeline Tool (GPS Timeline©) was developed to help adolescents plan for future success by using a time perspective and, thereby, avoid interruptions. The purpose of this paper is to describe the GPS Tool©, how it might be used, and a study to determine the feasibility of using the GPS Tool©. Thirty adolescents found the tool easy to use and effective in helping them plan for the future. Their responses indicated almost unanimous desires for college graduation and independence with strong confidence in achieving their plans, but their responses also indicated a need for more effective planning to achieve their desired goals.     

Religion and the Acceptability of White‐Collar Crime: A Cross‐National Analysis

This article examines whether shared religious beliefs and religious social relationships (Durkheim) and belief in a personal, moral God (Stark) negatively affect attitudes toward the acceptability of white‐collar crime. In addition, using a large cross‐national sample and estimating multilevel models, we test whether effects are conditional on modernization and religious contexts characterized by belief in an impersonal or amoral God. Shared religious beliefs and the importance of God in one's life are negatively related to the acceptability of white‐collar crime. These effects, however, weaken in religious contexts characterized by belief in an impersonal or amoral God as do the effects of religious social relationships and belonging to a religious organization; modernization, on the other hand, does not have a moderating effect. In short, religious belief is associated with lower acceptance of white‐collar crime and certain types of religious contexts condition this relationship.     

Future Expectations Among Adolescents: A Latent Class Analysis

Future expectations have been important predictors of adolescent development and behavior. Its measurement, however, has largely focused on single dimensions and misses potentially important components. This analysis investigates whether an empirically-driven, multidimensional approach to conceptualizing future expectations can substantively contribute to our understanding of adolescent risk behavior. We use data from the National Longitudinal Survey of Youth 1997 to derive subpopulations of adolescents based on their future expectations with latent class analysis. Multinomial regression then determines which covariates from Bronfenbrenner's ecological systems theory are associated with class membership. After modeling these covariates, we examine whether future expectations is associated with delinquency, substance use, and sexual experience. Our analysis suggests the emergence of four distinct classes labeled the Student Expectations, Student/Drinking Expectations, Victim Expectations, and Drinking/Arrest Expectations classes according to their indicator profiles. These classes differ with respect to covariates associated with membership; furthermore, they are all statistically and differentially associated with at least one adolescent risk behavior. This analysis demonstrates the additional benefit derived from using this multidimensional approach for studying future expectations. Further research is needed to investigate its stability and role in predicting adolescent risk behavior over time.     

Cluster Analysis Examination of Serial Killer Profiling Categories: A Bottom‐Up Approach

Two studies explored the validity of dichotomous classification of organised/disorganised serial killers and the four typologies (visionary, mission, hedonistic, and power/control) adopted by the Federal Bureau of Investigation (FBI). Tables documenting crime scene criteria were devised consisting of 50 typifying different crime scenes (Study 1) and 48 crime scenes (taken from the 50 crime scene criteria) with a further 10 motive‐based crime scene criteria (Study 2). Adopting content analysis, crime scenes depicted for 40 (Study 1) and 40 (Study 2) serial killers using secondary sources of data were dichotomously coded for the presence or absence of the crime scene criteria. These data were inputted for agglomerative hierarchical cluster using Ward's method as the clustering algorithm. Differences in the nature of clusters were found for male and female serial killers; however, there was no empirical support for the organised/disorganised classifications or the four typologies. The ‘bottom‐up’ approach resulted in clusters from the different crime scene criteria that helped to understand how these criteria were associated within the serial killer cohort considered. It is concluded that the resulting clusters in both studies support the notion of there being an underlying organised element to most serial murder and that serial murders differ according to the nature of disorganised crime scene criteria present.

Weighing in on risk factors for body dissatisfaction: a one-year prospective study of middle-adolescent girls

Body dissatisfaction is a common problem among adolescent girls that is linked to serious outcomes, including the development of eating disorders. This study tested to what degree five theorized risk factors (weight-related teasing, thin-ideal internalization, body mass index [BMI], self-esteem, and perfectionism) predicted prospective changes in body dissatisfaction. At baseline, 393 10th and 11th grade girls (M = 15.8 years) completed questionnaires and had their height and weight measured. One year later, 316 participants’ body dissatisfaction was reassessed (80.4% retention). Results suggested that self-esteem was the most potent risk factor, followed by BMI, when used to categorize girls into high- and low-risk groups for body dissatisfaction at follow-up. However, weight-related teasing, thin-ideal internalization, and perfectionism did not prove to be risk factors. These results suggest self-esteem and BMI are relevant variables for helping to identify middle-adolescent girls who may be at risk for subsequent increases in body dissatisfaction.     

Assessment of cognitive domains during treatment with OROS methylphenidate in adolescents with ADHD

Aim: To psychometrically assess cognitive domains in adolescents with ADHD during long-term open treatment with robust dosing of extended-release methylphenidate (OROS MPH).

Methods: Data were derived from a prospective clinical study of adolescent ADHD, employing the Cambridge Neuropsychological Test Automated Battery (CANTAB), before and after up to one year of treatment with OROS MPH. In the absence of placebo control, a similar age and gender group of youth without ADHD served as comparators.

Results: During the course of treatment with OROS MPH, ADHD youth’s performance significantly improved across multiple CANTAB tasks, including spatial working memory, rapid visual processing, verbal recognition memory, set shifting, and inhibition/vigilance. ADHD subjects’ scores in several CANTAB tasks, including spatial working memory, planning, and set shifting, were significantly more impaired at baseline compared to the non-ADHD comparison group; these significant differences were no longer seen at endpoint.

Conclusions: Statistically significant improvements in multiple cognitive domains were observed in a sample of adolescents with ADHD over the course of 12 months of robust treatment with extended-release methylphenidate. Rigorous, monitored stimulant treatment may be associated with objectively determined cognitive benefits; however, practice effects in this open trial cannot be ruled out. Further study on this important topic is warranted.     

Understanding the role of social support in trajectories of mental health symptoms for immigrant adolescents

This longitudinal study of 286, urban residing, first- and second-generation immigrant adolescents examined the degree to which acculturative stress is related to the developmental trajectories of mental health problems and the role of social support in this process. Participants were recruited when they entered 10th grade and two additional waves of data were gathered at 12-month intervals. Using individual growth curve modeling, the results show significant decline in internalizing mental health problems during the high school years. At the same time, greater exposure to acculturative stress predicted significantly more withdrawn/depressed, somatic, and anxious/depressed symptoms. Additionally, social support moderated the relation between acculturative stress and anxious/depressed symptoms. Gender and generation status differences were found only at baseline (10th grade).     

Attributions for Different Types of Traumatic Events and Post-Traumatic Stress Among Women

This study investigated the relationship of attributions to post-traumatic stress symptoms among women exposed to different types of traumatic events. Participants were 424 female undergraduates who previously experienced a serious accident, natural disaster, child abuse, or adult interpersonal violence. Path analysis indicated a significant indirect pathway from event type to post-traumatic stress through global attributions. Interpersonal-violence survivors exhibited the highest levels of global attributions and post-traumatic stress symptoms. Regression analyses revealed significant interactions between event type and attributions in predicting post-traumatic stress. Stable attributions were associated with increased symptoms in sexual-assault survivors and decreased symptoms in natural-disaster survivors. These findings have implications for improving cognitive interventions for survivors of different types of traumatic events.     

Is Fear of Crime Mainly Social and Economic Insecurity in Disguise? A Multilevel Multinational Analysis

Using the 2006 Eurobarometer data (representative sample of the European population, N = 16 306, 27 countries), we performed a multilevel analysis aimed at predicting fear of crime. A significant proportion of the variation in fear of crime was at country level. Of the individual predictors included, being a woman, being poorly educated, being unemployed, and being an urban dweller showed positive relations with fear of crime. Fear was highest among people who considered themselves to be socially marginal, among people with negative expectations regarding themselves and their country's future, and among people who considered their nation's welfare system to be unsatisfactory. Among the ecological predictors we took into consideration, nations' degree of economic inequality and low expenditure on education and on social protection showed a positive association with fear of crime, whereas the crime, immigration, and employment rates did not. Implications and limitations of this research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.
