The five factor model of personality and alexithymia: A meta-analysis

The main objective of the study was to examine the relationship between the Five Factor Model of Personality and alexithymia. Data were collected from 25 studies, which included 30 independent samples, 1384 effect sizes, and 7440 participants. All analyses were conducted with random effects models. Greater neuroticism and lower extraversion, openness to experience, agreeableness, and conscientiousness were associated with higher cognitive alexithymia. Greater neuroticism and openness to experience were linked to lower affective alexithymia. Additionally, age moderated the relationship between the Five Factor Model of Personality and cognitive alexithymia, in that the association between neuroticism and alexithymia became stronger with age whereas the relations of extraversion, openness to experience, agreeableness, and conscientiousness with alexithymia became weaker with age.

Estimating Between-Person and Within-Person Subscore Reliability with Profile Analysis

Subscores are of increasing interest in educational and psychological testing due to their diagnostic function for evaluating examinees' strengths and weaknesses within particular domains of knowledge. Previous studies about the utility of subscores have mostly focused on the overall reliability of individual subscores and ignored the fact that subscores should be distinct and have added value over the total score. This study introduces a profile reliability approach that partitions the overall subscore reliability into within-person and between-person subscore reliability. The estimation of between-person reliability and within-person reliability coefficients is demonstrated using subscores from number-correct scoring, unidimensional and multidimensional item response theory scoring, and augmented scoring approaches via a simulation study and a real data study. The effects of various testing conditions, such as subtest length, correlations among subscores, and the number of subtests, are examined. Results indicate that there is a substantial trade-off between within-person and between-person reliability of subscores. Profile reliability coefficients can be useful in determining the extent to which subscores provide distinct and reliable information under various testing conditions.     

Taking Stock of the Diversity and Sense of Community Debate

Over the past couple of years, a debate has played out in the pages of the American Journal of Community Psychology concerning the relationship between two of Community Psychology's core values: promoting diversity and promoting a sense of community. This special section is to continue a discussion about diversity and community, both among the debate's initial contributors (Alex Stivala, Greg Townley, and Zachary Neal), as well as among others whose own work has touched on these issues (Anne Brodsky, Richard Florida, Jean Hill, and Roderick Watts). In this essay, I address some broad questions that have emerged through this discussion. First, because much has been written on the relationship between diversity and community, both in community psychology and in other disciplines, what do we know, or at least think we know? Second, since the constructs of diversity and sense of community are complex and multi‐faceted, how can definitions get in the way and how can we avoid talking past one another in this discussion? Finally, looking across the original papers that initiated this discussion, as well as the contributions in this special section, what path(s) forward do we have?     

主客体互倚性的成对模式及其检验

主客体互倚性模型（APIM）以成对数据作为分析单元,是成对数据分析的重要方法。基于APIM中的主体效应与客体效应,Kenny等人论述了APIM的四种成对模式：主体模式、客体模式、对偶模式与对比模式。通过定义客体效应与主体效应的比值为k,Kenny等人提出了定量指标,以分析主客体互倚性的成对模式。成对模式分析有助于简化数据结果、检验理论模型、解析群体互动过程。虽然k值的检验程序较为复杂,但APIM成对模式及k值的提出,对于成对数据分析,特别是家庭研究与组织心理学研究具有重要意义。     

Time pressure and group performance: Exploring underlying processes in the Attentional Focus Model

The Attentional Focus Model (Karau & Kelly, 1992) predicts that time pressure should lead group members to focus on a restricted range of task-relevant cues and to adopt task completion as their major interaction objective. Although this prediction has been supported in several studies (e.g., Karau & Kelly, 1992; Kelly, Jackson, & Hutson-Comeaux, 1997; Kelly & Karau, 1999; Parks & Cowlin, 1995), the exact processes that underlie information restriction have not been specified. We propose that two processes are involved. Specifically, the restriction of information may occur because time pressure affects the way in which information is initially encoded or attended to before a group enters its decision-making phase, or because group members filter out what they judge to be less important information during group discussion and decision making. We assessed both of these processes within a decision-making experiment where time pressure was manipulated prior to learning information that would be used to perform a task. Recall of information learned prior to group discussion did not differ by time pressure condition, arguing against an encoding process. In contrast, interaction data demonstrated information restriction by group members, arguing for a filtering process. Thought listings collected 1 min into the group discussion in some groups also supported a filtering process, as did questionnaire data. Implications of these findings for the Attentional Focus Model and for effective group decision making are discussed.

A Multivariate Associative Finite Growth Mixture Modeling Approach Examining Adolescent Alcohol and Marijuana Use

Theoretical and empirical substance use development research suggests that adolescent populations are not homogenous and can often be separated into subpopulations characterized by qualitatively different patterns of substance use development. This paper demonstrates the application of a multivariate associative finite latent growth mixture modelling approach to examine heterogeneity in patterns of adolescent alcohol and marijuana use and the influence of age, gender, parent, and peer substance use. Substance use problem outcomes were also examined. Participants were male and female adolescents (N = 1,044) ranging in age from 11 to 17 years at the first assessment (Mean age = 14.47; SD = 1.95). Individuals were 45% female and 82% Caucasian. Using growth mixture methodology, a 7-class model captured distinct simultaneous alcohol and marijuana use patterns over a 3-year period. Findings highlight the importance of examining subgroups of adolescent substance use, rather than focusing only on single samples.     

I feel,therefore you act: Intrapersonal and interpersonal effects of emotion on negotiation as a function of social power

We examine how emotion (anger and happiness) affects value claiming and creation in a dyadic negotiation between parties with unequal power. Using a new statistical technique that analyzes individual data while controlling for dyad-level dependence, we demonstrate that anger is helpful for powerful negotiators. They feel more focused and assertive, and claim more value; the effects are intrapersonal, insofar as the powerful negotiator responds to his or her own emotional state and not to the emotional state of the counterpart. On the other hand, effects of emotion are generally not intrapersonal for low-power negotiators: these negotiators do not respond to their own emotions but can be affected by those of a powerful counterpart. They lose focus and yield value. Somewhat surprisingly, the presence of anger in the dyad appears to foster greater value creation, particularly when the powerful party is angry. Implications for the negotiation and power literatures are discussed.     

A developmental typology of adolescent personality

The purpose of the current study is to examine whether Block's personality types (i.e. Resilients, Undercontrollers and Overcontrollers) are replicable as developmental trajectories. We applied a Latent Class Growth Analysis (LCGA) framework to five‐ annual‐wave data on a sample of early to middle adolescents (n = 923). Our results showed that Block's Resilients, Undercontrollers and Overcontrollers are indeed replicable as developmental trajectories across adolescence. These developmental types were related to problem behaviour in a similar way as types found in studies using cross‐sectional data. As such, Resilients reflected low levels of problem behaviour, Undercontrollers had high levels of delinquency and Overcontrollers had high levels of depression. Implications and suggestions for further research are discussed. Copyright © 2009 John Wiley & Sons, Ltd.
