Movie smoking exposure and smoking onset: a longitudinal study of mediation processes in a representative sample of U.S. adolescents.

The authors tested 2 mechanisms for the relation of movie smoking exposure with onset of cigarette smoking in adolescence. Longitudinal data with 8-month follow-up were obtained from a representative sample of 6,522 U.S. adolescents, ages 10-14 years. Structural modeling analysis based on initial nonsmokers, which controlled for 10 covariates associated with movie exposure, showed that viewing more smoking in movies was related to increases in positive expectancies about smoking and increases in affiliation with smoking peers, and these variables were both related to smoking onset. A direct effect of movie exposure on smoking onset was also noted. Mediation findings were replicated across cross-sectional and longitudinal analyses. Tests for gender differences indicated that girls showed larger effects of movie exposure for some variables. Implications for policy and prevention research are discussed.     

A Bayesian approach to the argument from ignorance.

In this paper, we re-examine a classic informal reasoning fallacy, the so-called argumentam ad ignorantiam. We argue that the structure of some versions of this argument parallels examples of inductive reasoning that are widely viewed as unproblematic. Viewed probabilistically, these versions of the argument from ignorance constitute a legitimate form of reasoning; the textbook examples are inductive arguments that are not unsound but simply weak, due to the nature of the premises and conclusions involved. In an experiment, we demonstrated some of the variables affecting the strength of the argument, and conclude with some general considerations towards an empirical theory of argument strength.     

Intervention-based school psychology services: Training for child-level accountability; preparing for program-level accountability

This research evaluated the outcomes of a school psychology training practicum by replicating intervention-based service delivery procedures established in prior research. The key components include describing a service delivery model, teaching the model, deriving practice guidelines that fit the model, supporting trainees in carrying out the steps, and evaluating the outcomes. Procedures to determine outcomes were based on single-case design facets including accountability design (A-B), visual analysis of graphic data, and social validity ratings. Meta-analysis techniques included calculation of effect sizes and percent of nonoverlapping data (PND). Goal attainment scaling (GAS) also was used to summarize outcomes. The analyses indicated that the interventions led to positive changes for most children. For example, the median effect size was 1.42 across cases. Social validity evidence showed that consumers judged the outcomes positively. Achieving ideal baseline and technical adequacy checks (e.g., observer agreement, intervention adherence) represented challenges for many consultations. The contributions of the study include describing methods for child- and program-level accountability in training and areas for improvement including further supporting the completion of technical checks for intervention services.     

Friendship and loneliness among bullies and victims: Data from seven countries

Research suggests that the relationship between school bullying and its various risk factors should be clearer among girls than boys, and should become stronger with age, as roles within the peer group stabilise. This paper tests this theory by comparing sex, school type, and bully/victim status differences in friendships and playground social interactions, using data from nine surveys in seven countries: China, England, Ireland, Italy, Japan, Portugal, and Spain. A total of approximately 48,000 children completed various translations of the Olweus Bullying Questionnaire. Small but generally consistent main effects were found for sex and school type (boys and primary pupils enjoyed playtimes more and had more friends, but were also more likely to spend playtimes alone). Larger effects were consistently found for bully/victim status (victims were significantly worse off on all the measures in all the samples where a difference was found, while bullies and neutrals did not differ consistently), but the interactions between these factors varied widely between samples and there were few consistent patterns. It is concluded that bullying is a universal phenomenon with many negative correlates for victims and few (if any) for bullies, but that there are cultural variations in the way that bullying is related to sex, age, and social support.

Do You Need to Have Them or Should You Believe You Have Them? Resources, Their Appraisal, and Well-Being in Adulthood

How young, middle-aged, and young-old adults use individual resources to cope with challenges and changes in their lives is likely to influence the ways they will approach late life. One of the most important barriers to using available resources is the subjective appraisal of the situation, of the available resources, and of the potential use of these resources. The present study based on 2,313 individuals (25–74 years) from the National Survey of Midlife Development in the United States (MIDUS) examines the structural relations between available social, financial, and health resources, the subjective appraisal of these resources, and well-being in young, middle-aged, and young-old adults. The results indicate that the subjective appraisal of resources mediates the effects of available social, financial, and health resources on well-being irrespective of age groups. The discussion focuses on the importance of the appraisal of available resources as a precondition to successfully cope with stress, and points out avenues for intervention research.     

Prospective memory and ageing: Is task importance relevant?

Memory for activities to be performed in the future, i.e., prospective memory, such as remembering to take medication or remembering to give a colleague a message, is a pervasive real‐world memory task that has recently begun to attract the attention of numerous researchers. Age effects in prospective memory have been found particularly in complex paradigms requiring participants to remember to switch between several subtasks in a limited time period (e.g., Kliegel, McDaniel, & Einstein, 2000). Here, most of the older adults try to complete one or two subtasks and to forget the prospective instruction to work on all subtasks. Since recent findings in this context show that one profits from tips regarding the relevant task in complex double tasks, it seems likely that age effects in prospective memory tasks might also be due to the lack of information about the importance of the prospective task. To test this hypothesis, the importance of the prospective task was varied in the present study with 104 young and old participants by providing motivational incentives to interrupt and switch during the introduction phase (plan formation) as well as during the execution phase. Also, interindividual differences regarding nonexecutive as well as executive cognitive resources were analysed, thus allowing estimation of the relationship between these factors and (age‐related) performance in complex prospective remembering. The results show age effects in favour of the younger group in all task components of the complex prospective multitask. In contrast, there was no effect of the present experimental manipulation of motivational incentives. Finally, in regression analyses, intention formation, in particular, was found to be a significant predictor of intention execution, explaining most of the age‐related variance. In sum, our results specifically highlight the fundamental importance of adequately planning the complex intention and do not support the hypothesis that age‐related decrements in performance are reflecting a lack of motivation in the present complex prospective memory paradigm.     

The Soldier Fitness Tracker: global delivery of Comprehensive Soldier Fitness

Carefully implemented technology strategies are vital to the success of large-scale initiatives such as the U.S. Army's Comprehensive Soldier Fitness (CSF) program. Achieving the U.S. Army's vision for CSF required a robust information technology platform that was scaled to millions of users and that leveraged the Internet to enable global reach. The platform needed to be agile, provide powerful real-time reporting, and have the capacity to quickly transform to meet emerging requirements. Existing organizational applications, such as "Single Sign-On," and authoritative data sources were exploited to the maximum extent possible. Development of the "Soldier Fitness Tracker" is the most recent, and possibly the best, demonstration of the potential benefits possible when existing organizational capabilities are married to new, innovative applications. Combining the capabilities of the extant applications with the newly developed applications expedited development, eliminated redundant data collection, resulted in the exceeding of program objectives, and produced a comfortable experience for the end user, all in less than six months. This is a model for future technology integration.     

Role of event centrality and emotion regulation in posttraumatic stress disorder symptoms among internally displaced persons

Background: Event centrality and emotion regulation in relation to posttraumatic stress disorder (PTSD) have been documented in various global samples especially in Western cultures; but internally displaced persons (IDPs) still constitute an underrepresented population in psychotraumatology literature. This study tested the roles of event centrality and emotion regulation strategies (cognitive reappraisal and expressive suppression) in PTSD symptoms among IDPs in Nigeria.

Design: The multi-group cross-sectional design was adopted.

Methods: Tiv language versions of the Centrality of Events Scale, Emotion Regulation Questionnaire, and Harvard Trauma Questionnaire were completed by 859 IDPs in two camps located in Benue State, North-central region of Nigeria.

Results: Hierarchical multiple linear regression results indicated that event centrality positively predicted PTSD symptoms. Cognitive reappraisal was a negative predictor of PTSD symptoms while expressive suppression was a positive predictor of PTSD symptoms. Bonferroni corrections indicated that expressive suppression was the strongest predictor of total PTSD symptoms, avoidance/numbing symptoms, and hyper-arousal symptoms; but event centrality was the most robust predictor of PTSD intrusion/re-experiencing symptoms.

Conclusion: The findings underscore recent developments in psychotraumatology indicating that the extent to which individual differences impact the development of PTSD is essential in clinical psychology research and practice.
