Personality Trait Change in Adulthood

ABSTRACT— Recent longitudinal and cross-sectional aging research has shown that personality traits continue to change in adulthood. In this article, we review the evidence for mean-level change in personality traits, as well as for individual differences in change across the life span. In terms of mean-level change, people show increased self-confidence, warmth, self-control, and emotional stability with age. These changes predominate in young adulthood (age 20–40). Moreover, mean-level change in personality traits occurs in middle and old age, showing that personality traits can change at any age. In terms of individual differences in personality change, people demonstrate unique patterns of development at all stages of the life course, and these patterns appear to be the result of specific life experiences that pertain to a person's stage of life.     

Emergent Processes in Group Behavior

ABSTRACT— Just as neurons interconnect in networks that create structured thoughts beyond the ken of any individual neuron, so people spontaneously organize themselves into groups to create emergent organizations that no individual may intend, comprehend, or even perceive. Recent technological advances have provided us with unprecedented opportunities for conducting controlled laboratory experiments on human collective behavior. We describe two experimental paradigms in which we attempt to build predictive bridges between the beliefs, goals, and cognitive capacities of individuals and patterns of behavior at the group level, showing how the members of a group dynamically allocate themselves to resources and how innovations diffuse through a social network. Agent-based computational models have provided useful explanatory and predictive accounts. Together, the models and experiments point to tradeoffs between exploration and exploitation—that is, compromises between individuals using their own innovations and using innovations obtained from their peers—and the emergence of group-level organizations such as population waves, bandwagon effects, and spontaneous specialization.     

Serotoninergic regulation of emotional and behavioural control processes

5-Hydroxytryptamine (5-HT, serotonin) has long been implicated in a wide variety of emotional, cognitive and behavioural control processes. However, its precise contribution is still not well understood. Depletion of 5-HT enhances behavioural and brain responsiveness to punishment or other aversive signals, while disinhibiting previously rewarded but now punished behaviours. Findings suggest that 5-HT modulates the impact of punishment-related signals on learning and emotion (aversion), but also promotes response inhibition. Exaggerated aversive processing and deficient response inhibition could underlie distinct symptoms of a range of affective disorders, namely stress- or threat-vulnerability and compulsive behaviour, respectively. We review evidence from studies with human volunteers and experimental animals that begins to elucidate the neurobiological systems underlying these different effects.     

New paradigms for assessing emotional intelligence: theory and data

This article describes the development and validation of 2 measures of emotional intelligence (EI): the Situational Test of Emotional Understanding (STEU) and the Situational Test of Emotion Management (STEM). Study 1 (N=207 psychology students) examines multiple sources of validity evidence: relationships with EI, vocabulary, personality, and emotion-related criteria. Study 2 (N=149 white-collar volunteers) relates STEU and STEM scores to clinical symptoms, finding relationships to anxiety and stress for both tests, and to depression for the STEM. It is concluded that new performance-based approaches to test development, such as the present ones, might be useful in distinguishing between test and construct effects. Implications for expanding theory and for developing EI interventions are discussed.     

Measuring Treatment Outcome for Children with Serious Emotional Disturbances: Discriminant Validity and Clinical Significance of the Child and Adolescent Functioning Assessment Scale

We investigated the use of a popular measure, the Children and Adolescent Functional Assessment Scale (CAFAS), in treatment outcome research. The sample included 70 children who had been discharged from an elementary therapeutic classroom (Intensive Mental Health Program). Significant relationships were found between decreases in CAFAS scores and optimal educational placement, contributing to evidence of the scale’s discriminant validity. Clinically significant change in CAFAS scores was also investigated, with a 30 point change in score most accurately discriminating between placements after discharge. Further investigations of real world outcomes versus changes in score on this measure are warranted.     

The Intensive Mental Health Program: Development and Structure of the Model of Intervention for Children with Serious Emotional Disturbances

In order to meet the challenging needs and behaviors of children with Serious Emotional Disorders (SED), a school and community based Intensive Mental Health Program (IMHP) was developed and evaluated. We describe the conceptual framework, treatment principles, and model for service delivery for psychological and educational interventions under the umbrella of the IMHP. The program illustrates a model of comprehensive services for children with SED.     

Description of Exemplar Cases in the Intensive Mental Health Program: Illustrations of Application of the Therapeutic Model

We describe cases from the clinical records in the Intensive Mental Health Program to illustrate the diverse presenting problems, intervention strategies, therapeutic process, and outcomes for children receiving services in this school-based, community-oriented treatment model. Cases reflect varying degrees of treatment response and potential factors that influence the fluctuating levels of emotional disturbance and impaired functioning in the home, school, and community.     

Stop Thinking and Start Doing: Switching From Cognitive Therapy to Behavioral Activation in a Case of Chronic Treatment-Resistant Depression

Several recent investigations have demonstrated that Cognitive Therapy (CT) and Behavioral Activation (BA) are both efficacious treatments for depression (Butler, Chapman, Forman, & Beck, 2006; Dimidjian et al., 2006; Dobson, 1989; Gloaguen, Cottraux, Cucherat, & Blackburn, 1998; Hollon, Thase, & Markowitz, 2002; Jacobson et al., 1996). This investigation focuses on the treatment of Mr. X, a 62-year-old man with chronic treatment-resistant depression and comorbid personality pathology. After a course of 21 sessions of CT, treatment was switched to BA. We present daily mood data from 147 days of each treatment. Generalized least squares analyses of these time series data demonstrated that BA was associated with improved mood and these results were supported by clinical observation of improved functioning during the course of BA. We hypothesize that efforts at cognitive restructuring had an iatrogenic effect on this client and paradoxically triggered depressive rumination; these failed efforts provided further evidence in support of his underlying defectiveness schema. We also speculate that this client's dependent personality ran counter to CT's emphasis on autonomous homework assignments. Future randomized clinical trials are needed to investigate if nonresponders to CT benefit by switching to BA.
